Patent GB-684482-A (GB)
Title: A new or improved machine for delivering predetermined quantities of screws or otherheaded rod-like articles
Inventor: BALLARD ALFRED GEORGE
IPC: B65B1/14
Filed: 1949-07-22
Abstract: 684,482. Counting apparatus. G.K.N. GROUP SERVICES Ltd. July 21, 1950 [July 22, 1949], No. 19289/49. Class 106 (i). [Also in Groups XVII and XXX] Mechanism for feeding predetermined numbers of screws &c. for packing into containers comprises a rotary feeder 11 having radial slots 23 into which the screw shanks are pushed by a member 16, means at the end of each slot to separate the outermost screw for movement along the slot to a gate 52 and means for opening all the gates simultaneously to deliver one screw from each slot. Screws from a vibratory feeder fall down shoot 13 into a rotating hopper 12 and are stirred by flexible members 16, rotated at a different speed, until the screw shanks fall into the slots 32. Centrifugal force feeds the screws along the slots between sectors 26 until the first screw in each slot displaces a lever 43 and passes on to gate 52, while said lever forces a rod 42 against spring action into the slot to stop the next screw. The said first screws make electrical contact with outer sectors 27, insulated from sectors 26 and connected in circuit with the coil 34 of an electromagnet. When all sectors 27 are connected by screws, coil 34 is energized and attracted to an armature in the feeder 11, thereby rotating a spider 35, on which the coil is mounted, relatively to the feeder. Arms 41 of the spider open the gates 52, normally held closed by centrifugal weights 54, to deliver one screw from each slot into hopper 57 and thence into container 60. Current is fed to coil 34 through slip-rings 32. in a modification, the gates may be opened by completion of a circuit by the screws through the gates instead of sectors 27.

Title: Improved circuit arrangement for controlling electric motors
Inventor: PROWSE DONALD WINDSOR
IPC: B66C13/24
Filed: 1960-06-01
Abstract: 982,393. Automatic speed control. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 26, 1961 [June 1, 1960], No. 19477/60. Heading G3R. A system for accelerating an electric motor comprises a circuit for automatically deriving from a step-function voltage, as produced in accordance with a manual setting, one which increases at a predetermined rate, the latter voltage being used as a speed reference voltage for the motor. Such a circuit comprises amplifier A1 supplied from input terminals AT1, AT2, and amplifier A2 connected to output terminals OT1, OT2, a feedback signal being supplied through capacitor C from the output to the input of the amplifier A2. A clamping circuit which limits to a preset range the voltage change rate comprises resistor R4 in series with Zener diodes Z2, Z3, as described in Specification 938,563. The operation of the clamping circuit is modified by a signal corresponding to the armature current of the motor, or to the difference between the demand speed and the actual speed, such signal being applied across resistor R3. If the voltage across this resistor exceeds a voltage determined by Zener diode Z1, transistor VT presents an open circuit and the voltage across diodes Z2, Z3, falls to zero; so reducing the rate of change of reference voltage.

Title: Brake shoe adjusting mechanism
IPC: B66D5/00
Filed: 1944-10-10
Abstract: 581,064. Brakes. SCHNELL, S. Oct. 10, 1944, No. 19504. [Class 103 (i)] An automatic adjuster for a brake shoe, or shoes, comprises a cylindrical member 23 pivotally connected by a pin 24 to a channelsectioned lever 5 carrying the shoe, a cylindrical shell 26 secured to the member 23 and accommodating a piston-like member 27 secured to a rod 28 which slides in a transverse bore in a pin 35, and an element 40 pressed by a spring 42 to hold the rod 28 frictionally in position. The piston 27 has a clearance 30 from a stop 29 welded to the shell 26 and a spring 31 tends to keep the piston against the member 23. The clearance 30 determines the shoe-clearance. The pin 35 and a sleeve 33 having a transverse bore to receive the rod 28, are free to pivot in holes 36, 37 in fixed angles 3, 4. The invention is described as applied to a brake having two shoes applied externally to a drum, the shoe-carrying levers 5 being interconnected for symmetrical shoe application. When wear of the lining occurs, the upward movement of the pin 24, on application of the brake, becomes greater than the clearance 30 and the stop 29 entrains the piston 27 and rod 28, the latter being moved against the frictional resistance of the element 40 which locks the rod 28 in its new position of adjustment.

The air may then pass through filtering screens 26 and silencing material consisting of aluminium chips 27 to the inlet 12 of the carburettor 11. The filter and silencer may be omitted. In a modification, Fig. 4, the pump 19<a> draws the oil from the crankcase through the casing C and a bye-pass 28 may be provided to allow the oil to flow direct to the pump in cold weather. The bye-pass is controlled by two-way valves 29 actuated from the dashboard of a vehicle. The Specification as open to inspection under Sect. 91 (3) (a) states that the cooling medium may be the fuel constituent of the mixture. This statement does not appear in the Specification as accepted.
