Title: Improvements in devices for controlling the temperatures of apparatus for heating, cooking, baking, or the like
IPC: G05D23/19
Filed: 1942-01-29
Abstract: 555,012. Valves. RYLE, T., and MURPHY, J. Jan. 29, 1942, No. 1248. [Class 135] [Also in Group XXXVII] In a device for controlling the heating of cooking apparatus &c. by periodically operating a switch or valve the ratio of " make " to " break " is automatically varied by the step-by-step movement of a timmg device. As shown in Fig. 1, a clockwork or elecric motor drives a cam A which periodically oscillates a mercury switch P by means of a push rod N. The cam A also drives a ratchet wheel D by a pawl I and intermediate mechanism E, G and a cam C fixed to the wheel D is thus caused to move step by step and raise or lower a rod N<SP>1</SP> which alters the fulcrum of the mercury switch P and so varies the ratio of make to break. The device may be arranged to slowly increase the heating up to a maximum at which it remains constant, the mercury switch remaining permanently "on" in spite of its oscillation or it may cause a decrease of heating. An adjustment Kk varies the numbers of teeth so that the wheel D moves forward at each actuation, and the wheel D may have teeth over only part of its periphery so that it stops when the pawl engages the smooth part or the teeth may extend all the way round and an adjustable shield be provided to cover some of the teeth and achieve the same object. In a modification, Fig. 9, the cams A, C depress rods V, V<SP>1</SP> into a bath of mercury so that a circuit between contacts x, y is periodically interrupted. In another modification, the step-by-step cam C supports a mercury vessel into which dips a contact oscillated by the cam A.

Title: Improvements in change speed gears for cycles, motor cycles and the like
IPC: B62M9/1242
Filed: 1939-01-16
Abstract: 520,663. Change - speed chain - gearing. VAGNIEZ & MARMIN, A. Jan. 16, 1939, No. 1447. Convention date, Jan. 17, 1938. [Class 80 (ii)] [Also in Group XXXI] The invention relates to change-speed gearing, for cycles and motor-cycles, of the kind in which a chain 21 is shifted laterally on to different sized driven sprockets 33 by means of a shiftsprocket 20, mounted on a shiftable carrier 22 on which is pivoted a lever 34 carrying a tensionsprocket 35, a single spring 37 being provided for positively urging the carrier 22 in one direction, viz., towards the low-speed position against the pull of the Bowden control-cable 1, and also for urging the lever in the chain-tensioning direction. According to the invention the single spring 37 is connected between a fixed part 38 and the end 36 of the tensioning-lever 34, which end 36, during a shift, moves about the shift-sprocket carrier 22 in a direction which coincides with that of a component of movement which is imparted to the said carrier 22, whereby the spring length and hence the chaintension remain substantially constant in all operative positions. The carrier 22 is secured to a member 23 which constitutes one side of a deformable parallelogram, the opposite side 24 of which is adjustably fixed to the cycle-frame, and is connected to the movable side 23 by two pivoted sides 25. 26. Lateral movement of the shift- and tension - sprocket carrier 22, 23, to change speed, is produced. by deforming the parallelogram by swinging the pivoted sides 25, 26 under the control of the Bowden cable 1 acting against the spring 37. Such deformation results in the carrier 22, 23 having a longitudinal component of movement in addition to its transverse chain-shifting movement, and this longitudinal component compensates for the relative movement of the chain-tensioning lever 34 about the carrier 22, 23 as the chain engages a different driven sprocket 33, whereby the length of the spring 37 and hence the chaintension is kept substantially constant in all operative positions.

Filed: 1921-01-10
Abstract: 157,960. Mulligan, P. C. Jan. 26, 1918, [Convention date]. Generating by direct contact of combustion products; feed-water, supplying and controlling.- Combustible gases are compressed by pumps delivered to a reservoir and pass to a combustion chamber 3 when the pressure therein permits the compressed gases to open the valves 30. Water from a jacket surrounding the chamber 3 passes down a pipe extending through the chamber and emerges through perforations 41 when a valve 6 is lifted by mechanism, driven by the motor. The pipe is secured at one end to an external support 7 and its lengthwise expansion due to the temperature obtaining in the chamber 3 determines the timing and lift of the valve 6. The corresponding admission of water serves to maintain a constant temperature in chamber 3. The combustion products pass to a reservoir 5 from which the motor receives a continuous supply. An extra outlet 47 is controlled. by a valve 46 operated from the motor and connects the chamber 3 directly with a low-pressure stage of the motor. The reduction in pressure occasioned by the opening of the valve 46 enables the combustion gases to enter the combustion chamber. The charge is ignited by means of a sparking-plug 31. The apparatus is shown applied to a turbine driving a main shaft through toothed gearing.

