Title: Control system for machine elements
IPC: B24B47/06
Filed: 1961-04-27
Abstract: 943,754. Grinding. MSO MASCHINENUND SCHLEIFMITTELWERKE A.G. April 27, 1961 [May 7, 1960], No. 15213/61. Heading B3D. A grinding wheel 2 on a slide 1 is advanced by a piston 5 through a predetermined distance, and after a first run the pressure of the fluid supplied to cylinder 4 is adjusted automatically so that subsequent movements of slide 1 over the predetermined distance take place in a predetermined desired time interval. The desired duration for the movement of slide 1 is preset into a timing device 33, and the desired duration of the final period of the movement, in which slide 1 is advanced at a reduced speed, is preset into timing device 34. On pressing start button 32 solenoid-operated valve 11 supplies fluid to duct 35 at a pressure determined by the throttle opening of valve 21, and as soon as slide 1 begins to advance, timing device 33 is started. When cam 7 operates switch 8, valve 15 is operated to connect duct 37 to valve 18, the throttle opening of which determines the speed of advancement during the final part of the movement, and timing device 34 is started. Switch 9 is actuated when slide 1 reaches its final position and energizes the contacts of devices 33, 34 and at the same time operates valve 11 to supply fluid to duct 36 to reverse the movement of slide 1. Devices 33, 34 then supply pulses to respective step-by-step motors 25, 27 which are driven by an amount depending on the difference between the desired time and the actual time taken for the respective movements, and in a direction depending on the sign of this difference. Motors 25, 27 drive potentiometers 24, 26 which form part of servo-systems driving motors 22, 19 which in turn regulate valves 21, 18 so that a subsequent advancement of slide 1 over the predetermined distance will have the desired duration, and the final movement at a reduced speed will also have a predetermined duration.

Title: Improvements in coin-operated vending machines
Inventor: SCHREIBER WILHELM
IPC: G07F5/18
Filed: 1959-05-06
Abstract: 851,438. Coin-freed vending apparatus. LUCKENWALDER METALLWARENFABRIC VEB. May 6, 1959, No. 15572/59. Addition to 821,786. Class 27 The compartment-type vending machine of the parent Specification in which each compartment flap is locked by the spring-loaded armature 26 of a solenoid 5, has a disc 25 on the armature for operating contacts 1, 2, 3 and 4. Inserted coins 33 stack on the armature of an energized solenoid 13 and the last coin momentarily closes a contact 10 so that a relay 9 is energized and closes a holding contact 8 and a contact 7 for preparing the circuit for all the solenoids 5. When the push button of a selected compartment is pressed, the appropriate solenoid 5 is energized through switch 6 to withdraw a spring-loaded bolt 24 from a hole in the flap segment 22-and the flap springs open. Solenoid 5 holds, even after the push button is released, over contact 4, which is closed by the disc 25 on the armature, and contact 2 is also closed to shunt the solenoid 13 and release the stacked coins. Contacts 1 and 3 are opened by the disc and consequently the circuit for all the other solenoids 5 is interrupted. The shunt circuit through contact 2 allows a low-resistance solenoid 14 to withdraw a coin diverter from the coin channel and the coins fall to a coin box 30, operating a contact 16 and breaking the circuits for relay 9 and the solenoid 5 so that the parts return to their initial positions. The resilient arrangement of the bolt 24 allows the armature 26 to return under spring action and allow the contacts 1 and 3 to close, restoring the initial readiness of the machine, even if the flap is not closed. If a coin-return button is pressed, a coin tester 31 opens and releases any held-up coins to a return cup 28. The tester also reverses a switch 11, 12 so that the circuit to the relay 9 is shunted through a resistance 15, thus preventing opening of a compartment and the solenoid 13 is de-energized, releasing any stacked coins for deflection to the return cup by the diverter 14. When the contact 3 is opened by the energized solenoid 5, the circuit through contact 11 is broken, so that operation of the coin return button will not then return coins. For filling the compartments, the operator turns a safety lock for the column of compartments and thus operates a switch 17 providing circuits for opening any compartment on depression of the appropriate push button.

Title: Improvements in or relating to devices for tightening screw closures in or around the mouths of bottles or like containers
IPC: B67B3/20
Filed: 1955-06-03
Abstract: 786,099. Applying screw closures to containers. CROWN CORK CO., Ltd., and BECK, N. June 4, 1956 [June 3, 1955], No. 16038/55. Class 125(2). A device for tightening screw closures in or around the mouths of bottles or like containers, comprises in combination a spring-loaded plunger 19, telescopically mounted in a spindle 24 and carrying closure engaging means, which is enabled by means of the spring-loading and telescopic mounting to engage closures on containers of different heights, rotary driving means, in the form of a pulley 27, connected to the spindle 24, co-operating clutch members 40 and 33 connected to the plunger and spindle respectively and conveying the drive to the plunger, together with spring means 16 urging the clutch member together, the combination being characterized in that the spring means are adjustable from the exterior of the device to exert such a pressure on the clutch members as to permit clutch slip after a selected degree of closure tightening imparted by the rotation of the plunger. The device is mounted in a cylindrical casing 12 with end members 11 and 13. The end member 13 forms a bearing for the spindle 24 which is flanged at its lower end 33 to form a clutch member while the pulley 27 and a ball race 34 are so arranged that there is no vertical movement of the spindle. The lower end member 11 has a screw-threaded bore which receives a bush 14, the upper end of which is cupped to receive the clutch spring 16. The plunger 19 telescopically engages the spindle 24 at 32, a spring 31 seated in the spindle urging the plunger downwards. On the upper end of spring 16 is seated a member 35 carrying a ball race the rotating side of which is fixed to a friction pad 40 engaging the upper clutch member 32. The lower clutch member is associated with the plunger by means of a bolt 39 which slides in a vertical slot 38 in the plunger, which is thus adjustable for stoppering containers of differing heights. The spring 16 is adjusted to permit clutch slip of varying degree by turning the bush 14 in which the spring is received. The device may replace the crowning head in a crown corking machine. One arrangement of a number of devices is indicated in Fig. 3 in which a fired belt 28 is arranged on the pulleys 28 so that anti-clockwise movement of the devices causes tightening of the stoppers.
