Patent GB-720659-A (GB)
Abstract: 720,659. Seats. LEWINBERG, H. W. Feb. 3, 1953 [Sept. 25, 1952], No. 3017/53. Class 52 (2). A chair of the kind which is convertible for use as an easy chair or as a dining- room chair and comprising side frames interconnected by transverse members and a combined seat and back unit arranged for tilting between the side frames on a fixed horizontal axis is characterized in that the abutment on the frame upon which the seat rests when in easy.chair position is lower than that upon which the seat rests when in dining-room position. The tilting pivot 10 passes through the side frames and through one member, say 8, of the seat and back unit at a position displaced from the junction 12 of the members of the unit. In position as an easy chair the member 9 rests on the cross member 6 of the frame 1 and constitutes the seat and the member 8 forms the back rest. In the dining-room chair position the member 8 rests on the cross member 7 and forms the seat, the member 9 forming the back rest. The seat in the dining- room chair position is situated in a more elevated position than that in the easy-chair position. Locking arrangements may be provided for use in the dining-room chair position.
Patent GB-745326-A (GB)
Abstract: 745,326. Kitchen ranges. ALLIED IRONFOUNDERS, Ltd. June 30, 1954 [Dec. 8, 1953], No. 34106/53. Class 126. In a cooking stove of the kind having a hopper-fed solid fuel fire-box and an oven extending laterally from one or both sides of the hopper, the top of the oven is heated by combustion gases traversing flue passages, the side nearest the firebox is heated by conduction from the firebox structure, and heat conducting and reflecting elements are arranged to transmit heat to the side of the oven remote from the firebox and to the bottom of the oven, so that the oven is heated to substantially the same temperature all over. An oscillatable grate 7 mounted in a combined firebox and ash pit 1 is fed with fuel from a superposed hopper 2 lined with refractory material 13 which is thickest at the middle part of its height. Ovens 4 at either side of the hopper are heated by the passage of combustion gases through top flues 14, and by conduction through the wall adjacent the hopper and a member 11, supported on an extension 12 of the bottom of the oven and extending obliquely away from the oven to or into the firebox. Further heat is supplied to the bottom of the oven from a reflector box beneath the oven with side walls 19 and bottom wall 18 which may extend below the ash pit. The wall 21 of the oven remote from the firebox is heated by conduction from a downward extension which receives radiated heat from the firebox and ashpit. The downward extension may be integral with the oven wall and from the end wall 22 of the reflector box. In a cooking stove with two ovens, the flow of gases through the top flue of one oven may be controlled by a damper. Specifications 408,541 and 666,809 are referred to.

Title: Actuation cap assemblies for dispensing containers
IPC: B65D83/14
Filed: 1978-10-13
Abstract: An actuator fitted to the valve of an aerosol dispensing can cooperates with an actuator-orientator assembly to orient the discharge orifice of the actuator into the proper position to spray a stripe of marking material. The actuator 15 has a generally cylindrical outer surface 16 and is adapted to be mounted on the valve stem 12 of an aerosol can 10 and includes a spraying orifice 18 and a pair of radially outwardly extending locating lugs 20. The actuator-orientator 24 is provided with a circular central opening 24 into which the actuator is inserted, and a pair of recesses 27 which extend radially outwardly from the central opening for receiving the locating lugs 20 of the actuator when the actuator is properly oriented. One end of the central opening is defined by curved guide surfaces 26 which extend upwardly from the recesses 27. A guide surface 26 extends from each side of each recess 27 and meets a guide surface 26 from the other recess 27 at the midpoint 31 of the arc which extends between the recesses. When the actuator is inserted downwardly into the opening 28 of the orientator and the lugs 20 engage the guide surfaces 26, the actuator and aerosol can move downwardly and rotate along the guide surfaces until the lugs 20 are seated within the recesses 27. <IMAGE>

Title: A liquid supply control system
IPC: A01G25/16
Filed: 1978-10-17
Abstract: An automatic watering system uses the water supply itself to energise the operation of a control valve (4). The valve has a main outlet (3) and a secondary outlet (9) which slowly feeds into a first compartment (7) carried by a pivotally suspended valve actuating member (5) biassed towards the opening position by a counter-weight (10). This secondary outlet water feeds from the first to a second compartment (8), which eventually overcomes the bias and closes the valve. The first compartment (7) drains and by drip and evaporation through a wick (11) the second compartment slowly empties. Eventually the bias restores the valve to open and the cycle repeats. <IMAGE>

Patent GB-2014106-A (GB)
Title: A device for shrink-wrapping articles
IPC: B65B53/06
Filed: 1979-02-02
Abstract: In a device for shrink-wrapping articles, hot air is blown towards the article (4) covered in shrinkable RIM (2) from a hot-air mast (15) which rotates about the latter. In the region of the centre of the sides of the article there is little or no support for the film (2) which can thus pull itself off the edge during shrinking without vertically securing the article. The device is thus arranged so as to provide for a variation in the intensity of the hot-air stream so that contraction in the troublesome regions can be reduced as necessary. This can be achieved by adjusting the temperature and/or speed of the blown air, and/or by varying the speed of rotation of the mast about the article and/or by providing baffles (19,20). Means are also provided for clamping the film so that it cannot contract in the relevant regions. <IMAGE>

Title: Apparatus for generating servo pressure signals for aircraft feel simulation
IPC: B64C13/46
Filed: 1979-12-04
Abstract: The apparatus comprises a diaphragm 26 acted upon by aircraft pitot and static pressures and coacting with a lever 22 which is normally biased into pivotal engagement with an abutment 21 by a spring 23. The lever 22 pivotally engages one end of a further lever 31 whose other end coacts with a valve 32 for regulating a servo pressure signal to a feel force actuator 13 for a pilot's lever 12. The servo pressure is applied to a chamber 42 of the valve 32 and biases levers 31, 22 against movement in response to an increase in the difference between pitot and static pressure. At a predetermined value of q, set by a cam 24 which is responsive to a trim position D of an aircraft control surface, the spring 23 compresses, and movement of the valve 23 in response to q ceases. A bellows 50 acts via lever 51 on the lever 31, and is subject to static pressure externally to provide an altitude-dependent input. <IMAGE>

Patent GB-2061654-A (GB)
Title: Improvements in and relating to frequency discriminating circuits
IPC: H03L7/087
Filed: 1980-10-14
Abstract: An input signal is mixed in a first mixer (12) with a reference signal and in a second mixer (14) with the reference signal displaced by 90 DEG , to produce, at two points (I, II), signals having slopes dependent on the frequency difference. Two gates (30, 36) respectively compare limited versions of the signal at one point (thus representing the sign of the signal at said point) with a signal dependent on the slope of the signal at the other point. Each gate (30, 36) produces a digital output whose level is dependent on the difference in frequency between the input signal and the reference signal - the two inputs to each gate changing state at the same time. In order to eliminate errors, such as due to circuit delays or noise, which might occur if the two signals to each gate do not change state at exactly the same time, a switching circuit (54) selects one or other of the gate outputs in dependence on the relative magnitudes of the signals at points I and II - so that neither gate output is selected when its inputs are undergoing transitions. An output is produced on line 58 having a sign dependent on the sign of the frequency difference. Analogue outputs are produced on lines 71 and 72 which are dependent on the magnitude of the frequency difference between the input and reference signals. The signal on line 71 is independent of the sign of the frequency difference. The signal on line 72 has a sign dependent on the sign of the frequency difference. <IMAGE>
