Title: Hydraulic power transmission apparatus particularly for motor vehicles
IPC: F16H43/00
Filed: 1937-07-16
Abstract: 504,175. Reciprocating pumps. KRUSE, W. July 16, 1937. Nos. 19749 and 19750. Convention dates, July 17, 1936 and March 24, 1937. [Class 102 (i)] [Also in Group XXIX] In a hydraulic power transunitter, liquid is transferred from space 16 to space 12 by a make-up pump, the cylinder of which is carried by the driven element, and the piston 18 of which is reciprocated by contact with a cam disc 20 on the driving shaft. Delivery is past a valve 44, and when the pressure in space 56 is excessive, a member 21 is operated against a spring 22 to hold the piston 18 away from the disc so as to render the pump inoperative, If the driven member over-runs the driving shaft, a notch in the cam disc 20 engages a pin in the driven member, so that the parts are temporalily coupled mechanically.

Abstract: 148,352. Hupfeld Akt.-Ges., L., (Assignees of Salzmann, B.). March 11, 1918, [Convention date]. Recording music.- In the production of perforated tune-sheets, the expression employed by an operator of an automatic piano is automatically recorded in full on a second tune-sheet, the expression perforations being subsequently inserted in the latter on the basis of the automatic record. A tune-sheet f, already perforated for notes, is driven synchronously with a similar sheet e which controls the automatic piano, and the operator's foot-actuation of the bellows c of the instrument is recorded as a curve on the sheet f either directly, or by pneumatic means such as a bellows g, or a manometer, in communication with the bellows c and operating a pencil or marking-wheel h mounted in a guide i parallel to the tune-sheet roll. The operator's actuation of each of the five hand-stops (controlling treble and bass throttle, treble and bass hammer rest rail, and dampers) and the tempo-lever, is recorded in broken lines by electro-magnetic means with pneumatic transmission, as in note-recording. Specification 964/12, [Class 88 (i), Musical instruments, Automatic], is referred to.

Patent GB-261100-A (GB)
Title: Improvements relating to weighing machines and mechanism connected therewith
IPC: G01G21/00
Filed: 1925-08-14
Abstract: 261,100. Avery, Ltd., W. & T., and Bradley, L. C. Aug. 14, 1925. Apparatus fitted to barrel-filling devices.-In a weighing-machine of the kind wherein the tare of an empty barrel or other container may be compensated for and the indicating pointer brought back to zero so that an indication of the net weight of the liquid or other commodity introduced into the barrel may then be obtained, mechanism is provided for controlling the supply of liquid &c, so that the supply-control means can only be effectively operated to supply the liquid when the indicator is at zero. As shown in Fig. 1, the indicating spindle 9 of a known form of weighing mechanism carries a flanged disc 10 which, in the zero position, presents a gap 10<b> towards a peg 11 projecting from an arm 12 pivoted within a yoke 13 carried by a lever 14. The lever 14 is pivoted on a pin 15 and is actuated by a crank arm 16 on a shaft 18. The barrel is filled from a supply cock 49 by depressing a handle 44 but this movement is prevented (unless a handle 25 has previously been rotated) by a link 43 connected to a ratchet wheel 38 which is locked by one of a series of oppositely-directed pawls pivoted on the casing. On turning the handle 25 in a counter-clockwise direction its shaft 23 is rotated and the shaft 18 follows the rotation under spring action; if the pin 11 passes through the gap 10<b> the shaft 18 rotates sufficiently to rock a shaft 52 carrying a catch 51, Fig. 2. The catch 51 thus frees a quadrant 28 connected to the shaft 23 by a spring 30. The handle 25 (which engages the quadrant by means of a projection 27) may then be further rotated so that a cam on the shaft 23 liberates the requisite looking pawls of the ratchet wheel 38. The handle 44 may now be depressed to open the supply cock 49 and allow the barrel to fill. A throw-over spring 50 accelerates the movement of the handle. The return of the handle 44 is prevented by the locking pawls of the ratchet wheel 38 until the pawls have been released by the return of the handle 25. The return of the handle 25 restores the arm 12 and its projecting peg 11 to the position shown in Fig. 1, the arm 12 being moved laterally by a cam plate during the return to allow the peg 11 to clear the flange of the disc 10. The movement of the quadrant 28 is frictionally retarded by a spring-pressed plate 32.

