Title: Improvements in type ejectors for type composing machines
IPC: B41B3/00
Filed: 1928-04-10
Abstract: 289,009. Poeppelmeier, F. H. April 19, 1927, [Convention date]. Setting type. - Means for ejecting type, particularly grooved short-bodied type, such as are used in duplicating machines, from a type-setting machine comprises an ejectorarm 9, Fig. 1, operated by a crankdisc 7 on a rotary shaft 2, and adapted to enter the lower end of a type shoot 11, and to eject the type into a chase 13. The outer end of the arm 9 is guided by a block sliding in a guide 39, so that the ejector has a path of movement resembling a figure eight. The type descending through the shoot 11 is first intercepted by a control pawl 15 pivoted to a lever 17, which is operated by a cam on the shaft 2. The pawl 15 is connected to the lever 17 by a spring 19, and a fixed pin 30 acts to withdraw the pawl upon the descent of the lever. The type is raised by the pawl 15 to allow sufficient clearance between it and the type below to permit the entrance into the shoot of the nose of a timing- pawl 26, which is pivoted to the end of the lever 17, and is pressed inwards by a spring. Upon the descent of the lever 17, the pawl 26 forces the type below it into the path of the ejectorarm 9. Just before the ejection of the type, the nose 44 of a pinch-slide 42 presses the type next above against the wall of the shoot 11, so as to hold it stationary during the rise, of the timing- pawl 26. The mechanism is contained in a housing 1, provided with a hinged cover having means for locking it in closed position.

Title: Automatic frequency control in radio circuits
IPC: H03J7/16
Filed: 1942-07-30
Abstract: 557,147. Panoramic receivers. COLE, Ltd., E. K., and MARTIN, A. W. July 30, 1942, No. 10647. [Class 40 (v)] In a panoramic receiver of the superheterodyne type, the I.F. output is fed to circuits 4, 5 tuned to frequencies on either side of the intermediate frequency, which circuits feed diodes 2, 3 the outputs from which are applied to the grids of amplifiers 6, 61. The outputs from valves 6, 61 are taken from points 8, 81 and fed to grids of a double triode 10 in the anode circuits of which are relay coils 16, 17 for operating contacts, Fig. 2 (not shown) controlling a motor (not shown) which tunes the local oscillator continuously through the desired frequency band. In the absence of a signal, the tuning is swept through the reception band until a signal is encountered which produces a voltage in one of the circuits 4, 5 sufficient to operate one of the relays 16, 17. This causes the motor to run until the I.F. is between the tuning frequencies of the circuits 4, 5 at which point both relays are operated to stop the motor. When the signal ceases the motor resumes hunting, being automatically reversed at the ends of the tuning range.

Title: Improvements relating to centrifugal pumps
IPC: F04D15/00
Filed: 1952-04-29
Abstract: 722,203. Centrifugal PUMPS. HOPKINSONS, Ltd., BROWN, R. L., and SEWELL, G. April 20, 1953 [April 29, 1952], No. 10725/62. Class 110 (1). A centrifugal pump comprises a leak-off valve at the delivery, actuated by an electromagnet which is energized by a thermostatic switch subjected to the temperature of the water at the delivery or at the delivery and suction. Fig. 2 shows an arrangement in which water from the balance chamber c of the centrifugal pump a, or from the delivery pipe i, is circulated over a thermostat d and returned to the suction pipe e, while water from the suction pipe e is circulated by way of pipes k and m over a thermostat j. If the temperature at delivery rises unduly in relation to that at suction, the differential action of the two thermostats actuates a contactor f to cut off the current through the solenoid g of an electromagnetically operated leak-off valve h, thereby permitting the delivery pressure to open the valve. The consequent increase in the flow through the pump prevents the generation of excessive temperatures. A non-return valve n is provided in the delivery pipe i. Thermostat j may be omitted, the control of the valve h then being in accordance with delivery temperature only. Fig. 6 shows the electrical circuit. When the pump is put into operation, the switch 11 of the thermostat d is on contact 25, and current from the A.C. supply 12, 13 flows in the path indicated by heavy lines, thereby energizing the solenoid 15 of the contactor f and causing the contactor switches 16, 17 to close. Switch 16 energizes the solenoid g through metal rectifiers 14 to cause closure of the valve h, while switch 17 closes a circuit which maintainsthe current through the solenoid g in the event of the switch 11 moving off the contact 25. Switches 18 and 20, carried by the respective solenoid plungers, open to insert resistances 19 and 21 into the respective solenoid circuits to reduce the solenoid currents to the holding values. If the pump delivery temperature rises sufficiently, switch 11 closes on contact 26, thereby shorting out the solenoid 15 and causing the contactor f to return to the inoperative position. Valve h is then free to open.

