摘要:
A honeybee collector includes a collector body having a sidewall with an outer surface and an inner surface. The inner surface defines a brood frame slot and a funnel defined below the brood frame slot. The funnel is angled towards a bottom opening defined by a bottom rim of the sidewall. An upper rim of the sidewall defines a top opening leading into the brood frame slot, and the brood frame slot is sized to receive a brood frame. A catch bottle is used for catching bees. A connector couples a mouth of the catch bottle to the bottom rim of the collector body.

A method, system, apparatus, and media are directed to tuning a device. Values are stored for each of a plurality of device parameters based on device metrics. The device parameters are constraint-matched over changes to settings of the device parameters to identify at least one point within each range of the device parameters that optimizes a performance measure for the device. Tuning values are selected for each device parameter based on the identified point. The tuning values are provided for tuning the device. The device is tuned with roll-back based on the running values.

A interlocking paving unit has a top surface (2) and a plurality of side surfaces (4, 5), with at least one of the side surfaces (4, 5) of the paving unit being provided with at least one substantially vertically extending, substantially asymmetric protrusion (10). The protrusion (10) comprises a first ridge portion (11) and a second portion (12) being spaced apart by an intermediate portion (13). The protrusion (10) is locatable in a complementary recess on an adjacent paving unit, wherein the interengagement between the protrusion and the recess provides interlock between the paving unit and an adjacent paving unit.

A method forms a concrete block, particularly but not exclusively a composite block with a reflective fascia portion. The block is formed by a dry-cast technique, in which mixture for forming the block has a water/cement ratio less than or equal to 0.35, in combination with application of a compaction force so that the resultant block complies with compressive strength requirements set out in BS 6717: part 1: 1993.

The device is used for accommodating a planiform advertising carrier (10) with two bars (3,4) arranged on top of each other and for keeping the advertising carrier (10) tenterable. The advertising carrier is laterally tenterable, for lateral tentering. Further the advertising carrier (10) is provided at least on one side with a tentering device which comprises a rail (20) which takes laterally hold of the advertising carrier and a tentering device (70) by means of which the rail (20) is movable for the lateral tentering of the advertising carrier, the advertising carrier (10) being held on the other side against the tentering direction.

A connector assembly enables a dense grouping of contacts to be joined in one step to a printed circuit board (PCB) while assuring that impedances are matched among all components. A receptacle intended for mounting on the PCB matingly receives a plug which carries terminal contacts of multiple coaxial cable leads. The plug includes a honeycomb grounding block to engageably receive the outer conductor of each coaxial terminal, an inner conductive sleeve being electrically coupled to a signal lead by a first contact. Signal pin contacts within the receptacle and electrically coupled with the PCB are electrically coupled with each inner conductive sleeve when the plug is inserted into the receptacle. Likewise, ground pin contacts within the receptacle and electrically coupled with the PCB have second and third spaced resilient contacts, respectively, engaging the grounding block at distances farther from the nearer to the PCB than the first contacts. As the plug moves toward engagement with the receptacle, the ground pin contacts first move into engagement with the grounding block to initially discharge static electricity. Thereupon, the signal pin contacts engage associated inner sleeves of the coaxial terminals. In its final position within the receptacle, the ground pin contacts engage the grounding block nearer the PCB thant the location of engagement between the signal pin contacts and their associated inner sleeves thereby minimizing the possibility of ground loops.

摘要:
An information carrier for receiving at least one information data. The information carrier includes an inflatable hollow body made of a flexible, foldable material and a blower for blowing an air flow into the inner part of the hollow body. The blower is arranged in or on the hollow body in such a way that the air flow produced by the blower builds up an overpressure within the hollow body whereby the hollow body adopts a stationary and stable rectangular frame shape over which the information banner may be fastened, more particularly removably fastened, while at least partly covering the open space within the frame.
摘要:
Device for accommodating a planiform advertising carrier, for example an advertising carrier consisting of foil or similar material. The advertising carrier is tenterable between two bars (5, 6) whereas the bars (5, 6) are relative to each other movably accommodated by a frame (2).
摘要:
A controlled impedance connector assembly comprised of a mutually engageable plug and receptacle for termination of coaxial cable leads in a manner which enables rapid attachment to and detachment from a user board of a very large number of signal leads while ensuring an acceptable level of controlled impedance from the coaxial cable to the user board. The receptacle includes a backup plate and a plurality of metallized grounding segments fixed to the backup plate and having a plurality of spaced parallel terminal receiving bores therein extending between opposed surfaces. An insulation plate is fixed to each grounding segment and overlies one of the surfaces. A plurality of pin contacts are fixed to the insulation plate such that a head member extends into an associated terminal receiving bore and an oppositely directed tail member is adapted for termination at available circuitry. The plug includes a frame mounting a plurality of dielectric segments each having a plurality of parallel spaced terminal receiving bores extending between a front and a rear face. The dielectric segments are floatingly mounted for movement within defined limits in directions transverse to the axes of the terminal receiving bores.
