Title: Electromagnetically controlled safety belt retractor
IPC: B60R22/34
Filed: 1973-06-05
Abstract: 1410247 Electromagnetically-controlled safety belt retractor ALLIED CHEMICAL CORP 5 June 1973 [6 July 1972] 26825/73 Heading A3V [Also in Division H1] A safety 'belt retractor comprises a reel journalled on a supporting frame 7 and biased by a spring 64 in the wind-up direction, a flange 24 on the reel shaft 32 having ratchet teeth engageable with a pawl 33 biased to its locking position by a spring 34, a cam follower 51 attached to the pawl and cooperable with a cam 17 which is movable between a first position in which the cam releases the follower 51 to allow locking of the reel and a second position in which the cam and follower hold the pawl disengaged from the ratchet teeth, an armature 53 on the cam, a cooperating electromagnet 25 which when energised holds the cam in its second position to prevent locking of the reel and a clutch disc 41 which moves the cam to its second position on initial belt withdrawal. The electromagnet 25 is connected to the battery of a vehicle in which the retractor is fitted in series with an inertia switch, a pressure sensitive switch responsive to the vehicle's hydraulic brake system and the vehicle ignition switch so that when the last-mentioned switch is closed the electromagnet is normally energised unless the vehicle accelerates or decelerates by a predetermined amount and/or the brakes are applied. Accordingly a raised portion 61 of a cam slot 52 normally holds the follower 51 in the unlocking position. On deenergisation of the electromagnet slight belt withdrawal displaces the cam 17 by means of the clutch disc 41 to its first position. A belt follower 16 prevents locking of the reel while the belt is substantially fully wound thereon. Fig. 8A shows an inertia switch suitable for use in the supply circuit of the electromagnet. Vehicle acceleration or deceleration causes a pendulum 78 to swing which raises a spring strip 89 through a bearing member 79 and lifter member 85 and thereby opens switch contacts 91, 93.

Abstract: 266,418. Schidrowitz, P., and Vultex, Ltd. Oct. 28, 1925. Addition to 193,451. Latex, treating; vulcanizing.-The process of the parent Specification, namely, the direct vulcanization of uncoagulated rubber latex under such conditions as to preclude any substantial coagulation, is applied to concentrated latex, preferably a paste, containing at least 53 per cent of caoutchouc. Conditions inhibitive of coagulation are a non-acid mixing or the addition of basic reagents or protective colloids such as soaps, alkali lysalbuminate, or casein. The vulcanization may be varried out at high or low temperatures, and accelerators, operating in a basic medium may be employed. The incorporation of ingredients, such as sulphur or polysulphides, accelerators, fillers may be effected by stirring, masticating, or rolling, with the avoidance of grinding action, and may be made at any convenient stage of the process. Several examples are given of which the following is typical : 3 parts of sulphur, 0.6 parts of zinc oxide, and 0.03 parts of the condensati.on product of piperidine and carbon bisulphide are stirred into a cream with a dilute solution of casein, and the cream is mixed with 100 parts of latex containing 60 parts of rubber. This is heated for 40 min. at 70‹ C. following a rise of 30 min., with a final rise of 15 min. to 80‹ C. The product is a spreadable, reversible, uncoagulated, vulcanized mass.

Title: A plant for sorting articles
Inventor: RADUTSKY GRIGORY AVRAMOVICH
IPC: B65G1/133
Filed: 1969-05-29
Abstract: 1,274,331. Discharging laundry articles from an endless conveyer at selected points. VSESOJUZNY PROEKTNO-KONSTRUKTORSKY INSTITUT SVAROCHNOGO PROIZVODSTVA. 29 May, 1969, No. 27160/69. Heading B8A. By pressing an appropriate key 47 (Fig. 5) one of a series of carriers 9 (Fig. 2) is caused to drop an article of laundry on to a platform 4 at a predetermined station. As each article is deposited on a platform 4 the latter automatically lowers so as to keep the top of the pile at a constant height. Deposition of an article on to the platform 4 takes place by the action of a lever 10 on the machine frame when it is set to co-operate with a lever 7 forming part of the carrier mechanism. The lever 7 brings about the movement of a comb-shaped member 17 which interdigitates with fixed comb elements of the carrier. The lever 10 is set by the action of a member 61 of a memory device (Figs. 4 and 5). The lowering of the platform 4 is brought about by the action of a cam 6 carried by each lever 7. This coacts with a follower 31 to rotate an arm 19 which thus removes a pin from a member 28 carried by an arm 20. The arm 19 is connected by a spring 21 to the arm 20 and the latter is rigid with the pivot of a feeler arm 18. The outer end of the latter is thus turned by this action to rest on the top of the pile of articles on the platform 4, and the higher the pile the greater the degree of relative movement between the levers 19 and 20. This results in a proportional displacement of a pawl 22 and hence a member 25 which operates a ratchet mechanism 26, 27 (Fig. 2), for driving downwards the platform 4. The memory drum 44 is rotated by the action of a cam 41 on the drive-shaft of the conveyer. This operates (via a linkage 42, 43) a pawl and ratchet mechanism on the drum 44. The latter carries sliders 46 which are normally carried across the periphery of the drum 44 by the action of a member 54 (projecting through a slot in the fixed casing of the drum) of a dog 50 carried by an endless member 57. The latter is rotated in synchronism with the conveyer by a shaft 60. If a key 47 is depressed, the slider 46 is caused to stop at a position in its travel (axially of the drum), corresponding to the particular selected platform 4. As the drum rotates, the slider 46 then operates a read-out element 61 which in turn activates the particular lever 10 at the selected platform 4, thereby causing the desired conveyer carrier 9 to deposit its laundry article at the selected platform 4.

