Title: Improvements relating to mechanism for adjusting the needle lifting cam at each operational position on circular knitting machines
Inventor: SCHMIDT RICHARD
IPC: D04B15/82
Filed: 1960-12-21
Abstract: 965, 442. Knitting machines. FRANZ MORAT G.m.b.H. Dec. 21, 1960, No. 43930/60. Addition to 919,849. Heading D1C. The position of the needle lifting cam (2) of the parent Specification is selected by the use of a stepped slide 39, with steps 0 to III, which act on the slide 27 to position it so that the lever 12 may act on a desired peg 3 to 5. The invention is desscribed in relation to a machine with twenty-four systems and, in Fig. 1, the first (upper) and twentyfourth (lower) systems are shown with a clearing cam 37 nearing the end of one revolution in the twenty-fourth system. The operational sequence is as follows:- The cam 37 acts on the slide 27 and moves it so that a latch 31 drops behind a member 30 to hold the slide 27 inoperative. Pattern mechanism then acts on a drum 145 for the first twelve systems and a drum 146 for the second twelve systems to operate draw wires 42 to set the stepped slides 39 as desired. A cam 34 then releases the latch 31 of the first system to simultaneously allow the slide 27 to be acted on by a cam 36 which lowers it until it contacts the stepped slide 39 to select which of the pegs 3 to 5 is to be raised by the cam 22. Cam 37 then clears the slide 27 to be held inoperative by the latch 31 and the cams proceed to operate at the second system. Selection is made once per revolution after the cam 37 has cleared the twenty-fourth system. Specification 788,730 is referred to.

Abstract: 441,908. Permanent magnets. SHEVLIN, J. T., 15, South Street, Finsbury, London.- (Deuta-Werke Vorm. Deutsche Tachometerwerke Ges. ; 25, Oranienstrasse, Berlin) Feb. 1, 1935, No. 3373. [Class 35] [See also Group XXXVI] An instrument has a moving coil 5 carried by a spindle 8 and enclosing a laminated magnetic core 2, the magnetic circuit of which is completed through laminated poles 1, 3. The laminations forming the core 2 and poles 1, 3 are shaped as shown in Fig. 2 with a circular head having a central hole and a slot 17. The spindle 8 carrying the coil 5 and pointer 11 is mounted between bearing screws 18. The hook ends of the laminations forming the core 2 are then introduced singly into the coil 5, the slots 17 of alternate laminae being preferably arranged on opposite sides of the centre line so as to form a closed annular core for the coil 5. Alternatively all the slots may face in the same direction. The laminae forming the poles 1, 3 may be similarly arranged. The instrument shown in Fig. 1 is for alternating current, the magnet having flat coils 4 mounted between the core 2 and the poles 1, 3. The air gaps 6, 7 between the plates 1, 2, 3 are determined by distance pieces 14, 15, which may be of chrome nickel so as to form a magnetic shunt the permeability of which is dependent on temperature. For direct-current instruments a permanent magnet is formed by replacing the coils 4 by magnetic material of high retentivity. This is used in the form of powder in conjunction with a binder such as shellac or artificial resin and is tamped into the spaces between the plates 1, 2, 3.

Abstract: 1,247,077. Camera exposure control. HATTORI TOKEITEN K.K. Sept.11, 1969 [Sept.24, 1968], No.44898/69. Addition to 1, 246, 868. Heading G2A. The device of the parent Specification is modified in that when subject brightness is below the predetermined value, but a faulty flash, or no flash at all, is connected, the shutter release and the member which sets the camera for flash operation are allowed to couple but are prevented from moving; the coupling being manually overridable to permit a daylight exposure to be made. As shown, for high brightness, transistor T is non-conductive, electromagnet M1 is not energized, level 18 and thus lever 12 remain in the positions shown and the coupling between release 1 and flash-changeover plate 8 is not made. For low brightness, transistor T conducts, electromagnet M1 is energized, levers 18, 12 move, the latter into the path of release 1, and plate 8 is depressed by release 1. If flash device F is working, electromagnet M2 is energized and attracts lever 24 out of the path of plate 8 so that switch S2 is closed, the shutter is released, switch S3 is closed and flash F operated. If device F is not working, electromagnet M2 is not energized and level 24 prevents movement of plate 8. This may be manually over-ridden by a plate 28 which moves lever 12 (or 18) out of the path of release 1. Alternatively, opening a switch S4 de-energizes electromagnet M1 releasing levers 18, 12 and allowing the release to be pressed. Plate 28 may assure three positions viz. overriding, neutral, and release latching.

Abstract: 1,205,950. Hydrostatic transmissions. INTERNATIONAL HARVESTER CO. 10 Oct., 1967, No. 46168/67. Headings F2C and F2D. In a hydrostatic transmission having a variable displacement swash-plate pump connected in closed circuit with a variable displacement swash-plate motor, and hydraulic servomechanisms selectively controlling the pump and motor swash-plate inclinations, an engine driven auxiliary pump 14 having low and high pressure outlets 15, 20 respectively supplies make-up fluid to the power circuit from the outlet 15 at a pressure limited by a relief valve 17 and fluid to the servo-mechanisms from the outlet 20 at a higher pressure limited by a relief valve 22. Make up fluid from the outlet 15 reaches pump and motor kidney-shaped ports 49, 49a, 50, 50a (Fig. 2) via lines 18, 44, 44a and check valves 45, 45a. Cross-connected relief valves 47, 47a relieve overload pressures in the power circuit. Heated fluid from the low pressure side of the power circuit passes via a line 51 or 51a and a spring-centred shuttle valve 52, lines 32, 33, and a relief valve 34 to a cooler 36 and thence via a by-pass control valve 38 and a line 41 to lubrication sprays 42 for the pump and motor or to a relief valve 43 discharging to a sump 10. The three position by-pass valve 38 (Fig. 5, not shown) has a combined valve sleeve and piston (77) moved against a spring (78) by pressure in a by-pass line 37. At low inlet pressures, the by-pass line is closed and all the flow from relief valve 34 passes to the cooler. At a higher pressure, the cooler by-pass line 37 is also opened to the line 41. At a still higher pressure, by-pass line 37 and the cooler outlet are both connected to line 41 and to a drain line 40. The relief valve 22 discharges to a lubricant spray 28 for the pump and motor and to the sump (Fig. 1) or to the low pressure line 16 (Fig. 3, not shown). The servo-fluid supply from outlet 20 passes to the hollow anchor pin 57 of the servo-mechanisms, and enters cylinders 61, 61a through orifices 60b, 60c. Cam-controlled outlets 62, 62a from the cylinders regulate the discharge therefrom and hence the setting of the piston-cylinder combinations to control the pump and motor swash-plate settings.
