Title: Device for testing the interrupter of the primary circuit of internal combustion engine ignition circuits
IPC: F02P17/00
Filed: 1934-07-09
Abstract: 430,388. Ignition-interrupter indicator and tester. WEIDENOFF, J., 4352, Roosevelt Road, Chicago, U.S.A. July 9, 1934, No. 20134. [Class 7 (iv)] Apparatus for visually indicating on a graduated dial the angle of closure of the contacts of the primary circuit interrupter comprises a motor-driven shaft 10 having a chuck 28 to which the interrupter cam - shaft is secured, supporting means 32 for holding the non-rotating body of the interrupter, an angularly adjustable graduated dial 37 and a neon tube 42 secured to the rotating shaft. Set in the base of the dial support 35 is a collecting ring 38 which is in series with a source of current, with the interrupter contacts under test, and, by way of a brush 44, with the neon tube 42 ; the metal finger 39, the end of which is adjacent to the earthed dial 37 completes the circuit. The extent of cambreaker engagement, its continuity and uniformity are shown by the illuminated band obtained as the neon tube passes over the dial 37. The illumination is visible only through a narrow slit in the holder. For interrupters having more than one pair of contacts, tubes of differing colours are used mounted on arms which are relatively and angularly adjustable about the shaft 10. The mountings of the breakers relatively to each other may then be set precisely by observation of the colour bands obtained on the indicator dial. Fixed annular neon tubes may be used, observation being made of one or more slits in a rotating disc mounted on the shaft 10 over the tubes. Distinct bands are ensured by placing the slits at different distances radially from the shaft. Direct or rectified current may be supplied to annular tubes through thermionic valves, to the grids of which the interrupters are connected. As the grid circuits are made and broken, variations in illumination are given corresponding to the angles of contact.
Patent GB-577384-A (GB)
Title: Terpene resin
IPC: C08F36/00
Filed: 1943-12-02
Abstract: A terpene resin is made by bringing a turpentine liquid containing a higher proportion of b -pinene than is contained in any turpentine as originally produced, with agitation and under heat-abstracting conditions, into contact with a polyvalent metal halide which is capable of hydrolysis by water to give an acid reaction, e.g. aluminium chloride, stannic chloride, antimony pentachloride or ferric chloride.  b -Pinene may be isolated from gum spirits of turpentine by fractionation and polymerized at 30-40 DEG  C., if desired, in the presence of an inert hydrocarbon diluent such as mineral spirits.  The reaction is stopped by addition of dilute hydrochloric acid and the catalyst in the water layer separated.  The solvent and heavy oil are distilled off to leave the solid resin. Alternatively, gum spirits of turpentine are enriched with b -pinene and similarly treated.

Title: Apparatus for detecting leaks in hollow bodies
IPC: G01M3/26
Filed: 1974-05-07
Abstract: 1472474 Leak testing SOC ANON DES USINES CHAUSSON 7 May 1974 [11 May 1973] 20171/74 Heading G1S To leak test hollow bodies such as vehicle radiators, a machine is provided which comprises a rotary table 21 supporting a series of units P 1 - P 1  8  each comprising supports for a body 33 under test and a similar reference body 30, means for supplying compressed air to both the test and reference bodies, a manometer 28 for sensing any difference in internal pressure between the bodies 30, 33, and controlling means such as a set 22 of fixed arcuate contacts a 1  - a 7  concentric with a shaft 4 which drives the table 21 and cooperating with a set of contact brushes 24 of each unit which rotate with the table to control, via a series of valves EV, the operation of the machine. Machine operation is also controlled by contacts such as M4 mounted at each unit below the table 21 and engaging one or more fixed cam tracks 26. Dry and lubricated air is supplied to the units by respective pipes 14, 15 passing through the centre of the hollow shaft 4 and communicating with manifolds 17, 17a and 19 which also rotate with the table. In operation air from manifold 17 is fed to a valve EVA controlled by a contact M3 operated when the body 33 under test is manually pushed