Title: A new or improved method of and apparatus for the production of internal or externalprofileson clutch teeth for stepped change-speed gears
IPC: B21H5/02
Filed: 1958-12-09
Abstract: 906,651. Making dog-clutches; rolling gear teeth. ZAHNRADFABRIK FRIEDRICHSHAVEN A.G. Dec. 9, 1958 [Jan. 28, 1958], No. 39747/58. Classes 83 (2) and 83 (4). In a method of making internal and external profiles on a workpiece e.g. clutch teeth for stepped change-speed gears, the profile of the workpiece is formed by rough cutting machining and is relieved by cold-rolling with a tool having at least one tooth profile whose teeth are of a pitch corresponding to those required on the workpiece, the tool and the workpiece being radially displaceable relatively to each other. A roller-tool 19, Fig. 1, is carried on a driven spindle 15 centred at one end and mounted in a bracket 13 at the other, the whole assembly being slidable on a slide 11 towards a workpiece 2, 3 on a centred mandrel 7. The slide 11 is moved by a pressure medium device which also exerts the radial working pressure. The clutch rim 2 of the workpiece is initially rough machined to toothed profile and recesses 45, Fig. 5 (not shown), are formed at the base of the teeth to admit material flowing during subsequent rolling by the tool 19 to form external teeth of a clutch dog-rim. The tool may have a pair of rolling rims for the simultaneous relief-rolling of more than one toothed rim on a workpiece. Individual teeth 41 on the tool are tapered in the direction of the width for producing the type of profile indicated in Figs. 6 and 7 (not shown), while the teeth 42 (Fig. 3, not shown) are thicker than the teeth to be formed on the workpiece and produce the form of profile shown at Fig. 8. Teeth 46, 47, Fig. 4 (not shown) may alternatively be provided on a similar tool. In rolling teeth internally on a rough-cut annular dog-rim 21 of a gear selector sleeve 22, Fig. 2, the workpiece 22 is pressed radially, by a roller 29 mounted on a slide 33, against teeth 23 of a tool 25 mounted on a driven spindle 27.

Patent GB-399272-A (GB)
Abstract: 399,272. Time-checks for games. THOMPSON, A., Greystones, Moorgate, Rotherham, Yorkshire. June 2, 1932, No. 15607. [Class 132 (ii).] A time-checking device for billiards, tennis, bowls, or other games comprises an electric clock, means for starting and stopping the clock by closing and opening the switch of an electric light circuit, and means for recording the total time during which the circuit has been closed. When the game apparatus is hired the attendant closes a switch 16 thereby starting an electric clock 11 and illuminating a tell-tale lamp carried by a socket 12. A disc 18 is fitted to the hour arbour and carries a projection adapted to rotate the star wheel 20 of a counter 19 so as to regulate the number of hours the clock has run. At the end of the hiring period the switch 16 is opened and the clock automatically stops. The star wheel may be replaced by an actuating lever. When the game, for example billiards, is played by artificial light, this may be controlled by the switch 16 and the tell-tale light may then be dispensed with. The artificial light may be used to illuminate the marking board. The counter may be replaced by a chart mounted on a cylinder rotating with the hour arbour and marked by a pencil moved to produce a helical record. The switch 16 may be opened and closed by the act of unlocking and locking the marking board.

Straps 17 interconnect presser plate 13 and spacer ring 16 to bias the plate 13 away from flywheel 12 and straps 18 interconnect presser plate 14 and the ring 16. The presence of the resiliently mounted plate 28 is stated to prevent vibration altering the adjusted position of tube 23 whilst the clutch is disengaged. The tube 23 is of spring steel and has an axial gap 25 so that it is an interference fit in bore 24. The clutch is held engaged by a diaphragm spring 19.

[Also in Group XXV] A finger ring comprises three arcuate sections 10, 11 and 12, the sections 10 and 11 being pivotally connected to the ends of the section 12, a curved bridge part 14 fixedly connected to the free end of section 10 and slidably engaging in a tunnel in section 11, an arcuate resilient latch bar 19 concentrically spaced in relation to the bridge part and fixedly connected to section 10 and a catch element 23 within the tunnel and engageable by the latch bar when the free ends of the sections 10, 11 are close together. A projection 18 on the bridge part 14 coacts with the catch element 23 for limiting the opening apart of the arcuate end sections. In the closed position of the sections the nose 20 of the latch bar engages over the element 23 situated in an outer slot at the end of section 11. An end part 17 closes the inner surface of the tunnel which may alternatively be closed over its entire length. In an alternative embodiment in which both end sections 10 and 11 are hollow, the bridge part and latch bar are secured at one end by a rivet within one section and joined together by a pin at their other ends which slide within the other section, the latch bar having a number of grooves one of which a cross-bar selectively engages to vary the size of the ring. Alternatively the latch bar may rest between two spaced parallel members which comprise the bridge part.

The frame 2 comprises hollow longitudinal side members 2 1  and 2 2  supporting a plate 2 3 , each side member 2 1 , 2 2  having slidably fitted therein one end of a bar 7 which has its opposite end rigidly connected to the bumper 8. The bumper 8 and bars 7 may be moved between an extended operative position and a retracted position (shown dotted) by means of a bellows 11, operable by the vacuum created by the engine of the vehicle, and pivoted links 9 which are disposed between the side members 2 1 , 2 2  at 9b and the bars 7 adjacent the bumper 8 at 9a.

Abstract: 1,112,050. Digital electric data processor. WESTERN ELECTRIC CO. Inc. 6 Oct., 1965 [7 Oct., 1964], No. 42351/65. Heading G4A. A data processor comprises means for successively transmitting instruction words to an instruction word register, means for controlling transfer of data between a plurality of memory locations in accordance with an instruction word, and means responsive to an anomalous instruction word for operating the means for transferring in part in accordance with the anomalous instruction word and in part with the instruction word previously contained in the instruction word register. As described (Figs. 1 and 2, not shown) instructions taken in sequence from a store (40), addressed by a programme address register (38) normally incremented by 1 but which may have a new address inserted in it by a transfer instruction, are entered into an order word register (28). A decoder-distributer (34) decodes the instruction and enables the appropriate portions of the processor to perform instructions such as read, write, transfer. A data address portion of the instruction word may be transmitted to an index adder where it can be modified by the contents of a register specified by the instruction word, the new contents defining an address for read-out or read-in or being data to be stored. Words read out of or into store can be masked by a masking register (14), a mask word allowing data bits to be passed in positions where the mask has a 1 and preventing bits from passing where the mask has an 0. In certain anomalous instructions such as an instruction '' store the contents of register Z in a location determined by the contents of Z " or an instruction which involves no data being fed to the index register the operation of the processor is modified to perform a somewhat different operation. Two detection circuits (72, 74) are inserted to detect these two anomalies and if an anomaly is found then a gate (78) is inhibited to prevent the index adder from being reset and thus retains the address or data previously contained therein. In one anomaly an S bit is present in the order register which inhibits transfer of the data address part of the instruction to the index adder and diverts it to a predetermined register (L Register). In this instruction the modifier register is not addressed so no data is fed to the index register. This allows in one instruction a command to read, write and mask with the mask being taken from the data address portion of the instruction word and store or read address being the previous address in the index adder. In the other order an index register is specified but has no effect since the detection circuit prevents the index adder from being reset. Again the data address part of the instruction can be used as a mask and transmitted directly to the mask register.
