Patent GB-2019625-A (GB)
Title: Security cases
IPC: G08B15/02
Filed: 1979-04-17
Abstract: A security case has a protective device such as canister 6 which can emit smoke and dye both inside and outside the case, after a press- button 7 is pressed by a person carrying the case, if it is snatched by a thief. This only happens if button 7 is pressed continuously for one or two seconds, determined by a first time delay circuit 11, so that accidental pressing is ineffective. The emission of smoke and dye is further delayed for about five or ten seconds by a second time delay circuit 12, so that a thief can get a certain distance after the case is snatched from the carrier, and the carrier is not engulfed in smoke and dye. <IMAGE>

Patent GB-2030428-A (GB)
Title: Speech signal transform coding
IPC: G10L19/00
Filed: 1979-08-21
Abstract: To improve the speech quality at lower bit rates within a digital communication system in which the coefficients of a frequency transform (e.g. discrete cosine transform) are adaptively encoded with adaptive quantization and adaptive bit-assignment, the adaptation is controlled by a short-term spectral estimate signal formed by combining the formant spectrum and the pitch excitation spectrum of the coefficient signals.
Patent GB-2033575-A (GB)
Title: Investigating substances in a patient's bloodstream
IPC: A61B5/00
Filed: 1979-08-24
Abstract: Investigation of substances such as oxygen, CO2 or glucose in a patient's bloodstream by passing the substances transcutaneously to a sensor is accompanied by a bloodless assessment of capillary blood flow rate, so that a warning indication 13 may be provided of any reduction in capillary blood flow rate (due to shock or other physiological conditions), under which reduced flow condition the detected amount of the substance does not represent the true amount present in arterial blood. Optical measurements, (Figures 1 and (A 2), or impedance measurements, (Figure 3), are used for the bloodless assessment of capillary blood flow rates. In the former case optical radiation from LED 7 is backscattered and reflected from a region 11 within the patient's body of the capillary bed 5 to detector 8. In the latter case, an alternating electric current is caused to flow between electrodes 14, 15 along a conduction path 16 confined substantially to the depth D of the capillary bed 5 and the voltage drop between these electrodes, or preferably between electrodes 18, 19 is measured. <IMAGE>

Patent GB-2034334-A (GB)
Title: Process for preparing emulsions of copolymers containing N- methylol or N-methylol ether groups
IPC: C08F246/00
Filed: 1979-10-16
Abstract: The process has two steps, the first consisting of polymerizing a portion of the monomer reactants in the presence of a per acid salt initiator, and at a temperature not above 60 DEG C if the N-methylol (ether) monomer is present, and the second of continuing the polymerization with the addition of the remaining monomer reactants at a temperature not above 60 DEG C and at a pH in the range of from 1 to 7, and in the presence of a redox initiator system. The process improvement resides in reducing the amount of unwanted premature condensation of the N-methylol (ether) groups during polymerization. The copolymer emulsions thereby provide thermosetting coating compositions having improved properties.

Patent GB-2037570-A (GB)
Title: Releasable and adjustable end attachment for watchband and the like
IPC: A44C5/14
Filed: 1979-11-06
Abstract: Disclosed is a watch band end attachment adapted to be releasably and adjustably mounted between the spaced lugs of a watch. The end attachment of the invention typically includes a housing, one end of which fits between the spaced lugs and the other end of which is connected to the watch band, and levers on opposite sides of the housing with a sliding member therebetween. The levers have lug-engaging ends disposed in the first end portion of the housing and pivot ends in the second end portion. Cam surfaces of the levers coact with cam-engaging surfaces of the sliding member as the latter is translated from the pivotal ends toward the lug-engaging ends of the levers to cause the lug-engaging ends to pivot and extend through the side apertures in the housing and engage the lugs of the watch. Reverse movement of the sliding member disengages the end attachment from the watch. Accidental disengagement is prevented by locking means typically in the form of a spring associated with the levers or sliding member. Attachment and detachment is accomplished by simple manipulation of a finger tab connected to the sliding member and accessible from outside the housing.

