Filed: 1931-06-26
Abstract: 366,859. Vices. LINDNER, H., 57, Fruchtstrasse, Berlin. June 26, 1931, No. 18535. Convention date, July 3, 1930. [Class 61 (ii).] In a vice of the kind comprising two coaxial screw spindles one effecting quick and the other slow jaw movement, the quick pitch spindle is hollow and forms a nut for the slow pitch spindle, rotation of the latter being imparted to the quick pitch spindle by means of a friction clutch and a ratchet device so that the ratchet device moves the clutch only when the jaws are being closed. The slow screw 7 works in the end of the quick screw 6 and has a square part 8 engaging a socket 10 which is square inside to rotate with part 8 and cylindrical outside to rotate within a sleeve 11 bearing at one end against flange 5 of socket 10 and having ratchet teeth at the other end engaging ratchet teeth on a collar 12 slidable on socket 10 against the pressure of a spring 14, but held against rotation thereon by pins 13. Sleeve 11 frictionally engages the base of the quick screw 6 so that during the closing movement of the vice the rotation of slow screw 7 is transmitted through clutch 12 to the quick screw 6 ; as soon as gripping pressure occurs screw 6 is locked by a divided nut device 18, 19, Fig. 2, and sleeve 11 slips within the bore of screw 6, screw 7 rotating in. screw 6 to clamp the work. When the grip is released clutch 12 slips and screw 7 merely rotates within screw 6 until head 9 contacts its end, whereupon screw 6 rotates with screw 7 and effects rapid opening. In the modification, Fig. 5, the clutch device is in the form of a coil spring 11a on the round extension 8 of screw 7.

Title: Improvements in roll film dark slides
IPC: G03B1/48
Filed: 1920-07-07
Abstract: 147,110. Zeiss, C., [Firm of]. Feb. 14, 1918, [Convention date]. Roller slides.-In a roll-film dark-slide, the film in the focal plane is sucked from the back on to a flat plate, and pressed on the front by a frame. The flat plate c, Fig. 2, has a series of grooves c<5> on the surface in communication by channels c<2>, c<4> with suction bellows d which are expanded by springs e connected to the back plate d<2> of the bellows. The channels at the centre of the plates c are the largest and decrease in size towards the circumference. Both frames have a felt strip g. The front frame f is pulled towards the suction plate c by springs f<2> and held in forward position for changing the film by retaining catches f<3>. The film is changed by turning a handle i, Figs. 1 and 3, which indirectly drives the gear-wheel i<2> and the take-up spool b<2>, and two shafts k, l through belt gearing. During the first quarter of the motion of the handle, the spool b<2> is not turned, but the shaft k is rotated, and two eccentric disks k' thereon moves the frame f away from the plate c. During the further rotation, the spool b<2> and shaft l are turned and two rotating arms l<1> on the shaft l engage the back frame d<2>, thereby collapsing the bellows, the frame d<2> being held by spring catches e<1>. After changing the film and before making an exposure, the knob m<7> is pressed. The bellows plate d<2> is thereupon released by a lever m<1> and flexible cords m<2>, m<5> and m<6>. The bellows expand and the film is sucked on the plate c, the stronger suction being at the centre. A projection h<4> on the plate d<2> rocks a spring-arm h<3> and releases the catches f<3> holding the frame f through a bell-crank lever l<2>.

