[Also in Division F2] Paper, or other material to be printed on, is held by suction on a table or other support comprising a perforated plate 10, a core 6 of corrugated or honeycomb material, a support 4 and a peripheral wall member 11. The core 6 provides a plurality of spaced passages 9, through which air is withdrawn, extending normal to the support 4 and communicating with perforations 2 in plate 10. Lateral passages 12, cut, sawn, drilled or milled in the core 6 either against plate 10 or where it rests on support 4, join the passages 9 to an aperture in support 4 and to suction conduit 3. Alternatively the paper may be held by suction during printing on a cylinder having a supporting inner cylinder, covered with radial corrugated or honeycomb material with lateral passages in it, and a perforated cover. A preferred form of core 6 is made up of alternate pieces of flat and corrugated material. Preferably the table or cylinder is of sheet metal such as steel or aluminium, but paper, paperboard or cardboard, plastics materials or wood may be used. Assembly may be by welding, soldering, brazing or cementing and in making the cylinder honeycomb or corrugated material may be wrapped about the inner cylinder.

Filed: 1963-12-05
Abstract: 1,114,245. Automatic exchange systems. GRANLEY PRODUCTS (LONDON) Ltd. 3 Dec., 1964 [5 Dec., 1963], No. 48178/63. Heading H4K. In a device for automatically dialling a number and reporting the detection of a burglary or fire a discriminating circuit responds to a signal from a record to connect a line-holding zero impedance link across the line while a dialling contact controlled by the record is being operated. As shown the alarm is initiated by a push button 11 or a detector circuit (not shown) which applies a potential difference at 12. A relay A/3 operates closing a latching contact A1, connecting the system to line through contacts A2, A3 and connecting power to a tape drive M. Dialling and message signals after pre-amplification at 21 are amplified by transistors T 1  and T 2 . The message signals are connected to line through a transformer 16 and the 1 kc.dialling signals filtered out at S 1 , C 5  are applied, to a relay B/2 having a dialling contact B1 and through C7 and R10 to a discriminator circuit comprising a transistor T4 biased as a threshold device and an amplifier incorporating a timing circuit C10, R14. The discriminator responds to the reception of a dialling signal and operates a relay C/1 moving its contact into engagement with a fixed contact C 1B  removing any impedance offered to the line and breaking a short circuit for the dialling contact B1 allowing it to effect the connection. When the last digit has been read from the tape the signal level as read from the tape drops to a level insufficient to operate the discriminator and thus the relay C. The relay C drops out shorting the contact B1 and connecting the output winding of the transformer 16 to line. An end of message detector comprising a capacitor C12 which takes 15 seconds to charge and is discharged to delay switch off, by contact B2 every time the relay B detects a 1 kc. component in the message, operates a relay E to switch off the apparatus after transmission.

[Also in Division H1] In electron beam-welding or soldering using an interrupted beam, each beam pulse reaches a power density sufficient to penetrate deeply the metal being heated during a period which is short relative to the pulse duration and the decay time of each pulse is long relative to the pulse duration. The time taken for a pulse to reach peak power may be relatively short or long but does not exceed the decay time. The peak period is 1/100... 1/10 of the pulse duration and the pulse spacing is 10 ... 100 times the pulse duration. The pulse duration is less than 0.01 sec. Various pulse forms having linear concave or convex leading and trailing edges and flat peaked or curved tops are described. The process can be used for seam or spot-welding and the beam can be oscillated along or transverse to the weld or can be moved in a circular path.

A cine projector of the kind disclosed in Specification 1, 107, 719 has an added mechanism and control circuit by which the claw feed may be rendered inoperative for predetermined periods, to permit still projection, by means responsive to code marks on the film. Remote control for forward and reverse operation is achieved by a solenoid 120 which shifts lens 94 independently of manual control knob 74 to axially displace drive shaft 24. Still and motion projection are remotely controlled by solenoid 122 which shifts arm 132 to a position where the end 134 prevents the follower 54 on claw arm 36 from engaging depressions 70, 70<SP>1</SP>, or 70<SP>11</SP> in the in-andout face cam 64. The timing for energization of solenoid 122 is synchronized with the claw positions by lobes on cam 64 which trip switches in the solenoid circuit. Lens 16 is refocused for still projection by an arm 186 which engages and is shifted by the arm 132. The solenoids are selectively energized by transistorized control circuits which are activated by signals from a photo-cell and lamp system which senses the presence of transparent or opaque coding spots in the film margin. An electronic re-set or start circuit is provided comprising an n-p-n transistor operating as a solid state switch triggered by a monostable multi-vibrator including two p-n-p transistors. A timing circuit controlling the reset circuit comprises two logic stages including two transistors, a switch and a blocking oscillator, and operates to provide a fixed duration of the still projection. The solenoid switches may alternatively be mannually operated. Reference has been directed by the Comptroller to Specification, 1,054,105, 1,054,106, 1,107,718 and 1,107,719.

The guns having servo-control means 8, are to be trained on to an aim-off point Ffp, Fig. 5, adjacent to the flying- target in response to signals from the instrument centre. The instantaneous position of the target in relation to the position of the instrument centre 4 is continuously determined in a calculating unit 4a, Fig. 6, in the instrument centre 4 which also calculates the aim-off point Ffp, Fig. 5. The instrument centre 4, Figs. 1 and 2, is spaced from the guns 1. The aim-off point Ffp, Fig. 5, is so calculated that it constantly coincides with aiming-point Fp of the targettracking sight when the latter is directed on to the target. The simulated firing is by each gun discharging laser pulse trains 29, Fig. 9, one train for each firing of a gun and each containing a pre-determined number of laser pulses 30. The pulse trains 29 are of a shorter duration than the time between two consecutive firings and, upon striking the target, are reflected back to the gun from which discharge took place. The hit result is determined by the number of laser pulses received from the target. A constant projectile flight time ts. Fig. 6, which is set at zero, is inserted in the calculating unit 4a. Each gun is provided with a laser transmitter 24, Fig. 8, and a laser receiver 26 having their optic axes parallel with the barrel 9 of the gun. The target is provided with a reflecting device 31, Fig. 2. The laser receiver 26 is provided with a detecting unit 33, Fig. 8, which records the number of pulses reflected from the target and which, provided the number is equal to or exceeds a pre-determined minimum value, transmits a signal to a hit-recording logic unit 34, Fig. 2, a signal lamp 35 and a buzzer 36 which are mounted on the gun as shown in Fig. 7.
