Title: Improvements in or relating to electric signal circuits employing magnetic cores
IPC: H04Q3/00
Filed: 1957-03-22
Abstract: 817,985. Exchange systems. WESTERN ELECTRIC CO. Inc. March 22, 1957 [April 13, 1956], No. 9466/57. Classes 40 (4) and 40 (9). The 31 x 32 cores 10 of a magnetic matrix store 15, Fig. 4, are linked with separate telephone lines 11. The cores are biased positively and negatively respectively by busy and free lines but any change in the magnetic state of a core necessary to record the condition of the corresponding line does not take place until the core is interrogated. Only a change of condition is signalled on the common output winding 61. Each core is linked with horizontal, vertical and diagonal interrogation windings H1 to Hn,.V1 to Vn-1, D1 to Dn. To be effective, interrogation pulses in all three windings of a core must coincide and a change of magnetic state can take place only in the direction of the bias. All the 992 lines are tested every 5 millisecs., the cores being interrogated in sequence along diagonals D1 to Dn in that order. Interrogation pulses are applied in pairs to each winding, a positive pulse being followed immediately by a negative pulse as at 47, Fig. 3. When a core is not switched, the successive pulses drive it through a minor hysteresis loop. The cumulative destruction of the magnetic record is negligible. Pulse driving circuits 21 are controlled by a common clock source 30. Line circuit, Fig. 2.-When the loop is open at station S5, core 10 is magnetically biased negatively by coil 14 connected to a tapping 25 on battery 19. When the loop is closed, the core is biased positively by coil 12. Speech is transmitted over transformers 16, 17 and conductors 27, 28. The core is switched when windings Hn, V3, D4 are pulsed together in the same direction as a bias opposed to the remanent flux. Pulsedrivingcircuits 21, Fig. 3.-Tube 32 applies a magneto-motive force to all the cores 31 at the leading edge of a clock pulse 36 from source 30, and tube 33 applies an opposite magneto-motive force at the trailing edge. A circuit 20, which is not described in detail, permits only one core 31 to be driven round the full hysteresis loop. Positive and negative pulse pairs 47 are generated in the output windings 41 connected to leads H1 to Hn. Both tubes 32, 33 are normally biased to cut-off. The leading edge of pulse 36 makes tube 32 conduct and transmit a negative pulse 42a to the grid of tube 33. At the -trailing edge of 36, a positive pulse 42b is transmitted to tube 33 which conducts and returns'the cores 31 to normal.

Title: Broaching machines
IPC: B23G9/00
Filed: 1962-03-13
Abstract: 965,946. Broaching. SUNDSTRAND INTERNATIONAL CORPORATION S.A. March 13, 1962 [Oct. 2, 1961], No. 9685/62. Headings B3B and B3L. A screw or like nicking machine comprises a rotatable wheel 21 for carrying the screws 42 against a broaching blade 90. Screws from a shoot 30 are positioned in the notches 41 of work-holders 40 on the wheel 21 by a notched feed-disc 31 from which the screws are stripped by a spring 68. A bevel-gear 70 on the front of the wheel 21, through a shaft 72, Fig. 10, driving clutch pins 74 pressed by a spring 75 into recesses in the disc 31, drives the disc which may be released by the pins if jamming occurs. This release, by means of a cable 81, Fig. 1, operates a switch 80 which operates an indicator light and stops the machine. For each work-holder 40 there is a slidable member 43 having a sloping surface 44 at one end and roll 52 at the other which follows a cam 50. This, against the influence of springs 46, retracts the members clear of the notches 41 for the loading operation and allows them to advance over the occupied notches. A hammer 60 on a pivot 61 and biased by a spring, has a sloping inpact surface 65 for striking the member 43. If the hammer moves back too far after striking a blow, indicating that the member 43 is incorrectly positioned, its backing plunger 62 operates a switch 66 which operates an indicator light and stops the machine. The radius of the screw-heads is sensed by a pivoted member 55 biased by a spring-loaded plunger 56. If the head is too high, the plunger is raised and operates a switch 58 which stops the motor driving the wheel 21 and operates an indicator light. A blade 90, Fig. 12, at each of the broaching stations 23, 24 is pressed against a seating 101, Fig. 5, by screw-operated pads 109 carried by a member 102 pivoted at one end and having a slot 105 at the other for engaging releasably a post 106. The back 92 of the blade engages a fence 110 pivoted at one end 125 to a slide 111, adjustable by a screw in a channel formed in the base 100, and at the other adjustable about end 125 by an eccentric 126, so that the depth-of-cut per tooth can be adjusted while maintaining the positions of the last tooth to cut. A key on the base 100 guides the slide 111. A deburring tool (not shown) may treat the screw-head before the cam 50 again retracts the member 43, releasing the screw into shoot 32. If the screw remains in the work-holder, its continued presence is detected by a pivoted feeler 86 operating a switch for stopping the motor and operating an indicator light. Drive from the motor to the wheel 21 is by worm-gearing, Fig. 11 (not shown).

