IPC: B65H7/06
Filed: 1967-07-13
Abstract: 1,165,808. Feeding sheets. ADDRESSOGRAPH MULTIGRAPH CORP. 13 July, 1967 [29 July, 1966], No. 32400/67. Heading B8R. Sheets are fed simultaneously from at least two stacks S1, S2 to a printing mechanism by an apparatus comprising suction separators 43, 46, means detecting the failure of the feeding of any sheet, and sheet diverting means 110 controlled by the detecting means for diverting the remaining sheet, or sheets, to avoid the feeding thereof to the printing mechanism. Separators.-Suction separators 43, 43 are mounted on bar 48 which rocks about shaft 54. Lever 120 disconnects the suction supplied to the separators by pump 36, when this lever strikes plate 122, thus causing the sheet to be released to feed rollers 30, 32 (34, Fig. 3). Sheet forwarders.-Sheets pass from feed rollers 30, 32 to conveyer tapes 70. Faulty feed controls.-The failure of the separators to grip any sheet causes a pressure increase in line 38. This is detected by a device 72, containing a flexible diaphragm which then operates a control switch 100 to cause deflector gate 110 to be operated thus diverting any sheet fed during the cycle to bin 112. Any operation of the deflector gate when the pressure in line 38 drops due to the release of correctly fed sheets to rollers 30, 32, is prevented by switch 107 which disables the deflector mechanism except during an actual separation.

Title: An improved direction indicator for vehicles
IPC: B60R16/00
Filed: 1923-12-29
Abstract: 211,106. Junghans, H., and Glogauer, F. Feb. 10, 1923, [Convention date]. Momentary contact switches, mechanical; clockwork actuation.-A direction indicator for vehicles comprises a knob 55 which is first rotated till the pointer 56 indicates " right, " " stop " or " left " and then momentarily depressed in an axial direction, this latter operation serving to complete an electric circuit to the selected indicating lamp and at the same time to wind up and release a train of clockwork which in running down automatically interrupts the indicating circuit after a given interval of time. The knob 55 is fixed to the spindle 58 which carries a member 88 which has pivoted to it a member 89 carrying a snap catch contact 90, and a spring normally holds the member 89 so that an arm 91 of it engages a stop 93 fixed to the spindle 58. Rotation of the knob 55 and spindle 58 brings the contact 90 opposite one of the gaps between or at the end of three U-shaped contacts 81, 82, 83 mounted on a sector-shaped member 80, which is loosely mounted on the shaft 58 and connected by links with a member 65. Depression of the knob 55 moves the member 65 to the right, Fig. 1, and thereby rotates the sector 80 so that the contact 82, for example, Fig. 3, moves across the contact 90 and eventually reaches a position in which its left end is opposite the contact 90. The stop 93 on the shaft 58 simultaneously moves the arm 91 so that the contact 90 engages the contact 82 and snaps over into the position shown in Fig. 1. Movement of the member 65 to the right has also wound up a spring 68. When the knob 65 is released, the spring 68 slowly unwinds, moving the member 65 and the sector 80 back to their original position. During this process the contact 90 slides over the contact 82 till the gap between contacts 82 and 83 is reached, when contact is broken.

Abstract: 819,033. Control of D.C. motors; controllers. GENERAL ELECTRIC CO. Nov. 16, 1955 [Nov. 16, 1954], No. 32847/55. Class 38 (3). A resistor for controlling an electric motor has a plurality of sections A-H connected in series with voltage taps 11-18 therebetween, a pair of bus wires 23, 24, being connected respectively to one end of the resistor and to a voltage tap 11 adjacent said end and being adapted to be connected to the remainder of the voltage taps in a predetermined manner. Contactors 1, 2 are provided for connecting each of the bus wires to a load circuit and a switch 31 connects the other end of the resistor to the circuit, whereby the making and breaking of the connections between the bus wires and the voltage taps varies the effective resistance. The section A is short-circuited by moving controller 25 from the first to the second notch, and, on the third notch, sections A and B are connected in parallel with each other and in series with the sections C-H. In moving to the fourth notch, the sections A and B are short-circuited. Sections A, B and C are connected in parallel on the fifth notch, and are serially-connected with sections D-H. Proceeding to the sixth notch shunts sections A, B and C. On the seventh notch, sections A and D are connected in parallel, and this combination is placed in series with sections E-H. Movement to notch 8 puts sections A, B, C, D in parallel with one another and in series with sections E-H. Proceeding to the ninth notch causes the sections A, B, C, D to be short-circuited. This sequence of operations is continued until the whole of the resistance is removed in the thirty-first position of the controller 25, Figs. 2, 3 (not shown), the arrangement being such that none of the contactors 1-9 are opened whilst carrying current. In a modification, some of the notches are omitted to shorten the sequence and to make the changes of the resistance more closely approach a geometrical progression. As shown, the resistance is used for controlling series motors 19, 20, the selector switch 31 allowing the resistance to be connected for accelerating the motors, for dynamic braking, or for field regulation. Specification 692,099 is referred to.

Abstract: 628,753. Cathode-ray oscillographs. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd.,  and BAKER, G. T. Nov. 6, 1946, No. 32917. [Class 37] [Also in Groups XXXVIII and XXXIX]  In a display arrangement employing a cathode-ray tube associated with means for applying variable and steady voltages to the deflecting plates of the tube to cause a number of characters to be displayed as disclosed in Specification 624,089, switching means are provided for blacking-out the screen during intercharacter traverse and during fly-back. The invention is applied for displaying a calling subscriber's number in automatic telephone systems similarly to Specification 624,089. On the momentary operation of a key KIA starting relay HA operates and locks and relay PU interacts with magnet DSM of a distributer switch. The latter, over wipers DS1, DS3 connects up character-forming potentials (generated as described in Specification 624,089) for the digits of a four-digit number in succession to X and Y plates PX1, PY1 of a cathode-ray tube CRTA and over wiper DS2 connects steady potentials to the other,X plate PX2 to space the respective digits on the screen. Relay PU at each operation energizes SCA to remove a paralyzing bias which is normally applied to the tube grid and suppresses the beam while the distributor is moving. As shown display tubes at two operating positions are connected in parallel but the starting relays HA, HB of the positions are arranged so that any one can remain locked up and consequently the tube associated with the other remains dark. In a modification, Fig. 3 (not shown), for use when a more extended display than four digits is required, the distributor operates by self-interruption and the stepping circuit includes the primary winding of a transformer, the secondary of which is in circuit with the grid of the tube so that the opening of the interrupter contacts induces a voltage surge in the secondary winding to suppress the beam. Specification 627,577, [Group XXXIX], also is referred to.
