Title: Foot operated braking mechanisms for trolleys
Inventor: KALTEHERBERG GERHARD
IPC: B62B5/04
Filed: 1985-04-11
Abstract: Brake operating members 20a, 20b are moved downwards by levers 32 to operate braking mechanisms on a pair of wheels at opposite ends of a trolley. The levers 32 at each end of the trolley are coupled so that movement of one lever 32 also causes the other lever to actuate its associated brake operating member 20a or 20b. This is achieved by wedges 56 and 50 which move longitudinally to wedge one lever downwards, 30b in Fig. 3c, when the other lever is pivoted. In an alternative embodiment, only one lever is provided at one end of the trolley, the brakes at the opposite end being applied by a wedge acting directing on the brake operating member 206. <IMAGE>

Title: Radiation therapy apparatus using LED matrix
Inventor: LISON JONATHAN
IPC: A61N5/06
Filed: 1988-08-08
Abstract: A matrix of LEDs 20 provides a non-coherent light source as a substitute for more commonly employed laser devices and can be controlled to combine the operating characteristics of continuous beam helium neon lasers with the low cost convenience and high powered pulsed output of laser diodes. The radiation wavelength may be in the red or infra-red range. A switch (8), (Fig 1), allows selection of continuous and pulsed modes. In the continuous mode, a circuit 12 provides a continuous d.c. voltage on a rail 28 and a HEXFET 33 functions as a short circuit, the radiation intensity being varied by varying the amplitude of the d.c. voltage. In the pulsed mode, a fixed voltage is applied to rail 28, HEXFET 33 is pulsed on and off by a circuit 16, and the radiation intensity is varied by varying the pulse frequency and/or duty cycle. A timer (10), (Fig 1), turns off the power supply to terminate the therapy after a predetermined time. <IMAGE>
Patent GB-2223690-A (GB)
Title: Filter tubes
Inventor: WHITE ROGER STANLEY
IPC: B01D69/00
Filed: 1988-10-17
Abstract: Filtration systems which improve the retentate, permeate flow rates and surface area of tubular crossflow filtration systems use filter tubes comprising at least one layer of a porous membrane and a stellated inner surface. The filter tubes may have a membrane comprising two layers, the inner one (23) having finer pores than the outer one (21). In a preferred form the stellated inner surface has a spiral configuration which may have up to 500 turns per metre. The stellated surface provides an increase in surface area of about 25 percent over cylindrical tubes having the same diameter allowing a reduction in flow rate of about 50 percent over prior cylindrical filter tubes. The induced turbulence caused by the spirals further reduces the necessary flow rate.
Patent GB-2213131-A (GB)
Title: Holders for print ribbon carriers
Inventor: HAFTMANN JOHANNES
IPC: B41J32/00
Filed: 1988-12-07
Abstract: A holder for ribbon carriers in typewriters or other imprinting machines comprises a base plate (2) on which there are mounted retaining elements (7, 8) which can be swung away laterally. The retaining elements carry ribbon driving (12), braking (9) and tensioning (10, 11) elements. When the retaining elements have been swung away, a carrier (e.g. a ribbon cassette) can be inserted in the holder to engage pins (6) and a slot (5). When the retaining elements (7, 8) are swung back again, they surround the ribbon carrier in a shell-like manner, and the driving, braking and tensioning elements automatically engage the ribbon. Thus only the carrier with the used ribbon has to be thrown away while the driving, braking and tensioning elements remain on the device and can thus be often re-used. The production of the carrier with the ribbon thus becomes cheaper. <IMAGE>
Patent GB-886575-A (GB)
IPC: B01F3/08
Abstract: 886,575. Mixing liquids. FARBWERKE HOECHST A.G. Jan. 22, 1960 [Jan 22, 1959], No. 2508/60. Class 86. Liquids are mixed intimately, particularly in the production of emulsions, by injecting intermittently one of the liquids, which has been passed through a very fine filter, at a pressure of from 5 to 5000 atmospheres through a nozzle into the other liquid which flows continuously past the nozzle. The intermittent injection may be obtained by using a spring-loaded obturator on the nozzle, which opens only when the pump, e.g. a plunger or diaphragm pump, builds up sufficient pressure on the discharge stroke. As shown, one of the liquids passes from a vessel 1, through a filter 2, to a pump 3 which delivers it to a nozzle 7. The other liquid is supplied from a rotameter 10 to an annular space surrounding the nozzle 7 so that the mixture flows into a tube 9 surmounted by an overflow vessel 14 from which it flows to a collecting vessel 11. Some of the mixture may be recirculated by a pump 12 to the space around the nozzle 7. If the liquid in the vessel 1 is a mixture of immiscible liquids, e.g. oil and water, the homogenerty of the said mixture is maintained by a pump 13 which sucks from the inlet of the pump 3 and re-delivers the mixture to the vessel 1. If the compressibility of the liquid from the vessel 1 is low, it may be necessary to provide a vessel 5 in the high pressure line to prevent a too rapid rise or fall in pressure at the nozzle 7. The passage 8 leading to the tube 9 may be of various shapes according to the liquids being emulsified, it may be of greater diameter than the tube 9 or tapered as shown. The nozzle may be inverted to deliver in contraflow to the other liquid. The liquids may be substances or solutions or mixtures of substances which are liquid at room temperature, or need to be heated or cooled to bring them to liquid form for treatment, or may have endothermic or exothermic reactions, in which case the apparatus is provided with the necessary heating or cooling means. The pressures used and rates of flow depend on the nature of the liquids, but the emulsion remains in the tube 9 for a substantial time, i.e., a maximum of 120 minutes. Examples of processes for mixing various substances are given.

Abstract: In a radio transmission system, a pulse carrier from 12, 14 is modulated at 22 by intelligence signals from 34 to produce a pulse position modulated signal which controls a power switch 18 to supply discrete switched pulses for transmission by a wideband antenna 90 and local signals corresponding in polarity and time to the received signals are generated at 234, fig. 5 and a signal timing arrangement 227, 236-253 is responsive to the received signals and the local signals to produce a control signal for the local signal generator 234 and the local and received signals are multiplied at 226 for reproducing the original modulation at 260. The transmitted pulses may comprise a series of single pulses or a group of pulses. Secrecy in communication may be assured by adding a dither voltage from 33 to the intelligence signals and by using a shaping filter 82. The dither generator 228 at the receiver is synchronised to the generator 33 at the transmitter by receipt of special synchronization data or by sampling a number of received pulses. <IMAGE>
