Title: Improvements relating to networks for generating pulses of electrical energy
Inventor: WILKINSON KENNETH JAMES RAWCLI
IPC: H03K3/53
Filed: 1955-05-12
Abstract: 792,641. Generating high-frequency oscillations. BRITISH THOMSON-HOUSTON CO., Ltd. May 12, 1955, No. 13776/55. Class 40 (5). When the condensers of a Marx-type pulse generator are discharged in series a damped train of high-frequency oscillations is applied to the load, the condensers being connected together by inductances to form, with the load capacitance, an oscillatory circuit resonant at the desired frequency. The generator comprises a ladder network of shunt condensers Cl ... Cn and series inductances L1 ... Ln, and L<SP>1</SP>1 ... L<SP>1</SP>n, charged from an alternating source S through a regulating autotransformer 10, a step-up transformer 11 and an inductance 12. The condensers discharge in series through spark gaps G1 ... Gn the adjustment of which is mechanically linked with that of the adjustable taps on transformer 10. The condensers and inductances together with the load capacitance Cl form a resonant circuit. To cause the condensers to discharge at a voltage crest of the applied potential, the first two gaps G1, G2 are provided with triggering electrodes 14, 15 as described in Specification 580,003, [Group XL], and energized through transformers 18 from a thyratron 17 fired by a peaking transformer 16 in the charging current circuit. Resistors 20 are connected in series with the spark gaps to control the discharge, their damping effect being limited by shunt inductances 21 affording a low impedance by-pass at the oscillatory frequency. The network is caused to resonate at the input power frequency as described in Specification 578,875, [Group XL]. Specification 351,436, [Group XL], also is referred to.

Title: Conveyer apparatus including mechanism for turning over articles
Inventor: JOHNSON JOHN ARTHUR
IPC: B05B13/02
Filed: 1954-05-12
Abstract: <PICT:0783182/III/1> Articles of flat ceramic ware which have been sprayed on one face while travelling on a conveyer consisting of a plurality of parallel endless wires (not shown) are turned over to present their other faces for spraying by a wheel which consists of a number of slotted discs 20 arranged between the wires, and which is rotated through part of a revolution about an axis transverse to and just above the plane of the wires in response to an article entering one of the slots and contacting the operating lever 39 of a switch 38.  Closure of switch 38 by the article energizes a solenoid 37 controlling a valve 36 which thereupon supplies compressed air to the lower end of a cylinder 31, extending its piston rod to move a pawl carrier against the damping action of an oil-filled damping cylinder 34.  A pawl 26 on the pawl carrier turns the discs 20 through a ratchet wheel 25 through one sixth of a revolution to brng the next series of slots into position for receiving an article.  At the end of the movement an abutment 40 on the piston rod of cylinder 34 operates a switch 41, de-energizing solenoid 37 to re-set valve 36 whereby air is exhausted from the lower end of cylinder 31 and admitted to the upper end to return the parts to their original positions in preparation for the receipt of another article.  A spring-loaded catch 28 prevents backlash in the ratchet mechanism. After three such movements the first-received article is deposited back on to the conveyer wires, in inverted position.

Title: Multi-layer light-sensitive photographic material
IPC: G03C1/805
Filed: 1937-05-19
Abstract: 481,702. Photographic multi - layer material. GEVAERT PHOTO - PRODUCTEN N. V. May 19, 1937, No. 13953. Convention date, May 19, 1936. [Class 98 (ii)] A multi-layer lightsensitive material comprises between the light - sensitive layers, at least one non-sensitive layer having a melting point which is between the temperature at which a light sensitive layer can be applied, and the temperature at which a light sensitive would be damaged. Intermediate layers of different melting points are used, and are preferably arranged so that melting points rise in the direction of top to bottom of the material. As fusible materials there may be used waxes, paraffin wax, fatty substances, natural and artificial resins, the intermediate layers being of 2-3 microns thickness. The fusible material should preferably have a refractive index nearly identical with that of the colloid of the light-sensitive layer. In the example described, upon a support T of glass are mounted three layers R, G, B sensitive to red, green-yellow and blue respectively. Between R and G is a layer a of paraffin wax of melting point 70‹ C. Between layer G and B there is a thin paraffin wax layer b having a melting point of 40‹ C. Yellow and red filter dyestuffs may be added to the layer b and a respectively. After exposure, the layers are separated and brought onto transparent supports of similar nature to the layer T. The moistened gelatin layer of the support is pressed onto the layer to be separated, and heated to a temperature just above the melting point of the wax. Material of three or more layers may be separated in this manner.

