Title: Improvements in or relating to interference suppressing circuit arrangements
IPC: H03K3/037
Filed: 1969-03-26
Abstract: 1,208,996. Transistor logic circuits. TELEFUNKEN PATENTVERWERTUNGSG.m.b.H. 26 March, 1969 [23 April, 1968], No. 15845/69. Heading H3T. Two bi-stable circuits FF1, FF2 in cascade between input terminals L, L<SP>1</SP> and output terminals A1, A2 are responsive only to complementary input signals (i.e. 0, 1 or 1, 0), the output at A1, A2 being unchanged by in-phase unidirectional signals (i.e. 0, 0 or 1, 1). Each bi-stable is formed of two cross-coupled NAND gates. If, for example, both L, L<SP>1</SP> become 1, then there is no change in FF1 output; if L, L<SP>1</SP> become 0 then FF1 output becomes 1, 1, and thus FF2 produces no change of output, FF1 returning to the original state when the 0, 0 inputs are replaced by the original complementary input at L, L<SP>1</SP>.

Abstract: 963,806. Inductors. ILLINOIS TOOL WORKS Inc. April 22, 1963 [April 20, 1962], No. 15856/63. Heading HIT. The control rod for adjusting the position of the cone in a tuning coil comprises a rod 30 (Fig. 1) with a flexible hook portion 36, which has a series of stepped shoulders, each facing towards the shaft portion 34 of the rod, on one side, and a smooth, curved surface 42, on the other. The rod may be of nylon, so that the shaft is rigid and the hook portion 36 has enough flexibility. The stepped surface of the hook portion 36 is initially of roughly concave curvature (Fig. 2, not shown) while the smooth side 42 is convex. The hook portion 36, of hexagonal cross-section, complementary to, and of slightly smaller area than, the non-circular bore 26 of the cone 22, can be passed through the bore until the shoulders 38 and 40 abut against opposite ends of the cone, the hook portion flexing so that its axis forms a straight line with that of the shaft 34. For different lengths of the cone 22, a different shoulder 40 abuts against the corresponding end of the cone. Using handle 32, the cone, threaded on its outer surface 24, may be screwed into the tapped, insulating, tubular coil former 10. In an alternative construction (Figs. 5 and 6, not shown), the hook portion is of circular crosssection and fits into a circular bore in the cone, a threaded portion of the shaft of the rod passing through, and co-operating with, a thread-engaging nipple attached to the coil former. The nipple may be screwed on to the threaded handle before being attached to the former.

Title: Improvements in and relating to air ejectors and the like
IPC: F04F5/52
Filed: 1928-05-31
Abstract: 317,924. Hick, Hargreaves, & Co., Ltd., and Arrowsmith, G. May 31, 1928. Aspirating-apparatus, ejector.-In steam or air ejectors, particularly second or subsequent stage ejectors used in series in exhausting a steam condenser, the ejector is stabilized by automatically admitting air to control the vacuum. The control valve c is connected to a float or diaphragm which is subject to the vacuum or pressure prevailing in the ejector and to the atmosphere, or to a torricellian vacuum produced by a barometric device. The valve is provided with an extension d guided by a spider e. The valve and spider are open to the atmosphere and are protected by a cage f. The casing a is divided by a diaphragm g through which passes the spindle h connected to a metal float i in the chamber n. A tube j extends from the casing a into another adjustable tube k the upper end of which terminates in a chamber m. The chambers n, m constitute the vacuum and atmospheric heads of two limbs of a barometric device suitably filled with mercury. The spindle h is provided with a cup member r upon which air impinges when the valve c opens and compensates for variations in the resultant atmospheric pressure on the valve in different positions. Alternatively the ejector may be balanced against a perfect vacuum by closing one limb of the mercury column. An atmosphere-actuated diaphragm may be used in lieu of the mercury column.

Title: A device for closing and opening an electric switch at predetermined times
IPC: G04C23/24
Filed: 1937-06-09
Abstract: 484,949. Time switches. SORENSEN, S. A. June 9, 1937, No. 16062. Convention date, June 9, 1936. [Class 38 (v)] A device, particularly suitable for turning wireless programmes on and off at predetermined times, is operated by pins inserted in two circles of holes on a dial. A pin such as p<1> on a clockwork driven 24 hour dial engages and then releases the end b<1> of a lever B<1>, D<1>, the consequent oscillatory movement of the end D<1> of which causes the release in two steps of a spring-driven disc T which is connected to a switch M by a crank and eccentric mechanism L or other means. The arm D<1> has at its end two abutments one of which, F<1> normally engages a pin s on the disc T. When the pin p<1> engages the sloping end of the arm B<1> the abutment F<1> is slowly moved to the right releasing the disc T which rotates till the pin s engages the second abutment F<2>. When the pin p<1> slips off the end b<1> the lever B<1>, D<1> moves back quickly to its original position releasing the pin s so that the disc T can now rotate to close the switch M. In the form shown the disc rotates only through half a revolution being stopped by the pin s engaging one of two abutments on a second lever B<2>, D<2>. This second lever operates in a similar manner to the first lever B<1>, D<1> when it is oscillated by pins p<2> arranged on a different circle of the same dial. That is, at predetermined times it releases the disc T in two steps so that the disc turns through half a revolution to open the switch M till it is stopped again by the abutment F<1> on the first lever. The switch may also be manually operated by press buttons U<1>, U<2> on arms connected to the two levers. A quick break is given by a spring M<1> and lost motion between the crank wheel K and the disc T. The pins are adapted to be inserted in holes in the dial which are arranged very closely together so that the switch can be turned on and off if desired at small intervals of time, say every five minutes.

