Title: Improvements relating to chiming and striking mechanism for clocks
IPC: G04B21/02
Filed: 1932-10-18
Abstract: 407,435. Clocks. HAYCOCK, H., HAYCOCK, F. W., and HAYCOCK, H., 8, Clifton Road, Ashbourne, Derbyshire. Oct. 18, 1932, No. 29075. [Class 139.] Striking and chiming mechanism includes a lever (19) riding on the periphery of a locking disc (10) having three recesses (11-13) and a raised cam (14), the lever being lifted out of the recesses at the three quarter hours but being lifted off the cam only at the hour, the lifting of the lever actuating an arm (20) which carries a member (21) normally arresting a peg on a wheel to prevent chiming or striking, whereby raising of the lever releases the peg. The locking disc 10 has notches 11, 12, 13 for the first three quarters of the hour and a cam 14 for the hour chime. Disc 10 is driven by a chiming spring and drives a train 24-27, 29-31, of which the wheel 27 has a pin 28 and wheel 31 has a pin 32. A pin 15 on disc 10 rocks the lever 42 which coacts with the striking rack 43 and warning pin 44. The notches and cam of disc 10 coact with an arm 19 rigid on shaft 16 together with an arm 20 ; the latter has a U-shaped lateral extension 21 having a slot 22 through which the pin 28 passes at certain times. The two arms of the U are stepped relatively to one another. Arm 19 is controlled also by a pin 38 on a bell-crank 36 which is rocked by pins 34, 35 on the minute wheel 33. Pins 34 are equidistant from the centre of wheel 33, but pin 35 is farther out, to control hour-chiming. Wheel 24 drives the spindle 40 of the chiming drum. At one of the quarters of the hour, a pin 34 rocks bellcrank 36 so that its pin 38 raises arm 19 out of a recess in disc 10. Arm 20 is moved with arm 19 so that plate 21 moves to allow pin 28, which previously rested against the top limb of plate 21, to slip through the slot 22. Almost immediately bell-crank 36 arrests pin 32 on wheel 31. When the pin 34 wipes free of the bell-crank, the latter drops and releases pin 32 and also allows arm 19 to ride on the periphery of the disc 10. Chiming then proceeds until arm 19 falls into the next notch 11-13. This restores arm 20 to arrest the pin 28. At the end of the third quarter chime, arm 19 rides up on to cam 14, thus raising, instead of lowering, arm 20 and its plate 21 whereby the lower limb of plate 21 now arrests the pin 28. To release the hour chime, the pin 38 raises arms 19 and 20 still more, so that pin 28 slips underneath the lower limb of plate 21 instead of through slot 22. This additional raising can only be effected by the pin 35, since it is farther out than pins 34. During the hour chime, pin 15 rocks lever 42 to initiate striking, but striking does not take place until the chiming is finished, since arm 19 then falls into notch 11 and an arm 45 rigid with shaft 16 then releases the warning pin 44.

