摘要:
A light table is used in connection with an underlying portable light source to illuminate a pattern disposed between the light table and an overlying fabric sheet. The light table includes a portable frame which spaces a translucent upper plate from a lower supporting surface over the light source. The frame also includes a downwardly facing peripheral frame channel which is utilized to clamp the overlying fabric sheet to the light table. More particularly, a plurality of resilient, one-piece hold-down clamps are placed about the periphery of the light table to firmly hold portions of the fabric sheet to the table to minimize relative movement therebetween. The clamps include a lower bracket bent into a resilient arch. The clamps snap into place about the periphery of the light table such that the arch-like lower bracket cooperates with the peripheral frame channel.

Vacuum regulator apparatus comprising: a valve that in use is arranged to admit air to a vacuum system that in operation is at a sub-atmospheric pressure, the apparatus being so arranged that an increase in the pressure in the vacuum system tends to cause less air to be admitted to the vacuum system by the regulator apparatus, and vice versa; means responsive to the position of the said valve arranged to give a first signal if air is being admitted at more than a first predetermined rate and a second signal if air is being admitted at less than a second predetermined rate lower than the first; and pressure-responsive means arranged to give a third signal if the pressure in the vacuum system is outside a predetermined range.

A mandrel for use in winding a web around an article, the mandrel including a support for a roll of the web, a handle rotatably attached at each end of the support and a brake which retards rotation of the support relative to at least one handle by an amount depending on the relative rotation between the handle and support which has already taken place.

The device and method for placement of an instrument, specifically electrodes, in the GI tract allows for placement of electrodes for gastric electrical stimulation into the gastric wall using endoscopic techniques. The device has one or more electrodes disposed on an elongated body having a pointed first end and a bolster disposed on a second end. When placed within the GI tract, the first end of the device extends through the gastric and abdominal walls, extending outside of the patient's body with the bolster in contact against the inner lining of the gastric wall to retain the device. Exposed electrodes contact the gastric smooth muscle. Insulated wires in electrical connection with-the electrodes run the length of the device body. Once the device is placed, the first end of the device body is removed to expose the wires, allowing electrical connection to an external electrical signal generator to provide electrical stimulus.

A spinning tubular projectile (STUP) is subcalibre to reduce both retard and the gyroscopic stability. The total effect is to reduce crosswind sensitivity and to obtain a better ballistic match with an armour piercing fin stabilized, discarding sabot (APFSDS) round. To reduce the range to that desired for a limited range practice round, the STUP is equipped with spin-damping fins on its surface near the projectile center of gravity.

The invention concerns novel glyceride esters of anti-bacterial halogenated phenols having the formula I in which Ra and Rb are independently (3-20C)alkyl or (3-20C)alkenyl; Rc and Rd are independently chloro or bromo; Re is hydrogen, chloro or bromo; and A is (1-6C)alkylene optionally bearing one or two (1-4C)alkyl substituents.The esters are of use in the prophylaxis and/or therapy of acne vulgaris. Pharmaceutical compositions for topical administration and processes for the manufacture of the esters are also provided.
摘要:
Concurrent or sequential application of an auxin transport inhibitor and a defoliating agent synergistically improve defoliation of crop plants and minimize crop plant regrowth. Preferably, the auxin transport inhibitor is a semicarbazone compound. The defoliating agent may be an ethylene response or ethylene-type response agent such as a phosphonic acid derivative. Most preferably, the semicarbazone compound is diflufenzopyr and the phosphonic acid derivative is ethephon (i.e., ethephon (2-chloroethyl) phosphonic acid).
