Title: Direct Mono-Esterification of Aryl Malonic Acids
IPC: C07C69/612

Patent GB-624408-A (GB)
Abstract: 624,408. Gyroscopic apparatus. SPERRY GYROSCOPE CO., Inc. Sept. 25, 1944, No. 18276. Convention date, May 10, 1943. [Class 97 (iii)] [Also in Groups XXXV and XXXVIII] The disturbance of the sensitive element of a gyroscopic instrument by, e.g. frictional forces between the element casing and its support, is corrected electrically. As shown, Fig. 1, the gyro rotor casing 36, of a direction gyro, is mounted in the vertical ring 33 movable about the vertical axis relative to the casing 38 fixed to the craft. Slight friction forces at the vertical axis bearings cause, (a) the vertical ring to tend to follow the craft as the latter alters course, and (b) the rotor casing 36 to tilt about the horizontal axis. The latter movement causes relative displacement of the members 16, 19 of a signal generator, the output of which is applied to the torque motor 39 to effect a restoring motion opposite to that due to the friction forces. In Fig. 6 (not shown), the invention is applied to a gyro vertical to stabilize the latter against friction forces at the bearings.

Title: Endless Track Wheels
IPC: B62D55/14
Filed: 1979-05-03
Abstract: A method of providing an endless track wheel with wear resistant steel rings (4), comprises shrinking the rings (4) on to side walls (3) of the rims. The rings (4) are constructed angularly in such a manner that one limb extends axially and the other limb approximately parallel to the adjacent surface of chain guide teeth. Each axially extending limb is so shrunk on that the degree of shrinkage, thus the difference between the clear diameter (D4) of a radially inwardly facing surface (4.1) formed by the axially extending limb and the diameter (D3) an outer shoulder (3.1) referred to the mean diameter of the rim is between 0.03% and 0.2%, while the diameter (d3) of an inner shoulder (3.2) is not greater than the clear diameter (d4) of a radially inwardly facing surface (4.2) formed by the other limb of the ring (4). <IMAGE>
Patent GB-2053419-A (GB)
Title: Hydraulic Control Apparatus
IPC: F15B20/00
Filed: 1979-07-06
Abstract: A hydraulic control system (10) connects pump and tank input lines (30, 32) to output lines (C1,C2) which are connected to an actuator (12) which incorporates a rolling diaphragm (18). An electrically controlled servo valve (20) selectively connects the input and output lines. A safety unit (40) is incorporated into the system so that in the event of failure of either the hydraulic pressure or the electrical supply, the output ports (C1, C2) are coupled) together to avoid damage to the actuator. To this end a solenoid valve (50) when energised connects the pump to one end of a spool valve (42) to move it against the force of a spring (48). If either the solenoid is de-energised or the hydraulic pressure fails, then the spring (48) returns the spool (44) to a position where the output ports (C1, C2) are connected together and also the input ports (P, T) are connected together. <IMAGE>

Title: A diaphragm valve
IPC: F16K7/12
Filed: 1979-09-11
Abstract: A diaphragm valve has a diaphragm support 5 disposed between a diaphragm 3, and a pressure member 4 connected with the diaphragm and by means of which the diaphragm 3, which is clamped at its edge between a valve housing 1 and a head 2 in which the pressure member 4 is accommodated, can be moved into and out of engagement with a valve seat in the valve housing by axial movement of the pressure member 4 in the valve hood. The valve hood has radially inwardly extending longitudinal ribs 6 which extend into corresponding radial slots in the pressure member 4 to guide member 4 in axial movement, the end faces of the ribs facing the diaphragm being arranged to engage the diaphragm support in the open condition of the valve and the member 4 engaging the diaphragm support 5 in the closed condition of the valve. The diaphragm support 5 is in the form of a resilient spiral member, instead of the plurality of discrete concentric rings used in known valves, and can thus be manufactured readily and cheaply as compared with known constructions requiring accurate machining. <IMAGE>

Title: Method and circuit for controlling switching on a heating or air- conditioning installation
IPC: G05D23/24
Filed: 1980-01-18
Abstract: A control circuit for switching on heating or air-conditioning apparatus comprises a computer (10) which is supplied with a signal (U1) depending on the difference between a desired value Xk and actual room temperature tr a signal (U2) depending on measured outside temperature ta and possibly a supplementary signal (U3). The signal (U3) serves for an additional advance of the moment of switching on after a switched off period of more than 24 hours and is added to the signal (U1) in an addition network (12). Also supplied to the computer (10) are signal S+, S- from two control elements (14, 16). At these two control elements (14, 16), a heating-up gradient S (Figures 2 and 3) is set up and is adapted to characteristics of the heating apparatus and building. The resulting output signal U4 from the computer 10 is compared in a comparator 36 with a rising ramp voltage U5 derived by a D/A converter from timing pulses. As soon as U5 reaches U4 the heating apparatus is switched ON at maximum output precisely at moment 74 (Figure 3). <IMAGE>

Title: Monitoring lift systems
IPC: B66B5/02
Filed: 1980-03-25
Abstract: A lift system comprises a lift car 7 in a lift shaft 8 and electrically connected to a control panel 5 and a monitor panel 3 arranged to provide an alarm output signal on cable 2 when activated by the lift car ON/OFF alarm switch depending upon the condition of a continuity circuit (Fig. 5) (not shown). The continuity circuit is formed by sensors respective to the condition of the lift car door 11, the landing door 14 and the level A, B, etc. at which the car 7 is located. The lift car door condition is monitored by sensor arrangement 12, 13, the landing door condition by sensor arrangement 15, 16, and the car level by sensor arrangement 9, 10. When the alarm switch is moved to its ON position by a lift car passenger and the continuity circuit indicates a safe exit condition for the lift car 7 panel 3 initiates in panel 5 a signal to move the lift car 7 to a predetermined floor level (e.g. ground level) and the monitor panel self resets thereafter if the continuity circuit continues to indicate a safe exit condition but in the converse situation issues an alarm signal. <IMAGE>

Title: Production codes on articles
IPC: B07C5/34
Filed: 1980-05-22
Abstract: A glass container having moulded on the base thereof, incorporated in the base stippling (2), a production code indicative of the mould cavity number. The code is in n binary bits constituted by a series of n sequential groups, each group relating to a different bit in the code, each group containing two marks having no significance to the value of the group bit and either a further mark substantially equally spaced from the two marks or a gap, depending on the value of the group bit (1 or 0 respectively). As illustrated in Figure 1, reading clockwise, the first and last 5 marks are ordinary stipple marks. Ignoring these and reading 0 for a gap, 1 for a mark gives:     (010)11(0)11(1)11(0)11(1)11(1)11(0)11(0). (010) is a start read flag and the 7-bit code, from the values in the other parentheses, is 0101100 (least significant bit to the left). This equals mould cavity 26. <IMAGE>
