Title: Dual compartment tire
IPC: B60C5/20
Filed: 1956-10-05
Abstract: 801,994. Safety tyres. GOODYEAR TIRE & RUBBER CO. Oct. 5, 1956 [June 4, 1956], No. 30401/56. Class 144 (2). In a tubeless tyre 3 and wheel rim 1 assembly wherein a safety diaphragm 21 of substantially inextensible, or low stretch, material is sealed to the beads 4 of the tyre 3 to divide the air space into radially inner and outer chamber 13, 12, the diaphragm is sufficiently impervious to air to permit use of the tyre in the event of deflation of the outer chamber 12, Fig. 2, for a distance of at least 30 miles at a speed in the order of 30 m.p.h., means being provided for reducing friction between the opposed walls of the outer chamber when the latter is deflated. Inflation of the two chambers 13, 12 is effected through separate inflation valves 2, 10 fitted in the rim 1 and the tyre sidewall respectively. As shown the diaphragm is comprised of two superposed crossed rubberized plies 16, 17, Fig. 9, of parallel nylon cord of high stretch from which most of the stretch has been removed, the cords of the plies subtending an angle of 32 degrees with the circumferential centre line of the diaphragm and the edges 7 of the diaphragm being clamped, and possibly cemented, between the tyre beads 4 and the rim flange portions 5, 8 and terminating in beaded portions lying flush with the rim edges. The diaphragm encloses an inner chamber 13 of at least 60 per cent of the total air space of the tyre and may have a permissible stretch to increase this capacity, on deflation of the outer chamber, by 10 to 20 per cent, but insufficient to restore the normal height of the tyre. An inner lining 19 of butyl rubber renders the diaphragm substantially air-impervious, but if desired the diaphragm may be slightly porous so that topping-up inflation of the outer chamber may be effected via the valve 2 and diffusion through the diaphragm. Where substantially air-impervious, the inner chamber 13 may be inflated to a higher pressure than the separately inflated outer chamber. To reduce friction between the contacting surfaces of the diaphragm and tyre, Fig. 2, on deflation of chamber 12, either or both of the said surfaces are coated with a lubricant such as a silicone oil, silicone grease, paraffin, polyalkylene glycols or liquid polyesters prepared from dibasic carboxylic acids and glycols having an average molecular weight of approximately 1500. The valve 10, Figs. 4-6, comprises a rubber cylinder having an axial through slit 11, and domed end flanges 24, 23 which embrace the inner and outer surfaces respectively of the tyre wall after insertion, as by a rod 27 engaged in the initially blind slit 11, in an opening 9, in the tyre wall, which is approximately half the diameter of the valve body 22. The resultant compression of the valve body effectively closes the slit 11 but permits insertion of a hollow inflating needle 28 having a tapered end 29 and a lateral opening 30. In an alternative form the end 23 of the valve is frusto-conical to engage in a countersunk recess in the tyre wall.

Abstract: 1400363 Digital transmission; error detection and correction HONEYWELL INFORMATION SYSTEMS Inc 26 June 1973 [26 June 1972] 30413/73 Heading H4P An arrangement for error detection/correction comprises a cyclic redundancy register accumulator divided into low and high order positions with a first mod-2 adder 42 receiving selected data bytes and data from one of the positions, the sum causing selected retrieval of modifier signals stored in a "look up" memory, and a second mod-2 adder 48 responsive to bits in the other position and modifier signals, updated cyclic redundancy accumulation being fed back to the register. Input data is fed through buffer register 14 and gate (18) to line register 16, and also through gate 22 to mod-2 adder 42 also receiving a first segment of a byte stored in accumulator 40. Output of adder 42 causes retrieval of one of modifier combinations stored in 44 and passed to optional buffer 46 from which it is further applied to mod-2 adder 48 receiving the second segment of the byte stored in 40, the sum being fed back and stored at 40 until required to be transmitted at determined intervals. Size of register 40 is equal to degree of encoding polynome i.e. if polynominal is of the 16th degree, the register is divided into 8 low order and 8 high order positions. At the receiver (12) (see Fig. 1, not shown) the data and accumulation in 40 is received into register (26) and passed through gate (28) into register (30) the data being passed to a receiving device and the accumulation through gate (34) to a checker (32) similar to check 20 to permit comparison between the previous and present accumulation. If data is error free checker (32) is cleared but if not, a signal is passed to an indicator (38) of any type which may also cause retransmission of erroneous signals. A method of calculating modifier combinations is described in the Specification.