Title: Improvements in electric cut-out or protective apparatus
IPC: H02H7/085
Filed: 1949-05-26
Abstract: 662,001. Protective cut-out arrangements; thermal switches. EVENDEN, E. F., and P. & B. ENGINEERING CO., Ltd. May 25, 1950. [May 26, 1949] No. 14115/49. Class 38 (v). A protective arrangement for an A.C. motor liable to stalling comprises two thermal devices each actuating a contact in response to different functions of the same phase current, the two contacts engaging to trip the circuit-breaker of the motor circuit under locked rotor conditions. The protective device, Fig. 2, comprises two thermal units A, B each having a bimetallic coil 14 fixed at its inner end and connected at its outer end by an insulating bridle 16 to the outer end of a bimetallic coil 15. The inner end of each of the latter coils is secured to a hub rotatable on a spindle 19 and carrying a contact arm 25 with contact 26. The coils 15 respond to changes in the ambient temperature and the coils 14 are heated by the current flowing through them or by adjacent heating coils. The bimetallic coil 14, Fig. 4, of unit A is energised directly by a current transformer CT in the circuit of motor M, whilst the coil 14 of unit B is supplied from the secondary winding of a saturable core transformer 30 through a variable resistor 31, the primary winding of the transformer 30 being connected in parallel or as shown, in series with the coil 14 of unit A. Under normal load conditions and overloads the thermal units move their arms 25 in the same direction through substantially equal angular movements so that the contacts 26 remain open. If the motor fails to start, or if running, stalls, the excessive current taken by the motor results in the saturation of the transformer 30 so that the current in coil 14, unit B, does not increase proportionally as the current in coil 14, unit A. Thus the arm 25 of unit A rapidly overtakes the arm 25 of unit B, closing the contacts 26 to energise the trip coil of the circuit-breaker CB. The Provisional Specification refers to Specifications 370,543, [Group XXXVI], and 577,092.

Abstract: 1,003,075. Radiation sensitive fire alarms. THRING'S ADVANCED DEVELOPMENTS Ltd. April 9, 1964 [April 11,1963], No.14599/63. Heading GIA A fire alarm includes a detector 17 with a filter 18 capable of giving an electrical output in response to radiation in the 2-7 micron region and a rotary scanner serving to direct on to the detector in sequence radiation from sections of the space to be protected. As shown the scanner consists of a curved mirror strip 12 mounted on a drive shaft 10 for rotation, either directly or through gearing, by a motor 5. Thin ribs 15 position, the detector and also support a thin infra-redtransparent protective globe 19. Opaque material may be stuck on the globe to prevent operation of the alarm by, for example, a fixed electric fire. Provision may also be made to exclude direct sunlight and the globe may be opaque to visible light. It is contemplated that one or more units should be mounted overhead to cover the required space, the rate of scanning being between 1 and 10 revolutions a second. If a fire breaks out the output of any unit viewing the fire will include pulses at the rotation frequency which can be used to initiate operation of an audible and/or visual alarm. Each unit may include means producing low amplitude pulses at each rotation, and pulses being used to indicate correct rotation of the scanner. To prevent a uniform but dangerous rise of temperature in the space protected fairly to give an alarm it is proposed to fit a blanking element covering a small arc and driven at a different speed of revolution to the scanner so that the position of the blind spot varies.
