Title: Improvements in position and altitude finders
Filed: 1931-04-20
Abstract: 368,124. Departure rules &c. LEWIS, E. H., 327, Rielle Avenue, Verdun, Quebec, Canada. April 20, 1931, No. 11659. [Class 97 (ii).] A position and altitude finder comprises a fixed scale and sight, a transverse scale slidable towards and away from the fixed sight, and a movable sight mounted on the transverse scale and adapted to be brought into line with a sighted object. In the form shown, baseboard 15 is horizontally supported on a tripod with three spaced parallel grooves 17, 18, 19 in the board 15 pointing along the ship's course when the instrument is used at sea. A bar 22 which is maintained at right-angles to the groove 17 is provided with runners 24 sliding in the grooves 17, 18, 19. When in its extreme foremost position the bar 22 lies against a stop 20 and its rear edge coincides with the zero of a scale along the groove 17. A sight pin 26 is fixed at the other end of the groove 17 and sight pins 30, 31 are mounted on blocks 28, 29 slidable along a groove in the bar 22. The bar 22 and sliding blocks 28, 29 may be movable by shafts and pinions operated by thumb screws. The distance between the sight 26 and zero mark i of the groove 17 is divided into a percentage scale and a fractional scale. The bar 22 has evenly spaced scales e, f on its back edge and on its top face a scale indicating the percentage by which the distance from the sight 26 to the graduation exceeds the distance between the sight 26 and the zero point i. A vertical graduated post carrying two adjustable sight pins may slide in the groove 17 or may be fixed to the bar 22 and is used for determining altitudes. A scale of angles around the pin 26 may be marked on the board 15. Two observations of a distant object taken with a known displacement of the instrument between the observations enable the distance of the ship from the object and the distances from the object and ship of the foot of the normal from the object on to the ship's course to be determined.

Title: Improvements in or relating to liquid circulating systems
IPC: F16N7/40
Filed: 1944-06-19
Abstract: 580,604. Pumping systems. AUTOMOTIVE PRODUCTS CO., Ltd., and HENRY, H. P. June 19, 1944, No. 11665. [Classes 102 (i) and 102 (ii)] In a pumping system, e.g., for lubricating oil or remote hydraulic control, a pressure is maintained in the suction reservoir by a device, e.g., an air injector or air blower, actuated by the return flow of liquid. As shown, a pump 12 draws liquid from a closed reservoir 10 and delivers to a motor 18, exhaust from which returns through a pipe 19 and injector nozzle 23 to the reservoir. Flow through the nozzle draws air through a valve 28 and supplies it to the reservoir. Excess pressure in the pipe 19 opens a valve 33 and bye-passÞs some of the liquid direct to the reservoir. An air pressure relief valve 31 is provided.
Patent GB-1132274-A (GB)
Title: Improvements in or relating to transmission systems for the transmission of pulses
IPC: H04L27/02
Filed: 1966-03-17
Abstract: 1,132,274. Data transmission systems. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 17 March, 1966 [20 March, 1965], No. 11697/66. Heading H4P. In a single sideband digital data transmission system the transmitter comprises a network having a transmission characteristic equivalent to that of a subtraction circuit to which a signal is fed both direct and via a delay. In a transmitter, Fig. 1 (not shown), binary pulses are converted to differential form (3, 4) and pass to the network (5) referred to above, the delay in this instance being one bit. After filtering (6), the resultant 3-level signals are amplitude modulated (7) in a suppressed carrier modulator, and one of the sidebands is passed to the transmission line. A pilot carrier is added to the signal from the modulator. At the receiver, Fig. 3 (not shown), the pilot is used in the demodulation (14), the 3-level signal being full-wave rectified (20) to recover binary data identical to that at the transmitter input. D.C. level variations are countered by subtracting (21) from the binary signal a D.C. signal, derived from the demodulator by filtering (22), and passing the difference signal through a threshold circuit (24). The resulting signal is sampled (25) for regeneration of the binary data. Level control of the received signals may be achieved by selecting from the demodulator output a component at twice the carrier frequency which is then rectified and used to control an attenuator preceding the modulator. In a modification, Fig. 8 (not shown), the demodulated three-level signal is sampled at bit rate, the samples passing to positive and negative threshold circuits (50, 51) which feed a bi-stable circuit (52). The signal from this circuit, which is in differential form, passes to a modulo 2 adder (55) both direct and via a 1-bit delay (54), the adder output being the required binary data. In a further embodiment, Figs. 10 and 11 (neither shown), generally similar to that described with reference to Figs. 1 and 3, a square wave at half bit-rate is added to the output of the subtractor (58), and at the receiver this signal is extracted by a filter (73), full wave rectified (75) and passed to a tuned filter (75) which develops a sine wave at bit frequency. This is clipped (76) and differentiated (77) to provide bit-rate sampling pulses.