The screw may be internally cooled (see Fig. 7, not shown) and the depth of the groove may decrease from the inlet to the outlet end. There may be axial by-pass grooves 14 formed on the inner surface of the tapered portion of the barrel and the larger diameter portion may have knurled helical grooves 12 of opposite hand to that of the screw flight. The roughness 'of the screw and barrel may be different and their roughness may decrease from the inlet to the outlet where there may be a breaker plate or die to create back presesure. The by-passes may be formed as recesses in the periphery of the screw flight or as apertures through the flight and may be semicircular, circular or elongated (see Figs. 8-24, not shown); the thickness of the flight may be increased along one edge of the recesses (see Figs. 16-18, not shown) or the screw flight may have other projections (see Figs. 19 and 20 not shown). The ratio of the depth of the by-passes to that of the flight is 0.2 to 0.9; they form 1% to 20% of the area of the screw threads on the tapered portion of the flight, the apex angle of the tapered portion of the barrel being 2-12.

Abstract: 384,241. Baling-presses clutches. ABELE, H., 298, Seestrasse, Zurich, Switzerland. July 21, 1932, No. 20636. [Class 94 (i).] A baling or bundling press for newspapers comprises stationary blocks 2 and vertically movable press plates 4 on rods 3. A spider 5 carrying the rods is attached to one stretch of an endless chain, the other stretch carrying a counterweight 20. The chain is driven by a sprocket 11 adapted to be clutched to a shaft 9. In use, the sprocket is declutched and the counterweight lifts the plates to the top position. The material is placed on the blocks 2 and the sprocket is engaged by a friction clutch to draw down the press plates and to compress the bundle. The clutch is allowed to slip while the bundle is tied, and is then released. The clutch is shown in Figs. 3 and 5, and comprises a member 23 keyed to a constantly rotating shaft 9 and a corresponding member 30 feathered for axial movement. Between the members, the sprocket wheel 11 for driving the press is mounted on two flanged discs 21 enclosing plates 25 feathered on the shaft. Rings 26 carrying friction elements 27 and connected to the flanges of the discs, are interposed between the plates 25. In use, a spring 13, bearing on a collar 32, keeps the parts in engagement. The actuating lever 14 carries a fork for disengaging the members 11, 21 from the member 23, and, when this has been effected, the axial movement of the members 11, 21 is checked to allow of their disengagement from the member 30.

Abstract: 1418903 Electromagnets LUCAS ELECTRICAL CO Ltd 24 April 1973 [3 May 1972] 20679/72 Heading H1P [Also in Division H2] A magnetic pole for electromagnetic excitation comprises a body 12 (Fig. 1) with an integral shoe 13 of greater width, formed from a single mild steel strip which is corrugated and longitudinally compressed so that the convolutions are in facial contact to define a stack; the lengths of the corrugations adjacent one end being greater than these adjacent the other so that the shoe 13 and body 12 are defined on compression. In a modification a part of the pole shoe is displaced in the direction of the pole depth by correspondingly shaping the strip adjacent the end from which the pole shoe is formed. (Fig. 2, not shown). For use in the interior of the cylindrical yoke of a dynamoelectric machine the pies are formed to have a part cylindrical profile. In an electromagnet, the poles are diametrically positioned within a cylindrical magnetizable yoke 15 (Fig. 3) so that the shoes define a part cylindrical surface through which a shaft extends axially to slidably carry an armature, while the yoke or poles carry an exciting winding. On energization the armature is moved axially along the shaft towards the shoes. The pull on the armature may be positionally graduated by stepping the pole shoes.
