Abstract: 941,004. Conveyers for electrolytic baths. UDYLITE RESEARCH CORPORATION. March 17, 1960 [March 30, 1959], No. 44083/62. Divided out of 941,001. Heading B8A. A webbed carrier 54 is traversed through an electrolytic bath along a track 50 (Fig. 3) step-by-step by means of dogs 88. Dogs 88 are rigidly carried by two bars 90 which are carried by links 85 pivoted to respective pusher rods 82. The pair of pusher rods 82 are reciprocated by cylinders 84 through pivoted bell-cranks 91. The two sets of dogs 88 carried by corresponding sets of rods 82 and bars 90 are positioned on different sides of the tank and their movements are synchronized, being interconnected by racks 83, gears 84a, and connection 86. Operation of pusher.-When the cylinder 84 is actuated (referring to one set only of dogs 88), bell-crank 91 pivots so as to raise bar 90 into its upper position above rod 82. This position is defined when stop 89 on bar 90 engages the end of rod 82. Continued movement of cylinder 84 then causes forward movement (i.e. to the right in Fig. 1) of rod 82 and bar 90 as a unit. In this way the dogs 88 in their raised position engage the legs 81 of the carrier to convey it along the track 50. When cylinder 84 is retracted first bell-crank 91 pivots to lower bar 90 on to rod 82 so that dogs 88 assume their lower position. Continued retraction of cylinder 84 causes the leftward movement of rod 82 and bar 90 as a unit with the dogs in the non-engaging position. Thus, a carrier is advanced on the forward movement and on the backward movement the dogs 88 move downwards to avoid engagement with the carrier. Variation of distance of travel of carrier, Fig. 3.-The dogs 88 may be located on a bar 90 in pairs; of which the forward dog is notched and the rear dog is unnotched. The lateral position of a leg 81 therefore determines whether the forward or the rear dog 88 is engaged and therefore determines the distances of travel of the carrier.

Abstract: 968, 542. Data transfer between registers. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 30, 1960 [Dec. 30,19 59], No.44708/60., Heading G4C. Transfer between the corresponding stages of magnetic core shift registers is done by reading from one register into a capacitor and then from the capacitor into another register. The information shifted within a register is also stored in interstage capacitors. Information is read into magnetic core 1 by simultaneously applying a positive pulse to line 36 and a negative pulse to line 37, setting core 1. Negative potentials applied to lines 37 and 45 cause transistor 29 to conduct and charge capacitor 34. Core 2 is then set from capacitor 34 by applying negative potential to line 38 discharging the capacitor through winding 20. The bit stored in capacitor 34 may be regenerated in core 1 by applying negative potential to line 42 when the capacitor discharges through winding 15. To transfer the set state of core to a corresponding stage (core 5) of another register negative potentials are applied to lines 37 and 44 sending transistor 28 conductive and charging capacitor 107. The line 102 then has a negative potential applied and the capacitor discharges through winding 81 to set core 5. This may he combined with regeneration of the state of core 1 by charging capacitor 34 as already described and by charging capacitor 106 (by applying negative potential to . line 43) providing for simultaneous transfer of the contents of core 1 to a second location.

Patent GB-452472-A (GB)
Abstract: 452,472. Postal-franking and like machines. AKTIESELSKAPET HEKLA, 3, Karl Johansgate, Oslo, Norway. Jan. 10, 1936, No. 917. Convention date, Jan. 10, 1935. [Class 100 (ii)] [See also Group XIX] In postal-franking machines, cash registers, and ticket - printing and calculating machines, the counting- mechanism is adapted to be actuated by means of a number of drums or segments 10 having teeth 11 arranged in stepped formation, the drums or segments being correctly set opposite the cooperating wheels 12 of the counting-mechanism by mechanism which acts simultaneously to set corresponding type - wheels in the rotatable printing - head 5. The printing- head is secured to a shaft 4 and carries the type-wheels 6 on a pin 7, the wheels being adapted to be set in correct position by racks 9 secured to the drums 10 which are slidably but non-rotatably mounted on the shaft 4. The drums are movable along the shaft by levers 15 actuated by a bar 18 which is reciprocated by a lever 20 under the control of a cam 23 on the shaft 4. The bar 18 carries pins 25 and hooks 26 for moving the levers in clockwise and counter-clockwise direction respectively. The hooks are spring-pressed into position to engage the levers, and are adapted to be disengaged by pins 28 arranged in groups corresponding to the levers and raised into operative position by keys 35. The pins are retained in raised or lowered position by means of spring- pressed bars engaging notches in the pins. The first of each group of pins is normally held in raised position to render the hooks inoperative in case of accidental operation, and setting of any other pin in a group causes the first pin to be withdrawn. In use, the desired keys are operated, a one-revolution clutch 36, 38 is engaged, and the shaft 4 is rotated causing the bar 18 to be moved to the right. The hooks 26 move the levers 15 until released by the set pins 28, to slide the drums 10 into position for the corresponding number of teeth to engage the wheels 12 and to set the typewheels 6 in the head 5. After printing has been effected, the bar 18 returns to normal position, the pins 25 resetting the levers 15. An eccentric on the shaft 4 raises the first pin of each group to render the hooks 26 inoperative and thus returns the pins previously raised. In order that a number of impressions may be obtained from a single setting of the machine, the shaft 21 carrying the lever 20 is longitudinally slidable against the action of a spring. The shaft carries a pin normally entering a notch 46 in a member 45, but movable to engage a shallower notch 47. On pulling the shaft outwardly, the lever 20 enters a forked member 43 non-rotatably secured to the shaft and is disengaged from the cam 23. The shaft is then rotated to engage the pin with the notch 47, thus moving the bar 18, levers 15, drums 10, and racks 9 to the extent normally effected by the cam 23, and causing the drums and type-wheels to be set in positions corresponding to the operated keys 35. The shaft 4 can then be rotated without causing any movement of the bar.

An electricity supply system for a number of loads comprising essential and non-essential loads is arranged so that the non-essential loads can be switched in or out to ensure that a predetermined maximum loading on the supply is not exceeded and that the loading on the supply is maintained near the maximum demand. The loading on the supply F is sensed by current transformers CT, the output voltage of which is rectified by rectifiers R and fed to serially connected control windings N 1  of a pair of saturable reactors S R , S F . Windings N 2  are provided on the reactors to provide adjustable biasing thereof, these windings being supplied from an A.C. source PS1 by way of a rectifier bridge BR, the supply voltage being stabilized by a saturable toroid K. A reversible motor M driving cams 20 which operate switches S1-S4, has its field windings F, R connected to an A.C. supply PS2 by way of the power windings P F , P R  respectively of the saturable reactors S F , S R . Thus when the control current I 1  flowing in the windings N 1  is low reactor S F  saturates whilst reactor S R  remains unsaturated under which condition the motor field S R  will be energized and the motor will run to sequentially close switches S 1 -S 4  to switch in loads L 1 -L 4 . When the control current I 1  has a high value the motor runs in the reverse direction to sequentially open the switches S 4 -S 1 . The setting of the tap-switch P on the winding N 2  of reactor S R  sets the maximum demand to be imposed on the system whilst the corresponding tap Q on reactor S F  sets the minimum demand. When the control current I 1  is indicating a load on the system between the maximum and minimum demands both reactors will be saturated and the motor M stationary. Limit switches X, Y are provided for the motor. Lost motion is provided between the motor and the cam shaft to make the mechanism insensible to transitory changes in load.