Title: Improvements in or relating to machines for the manufacture of glass articles
IPC: C03B9/22
Filed: 1927-06-17
Abstract: 297,340. Hunt, S. June 17, 1927. Blowing.-Relates to machines for making glassware, particularly rotary suction-gathering machines such as those described in Specifications 164,763, 165,453, 165,710, and 165,800, in which cams are used for controlling the movements of the moulds in opposition to spring or other applied pressure or gravity. According to the invention, means are provided for throwing the operative portions of such cams into or out of action, whether the machine is working or not, and preferably by means under the control of the machine minder. In the construction shown in Fig. 2, a cam 11, fixed to the central column of a rotary machine, engages rollers 18 secured to the levers of the parison moulds and lowers the moulds to the gathering-position, the moulds being normally kept in the raised position by means of counterweights. The cam has a humped portion 10 which effects the lowering of the moulds, and this portion is made as an in. dependent section which can be lowered when desired. When lowered, the rollers 18 ride over the section and the moulds are not dropped as they pass the gathering-point. Further, if the machine is stopped while a mould is dipping into the molten glass, the section 10 can be lowered to raise the mould out of the glass, and the machine can be drawn back without the mould fouling the edge of the gathering-tank. The device can be interconnected with the traversing gear of the machine in order to prevent the machine from being moved back until the section 10 is lowered.

Title: Improvements in and relating to mixing and agitating machines
IPC: B01F7/00
Filed: 1953-06-15
Abstract: 734,636. Mixing appliances. WADHAM, H., and TORRANCE & SONS, Ltd. June 15, 1953, No. 16479/53. Class 86. A mixing machine has a stirrer arranged for a combined bodily sweeping movement and axial rotational movement which will differentially vary automatically according to the loads encountered in making said movements. The stirrer 6 is fast with a planet gear 4 carried by an arm 5 which is free to rotate about the axis of a sun gear 3 which is in direct mesh with the planet gear 4. The sun gear 3 is fast with a driving shaft 2. If the resistance to axial rotational movement of the stirrer increases relatively to the resistance to orbital sweeping movement of the stirrer, the axial rotational movement slows down and the orbital sweeping movement speeds up, and vice versa. The arm 5 may carry a scraper, Fig. 2 (not shown), for the container wall 12. To facilitate charging of the container without stopping the machine and to permit localized treatment of material by axial rotational movement only of the stirrer, the arm 5 carries a brake ring 8 against which a brake block, Fig. 2 (not shown), may be applied to arrest the orbital sweeping motion of the stirrer whilst allowing its axial rotation to continue. A deflecting head 11 on the stirrer directs material rising up the stirrer back into the container.

Title: Sewing machines
IPC: D05B19/00
Filed: 1919-07-02
Abstract: 152,077. Fairweather, W., (Singer Manufacturing Co.). July 2, 1919. Sewing - machines; needles, vibrating laterally; lock-stitching by shuttles.-In a machine for producing zigzag stitching containing a plurality of stitches in each limb of the zigzag and in which the shuttle oscillates in the plane of vibration of the needle, mechanism is provided for moving the shuttle bodily and/or for accelerating or retarding its oscillation in order that its beak may register properly with the needle loop in the laterally displaced positions of the needle. The needle bar 5 is reciprocated in guides 26 by a member 29 guided for vertical' movement and actuated through a link 30 by a crank-pinion the disk 4 carried by the main shaft. To vibrate the needle laterally, the guides 26, which carry horizontal projections mounted to slide in the head D, are connected by link:; 39, 40 with arms 38 of a shaft 36 rocked by the lever 44 through the crank 42 and link 43. The lever 44 is vibrated by a rod 46 connected to a block 55 adjustable, to vary the amplitude of needle vibration, along a link 53 pivoted at 54 and carrying at 52 a roll engaging a pattern cam 51 in the wheel 45. For straightaway stitching, the block 55 is clamped at 54 to the link 53 whereby no movement is imparted to the lever 44. The means for accelerating or retarding the shuttle are as follows : The shuttle driver 75 carried on the shaft 76 is oscillated from the rocking shaft 68, shown in underside plan, Fig. 3, by means of bevel wheels 77, 77<x> and a shaft 78 which carries a pinion meshing with a pinion 80 mounted on a sliding sleeve 81 having a pin and inclined slot connexion with a sleeve 82 fast on the shaft 68. Sliding movement is imparted to the sleeve 81 by a link 88- connected to the arm 87 of a rock-shaft 86, the arm 85 of which is connected by a link 84 to the arm 44<x> of the lever 44. In order to move the shuttle bodily, the arm 87 is also connected by a link 90 to a frame 73 mounted to slide on a rod 74 and carrying the shuttle raceway 72. When the lateral vibrations of the needle are of relatively small extent, the links 39, 40 may be connected to the arms 38 at Z, in which case either the accelerating or the bodily movement of the shuttle may be dispensed with by disconnecting either the link 88 or the link 90. In order that the needle thread may reeve easily round the shuttle thread, a pin 91, Fig. 10, on the shuttle driver 75 engages the shuttle thread on each retnrn oscillation of the driver and positions it for pulling correctly into the work, when the needle is displaced toward the beak of the shuttle. Presser-bars.-The presser-bar 7 is carried by a spring 15 and is lifted by a handle 25 that operates a toggle connected to the collar 19 on the spring.
