Title: Improvements in machines for cutting or generating the teeth of wheels
IPC: B23F5/14
Filed: 1926-12-28
Abstract: 274,350. Sunderland, S. Dec. 28, 1926. Gear-cutting.-In a geargenerating machine of the type in which a reciprocating cutter 4 is moved tangentially on a slide 2 in unison with a rotating blank 5 to generate the tooth profiles, the tangential movement is effected by means of an inclined cam member 6 which is moved horizontally to impart vertical movement to a bracket 14 secured to the slide 2. The member 6 which is operated from the usual cutter-traversing shaft 13 preferably has a travel of about 12 inches, and a series of members having different inclinations may be used for cutting gears of different pitches. Instead of changing the member 6, the pitch may be modified by altering the travel by means of the change gearing driving the shaft 13. Alternatively, the wedge 6 may be pivoted at 9 to a member 7 which has a surface sliding on the machine frame and is provided with rack teeth 7<a> driven by a pinion 12 on the shaft 13. Interchangeable bushes 10 may be fitted on a stud 11 to give different inclinations to the member 6 to cut gears of different pitches.

The contacts are operated only if the inserted card bears the correct code. Each card 7 (Fig. 8) is coded by the provision of notches 7a (see also Fig. 3a, not reproduced) along one edge, and may also carry identifying numbers, photographs &c. In one embodiment, each card receiver 4 is provided with a plurality of spring-urged sliders 17 that normally support a lever 18 to hold a switch 19 closed. A number of the sliders 17, corresponding in position to the notches 7a on the coded card 7 to be accepted, are permanently urged to the right by inserts 20. The remaining sliders 17 are movable only by an inserted, correctly coded card 7 to release lever 18 and open the switch 19. In a second embodiment, the notches 7a on a card 7 align with fixed abutments (10) (Fig. 6, not reproduced), the card edge serving to directly operate a switch (9) on full card insertion. Operation.-Insertion of a coded card into its associated receiver 4 at the beginning of a working period, operates the switch 19 (or (9)) to energize an associated relay-diode circuit in a control module 3 (Fig. 12), which energizes a power pack 1 and the clock 2. The clock pulses are then counted by the associated counter 5. In a first embodiment, the coded card remains in the receiver 4 until the end of the working period, when removal reverses switch 19 (or (9)) to deactivate the counter 5. In a second embodiment, the coded card is removed during the working period, the associated switching means remaining activated until the card is reinserted at the close of the period (not further disclosed). Activation of a counter 5 is indicated by a lamp. Insertion or withdrawal of a coded card into (or from) its receiver 4 sets an associated bi-stable circuit 21 to activate a detector 22. The detector 22 then feeds the address of the receiver 4 to an interrogator 24, simultaneous with the time from a digital clock 26; the information is recorded by a tape punch 27, and the bi-stable 21 reset. An emergency power supply may be provided. Units 2, 3, 4 and 5 may be plugged into a common housing.

Title: Improvements in or relating to the thermal or thermochemical treatment of metal wire or the like
IPC: C23C16/54
Filed: 1932-11-25
Abstract: 406,440. Wire-heating furnaces. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London.-(Assignees of Patent-Treuhand-Ges. fur Elektrische Gluhlampen; 11, Ehrenbergstrasse, Berlin.) Nov. 25, 1932, No. 33468. Convention date, Nov. 25, 1931. [Class 51 (ii).] To form an efficient seal for the reaction chamber when the continuous thermal or thermochemical treatment of metal wire or the like is carried out at a pressure less than atmospheric, there is provided on each side of the reaction chamber through which the wire is passed and in which it is heated a narrow tube filled with mercury connecting the reaction chamber to auxiliary chambers arranged one on each side of the reaction chamber and each having a narrow passage communicating with the atmosphere, the pressure in the auxiliary chambers being maintained at a value intermediate between atmospheric pressure and the pressure of permanent gas in the reaction chamber. One or more additional auxiliary chambers, connected to one another by narrow channels, may be provided on each side between the chamber next to the reaction chamber and the atmosphere, the pressure in each chamber being maintained at a value intermediate between the pressures on either side of it. In the form shown a wire 8 is drawn through a narrow channel formed by a hole in a rubber stopper 17 into an auxiliary chamber 6 and thence through a narrow tube 4, the middle part 4<1> of which is enlarged and filled with mercury, into a reaction chamber 1. While passing through the reaction chamber the wire is heated electrically by current passed between contacts 11, 12, and is subjected to the action of zirconium tetrachloride vapours produced by vaporizing the tetrachloride in the chamber either by the action of a burner or by the heat generated in the wire. The coated wire passes out through the narrow tube 5, the middle part 5<1> of which is filled with mercury, and the auxiliary chamber 7 connected to the atmosphere by a hole in a rubber stopper 18. The auxiliary chambers 6, 7 are connected by conduits 19, 20 and a common conduit 21 to an exhaust pump and the reaction chamber 1 is connected to a high-vacuum pump by a conduit 15, the conduits 21, 15 being provided with stop-cocks 22, 16. The conduits 15 and 21 are connected together by a conduit 24 with a stop cock 23, so that all the chambers may first be brought to a low pressure by the exhaust pump connected to conduit 21 and the reaction chamber alone then brought to a high vacuum by the pump on the conduit 15. The mercury chambers 4<1>, 5<1>, are connected to the conduits 19, 20 respectively by tubes 25, 26 provided with stop cocks 27, 28 which can be removed for introduction of the mercury. The rubber stoppers 17, 18 may be replaced by narrow tubes filled with mercury.