over an air supply tube 48. On operation of contact M3 valve EVA operates the jaws of a gripper 47 to hold one pipe 33a of the body 33 around the tube 48, any other inlets to the body 33, such as pipe 33b, being closed simultaneously by a cap 66 operated manually or by jack 67 controlled by a valve EVI. The outlet of valve EVA also controls, via valve EVB, jacks V 2b  and Via which respectively compress or expand a packing 56 around the tube 48, and withdraw the tube 48 from pipe 33a after testing. A similar system simultaneously connects the reference body 30 with an air supply, and valves EVC, EVH, controlled by valve EVB via valve EVD, subsequently connect the reference body 30 with one inlet 77b of the manometer 28 and the body under test 33 with the other manometer inlet 77a. Should a leak in body 33 exist, liquid rises in the manometer limb 85a and cuts off light from a source 90 to a photo-cell 91 to signal a relay (92) controlling parallel switch circuits (93), (93a), Fig. 9 (not shown) which act as memories. Contacts M 1 , M 2 , included in these circuits, then cause leaky bodies 33 to be dropped on to a 'reject' conveyer (61) and fluid-tight bodies 33 to be dropped on to an 'accept' conveyer (62) as in Fig. 5 (not shown). As in Fig. 3 (not shown) the jack V 1  may control a lever (63) to operate a marking device such as a paint gun 64 in order to mark fluid-tight bodies.

Title: Improvements in and relating to television and the like transmission systems
IPC: H04N5/073
Filed: 1933-07-19
Abstract: 422,710. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd., Blyth Road, Hayes, Middlesex, MANIFOLD, M. BOWMAN-, Heathcot, Worplesdon Station, Surrey, and PERCIVAL, W. S., 6, York Mansions, York Avenue, Hanwell, Middlesex. July 19, 1933, No. 20393. [Classes 40 (iii) and 40 (v)] The synchronizing-circuits of a condenserdischarge oscillator controlling a cathode-ray television receiver are protected from atmospherics by means of a voltage-limiting device. The synchronizing impulses cause the condenser 17, Fig. 4, to spill over through the valve 12, but their amplitude is such that they can only take effect when the potential of the control grid 41 has nearly reached the full value to which it approaches during the charging of the condenser 17. In order that the effect of atmospherics may be similarly restricted their amplitude is limited either at 26, 27, Fig. 4, in the line-frequency stage, or at 35, 36, Fig. 5, in the radio-frequency stage. Producing saw-tooth wave-form. When valve 12 is blocked by a charge on the control grid 41 the charge gradually leaks away through resistance 14. When current begins to flow in the anode and screen-grid circuits 16, 42, the coupling 10, 15, produces a rapid breakdown so that the condenser 17, which has meanwhile being acquiring a charge gradually, discharges rapidly through the valve. A similar effect in the opposite direction subsequently ensures a sudden termination of the discharge. Eliminating the effect of strays by voltagelimitation. Line-synchronizing signals on a sub-carrier are filtered at 2 from the picture signals. The sub-carrier is rectified at 5 and filtered at 7, 8, 9, from the framing signals which are taken off at 25. They are then applied to the grid 41 at a moment when it has lost so much of its negative charge that the signal is able to initiate the discharge of condenser 17 through the valve. In order that the effect of atmospherics may not be strong enough to initiate the discharge, the grid circuit is shunted by a copper-oxide rectifier 26 in series with a battery 27, so arranged as to constitute a voltage-limiting device. In a modification, Fig. 5, a voltagelimiter made up of a diode and battery or a pair of diodes 35, 36 with batteries 37, 38, is arranged to limit the amplitude of the radio-frequency impulses applied to the amplifier 31, picture signals (represented by decreases of amplitude) being taken off at 3, 4, while framing signals and line-synchronizing signals are taken off at 25, 40, after detection by valve 39. The voltage-limiter ensures that atmospherics shall not be strong enough to cause a serious loss of synchronism. The Fourier components of the synchronizing signals may be restricted by means of a lowpass or band-pass filter 40. The invention is distinguished from that disclosed in Specification 419,441.