Abstract: 1390204 De-burring chain links MEYER ROTH & PASTOR MASCHINENFABRIK GmbH 13 March 1972 [11 March 1971] 11698/72 Heading B3L A method of deburring chain links having a circular link leg cross-section comprises using a device having a burring cutter displaceable in the direction of the link leg axis, said cutter having a cutting edge extending 180‹ in the circumferential direction of the chain link, and also having an actuating device whereby the burring cutter is pivotable about the link axis from an outside position situated symmetrically with respect to the link central plane through 90 degrees in both circumferential directions, wherein the actuating device advances the burring cutter from an initial position situated outside the link region first of all to short of the ridge, then pivots it through 90 degrees in one direction about the link axis, then pushes it forward again over the ridge in the direction of the link by axis for the first partial deburring operation, and moves it back, pivots it in the other direction through 180 degrees, advances it again over the ridge for the second partial deburring operation, then pivots it back in the first pivoting direction into the outside position, and finally returns it into the initial position. The cutter may be designed to cut in both directions of movement so that the return stroke prior to the second partial deburring operation is negated. Fig. 6 shows the cutting edge divided into two mutually symmetrical half-edges each forming a quarter of a circle, which is a convenient of making a cutting edge with the required obliquity.

Abstract: 586,876. Percussion shock-absorbers. AIR SUPPLY PACKS PROPRIETARY, Ltd. June 21, 1944, No. 11833. Convention date, June 21, 1943. [Class 108 (iii)] [Also in Group XXXIII] A shock-absorbing nose for attachment to an article to be dropped from an aircraft, consists of a percussion member containing at least one air-compression compartment and having such physical properties that when it is subjected to impact stresses it will initially crumple, at the same time compressing the air therein, and will finally be burst by the internal air pressure. Suitable materials for the nose are stated to be chipboard, moulded fibre or multi-ply paper. As shown, applied to a container for dropping supplies (see Group XXXIII), the nose comprises an outer tube 11<1> which engages a spigot on the container, and a conical nose-piece 11<2> formed of multiply paper. A diaphragm disc 11<3> divides the space below a further disc 11<5> into two sealed air compartments, and a sealing disc 30 rests on a spacing ring 11<7> and forms an abutment for the lower tube 15 of the container. A shock-absorbing pad 31 of sawdust, sponge or crepe rubber is located between the disc 30 and a further disc 15<2> which protects the contents of the container. The nose may have a weakened annular zone to ensure deformation before bursting, and for dropping on hard ground a modified construction may be used in which the plies are not adhesively secured together over an intermediate annular zone, see Fig. 17 (not shown), or the intermediate zone is stepped, see Fig. 18 (not shown). The provision of sealed air compartment is not essential, and small openings may be provided at or near the tip which become sealed on impact. The nose may be cylindrical, hemispherical or pyramidal in shape.

Abstract: 833,531. Calculating-apparatus. LEVI, R. April 16, 1957 [April 16, 1956], No. 12427/57. Class 106 (1). Apparatus for determining the optimum distribution of similar articles from a number of production centres to a number of consumption centres so as to minimize the transport costs comprises a set of balances Ha, Hb, one for each production centre, and a set of balances Hc, Hd, one for each consumption centre. The balances Ha, Hb are loaded .by unit weights P and adjustable weights P 1  so as to apply downward forces to bars J corresponding to the productions of the various centres. The balances Hc, Hd are similarly loaded to apply upward forces to bars K corresponding to the consumptions of the various consumption centres. The bars K are arranged beneath the bars J and at right angles thereto and each has, for each bar J, an adjustable rod t which is set so that the distance between its top end and the associated bar J, when the latter engages a stop bar E, represents the unit cost of transport between the corresponding production and consumption centres. The whole system then reaches a state of equilibrium from which the required distribution can be ascertained. Thus, the articles from a given production centre are directed to those consumption centres associated with the bars K having rods t contacting the corresponding bar J. Such points of contact may be indicated electrically. If any bars J remain in contact with the stop bar E, such centres are over-producing. Each balance comprises a parallelogram linkage supported at two fulcra, e.g. Fa, Fb arranged one above the other. Two such complete systems may be interconnected in cases where the manufacture of each article takes place in two different factories.