[Class 40 (iv).] In a voice-frequency signalling system for use, for example, in the system described in Specification 381,597 the level of a preliminary signal controls the adjustment of the attenuation of a circuit through which the signals are received so that subsequent signals will have a predetermined level. The equipment shown is associated by a finder switch with a register controller and a relay LR (not shown) energizes CR which energizes CU to cut a 6 db. resistance into the circuit of the V.F. relays VA .. VC, VD remaining connected to the line side of the resistance. The preliminary signal energizes VA, VB, VD, releasing CR and energizing CS to hold CU. CR on falling initiates the sluggish operation in turn of CA .. CD to cut the remaining 3 db. resistances into the transmission circuit in turn. When sufficient resistance has been cut in to release either of the relays VA, VB, CR is again energized to prevent operation of further relays of the series CA .. CD, those operated however remaining locked up. At the end of the signal, CS is released and during the release time of CU, CT pulls up, locks and connects VD to the relay side of the resistances.

Patent GB-653055-A (GB)
Title: Stabilisers for cellulose derivatives
IPC: C08K5/46
Filed: 1948-01-21
Abstract: Stabilizers for cellulose esters or ethers are prepared by reacting a glycol having at least three carbon atoms with thionyl chloride. Ethylene glycol sulphite described in Specification 346,685 may also be used as a stabilizer.  Suitable alcohols which may be used in the preparation of the stabilizers are diethylene glycol, triethylene glycol, 1,2-propylene glycol, di-propylene glycol, 2-ethyl hexanediol-1-3, 2-methyl hexanediol-2,4, 2,3-butane diol, diglycerol, 1,3-butanediol, 1,4-butanediol, octamethylene glycol, decamethylene glycol.  Hydrogen chloride formed during the preparation of the sulphites may be bound with pyridine or withdrawn from the reaction zone by a stream of air or inert gas or by evacuation.  The sulphites may be cyclic (see Group IV (b)) or linear polymers.  The stabilizing agents may be mixed with ethyl cellulose in flake form, or may be dissolved or suspended in plasticizers or mixed with volatile solvents for the ethyl cellulose.; or they may be incorporated on hot rolls or in suitable mixers.  Colouring matters may also be added. In example (1) ethyl cellulose flake, dibutyl phthalate and a long chain polymer prepared from diethylene glycol and thionyl chloride are mixed together; (2) ethyl cellulose, partially hydrogenated isomeric terphenyl, mineral oil, poly-diethylene glycol sulphite and cadmium selenide red are mixed on hot converting rolls, to a sheet which is cooled and ground to a moulding powder; (3) ethyl cellulose is mixed with dibutyl phthalate and 1,2-propylene glycol sulphite; (4) ethyl cellulose is mixed with dibutyl phthalate and ethylene glycol sulphite; (5) a polymeric sulphite is prepared from thionyl chloride and 1,4-butanediol.  It is stated that 1,3-butane diol, 1,10-decanediol, dipropylene glycol or triethylene glycol could replace the 1,4-butanediol.  Examples (6) and (7) describes the production of stabilized moulded discs from ethyl cellulose, dibutyl phthalate and a variety of sulphites. Cellulose derivatives other than ethyl cellulose may be similarly stabilized.ALSO:Glycol sulphites which may be cyclic or linearly polymeric (see Group IV (a)) are produced by reacting a glycol containing at least 3 carbon atoms and thionyl chloride.  Hydrogen chloride split out during the reaction may be fired with pyridine or removed from the reaction zone by a current of air or inert gas or by suction.  1.3-butanediol is stated to produce a mixture of cyclic and polymeric esters.  Cyclic sulphites may also be produced from 2,2 - butanediol, 1,2 - propanediol; 2 - methyl - 2, 4 - pentanediol; and 2 - ethyl - 1,3 - hexanediol.  An example describes the production of a cyclic ester from 1,2-propylene glycol and thionyl chloride at 25-30 DEG  C. After the reaction, hydrogen chloride is boiled off at low pressure, the mixture cooled and poured into sodium carbonate, and the oily layer separated and distilled.  Another example describes the production of ethylene glycol sulphite but this is not claimed. Specification 346,685 is referred to.