Patent GB-232770-A (GB)
Title: Improvements relating to rove stop motions for spinning machines
IPC: D01H13/18
Filed: 1924-04-17
Abstract: 232,770. Walls, A. G., and Walls, R. N. April 17, 1924. Delivery, stopping.-Relates to mechanism for stopping the delivery of jute, flax, tow, hemp and other roving in spinning-machines of the kind wherein the roving is moved longitudinally of the rollers and clamped when an end breaks. A detector or feeler arm m, Figs. 7 and 8, is mounted on a spindle o, which is loaded by an adjustable spring s and a link t so arranged in relation to a radial arm u on the spindle that it operates as a toggle-mechanism, the maximum effort being exerted when the detector moves after breakage. When an end breaks an arm v of a fork lever on the spindle moves a detent roller q, Fig. 8, from beneath an arm r, loaded by an adjustable torsion spring to counterbalance the weight of a rod x to the desired extent. The rod x thereupon falls and allows a pawl h, Fig. 1, to engage a ratchet wheel i, whereby the rove shifting and clamping means is positively operated. The pawl h is carried on a trip-plate e, Fig. 2, which, upon movement of the pawl by the ratchet, releases the lever a so that it is operated by a spring b to remove the roving from the bite of the rollers. The movement of the lever a hastens the movement of the trip-plate and pawl and so ensures the disengagement of the pawl, the disengagement being further aided by the lifting of the pawl by a lug i on the casing. A projection 9 on the pawl engages a lug 10 on the lever 11, which operates a jawed lever 16 and thereby clamps the roving against a single or double co-operating jaw on the casing. The parts are reset by moving the detector lever m to the " off " position, whereby a spring arm w operates the detent roller q and raises the arm r and the rod x, and by moving the lever a, whereby the trip-plate e is re-engaged and the pawl h advanced. A light spring acting upon the lever 11 frees the roving from the clamp. The detector m is hinged to the spindle o so that it is raised by the eye-board during doffing. A guide eye 18 is mounted on the cover plate 13 or upon the lever a above the guide spout 19. The casing l of the detector apparatus is dust-proof and a sleeve z connected to the rod x is arranged to shroud the guide tube y. Specifications 1912/70, 17848/02, and 26939/09 are referred to.

