摘要:
A cutting head assembly (12) for releasable and operable engagement with a corresponding clipper body (10) of an electric hair clipper (8), said clipper body (10) having a support tongue (34) pivotally mounted on a front end (9) of the clipper body (10), said cutting head assembly (12) having a tongue-receiving socket (42) for releasably receiving the support tongue (34) which socket (42) is defined, in part, by a strap (40) disposed on a bottom blade (14) of the cutting head assembly (12), the strap (40) having a central portion (43) with a bottom end (48) and an inner surface (47) opposing the bottom blade (14), characterized by means for preventing the cutting head assembly (12) from being releasably and operably engaged with other non corresponding clipper bodies, which means comprises at least one projection (52,118,136) disposed on the inner surface (47) of the central portion (43) and/or at least one slot (44,115,126) having an open end (44a) defined by the bottom end (48) of the central portion (43).
摘要:
A vibrating, rotating massager (1). The massager (1) includes a vibration means (20) mounted to a fixed axle (16) about which a spherical massager head (30) rotates. The vibration of the massage head (30) is isolated from the handle (10) of the massager (1) by elastomeric bushings (14).
摘要:
A garment iron (10) including a rear face (14) to which there is releasably attached a cord reel (17). The cord reel (17) includes a catch to retain it in its position mounted on the rear face (14). The cord reel (17) is hollow so as to provide a cavity which receives a beaker (28) which may be used to deliver water to the water reservoir of the iron (10). During use, the cord reel (17) and beaker (28) are removed from the rear face (14) so that the iron (10) may be vertically oriented, resting on its rear face (14).
摘要:
A combined washer and collar (35) supports a motor with respect to a top wall (13b) of a housing, the housing having downwardly extending shouldered bosses (34) which receive the washer and collar units (35) which have tabs (35b,35c) to facilitate preassembly to a motor frame member (23c).
摘要:
A new semiconductive material includes a suitable polymer or blend of polymers and a carbon black material in an amount of 4% to 25% based on the total weight of the semiconductive material, having a relatively low reticulate structure; and being essentially non-chemically surface-treated (having essentially a non-oxidized surface) such that the pH of the carbon black is at least 4.0, and generally about 5.0 to 8.5. These non-surface treated carbon blacks generally have a dry volatile content of about 3.0 or less and usually 2.5 or less. The particular carbon blacks suitable for the semiconductive materials of the invention are essentially non-surface treated, have a midrange value for dry volume resistivity, and have a nitrogen surface area A in m²/g greater than or equal to 1.75 x + e x/37 where x is the DBP absorption of the carbon black in cm³/100 grams. Such carbon blacks decrease the annealing times needed to less than about 3 minutes, and generally in the time period of less than 1 minute.
摘要:
An improved method of assembling conventional scales, including bathroom scales, is provided by employing an improved spring for connecting the upper housing to the bottom pan. The upper housing may now be connected to the bottom pan with a simple downward force imposed on the improved spring thereby hooking the bottom of the spring to the bottom pan and mateably engaging the tapered top of the spring in an extruded hole in the upper housing. The improved spring is tapered at the top end to mateably engage the extruded hole in the upper housing and includes only one hook on the bottom end for engagement with the bottom pan. The improved spring enables easier and faster assembly of conventional scales thereby reducing labor and production costs.
摘要:
A carburettor (10) with inbuilt governor for speed control of an engine which comprises a throttle valve (16) actuated by a diaphragm (20) responding via a fluid line (25) to air pressure varying with engine speed, and also comprising a device (26) responding to air pressure varying with engine speed and connected in a duct (27) serving to vent said fluid line, said device including valving means (31) to control the degree of venting of said fluid line depending upon the response of said device to air pressure changes.
摘要:
A governor for a carburettor (10) having a throttle valve (16) to control the speed of an engine, in which the governor comprises a pneumatic device (21) connected to the throttle valve and having a working chamber (22) vented by an orifice (26), a closure valve (27) for the orifice, and electrical means (Fig. 4 or Fig. 5) responding to engine speed and to a predetermined desired speed of the engine controlling operation of the closure valve to effect through said pneumatic device changes in engine speed to correspond it to the predetermined desired speed.
