Patent GB-453406-A (GB)
Abstract: 453,406. Engine stop-gear. BURSCHKIES, H.-W., 27, Sch³tte-Lanzstrasse, Lichterfelde-Ost, Berlin. March 7, 1936, Nos. 6928 and 6929. Convention dates, April 2, 1935 and Feb. 15, 1936. [Class 122 (iv)] An internal-combustion engine employing oil lubrication is stopped by short-circuiting the ignition current which passes between spaced terminals housed in the lubricating-system which are normally insulated by the oil resistance. Failure or deterioration of the oil results in a spark and stoppage. In the construction shown in Fig. 1, an insulating body 2 is mounted in a socket 1<a> on an earthed oil conduit 1 and carries a pin 4 which projects into the conduit, and is connected through a cable 4a to the high-tension ignition circuit of an internal-combustion engine. The insulating resistance of the oil normally prevents sparking. The absence of oil, or a change in its constitution results in a short-circuit and the stoppage of the engine. In a modification a conducting-rod connected to the ignition circuit passes down an insulating- body in an earthed container provided with a second adjustable electrode. Should the device be tilted, as in an overturned motor-cycle, a spark jumps and short-circuits the engine. An oil-dip stick or measuring-rod is shown in Fig. 2. A metal wire 9 connected to the hightension cable 16 is mounted in an insulating-rod 8 surrounded by a metal tube 7. The rod may be fixed in an engine casing 14 by means of a bush 13. If the oil level A-B falls, or the oil deteriorates, air penetrates the tube 7 below the line C-C through the slots 15 and results in sparking and the short-circuiting of the engine.

Title: Sheet metal shearing machine
IPC: B23D35/00
Filed: 1966-10-12
Abstract: 1,106,680. Shearing. MASCHINENFABRIK SACK G.m.b.H. 12 Oct., 1966 [12 Oct., 1965], No. 45579/66. Heading B3W. A sheet metal shear comprises a stationary blade, a movable blade and a hold-down, the movable blade being guided for sliding movement parallel to the cutting plane in a slide on which the hold-down is mounted and which slides in a guide, in a direction parallel to the line of cut, but inclined to plane of cut and is driven through a frictional connection so that during a shearing operation the slide moves until the hold-down engages the work, thus setting the clearance between the blades and then the movable blade moves relative to the slide to make the cut. The shear frame 10 provides mountings for the stationary blade 11 and a crank-shaft 17 which has an eccentric 16 connected by a rod 15 to the movable blade carrier 13. Guides for the carrier 13 are formed in a slide 19 on which the hold-down 21 is mounted. The slide 19 runs in guides formed in the frame 10 and inclined at an angle to the plane of cut. The hold-down is moved into engagement with the work by a cam 32 secured to the crank-shaft and which co-operates with a roller 30 mounted on lever 26. The hold-down slide 19 has lugs 22 which support a pivot pin for the lever, the left hand part 24 of which bears against the top of the hold-down slide and the right hand part of which is pivotally connected at 27 to an hydraulic ram 28. Operation.-With both the slides 19 and the blade carrier 13 in the raised position as shown in Fig. 1, the cutting clearance between the blades is at its maximum. At the beginning of the shear cycle both the slide and blade carrier move down together, until the hold-down contacts the work. The clearance between the blades will then be proportional to the thickness of the work. The blade carrier then moves vertically in the now stationary hold-down slide to effect the cut. As the cam 32 continues to rotate the hydraulic ram 28 yields to allow the roller 30 to move. In a modification, Fig. 9 (not shown), the hold-down is constantly forced downwards by an hydraulic ram, but is restrained from moving by follower arm which is fixed to the top of the hold-down slide and curves around the crank-shaft so that the follower is pressed down on to the cam (32). When the hold-down contacts the work, the continued rotation of the cam causes the cam surface to move away from the follower.

Abstract: 1,206,968. Underwater acoustic telemetery. BENTHOS Inc. Oct.6, 1967 [Oct.10, 1966], No.45959/67. Heading G1N. Information represented by the level of a signal is telemetered through water by varying the spacing between pairs of acoustic pulses which may be transmitted as acoustic waves. As described information as to depth, pressure salinity or temperature of a trawl-net is transmitted to the trawler by pairs of 12 kilo-Hertz acoustic pulses transmitted once per second. These are generated as shown in Fig. 2, by adding in a circuit 52 1 p.p.s. pulses from generator 46 and pulses delayed in 36 by an amount representing the sensed information. These then modulate the output of a 12 kilo-Hertz oscillator. A standard echo sounder in the trawler receives the pulses and if the pen recorder of the receiver is approximately synchronized with the transmitted pulses two traces are produced which are spaced by an amount representing the gap between the pulse pairs; Additional information may be transmitted by additional pulses which may be of different frequency and the display may alternatively be of digital form representing digital transmitted signals.
