Patent GB-565343-A (GB)
Title: Improvements relating to the production of cellular materials from cellulose derivatives
IPC: C08J9/00
Filed: 1942-12-14
Abstract: Cellular material of a cellulose ester or ether is obtained by forming from the cellulose derivative a gel containing a true solvent for the ester or ether, replacing the solvent by a non-solvent organic liquid which is miscible with the solvent, and then effecting evaporation of the non-solvent at a temperature sufficiently low to avoid collapse of the gel structure.  The gel may be made by the addition of non-solvent to a solution of the cellulose ester or ether in a solvent which is miscible with the non-solvent.  A solution comprising 10 parts of cellulose acetate, 13 parts of ethanol, 13 parts of benzene and 50 parts of acetone is formed into a coherent gel by slowly adding benzene.  The gel is lightly pressed between cheese cloth into the form of a slab and immersed in benzene for 1 day, the benzene being renewed several times.  The gel is then removed from the bath and allowed to dry.  The product is a rigid tough slab of cellular material. The gel may be shaped or moulded before washing.  The dried material may be sawn or planed.  The non-solvent should be sufficiently volatile to be removed by evaporation at ordinary or slightly raised temperature.  The non-solvent used for soaking the initial gel may be different from that contained in the solution from which the gel is formed.  Thus, the gel may be formed from a solution containing acetone, ethanol and benzene, and it may be soaked in water.  Another method of forming the gel is to dissolve the cellulose ester or ether in a mixture of solvent and non-solvent in which the ester or ether is only soluble at elevated temperatures and then to cool the solution.  For cellulose acetate such a liquid mixture may consist of acetone and benzene or alcohol.  The gels may contain plasticisers, particularly those of the solvent type.  Cellulose esters may be subjected to saponification when in the cellular form.  Organic or inorganic bases may be used in aqueous or alcoholic solution or in gaseous form to effect saponification.  The cellular material may be used as heat- or sound-insulating material for buildings or refrigerators.  It may be used in making floats, pontoons, rafts and lifeboats, or sealing-rings, gaskets and washers, or in making bearing surfaces or structural components and it may be reinforced with steel strips.  It may be impregnated with liquids, e.g. oils, glycerine, glycols and other sealing liquids.  The pores on the surface of the material may be sealed by applying an oil, resin, or cellulose derivative lacquer, or preformed films may be applied.  The surface of the cellular material may be metallized. Specification 561,240 is referred to.

Title: Combined signal selection and level adjustment control
IPC: H03J3/08
Filed: 1973-04-04
Abstract: 1364325 Signal selection and gain control RANK ORGANISATION Ltd 4 April 1973 [18 April 1972] 17818/72 Headings H3Q and H3T [Also in Division G1] In an arrangement for combined signal selection and level adjustment, operation of a single actuator, 8, Fig. 1, is arranged to both select a signal and bring an adjustable level control for the signal to an initial setting and the setting of the level control is thereafter automatically adjusted until the actuator is released. As shown in Fig. 1 pressing a pushbutton 8 effects station or channel selection which selection is retained by a latch 7. Also as the button is pressed in a pawl 4 moves out of engagement with a ratchet wheel 1 so as to enable a spring 3 to rotate the ratchet wheel 1 in an anticlockwise direction. This reduces to a lower zero level the volume of a signal level or volume control (not shown) connected to a spindle 2 which is fixed to the ratchet wheel 1. On fully pressing the button contacts 11 are closed to energize a motor 5 which drives the ratchet wheel 1 in a clockwise direction via a slipping clutch 6. This causes increased volume and when desired the button 8 is released to the position determined by the latch 7 so as to stop the motor 5 and return the pawl 4 into engagement with the ratchet wheel so as to retain this volume setting. In the embodiment of Fig. 2 on operating a push button or touch button for station selection a capacitor 14 is discharged. FET 12 then operates to reduce the gain of an audio amplifier in the sound channel to zero or a low level. Then switch 15 is closed to charge the capacitor 14 until the desired volume is reached where on releasing the button the switch 15 is opened and the volume is maintained by the charge retained on the capacitor 14. The control arrangement may be used in radio, television or audio equipment. The Specification mentions application to remote control.

Bogies.-A rail vehicle having track-brake gear mounted upon a two-wheel truck or bogie with track-brake shoes on one side of the wheels only, the gear is adapted to apply a pa.rt or the whole of the reaction of the track shoes to the vehicle body. The body of the vehicle is mounted by means of rollers on pillars 3 sliding vertically in the truck 1 and spring-supported on boxes 5 which house the ends of semi-elliptical springs bearing on the truck at 6. The brake is applied by means of a link 11 and a balance lever 12 connected to two bell-crank levers 13, 14 mounted on a common pivot 15 on the truck. The lever 13 bears on the track shoe 16 and lever 14 is linked through a lost motion device to a tailpiece on the box 5 and thus bears on the vehicle body. The link 11 is operable either by an air cylinder 7, a crank 8 and rock-shaft 18, or by hand through a pull-rod 9, a lever 10 and the shaft 18. Stops 20 limit the lift of the pillars 3. In a modification the brake pull-rod acts through a toggle on the track shoe on the one hand and on the other hand upon a lever pivoted on the truck and connected at its other end to a pillar through which pressure may be applied to the vehicle body. A radius rod connected to the truck takes the drag of the brake shoe. The track-brake shoes may also be constructed as magnets with a winding to take current from the main supply or the regenerative action of the motors.

Both calling and called subscriber have the RON and TRON wires at their respective equipments and at their respective line circuits, and these latter two pairs of wires are switched through the exchange, along with the two-wire line L1, L2 in the conventional manner. The sequence of operations for setting-up a call, AB2 being the called party, once switchthrough has been completed, is as follows: (a) The calling party, via the signalling device at his equipment, applies a positive potential to the exchange TRON wire which energizes relay I directly, and relay R via the line L1, L2 and transformer circuit T2. Contact r thereby closes to provide a calling signal. (b) The called party acknowledges by depressing key E. Relay PR is energized, resulting in the energization of feed relay A at the line circuit. Thus contact α closes and sends a "connection made" signal to the calling party. (c) The calling party cancels the positive potential at TRON exchange, causing r to open and the calling signal to cease. (d) The called party releases the key E which causes the release of PR and consequently A, thereby removing D.C. from the line.
