Title: Improvements relating to slicing machines
IPC: B26D7/32
Filed: 1928-02-14
Abstract: 306,280. Fitzpatrick, H. D., (Maatschappij t'ot Vervaardiging van Snijmachines Volgens van Berkel's Patent en van Andere Werktuigen). Feb. 14, 1928. Cutting slices in succession. -In a slicing machine, the slices as they are cut are received by a suction device which conveys them through a right angle, or substantially a right angle, and deposits them. Fig. 3 shows a suction device suitable for use with a disc knife reciprocating table machine in which the knife is in a vertical plane, the device consisting of an outer plate 22, comprising part of a frustum of a cone, and a segmental plate 23 secured thereto to form a chamber 25, a part of the surface of the plate 22 having perforations 28. The device is mounted on a shaft 21 the axis of which bisects the angle between the cutting plane and the slice receiving table, so that the slices are received in a vertical position and deposited in a horizontal position. The device is oscillated by a rack on the reciprocating table engaging a gear wheel 32 on the shaft 21, and the surface speed of the plate 22 may be greater than the cutting speed to stretch the slice and prevent the formation of wrinkles. The suction pump may be of any type, driven from a rotary or reciprocating part of the machine, or driven independently. The pipe 31 connects the pump with the chamber 25, the shaft 21 having a central passage 27 with a lateral port 30 at its bottom end which registers, when a slice is being cut, with the suction passage 31. and, when a slice is to be deposited in the horizontal position, with a lateral passage in the foot step bearing 20, open to the atmosphere, the vacuum in the space 25 thus being broken. The space 25 is connected with the passage 27 by radial passages 26. A guard plate prevents oil from the gear wheel 32 from reaching the deposited slices. The suction device may rotate instead of oscillate.

Title: Improvements in and relating to warp beam brakes in weaving looms
IPC: D03D49/08
Filed: 1950-02-27
Abstract: 668,586. Letting off warps in looms. BARZAGHI, A. Feb. 27, 1950 [Feb. 25, 1949], No. 4986/50. Class 142(ii) A chain or rope 4 anchored at one end is wrapped round a warp beam ruffle 3 and connected through a tensioning device to a further chain or rope 12 secured to a pulley 13 fixed to a floating shaft 15. A roller 5 acting as a feeler is pivoted in the end of an arm 8 pivoted to an arm 14<SP>1</SP> carried by a hub 14 on shaft 15, an adjustable compression spring 9 being interposed between the arm 14' and a hand-wheel'10 and a rod acting on the arm 14. An L-shaped lever 17, 17<SP>1</SP> pivoted at a fixed point 18 is pivoted to the shaft 15 at one end and at the other end is secured to a rod 20 carrying a compression spring 23. Loosening of the ruffle chain caused by movement of the feeler is compensated by the downward pressure on the shaft 15 from the spring 23 acting through the L-shaped lever. The mechanism is duplicated at the other end of the beam, the shaft 15 being common to both. In the embodiment shown in Fig. 4, a feeler 7 is secured to a shaft 11 which is carried by arms 12 pivoted to brackets 8<SP>11</SP> on supports 6 hung on the beam shaft 4 at each end of the loom. At each end a ruffle .chain 17 is secured to the shaft 11 and a further shaft 13 in the supports 6. A compression spring in a box 8 operates directly on the shaft 11. Small oscillations of the brake end beam are braked by an ajustable spring 15" through a rod 15 and an arm 9 secured to the shaft 11.

Title: Cyclic Monitoring System for Electrical Devices
Inventor: HALL JAMES ROBERT
IPC: G08B23/00
Filed: 1966-02-04
Abstract: 1,174,091. Selective signalling. COAL INDUSTRY (PATENTS) Ltd. 3 Feb., 1967 [4 Feb., 1966], No. 5022/66. Heading G4H. A plurality of remote switch units, each including a single switch (e.g. along the face of a coal mine) are scanned cyclically and repeatedly, operation of any switch, or the occurrence of a fault, terminating each scan prematurely and turning-off a motor. The position at which the premature termination occurred is indicated centrally by lamps. The switch units, which comprise principally a transistor, a Zener diode and manually operated switch contacts, and which function as monostable circuits are so arranged that when all the switches are unoperated, they are connected in series. The application of a pulse to the first switch unit in the series then turns it " on " and after a short time it reverts to its stable condition and in so doing turns on the next switch unit, and so on until the end of the chain is reached. Each time a switch unit reverts to its stable state a pulse travels back via the series connected units to the central equipment where it is counted. At the end of a scan cycle one pulse will have been produced by every switch unit and a count equal to the number of switch units indicates that no switch count has been operated manually and that no fault has developed. Under these circumstances the motor control circuit is energized. If, however, any switch count is manually operated, then the series connection between it and the next switch unit is broken, and also its time constant is increased by a factor of about six. Thus a scan of the switch units will now terminate prematurely at the manually operated switch and the number of pulses counted will indicate its position. Also the last pulse received was a certain period later than usual. In these circumstances the motor control circuit is not energized. If a fault occurs which prematurely terminates a scan, the count reached will indicate its location and the fact that the last pulse to be counted was not a particular period later than the previous pulse will indicate that a fault has occurred. A fault indication is then given.

A machine for making slotted head screws has a holder which rotatably supports a screw and presents its head to a rotatably mounted screwdriver which turns the screw so that any burr at the end of the slot is sheared off against the holder. A single-spindle automatic screw machine has a hardened slotted bush, which receives the parted-off screw, and which is mounted at the end of an arm 1 which is mounted on a shaft 13 for rotary and axial movement. The arm swings through 90 degrees after receiving the screw and presents the screw head to a circular saw (7), Fig. 2 (not shown) which slots the head. In its return movement to its initial position the arm stops at an intermediate position at which the screw is pressed against a screwdriver head 17 which is rotated by a connecting rod 23 and a follower arm 26 which is oscillated by a cam 27. A spring loaded cap 29 surrounds the screwdriver head and is pushed back as the arm 1 moves the screw towards the screwdriver, which engages the slot and turns the screw head in the bush to shear off any burr produced by the slotting saw.

Abstract: 926,558. Control of D.C. motors. A. K. LITTWIN. Feb. 13, 1961, No. 5296/61. Class 38 (3). The work-table of a machine tool is recipro. cated by an electric motor which is controlled by a cam on the table engaging a lever arm 26 associated with transformer cores 38, 40. Movement of the table rocks a bar 36 so that an increased voltage is induced in secondary winding 32s to fire a valve 52. An associated valve 56 is fired to energize relay 62 and reverse the motor. This movement of the table lowers the core 40 into the coils of transformer 34, whilst the core 38 is withdrawn from coils 32. This fires the valve 54 followed by firing of valve 58 to energize relay 64, whereby the motor is again reversed. The range of movement of the table is adjusted by means of potentiometers 48, 50, and such adjustment may be made while the table is moving. The relays 62, 64, control contactors in the motor circuit, such contactors being each provided with a holding circuit for continuing movement of the table until the table is reversed by the switch at the opposite end. An armature resistance is connected in circuit as the table approaches its end-positions. The adjusting members for the potentiometers 48, 50 are interlocked so that neither becomes effective, until the table is beyond the control of the other, the minimum working range of the table being shiftable along the maximum range of operation of the table. In another arrangement, the potentiometers are replaced by further transformers having manually positioned cores, Fig. 8 (not shown). The table may be driven by a non-electric motor having an  electrical control circuit.