Filed: 1975-08-12
Abstract: 1520015 Error correction SPERRY RAND CORP 12 Aug 1975 [3 Sept 1974] 33479/75 Heading G4A Digital apparatus including error-correcting means comprises a register 10 for storing information bits and check bits, the stages of register 10 providing inputs to a syndrome generator network 12 arranged to generate syndrome bits S t , and to a parity predict network 22 arranged to generate a parity predict bit L, a parity check network 24 being arranged to receive the syndrome bits S t  and the parity predict bit L and to produce therefrom a parity check bit C s  indicative of whether or not the syndrome bits S t  are error-free, each stage of the register 10 providing an even total number of inputs to the syndrome generator network 12 and to the parity predict network 22, and each intermediate gate within the syndrome generator network 12 and the parity predict network 22 (i.e. the upper gates shown in the Fig. which precede the output gates of networks 12, 22) having its output connected to an odd number of subsequent logic elements. The check bits may be encoded in a Hamming code enabling singleerror correction, the syndrome bits S t  being fed to a further network (not shown) to accomplish this error correction. All the networks shown may be constructed from EXCLUSIVE-OR logic gates. The even total number of inputs from each stage of register 10 to the networks 12, 22 ensures that a failure of any gate within networks 12, 22 will be detected, whereas the odd number of connections to the output of each intermediate gate within networks 12, 22 ensures that an improper clocking of such an intermediate gate will be detected. In a modification which allows detection of double errors in the word stored in register (30), Fig. 2 (not shown), an overall parity bit (P) for that word is also stored in register (30), the overall parity bit (P) being fed as inputs to an overall parity gate (40) contained within syndrome generator network (32) and also to parity predict network (44), an overall parity bit (P 0 ) formed by overall parity gate (40) forming an input to parity check network (46). The register 30 and networks 32, 44, 46 are respectively analogous to register 10 and networks 12, 22, 24. A modified form of Fig. 2, which enables the number of inputs to the syndrome generator network (32) and to the parity predict network (44) to be reduced, is described, Fig. 3 (not shown), wherein two further intermediate gates (60, 64) are provided in the syndrome generator network (52) (analogous to network (32)).

Patent GB-1477196-A (GB)
Title: Process and apparatus for metallising sheet-like substrates
IPC: C23C16/48
Filed: 1974-07-30
Abstract: In the process for metallising sheet-like material by decomposing gaseous metal compounds there results a line-like concentration of the heat radiation, by means of an optical system, on the surface of the material to be metallised. In this arrangement, a relative movement of the material transversely to the line of the heat concentration of the optical system is made possible, owing to the constructional design of appliances in accordance with the shape of the material. For the purpose of metallising continuous material webs (8), the walls of a metallisation chamber (1) enclosing the radiation source (4) have feed-through slits (6, 6'), opposite one another, for the material. The chamber (1) has supplies (9) and outlets for the gaseous metal compound. For smaller sheet-like material there is provided an appliance having means for the back-and-forth movement of the material, in which appliance the material is introduced piece by piece after opening the chamber (1), and after completion of the metallisation process can be removed again. Employing less energy, the process allows more uniform metallisation of the material without the risk of excessive heating of the material. <IMAGE>