Title: Improvements in or relating to the regulation of internal combustion engines
IPC: F02D1/00
Filed: 1927-11-12
Abstract: 295,155. Held, G. Nov. 12, 1927. Cam-actuated pumps; lever-actuated pumps; stroke, varying; timing- devices.-The fuel pumps of engines working with heavy-oil injection, particularly two-stroke engines for motor vehicles, are regulated automatically when the engine is running light, preferably by the pressure of the scavenging-air or of the lubricating-oil, whilst during normal running this automatic regulation is put out of action and the pumps controlled by the accelerator pedal or a handle on the steering-wheel. Figs. 1 and 2 show the invention applied to a two-cylinder engine, the fuel pumps 1 of which are actuated by levers 2 and a pair of cams 3. These cams are moved axially for regulating by. arms 4 connected to toothed sectors 5 engaging a wheel 6 on a spindle 6<1>. This wheel 6 is oscillated by an arm 9 connected to the accelerator pedal or hand control, and is also movable axially by a piston 7 acted on by the pressure of the scavenging-air or lubricating-oil admitted at 16, the teeth on the wheel 6 and sectors 5 being helical so that the axial movement of the wheel also adjusts the cams. When the engine is running light the piston is raised from the position shown by a spring 11, so as to respond to variations in the pressure of the scavenging-air &c. due to variations in engine speed; but when the accelerator pedal is depressed, the pressure of the scavenging-air &c. increases sufficiently to move the piston 7 down to the position shown, where it is out of action. The levers 2 are initially adjusted both horizontally and vertically by means of a pair of eccentrics 12, 13 provided at their pivots.

Title: Automatic device for measuring the variations in weight of a substance subjected to an external influence
IPC: G01N5/04
Filed: 1953-11-06
Abstract: 767,926. Electric weighing apparatus. MAURET, P. Nov. 6, 1953 [July 15, 1953], No. 30758/53. Class 40 (1). [Also in Groups XVIII and XL (b)] Apparatus for measuring and recording variations in weight of a body subjected to a controlled heating comprises a balanced beam weighing machine having the body in a weighing pan in a semi-enclosed chamber which also contains the heating source, the variations in weight being indicated by the movement of a light beam reflected from a mirror attached to the balance beam on to a scale, and also by the variations of output from a photo-cell to which the moving mirror acts as a variable shutter. As shown (Figs. 1, 4), a chamber 2 is located inside a housing 3 and contains a lamp 1 and a weighing pan 4 supporting the test body in a cupola 6. A filter 5 may be located between the lamp 1 and the body to restrict the heat to any required wavelength, or to shield the body from direct radiation and subject it only to secondary radiation from the shield. Air flow past the weighing pan 4 is controlled by a damper 7 controlling vents under the chamber 2 and in the throat of a chimney 8, and the heat supply is controlled by a potentiometer 10 adjusting the voltage across the lamp 1. The pan 4 is suspended from the balance beam 12 on a knife-edge on a pin 15, the beam being pivoted on a shaft 16 and carrying at the other end counterpoise weights 21. Damping of the movement is produced by a copper sheet 19 attached to the beam 12, moving between the poles of a magnet 20. The inclination of the beam is measured by a light beam from a lamp 29 reflected by a mirror 18 fixed to the beam 12, and two fixed mirrors 35, 36, the light beam finally falling on a scale on the front of the casing 3. The mirror 18 also acts as a moving shutter between the lamp 29 and a photo-cell 38, whose output thus records on a meter 39 the variations in weight on the weighing pan 4. The moving parts may be clamped by rotating two cams 23 by a knot 28, whereupon two springs 24 lift the weighing pan 4 until pins 25 bear against abutments 26, and a member 27 simultaneously clamps the beam 12. By weighing a substance which absorbs or gives up water in accordance with the humidity of the atmosphere, e.g. a mass of cellulose fibres, the apparatus may be used to measure the humidity in chamber 2.

Title: Improved manufacture of threads from viscose
IPC: D01F2/06
Filed: 1936-11-14
Abstract: The process described in the parent Specification for obtaining curled staple artificial threads from viscose is carried out by subjecting the cellulose xanthate threads while on a draught roller to the action of scrapers or doctors which check the threads in their path and thereby curl them, and then converting the curled cellulose xanthate threads to cellulose hydrate threads.  In an example, ripened viscose made from ripened alkali cellulose is spun into a bath containing ammonium and sodium sulphates.  The xanthate thread, which may be stretched between rods, is withdrawn from the bath by draught rollers and while on the last roller is checked in its path by a scraper and thereby curled.  The curled thread is decomposed to cellulose hydrate in a bath of dilute sulphuric acid and sodium sulphate.
