Title: Improvements in or relating to slide projectors
Inventor: HAINY SIEGRIED
IPC: G03B23/04
Filed: 1960-12-08
Abstract: 960,710. Slide-changing projectors. KAMERA-UND KINOWERKE DRESDEN VEB Dec. 8, 1960, No. 42265/60. Heading G2J. In an optical projector having a magazine and slide-changing means means are provided for moving the magazine forwards or backwards by a pre-selected number of slide-compartments of the magazine without the intermediate slides being projected. As shown in Figs 1 and 3 a magazine 1 is driven by a reversible motor 19 via gear wheel 5 rigid with a spindle carrying a cam 7 which on rotation, tilts bar 17 to pivot a contact arm 22, rigid with spindle 18, out of electrical connection with contact 24 or 26 (corresponding to forward or backward movement of the magazine), such contact having been previously established by a preselected amount of rotation of the cam 9. Opposite rotations of the latter are selectively effected by pawl-and-ratchet 11, 13 or 10, 14, movement of the pawls being derived from electromagnets 15 or 16 selectively activated a chosen number of times depending upon the desired movement of the magazine, by depression of button switches 49 or 50. At the same time, magnets 46 or 47 are energized to cause pawls 44 or 45 to rotate an indicator disc 39 showing the number of the slide at the projection position. Continued pivoting of arm 22 under rotation of cam 9 does not change its relative position with respect to contact 24 or 26, the entire contact-carrying assembly 66 pivoting upwards on spindle 21. The preselection operation described can be made (by pushing button-switches 49 or 50 the desired number of times) during projection of a slide the circuit being thus "conditioned" via contacts 24 or 26 until operation of button switch 48 energizes electromagnet 33 to couple the drive of a motor 29 to gear wheel 31 rigid with a shaft carrying a number of cams for operating, in a predetermined order, switches 37<SP>1</SP>, 36<SP>1</SP>, 35<SP>1</SP>, and 34<SP>1</SP> to return the slide at present being projected (switch 37<SP>1</SP>), and to complete a circuit via contact 24 or 26, as the case may be (switches 34<SP>1</SP>, 36<SP>1</SP>), to effect movement of the magazine 1. When this has been completed, arm 22 has been rotated into the "normal" position and establishes a circuit via contact 25 and switch 35<SP>1</SP> to actuate the slide changing mechanism (not shown) and bring the selected slide to the projection position.

Abstract: 1,044,088. Semi-conductor devices. BOEING CO. Oct. 16, 1964 [Oct. 17, 1963], No. 42355/64. Heading H1K. [Also in Divisions G4, H3 and H4] In a data-storage device, electric and magnetic fields of suitable strengths and/or frequency of variation are applied to a semiconductor element so as to produce helical instability in an electron-hole plasma in the element. The electric and magnetic fields are mutually parallel, and the read-in means is arranged to modulate the magnetic field or the power supply providing the electric field through a range sufficient to overcome hysteresis and switch the plasma between its quiescent and helical-instability states, the read-out means being responsive to oscillations superimposed on the power supply voltage or magnetic field as a consequence of plasma oscillations. A plurality of elements having different helical-instability thresholds and corresponding plasma oscillation frequencies (the differences being caused by differences in the sizes or materials of the elements or in the applied magnetic fields) may be connected in parallel to a common power supply, the read-out circuitry including frequency-selective means. By increasing the applied voltage beyond the threshold value, the oscillation frequency of an element may be varied.

Abstract: 1,112,127. Pulse radar. SIEMENS A.G. 13 Oct., 1965 [14 Oct., 1964 (2)], No. 43359/65. Heading H4D. The invention is concerned with the opening in correct sequence of a plurality of range channels to incoming radar echo-signals. In the embodiment shown, the echo signal line 3 is connected to a plurality of range channels 1 . . . n by modulation stages M1 . . . Mn. The modulation stages are enabled in sequence by pulses from a plurality of AND gates K1 . . .  Kn. Alternate AND gates K1, K3, K5 etc. are supplied at one of their inputs with control pulses CA, Fig. 2, having a 1 :1 duty factor, whilst the other alternate gates K2, K4, K6 etc. are supplied with a 1 : 1 duty factor control pulse train CB but in antiphase with pulse train C A . The width of the pulses is equal to that of a range channel. A shift register FF is comprised of a plurality of flip-flops FF1, FF2 . . . FFn, alternate ones FF1, FF3, FF5 being triggered by shift pulses A, Fig. 2, and the other ones FF2, FF4 being triggered by shift pulses B, 180 degrees out of phase with pulses A. The arrangement is such that the output pulse from each flip-flop which is fed to the second input of the respective AND gate has a width two to three times that of the control pulses. Since the pulse output from the shift register shifts along the regster, the output of the AND gates will also shift along, and each range channel is enabled in sequence. In an alternative embodiment, Figs. 3, 4, 5, 6 (all not shown), the passage of the radar echo signal to the range channels is controlled by a relay switch Sn, Sn + 1 . . ., at the input to each channel. The relays are energized and the switches closed in correct sequence by the outputs of a plurality of shift register stages, one stage per relay. The output of a stage is also fed to the next stage, where it is lengthened to form a pulse analogous to the pulse output of one of the flip-flop stages of the first embodiment. Each stage comprises an AND gate, which is fed with the just described pulse, and a 1 : 1 duty factor control pulse, to provide the shifting output pulses for the relays.

Machines with types upon spherical surfaces.- A typewriter of the type having a single element printing head 2, Fig. 3, mounted on a carrier 3 for sliding movement on a bar 4 by flexible cables 6 and 12, wrapped about pulleys 10 and 16 for rotation with shaft 11, is provided with a plurality of character keys and one or more special mark keys 1, Fig. 1, in which an escapement mechanism is actuated by depression of each of the character keys, the escapement mechanism being disabled by a compound linkage when one of the special mark keys are depressed. Letter-spacing mechanism.-When the character key 1, Fig. 1, is depressed a fluted shaft 60 is caused to rotate 180 degrees counter-clockwise causing a cam 58 to pivot a member 56 about a pin 45, so as to swing upwardly a bent portion 52, of an interposer 50, resting on a stepped portion 62 of the member 56, to thereby pivot counter-clockwise an arm 54 on a member 44 and displace a link 43, Figs. 1 and 4, longitudinally, which through a member 33 urges a lever 29 in a downward direction to pivot a bail plate 28 in a clockwise direction, which in turn rocks a bail 24 to engage a projection 26, Fig. 3, on a dog 20, and disengage the dog from teeth 22 of the bar 4 and effect escapement of the carrier 3. Accenting arrangements.-On depression of a special mark key 1, Fig. 1, a member 88 depresses an interposer 78, supported both for pivotal and longitudinal movement by a pin 79, whereupon the actuated fluted shaft 60 engages a heel portion 84 of the interposer 79 to pivot a rod 75 in a clockwise direction, to which is connected an arm 91 acting against an elongated member 91 connected to the interposer 50 to move it relative to the pin 45 to disengage the bent portion 52 from the arm 54 (Fig. 2, not shown). As the cam 58 rocks the member 56, no escapement takes place since the bent portion 52 is no longer between the arms 54 and 61. Having typed the special mark any key lever for another character to be typed under the mark may be depressed and the escapement, which meanwhile has been re-set, will be actuated in response to the actuation of the latter key. Specification 873,920 is referred to.
