Patent GB-897596-A (GB)
Title: Bowling pin elevating mechanism
IPC: A63D5/08
Filed: 1960-04-20
Abstract: 897,596. Skittle alleys. AMERICAN MACHINE & FOUNDRY CO. April 20, 1960 [May 4, 1959], No. 13868/60. Class 132(2) Relates to a pin elevator in the form of an annular channel M having pin pockets 11 and rotating in the pit of the alley to lift pins 50 from a station S1 to a discharge station S2, at which the pins can be released from the channel into a device T supplying them to the pinsetter apparatus. According to the invention, the channel carries at each pocket 11 a pin gripper operated to open and closed positions by stationary cams and retained in these positions by toggle devices. At each pocket, there is secured to the channel a bracket 54 to which is pivoted at 58 a lever 56 an extension 57 of which can project through an aperture 60 in the channel so that a friction pad 64 can engage a pin 50 to hold it in place. One end of lever 56 carries a cam-roller 59 and a telescopic connection 71, 73 is pivoted at 70, 69 to the lever 56 and bracket 54 respectively. The part of lever 56 between pivots 58, 70 and the telescopic connection form a toggle and a compression spring 76 around the latter biases the toggle to its extreme positions. The annular channel is rotated in the direction of arrow B, Fig. 1, on rollers 16, 18 by a motor driven belt 46 loaded by a tensioning device 17. As each pocket approaches station S1, cam-roller 59 engages a stationary cam 98 so that the extension 57 and pad 64 are withdrawn from the pocket 11  (position C of Fig. 5). This allows entry of pins at station S1. As the pocket rises, the cam-roller 59 is engaged by a staionary cam 78 (Figs. 1 and 5) to move the extension 57 into the pocket to engage a pin (position shown in full lines in Fig. 5) or to enter the pocket if no pin be present (position D of Fig. 5). As the pocket approaches station S2, the cam-roller 59 comes adjacent a pivoted cam 74 normally located clear of the roller 59 in position E of Fig. 7. If pins are required by the pinsetter, however, a solenoid 178 is energized to lift cam 74 to the position shown in full lines in Fig. 7. Then the roller 59 engages cam 74 to open the pin holder to allow the pin to fall into device T. This also moves the cam along shaft 84 against spring pressure so that a projection 79 operates a counter 80 one step. When ten pins have been released, the counter automatically allows cam 74 to drop clear of rollers 59 so that no more pins are released until solenoid 178 is again energized. If a pocket when approaching station S2 has no pin in it, the lever 56 will be in position G, Fig. 7, and will not be moved out and will not operate the counter. This lever will be moved out before reaching station Sl by cam 98. U.S.A. Specifications 2,767,983 and 2,767,894 are referred to.

Abstract: 200,645. Smith, R. T., and Bookless, R. C. May 17, 1922. Thermionic amplifiers and generators.-A variometer for simultaneously adjusting the inductance of the oscillatory circuit and the degree of coupling to a secondary circuit comprises a movable coil and a stationary coil in series in the anode or grid circuit, and a stationary coil in the coupled circuit. The arrangement is particularly advantageous when working with short wave-lengths. As shown in Fig. 1, for transmission, the series inductances 8, 9 can be mutually displaced so as to alter the tuning of the oscillatory circuit or aerial 8, 9, 10, the same movement serving also to vary the coupling between this circuit and the reaction coil 11. The construction of the variometer is shown in front view, Fig. 3, and in section, Fig. 6. The coils 9 and 11 are wound around two cylindrical formers 13, 12, one supported within the other by screws 14 and both being stationary. The coil 8 is wound on a spherical former 15 which is rotated relatively to the other two coils by means of a handle 17 on a two-part spindle 16. The coils 8 and 9 are connected in series through a bracket 20, the free end of the coil 9 being taken to a terminal 21. Connections are made to the coil 8 by strips 18 and 19 which wind and unwind on the spindle 16. Separate terminals are provided for the coil 11. Instead of having only one movable coil, two of the coils may be rotated independently.