Title: Apparatus for Supplying a Fluid Additive to a Dish Washer
IPC: A47L/
Filed: 1979-11-29
Abstract: Pressurized water is fed to the driving cylinder 1 alternately through inlets 16, 17 in the end walls 5 and 6, causing reciprocation of both pistons 2, 4. Detergent or other additive is thereby sequentially drawn into cylinder 3 through valved inlet 18, forced through the valved bore 20 in piston 4, and expelled from cylinder 3 through valved outlet 19 in end-wall 7. It can then optionally be mixed with water from cylinder 1. Low-friction seals are provided by O-rings 2', 4', 15. For ease of maintenance and adjustment the cylinders 1, 3 are detachably and sealingly seated in annular grooves (10-13) in the end walls 5, 6, 7. The driven cylinder 3 is of smaller diameter than cylinder 1, thus giving a high pressure to the detergent. The output volume is adjustable via screw 43. <IMAGE>

Title: Control arrangements for producing linear motions
IPC: B63H21/22
Filed: 1981-04-21
Abstract: Hydraulic control arrangements for operation from the bridge of a ship are disclosed. In each example, a cam 19 can be displaced linearly. by a cable 20 from the bridge to control a valve 9 via a lever 21. In response to displacement of the cam 19, the valve 9 causes oil to be fed to a cylinder 6 so that the latter is displaced, thereby displacing a carriage 2 until the lever 21 adopts a position with its roller 22 approximately mid-way along the camming surface 23, whereupon the valve 9 stops the flow of oil and the carriage 2 stops. In one example, a cam (34), Figure 2 (not shown), is carried by the carriage 2 for displacing a lever (35) as a result of movement of the carriage 2, the lever (35) being connected to control the speed of an engine of the ship via a cable (38); and another lever 25 carried by the carriage 2 is connected to the pitch setting mechanism of a controllable pitch propeller via a cable 30 for altering the pitch of a controllable pitch propeller of the ship as a result of displacement of the carriage 2. In another example (Figure 3, not shown), instead of the other lever 25 for controlling the setting of a controllable pitch propeller, there is another lever (41) pivotally mounted and displaced as a result of movement of the carriage 2 by cams (39 and 40) carried by the carriage 2, the other lever (41) being connected to control a reversible gearbox for the engine via a cable (49). In each example, the carriage moves at a given speed lower than that of displacement of the cam (19) irrespective of the speed of the displacement of the cam if the latter is greater than the given speed. The pivot point (36) of the speed control lever (Figure 2) may comprise an eccentrically mounted bush (54, Figures 5 and 6, not shown) whereby the bush may be moved (eg by piston 63) to increase the range of movement of lever (36). <IMAGE>

Title: Radar drill guidance system
IPC: G01S13/88
Filed: 1981-06-16
Abstract: A short pulse radar drill guidance system comprises a radar tool 10 for insertion in an earth borehole in a process for mapping various geological discontinuities within the earth. The system has particular application in the mapping of shale surrounded coal seams. The tool 10 comprises a casing 16 housing a source 30 of electro-magnetic pulses, a transmitting means 12 connected to that source, receiving means 14, directive antenna means 26, 36 for the transmitting and receiving means and control circuit means 20 for controlling both the transmission of pulses and the reception of reflections thereof. The specific configuration of these components within the tool casing 16 is designed to minimise the effects of electromagnetic coupling between transmitting and receiving antennas 26 and 36 and thus misleading readings consequent thereon. Control means 20 is battery powered and is capable of performing all necessary control of receiving and transmitting functions thereby eliminating both the need for down bore control signal communication and the length control wires associated therewith. This in turn facilitates impedance matching between the receiving means and antenna and minimizes errors due to mismatching which may otherwise occur. <IMAGE>