Title: Explosive actuated tools for driving studs or other fastener elements
IPC: B25C1/14
Filed: 1961-08-16
Abstract: 936,696. Cartridge-operated fastener driving tools. OLIN MATHIESON CHEMICAL CORPORATION. Aug. 16, 1961 [Sept. 26, 1960], No. 29650/61. Class 119. Relates to a cartridge-operated fastener driving tool in which the cartridge is fired by means of a hammer blow applied to the head of a striker member 2 and the explosive force is transmitted to the fastener through the intermediary of a piston member 3 slidable in the tool barrel 1. According to the invention, the cartridge is carried by the piston member 3 which is withdrawable from the end of the barrel for loading purposes. The piston member may be constructed as described in Specification 912,568 having in its upper end a longitudinally and eccentrically arranged cartridge chamber 13 which is opened laterally by a slot 14 to the outer periphery of the piston 3 to enable a tool to be inserted for ejecting the spent cartridge. Balls 15 mounted in cavities 16 in the barrel 1 are normally held in protruding position by means of a spring-pressed sleeve 17 to arrest the piston 3 by engagement with a shoulder formed thereon. The sleeve 17 has recesses 18 so that when it is moved upwardly against the action of a spring 11, the balls 15 are released, enabling the piston 3 to be withdrawn for ejection and re-loading. Further balls 21 actuated by the sleeve 17 are provided in barrel cavities to prevent contact of the striker with the cartridge in the piston during its insertion into the barrel. The arrangement is such that when the sleeve 17 is in position to release the balls 15 to permit withdrawal of the piston 3, the balls 21 protrude into the barrel to give protection against the striker 2 and when the sleeve 17 is in position to cause the balls 15 to protrude into the barrel as arresting means for the piston, the balls 21 are released into recesses 22 in the sleeve 17. A bearing member 4 at the upper end of the barrel slidably receives the shank of the striker 2 and encloses a cage 5 having spring-pressed rollers or balls 6 acting against internal sloped surfaces 7 on the bearing member and gripping the striker shank to prevent accidental firing. The rollers or balls 6 are released by means of release balls 9 forced against the lower end of the cage 5 by means of a sleeve 10 when moved downwardly against the action of the spring 11. The sleeve 10 is urged normally to the upper position in which recesses 12 in the sleeve register with the release balls 9 which are thus free and the rollers or balls 6 grip the striker shank.

Title: Improvements in or relating to braking apparatus for use with pithead winding mechanism and the like
IPC: F16D65/14
Filed: 1952-11-24
Abstract: 702,260. Winding drum brakes. BLACK, G. A. Nov. 24, 1952, No. 29684/52. Class 103(1) In braking apparatus for pithead winding equipment wherein the brake shoes are operatively associated with one or more actuating springs, the hydraulic pressure for opposing the springs and controlling the brake exceeds 1,000 lbs. per square inch and is preferably of the order of 3,000 lbs. per square inch. By using such high operating pressures, the slow operation due to the inertia effects associated with the large volumes of liquid to be displaced in known systems operating at about 100-200 lbs. per square inch is avoided and due to the small size of the pipes required operation is almost instantaneous so that the trip valve for emergency operation may be in any convenient position. As shown in the drawing, the hydraulic cylinder for opposing the main application spring nest 4 has one conduit leading to the trip valve 11<SP>1</SP> controlled by the overspeed mechanism 14 and another conduit to the supply pumps 11 and 12. Normal service control is by a variable pressure relief valve 16 controlled by the hand lever 17. The relative shape of the shoes 1, 1<SP>1</SP> and the positioning of the pivotal points 3, 3<SP>1</SP> may be deduced in the manner described in Specification 701,677.

Abstract: 1,187,490. Sub-station circuits. STANDARD TELEPHONES & CABLES Ltd. 21 June, 1968, No. 29773/68. Heading H4K. In a PCM telephone system in which subscribers' subsets are connected in a unidirectional transmission loop LL, transmission from one subset to another being round one part of the loop and transmission in the opposite direction being round the remaining part of the loop, each subset has a shift register SR recording all incoming PCM codes and for recording PCM codes for transmission from the subset in a channel seized on the loop during which channel time a switch A is operated to break the loop to terminate an incoming PCM code and to send a PCM code set up on SR. The subset microphone has an associated coder PCMC and store CS from which a PCM code is passed in parallel to register SR to be read out serially on to the loop by clock pulses during the seized channel. The code read out of SR is replaced by an incoming code in the same channel the received code being read out in parallel to store DS and decoder DS driving the subset earpiece. As shown in Fig. 3 the switch A comprises the AND gates SRO, LLI, and the NAND gate LLO, gate SRO being primed by channel pulses to gate the output of register SR into the loop LL which due to inverter INV is broken by gate LLI. A clock-driven bi-stable FF effects retiming and regeneration of all bits on the loop, gates LL1 and LL2 producing a balanced output.

