Title: Improvements in and relating to animated advertisement signs or displays and to controlling motor mechanism for the same
IPC: G09G3/00
Filed: 1947-04-16
Abstract: 622,894. Changing signs. ROSE, F. G. April 16. 1947, No. 10124. [Class 3(i)] An advertising or display device comprises a translucent panel 2 sub-divided into spaces by rear partitions 4, each space being lit by one or more lamps 10 which are sequentially controlled by a selector switch 15 ; the selector switch is impulseoperated by a multihump cam 34 through a switch 37, the cam is driven by a synchronous motor 32, and the sequence is controlled by an initiating switch 12 and switch means which keep the motor 32 energized to the end of the cycle. The panel 2 is mounted in a frame 1 of metal or plastic material and the display material is printed on a sheet 3 of translucent paper attached to the rear of the panel 2. The partitions 4 are of cardboard or like material attached to the sheet 3 and have a backing sheet 5 of cardboard, rubber or felt. The lamps 10 are mounted on a board 8 which is attached to a frame 7 which also carries the control mechanism. The frame 1 together with the panel 2, the partitions 4 and the backing sheet 5 may be removed as a whole from the frame 7 to expose the lamps 10, the backing sheet 5 having holes 6 through which the lamps can pass. To start the sequence, the switch 12 is momentarily depressed. Its contact 14 starts the motor 32 and its contact 13 energizes a stepping electromagnet 23 of the selector switch 15 through contact 16x of bank 16 of the switch 15. The electromagnet moves a spring-loaded pawl 25 and, when the switch 12 is released to de-energize the electromagnet, the switch 15 is stepped one contact by the pawl 25 moving ratchet wheel 23. This movement of the switch breaks the circuit for the electromagnet through the switch 12 and so leaves the electromagnet under the sole control of switch 37 which is controlled by the motordriven cam 34. The circuit for the cam motor 32 is broken at switch 12, but an alternative maintaining circuit is completed by the switch 15 through the contacts of its bank 17, all the contacts except the first being interconnected. Thus the switch is stepped periodically by the cam 34 and lights the lamps in the desired sequence. The sequence is terminated when the switch 15 reaches its initial position, its contacts 17x, 18x breaking the motor and lamp circuits. Additional contact banks for the lamps may be provided on the selector switch and, if desired, more than one sequence may be provided on the one selector switch by dividing the motor circuit maintaining connections on bank 17 into groups separated by an unconnected contact. The motor will then stop after each group. Suitable modifications are made to the connections of banks 16 and 18. The motor 32 may be maintained in operation by a second cam-controlled switch on the motor shaft instead of by a selector switch bank. The starting switch may be operated by clockwork.

Abstract: 971,085. Gas chromatography systems. BECKMAN INSTRUMENTS Inc. March 30, 1962 [April 3, 1961], No. 10538/62. Heading B1L. [Also in Divisions G1 and G3] The sample and reference columns of a gas chromatograph are variably heated by blowing hot air over them. The air is heated by an automatically controlled electric heater and the datum setting of this control is continuously adjusted by a photo-electric follower in accordance with a line on a moving chart. The use of a linear temperature programme shortens the time for analysis and increases the sharpness of the component peaks. A non-linear programme would permit additional control of the spacing between peaks. As shown in Fig. 2, the column 21 is supported in a thermally insulated housing 19 and surrounds a heater unit in which air is drawn through a top plate over a heating element by means of a blower wheel and passes out through slots 45. The reference column 22 is located above the separating column. Sample is injected at 27 and the two streams of gas are compared by conductivity detector 28.

Title: Magnetic memory circuits
IPC: G11C11/04
Filed: 1961-03-23
Abstract: 901,869. Magnetic data storage apparatus. WESTERN ELECTRIC CO. Inc. March 23, 1961 [April 1, 1960], No. 10614/61. Class 40 (9). In a magnetic matrix store in which the rows are defined by conductor loops 15 and the columns are defined by bi-filar loops 10 wrapped with a helix of magnetic material, demagnetization effects of the storage areas of magnetic material in the region of the row loops 15 is avoided, and a more compact structure made possible in consequence, by registering a bit with the magnetization in one limb of a column loop 10 in one direction and the magnetization in the other limb in the opposite direction. A row is read-out by a pulse on the row loop and induces current in each limb of the column loop according to the magnetization encountered in the helix. The " 0 " state may be the read-out state, or a state with the helix on one limb magnetized oppositely to that on the other but both limbs being magnetized oppositely compared with the " 1 " state. Read-out will then produce either no output or an output of one polarity for the " 0 " state, and will produce an output of opposite polarity for the " 1 " state. Since the limbs of the column loop conductors are oppositely directed, read-out of a " O " state where no turn-over occurs in the helix results in oppositely-poled " sneak " pulses which cancel in the output circuit. Writing in of information is done with a half-write pulse on a row loop and an appropriately valued pulse around each column loop. Selection of appropriate column pulses is shown done by wiper switches but this may be done electronically. Writing in may be effected by means of the column loop pulse alone if the length of the magnetic helix forming a storage element adjacent each row loop is so small as to make remanence almost unstable. In this event writing-in follows reading-out and dislodges the remanent point of the helix in one limb or the other depending on the bit value. Once dislodged the couplet formed by the portions of helix from each limb become more stable and are not disturbed by writing pulses used on the same column to register bits in other rows, halfwrite row pulses are therefore unnecessary. Specification 877,731 is referred to.

Title: Axial type piston pump or motor
Inventor: HERTER MARTIN
IPC: F01B3/00
Filed: 1968-03-05
Abstract: 1,212,281. Reciprocating pumps and motors. M. HERTER. March 5, 1968 [March 14, 1967], No. 10649/ 68. Heading F1A. [Also in Division F2] A reciprocating pump or motor having an adjustable wobble plate 4, Fig. 1, has a rotary cylinder block 8 connected to the shaft 2 via a coupling member 3. The latter is splined at 32 to the shaft and has at least one radially-extending rib 34 in engagement with a groove 36 in the cylinder block. One or more plate springs 14 or a helical spring 14<SP>1</SP> is arranged within the cylinder block to bias a ported control disc 10 against a stationary ported valve plate 11. This biasing action of the spring is assisted by the force generated by pressurized oil in the cylinders 38 acting on the tapering walls of ports 40 in the disc 10. The groove 36 is made wider than the thickness of the co-operating rib 34 to permit a slight amount of relative rotation between the cylinder block and shaft, so that on starting of the motor the ports 40, 41 can become fully aligned before the shaft and the load connected thereto are driven. The cylinder block surrounds the shaft with clearance so that bending of the shaft due to eccentric loading thereof will not tilt the cylinder block and result in leakage between the disc 10 and plate 11. The pistons 9 each have a cupped end which is received in a respective radial channel in the wobble plate 4 and engages a ball 24. Each radial channel is formed between a pair of sectorshaped members (7), Figs. 3 and 4 (not shown), rivetted to the back wall of the wobble plate. Pressurized oil is delivered from the cylinders 38 to the cupped ends of the pistons via longitudinal bores 64 in the pistons, to lubricate and "float" the balls 24 during the pressure strokes of the pistons.
