Title: A combined dovetail and bumper for doors
IPC: B60J1/00
Filed: 1932-07-07
Abstract: 393,104. Door-stops; rattling and sagging, preventing. TERNSTEDT MANUFACTURING CO., 6307, West Fort Street, Detroit, Michigan, U.S.A.-(Assignees of Haskins, H. B.; 170, Moss Avenue, Highland Park, and Simpson, E. G.; 19415, Argyle Crescent Drive, both in Detroit, Michigan, U.S.A.) July 7, 1932, No. 19187. Convention date, July 8, 1931. [Class 65 (i).] In a door-stop comprising interengaging male and female members mounted on the door and door post, one of the members is yieldingly cushioned for up and down movement relative to the other, and the members are shaped to fit together without one gripping the other ; one of the members is preferably movable inwardly and outwardly and is yieldably cushioned for inward movement. In the construction shown in Fig. 4, a socket member 6 has projecting parts 9 which slidably engage the inside of cups 10 filled with rubber, these cups being slidable in a casing 13 on the door post against the action of springs 14 ; a rigid wedge-shaped member, which may be formed of sheet metal, is fixed to the edge of the door and is shaped to fit easily in the aperture 7 of the socket member 6. The motion of the door is buffered by the springs 14, which then act to press the latch of the door against its striking-plate to prevent rattle ; the springs 14 also thrust the door outwardly when the latch is released to commence opening it. If the wedge member on the door and the socket member 6 are out of alignment the wedge member will engage one side of the aperture 7 in the socket member and the door will be raised to its correct position ; any relative motion between door and frame, such as may occur in a vehicle, is permitted and cushioned by the rubber in cups 10, and no strain is placed on the hinges. The socket member 6 may tilt slightly, against the action of the rubber in the cups 10, to receive the door wedge member properly. In a modification, the socket is formed of two members 25, 26; Fig. 14, which have notched ends for sliding engagement with inturned parts 31 of the casing and have a projection and recess at 32 providing pivotal engagement ; the projection and recess 32 ensure that both socket members move together even if the striking member on the door engages only one of them, to avoid jamming. Springs 35 are provided for cushioning inward movement of the socket members. The wedge member on the door, shown, in section in Fig. 17, is formed of a sheet metal surface member 24 mounted on a block of compressed rubber moulded about a flange 21 on its attachment plate ; the wedge member thus provides the vertical cushioning in this case.

Title: Device for pulling off a teat cup cluster from an udder
IPC: A01J5/04
Filed: 1973-04-25
Abstract: 1397693 Teat cup cluster removal ALFA LAVAL AB 25 April 1973 [3 May 1972] 19666/73 Heading AIM To prevent injury to teats and spillage of milk when teat cup clusters are removed, a cluster removal means 25 is coupled to an air valve 17 in a milk claw to automatically open the valve and reduce the vacuum in reference to the operation of the removal means 25 which may be nuliated automatically or manually by reduced milk flow. The milking claw 1 has an air inlet channel 16 which is normally closed by valve 17 under the influence of the milking vacuum and a spring 18. When the milk flow is substantially reduced vacuum is applied either manually or automatically to cylinder 25, causing piston 23 to rise and lift valve 17, permitting air to enter claw 1 through channel 16 and flush away the milk in the claw 1 and in hose 4 attached to nipple 5 in the lower half of the claw, simultaneously reducing the vacuum on teat cups 11 thus loosening and finally releasing them. When the cups fall from the teats, air enters claw 1 through hoses 13, removing the vacuum and allowing valve 7 to shut off nipple 5. Continuing rise of piston 23 raises claw 1.

Title: Improvements in or relating to method of treating polyethylene plastics preparatory to printing
IPC: B29C59/08
Filed: 1951-08-21
Abstract: <PICT:0718715/IV (a)/1> Polyethylene is treated to make it receptive to printing inks by directing a flame across its surface for a short time which is insufficient to cause distortion of the material.  In one form of apparatus for carrying out the treatment, the polyethylene 27 passes over a continuously rotating roller 23 and is subjected to the action of a flame from a pipe 24.  The roller 23 dips into a vessel 25 containing water or other cooling liquid, a film of which is formed on the roller and prevents air pockets underneath the polyethylene where it passes over the roller, in addition to cooling its underside.  The peripheral speed of the roller 23 may be slightly greater than that of the material 27.  A blade 35 removes any water adhering to the polyethylene, prior to the material passing over a vacuum drying roller 31 and thence to a winding drum 33.  The treatment may be applied to the surface of polyethylene-coated electric cable or the surface of bottles or containers made of polyethylene.