Abstract: 1277007 Trench cutting apparatus L P S WILSON 25 June 1969 [25 June 1968 25 July 1968 24 Feb 1969] 30276/68 35671/68 and 9830/69 Heading E1F Trench cutting apparatus comprises an endless cutter chain 11 on an elongate support 12 linearly movable in a carrier 13 for lowering into the ground. Trenches can be dug in a vertical or inclined plane at the back or side of the supporting vehicle by controlling extension of rams 14-16 and 20-21. The rams can be automatically controlled to keep the support in the desired plane irrespective of the tilt of the vehicle. The rams 20, 21 may be replaced by a screw mounting. The carrier 13 can be rotated about its longitudinal axis by a ram 22 so that the chain can follow the direction of the trench as the vehicle changes direction. The chain is driven by an hydraulic motor 30 mounted on the top of the support 12. The motor may be used to move the support in the carrier by locking the chain to the carrier and driving the chain. Alternatively the support may be moved by ram 40 which can be controlled automatically to maintain the trench at a required depth with respect to a reference wire. Excavated material may be carried through the carrier and deflected by plates, possibly aided by water or gas blasts, into a truck, or the material may be heaped to one side of the track. There may be more than one chain, or side cutters may be mounted on a single chain.

Title: Rochelle salt piezoelectric crystal apparatus
IPC: H03H9/02
Filed: 1942-07-17
Abstract: 554,788. Piezo-electric crystals. STANDARD TELEPHONES & CABLES, Ltd. July 17, 1942, No. 9959. Convention date, May 9, 1941. [Class 40 (v)] A rectangular Rochelle salt crystal element is cut with its major plane at right-angles to the X or Y axes of the natural crystal and has its major dimension at an acute angle to the other two axes which is chosen to give uncoupled double resonance in the width and length exten sional modes two sets of independently controlled electrodes being provided, and the ratio of width to length being in the range of .2 to 1.0. Fig. 1 shows a Rochelle salt crystal plate which is in effect an X-cut crystal with the length dimension L rotated about the X-axis to form an angle α with the Y-axis. When α = 49‹56<SP>1</SP> there is substantially no coupling between the fundamental extensional mode along the width dimension W and the second harmonic extension mode along the length dimension L. These modes may be excited by the electrodes 10...13, Fig. 5, and independently controlled as to frequency. The lower pair of electrodes may be replaced by a single electrode and an earthed strip electrode may be placed between the electrodes in the gap 7 to reduce mutual capacity. By varying the angle of line 7 relative to the axes of the plate, the relative impedances of the two modes may be varied. The impedance of the crystal is dependent on the thickness T. A similar Y-cut crystal is described, Fig. 2 (not shown) having its length dimension at 42‹ 261 to the X axis. The crystals may be mounted by clamping about the nodal points, which for the doubly resonant crystal lie along the major axis about one quarter of the length from each end, or they may be suspended on wires in a sealed tube. The crystals may be connected in the filter circuits described in Specifications 531,662 and 542,452. Specifications 532,925, 533,204 and 553,457 also are referred to. The Specification as open to inspection under Sect. 91 also describes a crystal with its plane at right angles to the Z-axis and its length at an angle of 45 degrees to the X and Y axes. This is unsuitable for double resonance. This subjectmatter does not appear in the Specification as accepted.

Title: Microwave discharging light source device
Inventor: UMAGOME KAZUO
IPC: H01J65/04
Filed: 1985-01-08
Abstract: PURPOSE:To prevent the overheat of the wall of a lamp tube and the shortened life of the lamp by mounting a protrusion to the wall portion of the lamp in the opposite side to the cooling wind blow-off direction of a microwave discharging light source device. CONSTITUTION:A protrusion 17 with more than 10mm length is mounted on the wall portion of a lamp tube in the opposite side to a lamp 9 supporting rod 10. The protrusion 17 may be in contact with a cavity wall 7. Cooling wind blown off from a feeding entrance 8 fully cools the feeding entrance 8 side of the lamp, and the opposite side of the entrance 8 is cooled by the thermal conduction from the protrusion 17 mounted on the opposite side of the entrance 8 rather than the cooling wind. Since the protrusion is brought in direct contact with the cavity wall, the heat from the lamp is moved to the cavity wall, and the cooling efficiency can be further improved. If the protrusion 17 has less than 10mm length, the cooling efficiency is insufficient.
