Title: An arrangement for the electro-magnetic recording of letter and like signals
IPC: H04L21/00
Filed: 1933-10-10
Abstract: 427,257. Copying-telegraphy. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Oct. 10, 1933, No. 27953. Convention date, March 24. [Class 40 (iii)] In a receiver of the Siemens - Hell type, the signals conveyed by an audio-frequency carrier are applied to an alternating- current recording- magnet without previous rectification. Keyboard transmitter. The transmitter comprises a set of cam discs 5, Fig. 2, which are selectively released for rotation by depression of the keys 6. Depression of any key locks the remaining keys except during the last quarter-revolution of the cam, when a long spacing signal is being sent to line. Depression of a key brings an interponent 7 into position between the relevant cam disc and the transmitter contacts 7<a>. Receiver. The shaft 8, Fig. 3, makes 12 revolutions for each letter, and as long as a printing impulse is being received the magnet 10 presses the straight edge 12 against the spiral carried by the shaft, causing a vertical line to be drawn. According to the invention, the carrier current, which has a frequency of 800 cycles per second, is not rectified, but is applied to a " phase relay " having two coils M1, M2 with unpolarized cores, a condenser C2 being connected in series with M1 so that the arm M1, C2 is tuned to the signal frequency ; moreover the dimensions are such that the currents in coils M1, M2 are approximately in quadrature and produce equal pulling-forces. The anode circuit as a whole resonates at the signal frequency, and the condenser C1 may be tuned to produce this result or, if it be a large fixed condenser, a small tuning condenser C4 may be connected in series with it. Since the tuning is affected by the position of the armature of the relay, the circuits are tuned with the armature in the attracted position or the released position according as a strong printing-pressure or a rapid pull-up is the more desired. The armature S may carry contacts for controlling subsidiary circuits such as that of a sluggish relay for cutting out the motor.

Abstract: 784,405. Pneumatic conveyers. BLAW KNOX, Ltd. Sept. 29, 1955 [Sept. 29, 1954], No. 28147/54. Class 78 (1). In a storage bin for handling pulverulent materials the material rests on a sheet 11, Fig. 1, of foamed rubber latex which is,supported by a perforated plate (not shown) of metal or other rigid material and below which is a chamber 15 to which air under pressure can be supplied. The sheet 11 assumes a domed shape when air is admitted to the chamber 15. When this occurs its pores are opened or expanded so that air passes freely therethrough to fluidize the material. The metal support may be replaced by pervious material, e.g. hessian, bonded to the rubber. In a modification the material rests on a series of strips 16, Fig. 2, of foamed rubber latex which is clamped between partition members 17 and underlying tray elements 18 to form chambers 19 to all, or any selected one, of which air can be supplied. In another modification the trays are replaced by corrugated material.