Filed: 1940-06-24
Abstract: 542,228. Feeding biscuits from stacks. BEE BEE BISCUITS, Ltd., and BUXBAUM, E. K. June 24, 1940, No. 10813. [Class 117] [Also in Groups XVII and XXX] Apparatus for handling biscuits or like articles, such as transferring them to icing machines or to packing containers or wrappers, comprises a suction head 2 carried by a movable transporter. The suction head consists of a tubular member having a flared end 1 of soft rubber and connected by flexible tubing 44 to a suction pipe 45. The head is carried by a bar 3 and vertical plunger 4 which slides, under the control of a compression spring 8, in a guide 5. A cam lever 11, actuated by a link 13 and rocking lever 14 from a cam 17, acts on the plunger to impart a short vertical reciprocating movement to the suction head to pick up a biscuit and a longer reciprocating movement to deposit it in a container 24, which may be mounted on a conveyer 22. A valve 46 for making and breaking the vacuum is actuated in synchronism with the movements of the head by levers 47, 49, a connecting rod 48, a spring-pressed rod 50 and cam 18. The head may have a lateral and reciprocating movement by engagement threads on the plunger and guide, and the length of the stroke may be adjusted by an abutment 43 engaging a projection 42, while the position of the suction head may be varied to accommodate articles of different thickness by adjusting the tubular holder 2. The containers 24 are filled by mounting them in succession on a conveyer which is given a step-by-step movement past a series of feeding devices, the lengths of the stroke of the heads being adjusted successively to an amount corresponding to the thickness of a biscuit. Alternatively the holder may be lowered after each cycle of a single feeding device by a similar amount. In the arrangement described, the biscuits are fed to the packing device, by a reciprocating slide 29 working across the foot of a stack of biscuits in a magazine 27. The slide is actuated by a cam 37, acting through a rocking arm, connecting rod 38, lever 34 and adjustable link 36, which is connected to the slide by a readily disconnectible universal joint 33 to allow the substitution of slides of different dimensions.

Filed: 1953-04-21
Abstract: 733,514. Charging skips. SKIP CIE GES. April 21, 1953, No. 10940/53. Class 78 (4). A skip loading apparatus is provided with a locking circuit which prevents accidental double loading of the skip by preventing the gate 5 re-opening until contacts 14 have been opened by the skip moving to a discharge station or, in the case of a two-skip system, by either the other skip moving into the filling position or the discharge gate of the other filling hopper being opened. As shown applied to a two-skip system in which a pair of hoppers 1, 2 are alternately filled through a sliding gate 7 ; on an empty skip 3 arriving at hopper 1, change-over switch 11, 12 is moved to the right and through gate-operated contacts 17, skipoperated contacts 13, contacts 21 and a changeover switch 18, an electromagnetic valve 15 is energized and effects opening of gate 5. Simultaneously, relay 16 is energized through contacts 12, 14 and locks over contacts 16a. When the skip is filled, switch 11, 12 is moved to the left so de-energizing valve 15 which closes the gate 5. A circuit is now closed through contacts 16b to relay 20 which opens contacts 21 and locks over contacts 22. Thus the valve 15 cannot be re-energized until contacts 14 have been opened to cause relays 16, 20 to release. By means of the change-over switch 18 the self-locking manual system can be rendered inoperative, loading then being controlled automatically by time relays 19.