Abstract: 727,716. Casting composite articles and joints. GENERAL ELECTRIC CO. Oct. 6, 1953 [Oct. 8, 1952], No. 27426/53. Classes 83 (1), 83 (2) and 83 (4). Welding by fusion.-In a method of making a turbo-machine bucket-wheel by uniting preformed buckets with a central wheel web, the buckets are assembled about the periphery of a mould with their base portions connected together to provide a path for electric current, electrically-heated to a predetermined temperature and then molten web-forming material is poured into the mould. The individual buckets, Fig. 1, may be made by extrusion, forging, machining from solid stock &c., but are preferably precision cast, as by the lost-wax process, and comprise a blade portion 1, a radially projecting locating tang 3 and a base portion 2 comprising a fusion tang 6 and an intermediate base portion 5 having transversely extending arcuate recesses 5a, 5b. A number of buckets are then supported in a welding fixture, Figs. 2 and 6, clamped by rings 7, 9 and connected by tack welds 11, 12 to form a complete annular row, the tangs 6 forming a closed electricallyconductive path. Ceramic rods or tubes 21 are inserted in the substantially circular recesses formed by co-operating recesses 5a, 5b and the assembly inserted in a shell mould 14, 15, being supported therein by engagement of the tangs 3 with recesses adjacent clamping bolts 16 and yieldable packing rings 17, 18 of asbestos or fibre glass. The bucket assembly is heated by low voltage induction coils 24, 28 which induce eddy currents in the path formed by the tackwelded fusion tangs. Metal is then poured through the gate 30. After cooling, the shell mould and packing rings are stripped from the casting which is then machined or ground to size, the tangs 3 being thereby removed. Before or after machining, the ceramic tubes &c. are removed by driving them out or by chemical means, and any metal which may have entered the gaps 21a between the tubes and the bucket bases, is cleared out by reaming or grinding.

[Also in Division H3] In the mass spectrometer of the parent Specification the controlling alternating voltage is periodically interrupted with a relatively long duty interval in order to provide a longer time for the accumulation of ions in the oscillatory space at lower pressures. A circuit for supplying keying pulses of variable periodicity includes a multivibrator 12 which is controlled by rectangular pulses derived by pulse shaper 11 from a low frequency sine-wave or sawtoothwave generator 9. The generator 9 sweeps the frequency of the high frequency generator 8 in alternate half-cycles and the multivibrator 12 produces further rectangular pulses of lower periodicity which are combined with pulses from the pulse shaper 11 to operate the high frequency generator 8 only when the two sets of pulses coincide. This generator 8 operates during one half-cycle of the low-frequency generator 9 and is then prevented from operating over several cycles.

Filed: 1966-06-21
Abstract: 1,109,048. Analogue to digital converters. STANDARD TELEPHONES & CABLES Ltd. 21 June, 1966, No. 27602/66. Heading G4H. In a P.C.M. system the coder comprises a plurality of bi-stable coding elements, 1-64, each having a different weight, means (junction A) for generating a signal representing the difference between the analogue value and the sum of the weights of those coding elements set, a bi-stable feedback element set when the analogue signal is exceeded to generate a feedback signal, and means for applying the difference signal and the feedback signal (if any) with the correct polarity to the coding elements. A damped oscillatory waveform is superimposed on the combined difference and feedback signal and the coding elements set sequentially until a balance is reached. The signal from the feedback element, which appears when the analogue input is exceeded, is applied to the inverted difference signal at B so that some of the lower-valued elements are switched off. The difference signal then becomes positive again and the feedback signal ceases. The feedback element stabilizes the operation of the system. In order that this shall operate in both directions the threshold levels at which the coding elements are set is biased by half the value of the feedback signal. In addition a dummy coding element D is provided, the weight of which is smaller than the smallest digit value but greater than the threshold level of the feedback element. Alternatively short pulses could be imposed on the difference signal having an amplitude just greater than the feedback element threshold level. The circuit is described in detail, Fig. 4 (not shown).