Abstract: 1381214 Bending glass tubes PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 22 June 1973 [27 June 1972] 29773/73 Heading C1M In the manufacture of a tubular lamp envelope of which the glass tube 1 or 13 is curved in a flat plane over at least a part of its length; an initially straight tube 1 or 13 is softened by heating and then curved around a bending jig 5, 6 or 16 by co-operation with one or more bending members 2, 3 or 14, 15; is inflated as by puffs p, p to a substantially circular crosssection and then cooled, the curved tube being in, or being given, a horizontal position during at least the greater part of the period of cooling to a temperature at which deformation due to gravity does not occur and the bending members 2, 3 or 14, 15 being removed as soon as the inflation operation has been carried out and the tube is horizontal. Preferably curving is effected with the tube horizontal. In both constructions disclosed, the bending jig 4 or 16 is divisible into two parts 5, 6 and (21, 22) in the plane of the tube and according to Fig. 2, the jig 4 and curved tube 1 are supported in the horizontal position by a plate 7 with an aperture 8, very slightly larger than the jig, so that both parts 5 and 6 of the jig 4 can be removed, as well as the bending members 2, 3, for re-use in further operations, while the tube 1 on the plate 7 continues for further treatment. According to Fig. 3, one part (21) of the jig acts as a supporting plate so that only one part (22) can be reused immediately. In both cases, the support plate 7 or jig part (21) is provided with pivoted holding members 11, 12 which can be hooked over the ends 9, 10 of the tube 1. The bending members may be tongs 2, 3 or rollers 14, 15.

Title: Improvements in or relating to the production of machine-set type composition
IPC: B41B7/04
Filed: 1937-11-01
Abstract: 486,074. Type - making machines. DEWHURST, M. R., and MONOTYPE CORPORATION, Ltd. Nov. 1, 1937, No. 29806. [Class 100 (iii)] Strip-perforating machines; justifying type; keyboards.-Relates to the method of composition described in Specification 481,380, wherein separate interword spaces are abolished, and the justification-fraction is cast on to the initial character of each word of a line by association of the perforation made by the transfer-punch with the signal representing the character. According to the invention, separate air - controlled locking- devices are provided for the strip-feeding mechanism and for the units-counting mechanism, and the locking-device for the stripfeeding mechanism can be put out of action by means of a hand-operated valve, in order that the initial character of each word may, when desired, be cast with an additional amount, for example, four units, to provide adequate word-spacing in the larger sizes of type. The locking-device for the counting- mechanism comprises a piston A<1>, Fig. 8, mounted in a cylinder A, and having at its outer end teeth to engage those of the unitswheel N<1> and to prevent its rotation. The strip-feeding mechanism is operated, as heretofore, by a. driving-motor O<6>, Fig. 5, and a return motor O<7>, to which air is admitted alternately by a slide-valve O<8>, which is operated from the punch-bars through a universal bar. The locking-device for the stripfeed comprises a pistonvalve B<1>, mounted in a cylinder B, and serving, when moved, to cut off the air supply to the motor O<6>. Air is supplied to the cylinders A, B through pipes A<2>, B<3> leading from a valve-casing C, which contains a hand-operated valve C<1>. Air is supplied to the valve-casing through a pipe c from the motor of the transfer-punch whenever the space-key is operated. The valve C<1> can be adjusted to admit air to one or both of the cylinders A, B, or to exclude it from both. When the justification-fraction alone is to be applied to the initial character of each word, the valve is turned so as to admit air to both cylinders. When an additional width of, say, four units is also to be added to each initial character, to provide larger word-spaces, the valve is turned so as to admit air to cylinder B only. The space-key has, as heretofore, three adjustable projections, by means of which it can operate different members of the permutation system. For large word-spacing, these are adjusted to operate, in addition to the transfer-punch, a punch-bar which carries no punch but causes an amount of four units to be registered. Each initial character will then be cast of the normal body-width together with an additional width of four units and one increment of the justification - space. To equalize the sense of touch of the space-key, which may operate either one or two punchbars, it is provided with springs D', Fig. 14, which bear on the keyboard-frame. Specifications 8633/99 and 17199/08, [both in Class 100], also are referred to.