Title: Adjustable Brake Actuating Mechanism
Inventor: KREITNER CHARLES ARTHUR
IPC: F16D55/14
Filed: 1968-04-23
Abstract: 1,182,729. Disc brakes; slack adjusters. LAMBERT BRAKE CORP. 23 April, 1968. No. 19175/68. Heading F2E. In a friction brake which is actuated by pulling a pull-rod 58 relative to the brake housing by movement of a lever 64 pivotally mounted to the housing, wear of the friction surfaces of the brake is automatically compensated by a cam-operated plunger which cooperates with a pawl and ratchet mechanism to advance a nut 74 along a screw-threaded portion 72 of the pull rod to shorten its effective length. When the lever 64 is moved by an hydraulic cylinder 80 to apply the brake, the plunger, which is mounted on the lever, is moved under the action of a spring 108 and causes the pawl to move over the teeth of the ratchet. On release of the brake, the cam surface 116 displaces the plunger against the action of the spring 108 to positively actuate the pawl in a direction tending to rotate the ratchet, the ratchet being moved on by one tooth interval when the lever 64 is displaced sufficiently on application of the brake. In Fig. 5, the pawl 94 is mounted directly on one end of the plunger, the other end of which co-operates with a tapered cam member 114 pivotally mounted on the brake housing. In order to accommodate lateral displacement of the plunger by the ratchet teeth, the member 98 is pivotally mounted on the lever 64, a spring 124 biasing the plunger and pawl into contact with the ratchet. In Fig. 6, the pawl 138 is mounted on a lever 136 pivotally connected to one end of the plunger, the other end of which carries a wheel 112a co-operating with a fixed cam surface 116a integral with the brake housing. Disc brakes. When the rod 58 is pulled on application of the brake, links 52, 54 draw pivots 48, 50 towards each other thereby causing counter rotation of two discs (24) (26) which are mounted back to back and concentric with the shaft 12 to be braked. The mutually facing surfaces of the discs (24) (26) have cam surfaces 32, 34 formed therein which co-operate with captive balls 36 to urge the discs apart when they are rotated thereby forcing friction surfaces (16), (18) into contact with both sides of two brake discs (20), (22). The brake discs (20), (22) have splined internal margins co-operating with complementary splined portions of the shaft 12 to allow axial displacement of the brake discs. Springs 38 cause retraction of the discs (24), (26) when the brake is released.

A device for randomly ejecting an article comprising a housing means 20 having an open top 22, an article supporting means 23 within the housing means adjacent the top, and article ejecting means 30 opemtively engaged by an article B receivable by the article supporting means to eject the same from the housing means, actuating means 84 operatively connected to the article ejecting means for actuating the same, portions of the actuating means being engaged by an article received by the article supporting means to actuate the ejecting means thereby ejecting the article from the housing means, means 36 for rotating the article rejecting means during actuation thereof whereby articles successively received by the article supporting means are ejected in a random radial direction. As shown a piston 30 provided with an inclined top surface 30' serving as an eccentric when the piston is rotated by a turntable 36, is mounted in a depending circular flange 31 below opening 24 of the frusto-conical supporting means 23. A longitudinally extending vertical bore 82 extends through piston 30 and stem 35 and carries a linearly movable pin 84 defining an actuating member the lower end of which normally rests on the free end of arm 81 interiorly of slot 76, the arrangement being such when a golf ball or other article is received in the funnel-shaped member 23 and engages the exposed upper end of the pin 84, a microswitch 78 is closed to actuate the article ejecting means which is defined by a plunger means including the piston 30, stem 35, split piston 75 and solenoid core 71, the arrangement being such that the core 71 and its associated split piston 75 is extended upwardly. The sharp impact of the upper end of split piston 75 against the lower end of stem 35 causes piston 30 to raise to the article ejecting position shown in dotted lines the abrupt upward movement causing the golf ball B to roll out of the funnel-shaped cup member 23 and back onto the ground or green, when the device is inserted in a tubular receptacle (11), (Fig. 1 not shown) positioned in a hole in the ground. After the article has been ejected, the resilience of an arm 80 reopens the microswitch, and upon de-energization of the solenoid coil 69, the plunger means drops by gravity into its normal inoperative position, until the pin is again impacted by another article. Other modifications are described.

Abstract: 596,722. Valve superheterodyne circuits. FORD, D'A. N. Aug. 1, 1945, No. 19733. [Class 40 (v)] A frequency changer comprises a local oscillator operating at the intermediate frequency, and means for modulating the local oscillations in accordance with the modulations on the incoming carrier signals. Carrier signals from input circuit LC are rectified at grid G1 by virtue of circuit C1, R5, to impress the modulation components of the signals on the electron stream in multi-electrode valve V. Grid G4 is associated with anode A in an oscillatory circuit tuned to the intermediate frequency, so that modulated signals at this frequency appear in the anode circuit which includes byepass arrangements for unwanted frequencies. The output may be fed to a similar frequency changer generating a different intermediate frequency or direct to normal I.F. amplifiers. Variable components R1, C3 are amplitude , controls for the local oscillations. Alternatively, the oscillator section may comprise grids G2, G3 and grid G4 may accept the carrier signals. In this case, a differential capacitor may provide the amplitude control and the output transformer may be associated with a tuned circuit in the anode lead, or in the oscillator section with a coupling condenser between the anode and control grid. The rectified carrier signals may be supplied to valve V from a separate detector with or without reaction.