Title: Improvements in hydraulic power transmissions and the control of hydraulic motors
Inventor: PEARSON ROBERT COLIN
IPC: F16H61/472
Filed: 1962-05-22
Abstract: 973,018. Hydraulic transmission of power. R. C. PEARSON. March 26, 1963 [May 22, 1962], No. 19693/62. Headings F2C and F2D. [Also in Division G3] A variable displacement hydraulic motor 6 is driven by a fluid at constant pressure from a pump 1. The motor 6 drives a pump 9 which delivers fluid to a line 17<SP>2</SP> or draws fluid from the line 17<SP>2</SP> depending on the direction of rotation of the motor; at a rate proportional to the speed of the motor. A branch 60 leads from the conduit 17<SP>2</SP> to one side of a motor displacement actuator piston 61, the other side of the piston being connected to a line 38. The piston may also be spring-loaded. The conduit 17<SP>2</SP> is connected to a conduit 17<SP>1</SP> containing a manually adjustable flow setting means 16, which may be a valve 80 actuated by a lever 50 or may be a variable displacement pump. The valve 80 is set to the required position to determine flow through the valve from a supply to the line 17<SP>1</SP> or from the line 17<SP>1</SP> to exhaust, depending on the direction of rotation of the motor 6, whereby when the flow from the pump 9 varies from the set flow through the device 16, the resultant change in pressure in the branch 60 causes movement of the piston 61 to vary the motor displacement until the speed changes to provide equal flow through the pump 9 and the device 16. The embodiment shown also provides for adjustment of the flow through the device 16 with the variation of the displacement and hence the load on the motor. The piston 61 is connected to a cam 202 whose faces adjust the loading of valves 209, 309 with movement of the piston. The valve 209 controls the pressure of fluid in a line 207 acting on the end of a valve 212 in the line 17<SP>1</SP> and the valve 309 controls the pressure of the fluid in line 307 which acts on a piston 328 of a valve 312. The valve 312 controls the flow of fluid from an inlet 320 to an outlet 321 which leads to the valve device 16 and the pressure at the outlet 321 acts in a chamber 324 on the right-hand side of the valve 312 to oppose the pressure acting on the piston 328 and that from port 84 of valve 16 acting on piston 326. The valves provide a reduced pressure drop across the valve 16 with increased load on the motor 6 to reduce the speed of the motor. One pump 1 may supply several motors 6 each having a separate speed control as above. In a further modification the branch 60 is connected to one side of a servomotor which positions a valve to control the supply and exhaust to the opposite sides of the piston 61, a lever feedback being provided between the piston and valve.

Title: Photographic camera
IPC: G03B19/04
Filed: 1971-06-09
Abstract: 1313617 Collapsible cameras FRANKE & HEIDECKE GmbH 9 June 1971 [10 June 1970 (2)] 19740/71 Heading G2A A camera has a lens tube 2 which can be moved out of the camera to a picture-taking position, and which can be locked in this extended position; a seperate actuating member controls both the movement and the locking means. All the essential parts are on the main body section 1, on which the part 4 slides telescopically from the operative position of Fig. 1 to the closed and inoperative position of Fig. 3 (not shown). The lens aperture 6 has a covering disc 7 Fig. 4, which is moved away from the lens as the part 4 slides to the operative position. During this sliding movement a lug 17 fixed on part 4 moves to the left and engages a lever 16 to pivot it clockwise. Lever 16 in turn engages another lever 13 to pivot it also clockwise against the action of a restoring spring 15. A toothed segment on lever 13 engages with a toothed segment on a further lever 12 to rotate it anti-clockwise, so that a lever 10, which is fixed to lever 12 and also linked to disc 7, draws disc 7 to the right, so uncovering the lens aperture. After the position of Fig. 5 (not shown) has been reached, lever 16 no longer engages lever 13, and continued sliding of part 4 now causes the lens tube to be extended to the taking position. The movement of the lens tube 2 is guided by lugs 20 on tube which move in slots 21. During the above-described movement of part 4 from the closed position Fig. 9, (not shown) to the operative position of Fig. 7, the lug 17 moves a rod 23 to the left. This pivots a lever 26 clockwise, which moves a linked rod 28 to the right, the other end of the lever being linked to a lever 29 which is hence pivoted clockwise. A forked end 32 of lever 29 embraces the lug 20, and moves it upwards from the Fig. 9 (not shown) position to the Fig. 7 position, thus moving the lens tube from the retracted position to the extended (operative) position. In this position the end 37 of a lever 35, biased anti-clockwise by a spring 38, engages behind lug 20 and locks the lens tube in the extended position. When part 4 is pushed to the right Fig. 1 to retract the lens tube and close the camera, all these movements are reversed. Lever 29 is pivoted anti-clockwise, and an extension 33 engages a pin 34 on the locking lever 29, and so pivots its end 37 out of engagement with lug 20, thus allowing the lens tube to move downwards as shown in Fig.7, i.e. to be retracted into the camera.

Abstract: 389,536. Discharge apparatus. SCHALLREUTER, W. L. W., 73, Cambridge Terrace, Hyde Park, London. April 11, 1932, No. 19767/31. [Class 39 (i).] A gas-filled discharge tube, such as a lamp, is started by forming an ionizing discharge between a main electrode and an auxiliary electrode within the envelope by means of a separate condenser, which is in a circuit connecting the two electrodes and is charged through a series resistance or impedance ; or two auxiliary' electrodes may be used for the ionizing discharge, the main electrodes being used only for the main discharge. As shown in Fig. 1, one of the electrodes is formed in two parts m, a, between which a condenser c and an inductance Tp are connected. A high resistance R is inserted between the condenser and the supply S. A winding Ts, coupled with the inductance Tp, supplies a striking voltage between the main electrodes m, h, and a choke coil I protects the supply from the striking voltage. The oscillatory glow or arc discharge across the parts m, a may be arranged to cease when the main discharge has started, or it may be maintained independently of the main discharge. Several modifications are described. Each electrode may be provided with an auxiliary electrode and starting condenser. A small auxiliary electrode may be connected to earth through a condenser. The running voltage for the lamp may be produced by the oscillatory starting circuit by coupling the two circuits through a transformer. The distance between the parts m, a may be varied automatically by mounting them on bimetallic supports. In the arrangement shown in Fig. 6, the supply to the condenser c is taken from a tapping K on the secondary of the supply transformer E.
