Title: Corrugation forming dies for metal plates
IPC: B21D13/02
Filed: 1924-07-30
Abstract: 233,935. Connery, W. M. July 30, 1924. Corrugating; dies.-In a machine by which single corrugations are formed in thick sheets by drawing the sheet in from both sides by the coaction of a fixed and movable die, (1) considerable clearance is allowed between the sheet and the fixed die in order to allow for inequalities in the thickness of the sheet, (2) projecting beads on the fixed die compensate for different degrees of hardness in different parts of the sheet, and (3) means are provided for regulating and equalizing the angle that the adjacent parts of the sheet make with the corrugated part. A girder 1 carrying a die 11 is raised relatively to a fixed head 19 carrying a forming-blade 21 and side abutment members 23. The blade forces the sheet downward into the recess by drawing it inwards on both sides over the upper bevelled edges of the reversible facing bars 13. Considerable clearance is allowed between the inner surface of the sheet and the sides of the blade. The blade comprises a lower tapered portion 26, and an upper parallel portion provided with curved beads 27 of such thickness that continuations of the tapered portion 26 would be tangential thereto. The tapered portions 26 preferably are parallel to the bars 13. The beads 27 act to overcome the different hardnesses of different parts of the sheet, while the final position of the abutment members 23 relatively to the upper edges of the bars 13 determines the final slope of the portion of the sheet adjacent to the corrugation. Several movable dies may be bolted end to end and used with a single fixed head and blade. Specification 202,381, [Class 25, Chimneys &c.], is referred to.

Title: Improvements in and relating to modulating circuits
Inventor: MORRIS RICHARD MICHAEL
IPC: H04Q11/04
Filed: 1966-04-26
Abstract: 1,132,029. Automatic exchange systems; switching circuits. GENERAL ELECTRIC CO. Ltd. 26 April, 1967 [26 April, 1966], No. 18223/66. Headings H3T and H4K. Loop current is supervised by a saturable core 9 which is saturated by windings 7 and 8 when the loop is off-hook, a transistor 15 with core windings 14 in its load circuit being fed with scanning pulses at the frame frequency of a P.C.M. channel switching system, interruptions of the loop produced by dialling impulses causing the core to present the transistor 15 with corresponding increases in load impedance. The output circuit comprises a normally conducting transistor 22 with a normally conducting Zener diode 21 reverse biased to breakdown in the base circuit of 22. Current over diode 21 drops a voltage across resistor 18 to normally back bias a diode 17. If the loop is off-hook scanning pulses find a low load impedance over transistor 15 and a large voltage appears across resistor 16. Diode 17 consequently conducts allowing Zener diode 21 to recover from breakdown and causing transistor 22 to cut off. With a loop disconnect impulse present a scanning pulse finds a high load impedance associated with transistor 15 and only a small voltage change occurs across resistor 16. Diode 17 in these circumstances remains back biased, Zener diode continues in a broken-down condition and transistor 22 remains conducting.

Abstract: 1,216,767. Hose couplings. C. K. WALTHER, [trading as CARL KURT WALTHER]. 18 April, 1968, No. 18407/68. Heading F2G. A device for the simultaneous connection of a plurality of separate hose-pipes comprises a pair of carrier plates 10 and 3 in which a plurality of spigot-and-socket hose-pipe coupling halves are respectively secured by circlips 11 and 12 to permit radial play of the spigot and/or socket halves in their respective plates, and at least one locking unit 7 detachably connecting the plates and including a locking plug 17 secured to plate 10 and releasably retained in a socket secured to plate 3 by balls 24 carried by the socket and engageable in a groove 35 in the plug. The balls are releasably retained by a spring- loaded sleeve 23, which is mounted on a plate 6, the balls being released by squeezing handgrips 4 and 5 on the plates 3 and 6 together to retract the sleeve past a ball detent 26 thereby permitting separation of the carrier plates and their respective coupling halves. In a modification, Fig. 5 (not shown), the hand grip 4 is dispensed with, the plate 6 being pulled back to release the balls and the sleeve 23 being held in the retracted unlocked position by a spring-urged follow-up plunger 30 on uncoupling of the carrier plates and the hose couplings. The hose couplings comprise a high-pressure group 1 and a low pressure group 2, the latter being asymmetrically arranged to ensure correct coupling. Alternatively, a pin and hole may be provided between the carrier plates to avoid incorrect coupling. The spigot halves of the couplings are each provided with a sealing ring 9 seated in a peripheral groove.