Abstract: 969,841. Electromagnetic switches; contact members for switches. TELEMECANIQUE ELECTRIQUE. April 8, 1963 [April 14, 1962; March 11, 1963], No. 13946/63. Heading H2B. In a contactor device of the type comprising a longitudinally movable slider 2 carrying a movable contact assembly movable into or out of engagement with fixed contacts 4 carried by a surrounding frame, the slider being moved electromagnetically in one direction against a restoring spring, the movable contact assembly comprises a contact arm 9, a follow-up arm 10 and an interposed compression spring 11, and the arms are pivoted such that the spring 11 undergoes about the same compression in both positions of the slider 2. Spaced hooks 9c on arm 9 engage around pins 10b of follow-up arm 10, which pins are used for seating the assembly in a groove 14 of the slider 2. Movement of slider 2 in direction F 1  causes engagement of bridging part 9a of arm 9 and fixed contacts 4, and pivotal movement of arm 10 away from contacts 4 to relax the spring 11. With the assembly reversibly mounted in a narrower groove 13 of slider 2, however, and with contacts 4 re-positioned also, further pins 10d on arm 10 block any follow-up movement of arm 10 when slider 2 is moved in direction F 2 , to close contacts 9a, 4 as groove 13 is only as wide as the pins 10d engaging there in. Contacts 9a, 4 are self-cleaning, and the contact arm 9 is formed from a metal stamping. Further embodiments of contact assemblies are described where the two arms pivot about pro - jections on the slider walls, Fig. 12b (Figs. 9- 13, not shown), and where the two arms mutually interpenetrate with their lower ends surrounding a common pivot pin, Fig. 15b (Figs. 14-16, not shown).

Title: Improvements in and relating to feathering propellers
IPC: B64C11/30
Filed: 1942-10-06
Abstract: 560,833. Variable - pitch propellers. BOAST, J. E. Oct. 6, 1942, No. 14031. [Class 114] In a hydraulically adjusted cbnstant speed propeller, the operating solenoid of a switch 8 controlling the circuit of an electrically driven auxiliary feathering pump 2 is controlled by a push-button switch on the lever 15 which adjusts the constant speed, e.g. through a rack 41 and pinion varying the loading on the governor 39. To feather the propeller, the lever is pushed beyond its normal limits till a contact 10 engages a contact 11, closing the solenoid circuit 9 from the negative battery pole, on pressure of the button switch, through leads 53, 55, 56 to the positive pole. The switch 8 closes a circuit leading from the negative pole to the auxiliary pump motor 1 and also closes a circuit through a solenoid switch 29 by which the circuit to the positive side of the battery is closed. The pump then actuates the servo-piston 33 to bring the blades into feathering position whereupon the rise in pressure opens a limit switch 20 and stops the motor. A holding circuit through lead 62 allows feathering to proceed when the button is released. To unfeather, the control lever is brought into the constantspeed range and the button is pressed and held down. In the lower position of the switch 8, a lead to the starter motor 6 is closed. Specification 560,836 is referred to.

Title: Improvements in conveyor systems
Inventor: GREBE KONRAD
IPC: E21F13/02
Filed: 1954-05-18
Abstract: 776,928. Conveyer systems. GREBE, K. May 18, 1954, No. 14619/54. Class 104 (2). In a conveyer system having branch tracks and in which belt lengths are moved along a support structure by drive units arranged on sections along the conveyer system and set into operation by an approaching belt length, the arrangement is such that in the non-aligned branch tracks the drive unit nearest the track switch is automatically stopped, after it has been started by an approaching belt section, before the belt section can run into the track switch. A track switch tongue 2 is moved by a compressed air cylinder 3 controlled from a central control station 1. In the arrangement shown the tongue 2 is locked in the aligned position with the left-hand branch track by a piston-rod 6 of a locking cylinder engaging a notch 5 in an arcuate guide 4 carried by the tongue 2. The additional forward movement of the piston-rod 6 due to its engagement with the notch 5 enables compressed air to pass through a pipe 7 to actuate a control valve 8 so as to cut off the compressed air supply line 9. If the air supply line 9 is opened a detector 13 is effective to control the air supply to a control valve 11 to close an air supply line 10 and so stop a motor 12 if it has been put in operation by a detector D to allow air from the line 10 to reach the motor 12. The detectors D and 13 are operated by the leading edge of the belt section. In the central branch track the piston-rod 6 (in the position of the switch 2 shown) does not enter the notch 5 and so compressed air cannot enter the associated pipe 7 and a valve 14 is not operated so that compressed air can now flow from a pipe 15 to a detector 17 which becomes effective. The air for the motor 19 of the driving unit flows through the valve 18 and the motor operation is controlled by detectors D which permit a belt section to move forward until its leading edge operates the detector 17. Operation of the detector 17 allows air to flow from the pipe 16 to a valve 18 which cuts off the air supply to the motor 19, thus stopping the belt section conveyer short of the track switch 2. Starting and stopping of the driving units may operate signals at the central control station 1. The system may have upper and lower runs and the track switches in each run may be operated independently of each other.
