Patent GB-452728-A (GB)
Title: Improvements in or relating to systems for steering craft, more particularly aircraft
IPC: G05D1/08
Filed: 1935-02-28
Abstract: 452,728. Electric control systems. SIEMENS APPARATE UND MASCHINEN GES., 4, Askanischer Platz, Berlin. Feb. 28, 1935, No. 6433. Convention date, March 2, 1934. [Class 40 (i)] In a system for steering craft, more particularly aircraft, employing automatic gear for both course and curve flying, change over from course travel to curved travel is prevented unless the curved travel controlling means is in its normal zero position. As shown the rudder 17 of an aircraft is operated by a motor 16 which may be controlled by either the automatic compass - controlled gear 10 or the curved travel steering gear 21. When under automatic control, deviation of the aircraft from a set course operates in known manner a resultant field relay 14 which causes operation of the rudder motor 16 in one or other direction until follow-up contacts 15a are operated to open the motor circuit. When it is desired to change over to curved travel a switch 22 is operated and provided contacts 7, 8, which are closed only when the curved travel control means 21 are in the normal zero position, are closed a relay A is operated to connect at the contacts a<1> ... a<4>, the resultant field relay 14 to the curved travel control apparatus. If, on desiring to revert to curved travel, the gear 21 is off-normal, the relay A remains inoperative upon operation of the switch 22 and curved travel is prevented. The control mechanism 21 comprises a cam driven through gearing by a handle 21d, and adapted to close progressively pairs of contacts 1<1> ... 61 or 1<11> ... 611 according to the direction of rotation. Each set of contacts is associated with a resistance which is connected to one of the windings of the resultant field relay 14. The amount of resistance included in one or other of the relay winding circuits depends upon the direction and degree of rotation of the cam and consequently the corresponding deflection of the relay contact determines the amount of rudder deviation.

Abstract: 863,104. Temperature-sensitive resistors. SIEMENS-SCHUCKERTWERKE A.G. Feb. 27, 1957 [Feb. 27, 1956], No. 6532/57. Class 37.  An electric circuit comprises a power thermistor consisting of a semi-conductor having a resistance-temperature characteristic which at first rises and then falls and having a large ratio between its electron and hole mobilities, the majority carriers having the lower mobility, and the semi-conductor operates on the rising part of its characteristic and also on the falling part. The semi-conductor may consist of P-type indium arsenide with zinc as impurity, or of any other A III B v  compound or of Mg 3 Sb 2 . The fact that the thermistor is operating over the changeover region of positive to negative temperature coefficient increases the response to temperature change. Specification 748,799 is referred to.
Patent GB-417031-A (GB)
Title: Improvements in or relating to a process for making hard rubber dust
IPC: C08J3/12
Filed: 1934-03-01
Abstract: A process of making hard rubber dust, for use for example as a compounding ingredient in the production of hard rubber articles, consists in heating an intimate mixture of rubber, water, and vulcanizing ingredients in amount sufficient to yield hard rubber under high pressure for a period of time sufficient to produce hard rubber and then suddenly releasing the pressure.  The mixture is either heated in the form of an aqueous dispersion comprising rubber and vulcanizing ingredients, or the dispersion is coagulated to a solid mass, or vulcanizing ingredients and water are milled into rubber.  The product is either in a form suitable for use directly in hard rubber manufacture, or is in a form in which it can be readily disintegrated to a fine hard dust.  In an example, 100 parts of rubber (solids) in the form of normal latex are mixed with 60 parts of sulphur in the form of an aqueous paste and the dispersion is thickened by known thickening agents.  The thickened dispersion is introduced into a high pressure bomb and heated.  The pressure is raised rapidly to 1000 lbs. per sq. in, and this pressure is maintained for 30 minutes.  The pressure is then suddenly released by a quick opening valve to explode the hard rubber mass, the contents of the bomb being then discharged into a suitable container.

A ship's hull designed to be completely and inherently stable, to eliminate rolling and pitching and not to require an anchor has an athwart section over at least the greater part of its length which comprises at its lower part two downwardly tapering projections N, S, Fig. 8, having their outer boundaries distant from the fore and aft central plane by approximately half the beam, and a central projection of much less depth than the two projections with a section varying from one position to another along the hull. On a central vertical fore-and-aft plane the hull is bounded at the top by a line D, Fig. 7, of slight curvature, downwardly concave throughout and at the bottom by a line C of slight curvature convex downward for most of its length but of reversed curvature at its after portion, the fore part being rounded and the tail part pointed. In plan, the hull is bounded by curved fore-and-aft lines G, G<SP>1</SP>, Fig. 9, generally convex outwards over the forward part and concave outwards over the after part, both fore and aft parts terminating in two lateral forward or aft projections N<SP>1</SP>, S<SP>1</SP> with a smaller central projection W between them. A short forward portion of the outline may also be concave outwards. Fig. 7 shows the various athwart sections. at the indicated parts of the hull. The lateral rearward fins or projections K, K<SP>1</SP> swivel on pivots 10, Fig. 16, for steering and controlling the vessel and may be moved in unison for steering or in contrary motion for braking and trimming. Eccentric studs on the fins 11, 33 are linked to a pivot pin 22 movable fore and aft on a longitudinal slide 24 to effect contrary motion, the slide being movable athwartship on a slide 23 for steering. Four ballast tanks, arranged two on each side of the central plane W, O, W<SP>1</SP>, Fig. 9, with one forward and one aft of the point O, are filled through gills by the forward motion of the ship against compressed air trapped in them. Twin propellers rotating at the point of minimum cross section of a casing having two loops convex downwards drive the vessel. An aerodynamically streamlined superstructure may be mounted on the hull which itself may be made of paramagnetic material. The mass of water flowing between the downward projections N, S, entrains air along the faces of the hull to reduce skin friction and acts as a stabilizer. It is also stated that these projections give stable support to the hull when grounded and the construction facilitates refloating.
