Patent GB-2148720-A (GB)
Title: Device for massaging extremities, such as legs
Inventor: PEKANMAKI KALLE
IPC: A61H23/04
Filed: 1984-11-05
Abstract: A device for massaging extremities of the body, such as legs, and for activating fluid flows, said device consisting of consecutive annular, mutually connected elastic jacket bags (2-15) disposed to encircle the leg (1) and in which pressures can be produced with the aid of a pressure source (P) and a fluid, which cause a massaging effect. The intervening space (16) defined between the jacket bags (2-15) and the leg 15 also connected to the pressure source (P) and can therefore be pressurized, whereby the jacket bags (2-15) are with the aid of the pressure in the intervening space (16) simultaneously depletable of pressure and further, after the jacket bags (2-15) have been pressurized, the intervening space (16) is with the aid of the pressure in the jacket bags depletable of pressure. The drawback encumbering known devices of this type, i.e. control of the pressure by means of very complicated valve systems, is therefore avoided. <IMAGE>

Title: Gyroscopic devices
Inventor: BURDESS JAMES STONEHOUSE
IPC: G01C19/567
Filed: 1985-02-19
Abstract: A gyroscopic device comprising a resonator in the form of a disc, cylinder or like structure of circular outline, of a composition containing piezo-electric material and preferably made of a an integral mass of such material. The resonator is excited into dilatation-type vibration by electric currents applied to exciting electrodes electro-deposited in a regular pattern around the circumference of the structure, and these vibrations are sensed by detecting electrodes similarly deposited around the wall in a similar but angularly displaced pattern. A measure of any rate of turn which the structure is undergoing about its axis can be derived from the resulting phase shift of the electrical output from the detecting electrodes.

Title: Apparatus and method for transporting liquid utilising the potential energy of an operating fluid
Inventor: DORA TIBOR
IPC: F25D17/02
Filed: 1985-05-17
Abstract: Energy exchanges between fluids are produced in a system of vessels containing a pressure transmission piston (12) and cylinders (11) sealed from the atmosphere, in a succession of cycles in which liquid to be moved and pressurised operating liquid are alternately fed to individual chambers above and below the piston (12) respectively. In order to make up for the energy losses incurred in the course of the liquid transporting process in a mine cooling system, forces are applied via an actuating device (12') to the pressure transmission piston (12). To render this possible the actuating devices (12') of the particular cylinders (11) are interconnected by a common drive system (13), preferably composed of a crankshaft (17), a transmission gear (16) and an electric motor (19). <IMAGE>

Patent GB-2177538-A (GB)
Title: Electrically activated gas laser
Inventor: PREIN FRANZ
IPC: H01S3/036
Filed: 1986-06-13
Abstract: An electrically activated gas laser has a closed housing in which the gas chamber contains a catalyst for adjusting and maintaining a chemical gas equilibrium. The catalytic reaction is enhanced by exposing the catalyst surfaces and/or molecules which are not readily deposited to radiation from the laser or from an external source. The flow of gas over the catalyst is regulated, and admixtures which assist the catalytic reaction but do not bring it about are introduced into catalyst surfaces in addition to the catalytically active areas or centres provided for gas regeneration. These measures are especially useful at high laser energy densities and dissociation rates, and when supersaturation of the catalyst surface with unwanted molecules is to be prevented.
Patent GB-2182772-A (GB)
Title: A remote monitoring device
Inventor: BLOICE JOHN ANTHONY
IPC: G08B13/181
Filed: 1986-11-07
Abstract: A device for the remote monitoring of an object or of the presence of smoke comprises an IR transmitter (11, Fig. 1 not shown) for illuminating an object to be monitored with pulses of infra-red radiation, and an IR detector (12) for detecting the level of infra-red radiation reflected from the object. Circuit means (20 to 25) provide a signal E which is a function of the level of the detected radiation. A relay RLY2 establishes on one side of a capacitor C7 a reference potential at a predetermined initial level in the presence of an initial signal level E, a subsequent change in the level of signal E causing or tending to cause a corresponding change in the reference potential. Means not shown but including a relay RLY1 tend to compensate for any such change in the reference potential level to reestablish the reference potential at its predetermined level. Finally, further circuit means (26 to 30) compare the level of the reference potential with predetermined limits and generate an alarm signal if the reference potential level falls outside such limits. The result is that an alarm signal is only generated if the rate of change of the signal E is too great to permit compensation by the means including the relay RLY1. <IMAGE>

Title: Process of preparing propylene homo- or co-polymers
Inventor: ASANUMA TADASHI
IPC: C08F2/38
Filed: 1986-11-13
Abstract: To control the molecular weight of a propylene homo- or co-polymer at a constant level when subjecting propylene alone, or together with another  alpha -olefin, to bulk polymerization in the presence of hydrogen as a molecular weight modifier, the polymerization is performed in a reaction tank equipped with a reflux condenser, using liquid monomer as the reaction medium. The molecular weight is controlled at a desired level, by constantly measuring the quantity of heat removed from the reaction tank and constantly calculating the volume of hydrogen to be consumed, on the basis of the above-measured quantity of removed heat and the volume (X) of hydrogen consumed per unit amount of polypropylene, which volume (X) is obtained by utilizing the relation In eta =InX+A. (A being a constant and  eta being the intrinsic viscosity of the propylene polymer). Hydrogen is charged into the reaction tank in quantities corresponding to variations in the calculated quantity.

Title: Reinforcing and sound insulating plastic vessels
Inventor: LAWSON ALLAN
IPC: A47K3/00
Filed: 1987-02-19
Abstract: Methods of reinforcing and mounting plastic vessels, for example a bath 1, comprising coating a plastic shell of a vessel with a layer 6 comprising glass fibre rovings, polyester resin and a hardening catalyst, the resin and the catalyst being selected for low exothermicity, and mounting the vessel on a support cradle or cradles 4 which has ground engaging foot means 11 with insulating lower portions that minimise the transmission of sound from the bath to the ground. Such a bath is relatively rigid and avoids flexing problems. Using a resin and catalyst with a low heat of reaction allows the coating to be carried out in one or two layers so as to reduce cost and avoid distortion of the plastic substrate due to the heat of reaction. The layer also provides sound insulation to the vessel and fire resistant additives may be incorporated. <IMAGE>
