Abstract: 1459902 Selective signalling C STIEFENHOFER KG 1 Feb 1974 [2 Feb 1973] 4842/74 Heading G4H [Also in Division H3] In control apparatus for use by an at least partially paralysed person, a first selector is stepped by each actuation of an input switch to route pulses generated during the actuated periods to step a plurality of second selectors (one per actuation), and a plurality of servo devices are provided each operable in response to a respective combination of one output of each of the second selectors in conjunction with a control signal provided in response to termination of a cycle of actuation periods of the input switch, the input switch being operable by the person for periods determined by him. The input switch may be operated pneumatically. The frequency of the pulse generator may be adjustable. The positions of the second selectors are indicated on lamps, and so are which servo device is selected. The second selectors can be automatically zeroized. A first embodiment has a pair of input switches which can be used as an alternative to double actuation of the input switch above (also present). The servo devices may control a light switch, typewriter, radio and TV (on/off and channel selection), start and end of an analogue operation, and making of a telephone call. In the last case, some of the outputs correspond to receiver raising/lowering, loud-speaker loud/soft selection, dialling digit values &c., and ten outputs corresponding to the ten digit values set respective stages of a shift register, dial pulses being generated with shift-out of this register until the set state of the register is shifted out of the register (Fig. 4, not shown). Some of the outputs may be encoded using NANDs into 5-bit code, then serialized and transmitted (Fig. 5, not shown). Two outputs may select respective third selectors for control by the input switch, combinations of the outputs of these selectors being used for control purposes as above.

Abstract: 879,025. Setting-up collapsed cartons. ROSE BROS. (GAINSBOROUGH) Ltd. May 14, 1959 [Feb. 15, 1958], No., 4991/58. Class 94(1). A blade 19 is inserted into a collapsed carton 11 and moved transversely with the carton over an arcuate path between curved walls 17, 18 so that the wall portion 15 of the carton extending laterally of the blade pivots about a score line adjacent to the edge of blade 19 through an obtuse angle so as to cause the carton firstly to open and then partially to collapse in the opposite direction. The blade 19 is attached to a flat surface 29 cut diametrically across the boss 31 of an arm pivotally mounted in an actuating arm 33 slidably mounted on a square shaft 34 with a camoperated arm 37. The arm 33 is embraced by a housing 39 reciprocated on a slide bar 41 by a link 42 and a cam mechanism. The arm 32 is connected by a link 43 to the housing 39 to form with the actuating arm 33 a parallel motion linkage. For insertion into successive cartons 11, the blade 19 is thus reciprocated by the housing 39. The collapsed cartons are for along a supporting platform 12 by a chain conveyer 13 and are seized in succession by grippers 16 and positioned over the mouth of the arcuate channel formed by the curved walls 17, 18. The blade 19 then enters the collapsed carton and moves arcuately down the channel, the upper portion of the wall 17 forming an abutment which causes the wall 15 of the carton to pivot through more than 90 degrees. The channel guides the carton to a pocketted conveyer 44, the wall 18 of the channel being cut away to allow passage of the pockets. The wall 17 of the channel comprises a pair of spring-urge fingers.

Title: Improvements in or relating to synchronising devices for use in electronic calculators
IPC: G11B20/16
Filed: 1957-02-15
Abstract: 802,312. Automatic-phase control systems. COMPAGNIE DES MACHINES BULL. Feb. 15, 1957 [Feb. 24, 1956], No. 5259/57. Class 38 (4). [Also in Group XIX] A pulse train is synchronized with the rotation of a magnetic drum by equidistant control marks on the drum. A magnetic drum 1, Fig. 5, comprises a control track 2 with equidistant marks 3 read by the head 4 to produce pulses 15a, Fig. 2. The frequency of the pulses generated from the sinusoidal oscillator 5 is controlled by a reactance tube 7. Square pulses 10, Fig. 2, are derived from the oscillator 5 by a clipper stage 6, and a selector 8 generates the pulse trains 11, 12 therefrom which are applied to the flip-flop 20 to give the output 14 or I<SP>2</SP>. The pulse trains 12, 15a are fed to the flip-flop 21 to give an output 13 or I<SP>1</SP>. These outputs are fed to the " and " gate 15 and the " or " gate 16, The detected output which, if synchronism is lacking is represented by 26 or 27<SP>1</SP> passes to a Miller integrating circuit 19 which provides a control voltage output depending on the time difference desired to be eliminated and this controls the reactance tube 7. To ensure correct synchronization when the drum commences rotation a second track 2<SP>11</SP>, Fig. 7, may be provided having a single mark Mto thereon. The pulse selector stage 8 then selects also a train of " zero " pulses the period of which is equal to the theoretical period of rotation of the drum. An additional control circuit 20<SP>11</SP> ,  21<SP>11</SP> ,  39<SP>11</SP> ,  19<SP>11</SP> is provided and an arrangement is described whereby the flip-flop 37 supplies control waveforms so that the first control voltage is blocked as long as the single mark does not coincide with the required origin time: When coincidence is effected the second control voltage is blocked and " fine synchronization is completed as described above. In a third embodiment (Fig. 8, not shown), one control voltage is generated by a single circuit. The reactance tube does not respond to the release signals generated by coincidence between a " zero " pulse and a pulse corresponding to the mark Mto by reason of its frequency response, but when normal operating speed is reached, a further coincidence caused by normal drum speed fluctuations releases the reactance tube to control the frequency of the pulse generator. The isolated mark Mto may be engraved on the same track and read by the same head as the equidistant control marks.
