Machines with work-benders.-In a machine as claimed in the parent Specification the presser-foot consists of a plate-like body 17 rigidly fixed to the machine head and having the loop-catcher 23, formed separately, fixed to its upper face. In the embodiment shown, the loopcatcher is spaced from the face of the foot 17 by a plate of thickness similar to that of the thread, and carries a thread-deflecting pin 24, with its lower part inclined towards the needle-path, to engage the upper limb of the thread loop carried by the looper 13, thus spreading the loop somewhat and also preventing the loop from being pulled off the looper as the work is withdrawn in the direction of feed, so that in this event the loop is ruptured; the lower limb of the loop is guided beneath the loop-catcher 23 by a bevelled under-surface on a plate 20 projecting into the area of the slot 17d, Fig. 4, which accommodates the work-bender and feed-dog. The needle is guided by curved upper surfaces of the plate 20 and a plate 19, these plates conforming to the needle path and being recessed into the rear part of the presser-foot, by a wall 17e on the foot, and by the edge of a guide-plate 21 fixed ever the plate 20. The looper 13 is mounted on a spindle 15, Fig. 2, which is inclined both to the plane of the needle-path and to a vertical plane lying in the line of feed, and is actuated by a toothed segment 12 on the tail of the needle-carrying arm on the main shaft 6 engaging a bevel gear on the upper end of the spindle. The work-bender has a stepped upper edge and is displaceable in its holder to bring the higher part into operation for through-stitching; its casing 27 is pivotally mounted and spring- pressed upwards to bring a lug thereon against the conical end of an adjusting screw 32 to provide for different thicknesses of work.

Abstract: 758,101. Radio navigation. STANDARD TELEPHONES & CABLES, Ltd. Nov. 13, 1953 [Nov. 20, 1952], No. 31594/53. Class 40 (7). Relates to an equi-signal glide-path beacon of the type disclosed in Specification 590,491, in which a carrier from an R.F. source 7, Fig. 4, is modulated at 90 and 150 c/s. in modulators 8 and 9, the outputs from which are applied via a conjugate. bridge 11 to aerials A and B spaced H and H/2 above the ground such that the 90 c/s. sidebands are applied in phase to A and B and the 150 c/s. sidebands are applied in phase opposition to A and B, the carrier being applied to 13 only. The vertical radiation patterns 1 and 2, Fig. 1, of serials A and B are such that the resultant 90 c/s. and 150 c/s. sideband patterns define an equi-signal glide-path at an angle 1# corresponding to the first null of the radiation pattern 1 of the upper aerial A. Between 1# and 3# the " fly down " 150 c/s. signal predominates but there is a null at 2# and according to the present invention the gap is filled by radiating an additional 150 c/s. signal with a radiation pattern 6, Fig. 3, which has a maximum at 2# and a null at 1#. As shown in Fig. 4, the additional signal is produced by applying the carrier and 150 c/s. sidebands in phase opposition to aerials C and D via an amplitude adjunta 15, the vertical heights of aerials C and D being 2H/3 and H/3 and their radiation patterns being as shown by curves 4 and 5 in Fig. 2. In order to minimize interaction between the main and auxiliary 150 c/s. sideband signals in the vicinity of the glide-path angle 1#, the signals applied to aerials C and D are in phase quadrature with those applied to aerials A and B.

Abstract: 410,139. Supplying liquid fuel;. regulating. BENDIX AVIATION CORPORATION, 401, Bendix Drive, South Bend, Indiana, U.S.A. Nov. 11, 1932, No. 31921. Convention date, March 8. [Classes 7 (iii) and 7 (vi).] The amount of fuel per stroke injected from a source under constant pressure is controlled in accordance with the pressure in the air-inlet manifold, but is otherwise made independent of engine speed. The fuel, for example gasolene, passes a valve 23, Fig. 8, adjustable by a hand-actuated cam 24, and enters an annular chamber 20, from which it is distributed to the cylinders by valves 26, Fig. 7, and conduits 2. The valves 26 are opened by a rotating cam 34, 36, the throw of which, and therefore the opening of the valves, is varied by adjustment of the part 34 by an axially movable cone 42 connected to a centrifugal governor 43. The governor spring 46 is adjustable by means of a cam 48 connected by linkwork 49, 50, 51 to a diaphragm 55, the upper side of which is connected to the air-inlet manifold, and the lower side subjected to atmospheric pressure at ground level. By this means, the amount of fuel injected is regulated in accordance with the density of the air charge, while the centrifugal governor maintains the volume of fuel injected constant for any particular air pressure, whatever may be the speed of the engine. The injection valve 10, Fig. 5, is opened by the fuel pressure, the fuel entering in the form of a fine conical spray which is further atomized by a deflector 14. Alternatively, the diaphragm 55 may actuate the adjusting-cam 24, and the cam 48 be hand-controlled. Also the cam 24 may be connected to the throttle in the air inlet. The gasolene may be supplied by a pump fitted with a pressure regulator, or by reservoir fed by a pump and placed under pressure by air from the supply used for the starter, brakes, shock-absorbers, &c.

Title: Improvements in or relating to devices for regulating the size of a loop formed by the deflection of a travelling wire, strip or the like material
IPC: G05D15/01
Filed: 1954-11-08
Abstract: 759,448. Automatic control systems. SIEMENS - SCHUCKERTWERKE AKT.- GES. Nov. 8,1954 [Nov. 7, 1953], No. 32326/54. Class 38 (4). In a system in which the sag of a loop of wire or strip material passing between successive rollers is maintained constant by controlling the speed of the rollers in accordance with an electrical capacity variable with sag, a differential capacity variation is utilized to minimize the effects of variation in the cross-section of the material and lateral movement of the loop. In Fig. 2, a travelling wire 30 in a rolling mill hangs in a trough 39 so that it is normally symmetrical relative to electrode pairs 31, 32 and 33, 34. Oscillators 35 and 36 are respectively associated with the capacities formed between each electrode pair and earthed wire 30 so that variation of sag influences the oscillators differentially. The opposite effects on the two oscillators are, however, arranged to be additive in a thermionic or magnetic amplifier 37 which produces a direct voltage dependent in magnitude and polarity on the magnitude and sense of sag variation. The electrodes are coated with ceramic material to prevent electrical contact with the wire. The required amount of sag is set by adjustment of the position of the electrodes or by electrical adjustment of the oscillators and amplifier. Hinged electrodes or electrodes shielded against mechanical damage are referred to. In a modification, Fig. 3 (not shown), each pair of electrodes is connected to two terminals of each oscillator and a strip of earthed conductive material or of insulating material such as paper, rubber or plastic normally runs symmetrically between them. In the case of the insulating strip earth connections are dispensed with and the capacity variations are due to dielectric changes. In a further modification, Fig. 4 (not shown), the loop is supported on a horizontal or slightly inclined platform in which are embedded two electrodes, one connected to each oscillator. The shape or angle of inclination of the electrodes may be arranged to produce a voltage varying with sag according to a desired characteristic.