Title: Improvements relating to the manufacture of pneumatic tyres
Inventor: DRAKEFORD GEORGE EDWARD
IPC: B29D30/36
Filed: 1958-09-03
Abstract: 922,463. Shaping tyre carcasses. DUNLOP RUBBER CO. Ltd. Aug. 25, 1959 [Sept. 3, 1958], No. 28244/58. Class 144 (1). A float band pneumatic tyre carcass 6 is shaped by moving its beads 8 axially towards each other whilst radially expanding the carcass between the beads, the radial expansion being constrained initially only to the crown portion 9 and the constraint gradually eased as expansion proceeds to permit the region of expansion to increase towards the beads. As shown, the beads 8 are seated in angle-section rings 1 at the ends of an inflatable cylindrical rubber diaphragm 4, and a pair of constraining rings 11 surround the carcass for respectively opposed axial displacement relative to the radial plane of symmetry of the carcass. Each ring 11 has an inner periphery 12, slightly larger in diameter than the beads 8 and rings 1, which joins via a convex constraining surface 16, into a concave carcase shaping surface 15. The surface 15 terminates in a radial surface 14 leading to the outer periphery 13 of the ring 11, the surfaces 14 of the two rings abutting in their closed initial constraining position, Fig. 1, and the peripheries 13 being recessed at 19 to define, in the shaping position of the rings 11, Fig. 5, a locating recess for an inextensible annular breaker 20. In operation, the rings 11 are moved apart simultaneously with the mutual approach of the bead supporting rings 1, during inflation and radial expansion of the diaphragm 4, the carcass 6 engaging the surfaces 16 of the rings 11 and expanding only therebetween. To reduce friction, air jets 18 extend through the rings 11 to the surfaces 16. After final shaping of the carcase, Fig. 5, the breaker 20 is located in the recesses 19, and a tread strip 21 is centred thereon, by means of markings on the peripheries 13 of the rings 11. The rings 11 are then withdrawn to permit consolidation of the breaker and tread on to the carcass. The rings I and 11 are rotatable about their common axis to facilitate location and consolidation of the breaker and tread strips. To facilitate rolling of the beads 8 on the rings 1 during shaping, each ring may carry an inflatable bead-seating tube 22, Fig. 6, which may serve also to seal the beads to the rings and thus permit the diaphragm 4 to be omitted.

Filed: 1921-10-25
Abstract: 188,915. Wright, E. Oct. 25, 1921. Breaking and scutching apparatus.-In apparatus for separating the fibrous parts of stems or leaves from the pulp and woody parts in which a spiked drum is employed, the pins of which are cleaned by bars moving up and down them during the rotation of the drum, in order that both sides of the material may be scraped simultaneously each cleaner bar E is fitted with a reversible strip F having scraping edges. The pins are mounted on slats C on the drum B and project through the strips F. The cleaner bars are controlled by an eccentric guide J rotating with the drum. A star wheel G having arms I provided with scraping edges H co-operates with the drum, each arm in its rotation engaging a slot on the drum intermediate of two rows of teeth. The material is thus pressed into the teeth and bent to engage the edges of two bars on one side and the edges H on the arm I on the other side. The inside edges of the strips F will cut and release any waste material between the bars and the drum.

A device for damping the fall of a fuel element in a reactor fuel channel comprises a closed deformable container placed in the channel. Core support plate 16 carries moderator brick columns 10 keyed by keys 12 to define the fuel channels 8. The moderator is supported by bearing 14 and the fuel elements by shoulder 22 of coolant gas guide cone 20 retained by screws 18. Above dummy fuel element 34 is the first fuel element 38 supported in a tube 42 by a spider 40 and flow splitters 44. If such a fuel element is dropped, it will tear free of its mounting tube and pass downwards into catchpot 26 until it strikes the container 46, e.g. stainless steel, containing powdered graphite 48. Deformation of the container 46 absorbs kinetic energy, as also may stretching of the catchpot 26 in the region of its slots 50. The container 46 may be replaced with an equivalent depth of shorter containers. A number of alternative catchpots are described (Figs. 2 to 7, not shown) which provide for further energy absorption; thus, Fig. 2 shows shearing washers (52) placed between abutting shoulders 22 of Fig. 1; Fig. 3 shows a sleeve (54) placed between catchpot 26 and plate 16 to prevent the shearing washers joining the catchpot in the channel; Figs. 4 and 5 illustrate a scoring ring form of energy absorber, and Figs. 6 and 7 show a deformable taper sleeve.

The inlet pressure may be varied automatically or by hand by the throttle valves 12. The motor exhaust passes through the pipe 11 to one side of a piston 23, Fig. 6, having in an extension a bore 21 which controls the outflow and so the discharge pressure, while the other side of the piston is subject to the air inlet pressure through a pipe 27. The spaces 14 at the rear of the compressor pistons may be loaded with a variable pressure by connection with the inlet or outlet pressure during the whole or a part of the stroke, e.g. by the conduit 17 having a port 16 controlled by the piston.
