Patent GB-2075674-A (GB)
Title: Method and apparatus for the calorimetric study of composite materials
IPC: G01N25/48
Filed: 1980-03-25
Abstract: A composite material (e.g. a crystalline metal, alloy, organic or inorganic) and a reference sample are incrementally heated in a DTA device (1). A signal indicating the temperature difference between the reference sample and the composite material is converted into to the total heat flux for the transformation process by means of a converter (3) and from this flux and heat flux absorbed or lost by the inert component of the composite material is obtained and compared. A subroutine (5) gives the difference between the total flux and the flux of the inert component; a chronometer (8) measures the time periods from the moment of application of heat to the moments corresponding to the maxima of the absolute values of the total flux, and the flux of the transformation component; two subroutines (6, 7) integrate the total flux and that of the transformation component, against their respective baselines; and a data recorder (9) records the temperatures before and after increments, the total flux, the flux of the transforming component, the time periods, the integrated values of these two fluxes and the calibrated value of the inert component. <IMAGE>

Patent GB-2075725-A (GB)
Title: Electronic timepiece movement
IPC: G04G21/00
Filed: 1981-04-08
Abstract: An electronic timepiece movement includes a control stem slidably guided in a radial passage of a base plate. Pulling on this control stem brings a return spring acting on the stem into contact with a stud which is carried by the substrate of an electronic circuit module of the movement. This connects a conductive lead to ground, which controls an operation function of the timepiece. The pull-out control stem and associated return spring can be replaced by a push-in member and by a return coil spring located in said passage. The stud is then positioned in a hole of the substrate of the electronic circuit, which hole is situated opposite to the longitudinal axis of the passage. Pressure exerted on this push-in member places a portion thereof into electrical contact with the stud and this connects the lead to ground, as before. Thus, the movement can according to choice be completed for operation either by a push-in control movement or by a pull-out control stem movement.
Patent GB-2098419-A (GB)
Title: Electrical frequency adjusting arrangements
IPC: H03L7/185
Filed: 1981-05-07
Abstract: A circuit arrangement for producing an output Fo is in the form of two phase-locked loops 5 and 6 fed with a common reference frequency Fr. In order to provide very fast lock- up, Fr is high, 2.5 MHz say. The use of the two loops, interconnected via divider 24 and mixer 10, enables Fo to be adjusted in relatively small steps in spite of the high value of Fr. Mixer 10 is in the form of a quadrature demodulator (Fig. 2) and is therefore able to select the lower sideband output without the need for a filter, thus avoiding the problems which would be caused, if such a filter were used, by the closeness of the two sidebands at the frequency used. <IMAGE>

Title: Process for producing heating foils as a heating system for buildings.
IPC: H05B3/10
Filed: 1981-09-23
Abstract: The invention relates to a process for producing heating foils as a heating system for buildings using a heating foil comprising a current path-like heating conductor with a clearly defined resistivity value per length concealed between two polyethylene and polyester foils. ((30b, 31b) and (30a, 31a) respectively). According to the present process, a rolled sheet blank is cast from which the foil is subsequently rolled and in which, in at least one heating conductor path (120), is simultaneously formed a cavity with a depth of 10 to 100% of the total thickness and which in a second process is filled with a tin-lead- antimony alloy or a low melting point lead-bismuth alloy, forming the layer designated (20). This simplifies the production of such heating foils and therefore is more economic, whilst retaining the safety feature that the heating conductor path will be broken before a dangerously high temperature could develop. <IMAGE>

Patent GB-2141685-A (GB)
Title: Bag-forming machine
Inventor: ROWELL FRANK JOHN
IPC: B65B9/14
Filed: 1983-04-13
Abstract: In a bag-forming machine, a flexible tube (12) is advanced and transversely sealed by bars (11). Spreaders (4) are used to engage opposite inner surfaces of the tube (12) and spread and flatten the tube (12) prior to sealing, thus avoiding puckers. The bag can be filled while the spreaders (4) are still within the bag. In order to avoid difficulties caused by friction between the tube (12) and the spreaders (4), and also to allow the bag to assume a more roundish shape for filling, the spreaders (4) are retractable and openable pneumatically, the stroke of the pneumatic ram being limited so that when open, the spreaders (4) assume a fixed, predetermined position. The retraction and opening of the spreaders (4) is cyclical, the spreaders (4) being retracted while the tube (12) is advanced and being open while the tube (12) is stationary. <IMAGE>

Title: Apparatus for helping a person get in or out of a bath
Inventor: PENNINGTON-RICHARDS CYRIL MONT
IPC: A61G7/10
Filed: 1983-05-27
Abstract: Apparatus for helping a person to get in or out of a bath comprises a seat mounted at the lower end of a carrier (10) which is suspended at its upper end (11) from the upper end of the push rod (6) of a hydraulic jack having its cylinder (5) fixed vertically in position adjacent the end of the bath (1). The push rod (6) is extended to lift the carrier by supplying mains water to the cylinder (5) under the control of a valve (20), the push rod being guided vertically and restrained laterally by a pair of fixed vertical guide channels. When the push rod (6) is fully extended the carrier (10) hangs from a cross bar (7) with wheels (12) mounted at the back of the carrier at its lower end resting against and retained by an anchor plate (13) fixed above the bath. When the cylinder (5) is exhausted, the push rod (6) retracts, the seat (9) is lowered into the bath, and the wheels (12) run off the plate (13) and down the inside (17) of the bath until the seat (9) reaches the bottom. Any change in inclination of the carrier (10) caused by the wheels following the contour (17) of the bath is accommodated by the upper end (11) pivoting about the horizontal axis of the cross bar (7). In a second example the carrier (10) is also rotatable about the vertical axis of the lifting jack (5,6) when the seat (9) is fully raised. <IMAGE>
