Title: Steering means for ships
Inventor: ENGELBRECHT HELMUT
IPC: B63H20/12
Filed: 1962-06-29
Abstract: 975,436. Differential gear. INSTITUT FUR SCHIFFBAU. June 29, 1962, No. 25069/62. Heading F2D. [Also in Division B7] In a ship's propulsion unit (see Division B7) having its propeller shaft 21 driven by two oppositely rotating concentric vertical shafts 12, 14 obtaining their drive from a horizontal driving shaft 2 through a bevel gearing, the driving bevel gears 13, 15 on the vertical shafts engage in bevel gears 6, 4 arranged on the driving shaft and adjustable angularly relatively to one another to cause swivelling of the propeller about a vertical axis. The bevel gear 4 on the end 3 of the shaft and the bevel gear 6 on the flange 5 thereof have external and internal teeth 7 and 8 respectively in mesh with intermediate gears 9 on axle pins 10 in the flange 5. The axle-pin 10 of one of the gears 9 has a worm gear 22 which meshes with a worm 23 carrying a bevel gear 26 in mesh with a bevel gear 27 surrounding the shaft 2 like a sleeve and with a bevel gear 28 mounted thereon. The bevel gears 27, 28 have spur gears 29 and 30 respectively with the same number of teeth, and these mesh with two pairs of gear wheels, each pair consisting of a gear 31 and a gear 32 having one more tooth and accommodating a magnetic winding 33. The housing 1 carries magnetic windings 35, 36 opposite gears 31. Normally the gear 9 is held by the worm and worm gear so that the bevel gears 4, 6 rotate with the shaft 2. If the bevel gear 28 is held stationary by its meshing gear 31 due to energising the winding 35, the gear 26 will roll on gear 28, thereby rotating the worm 23 and gear 22 and bevel gear 9, this latter causing angular movement of the gears 4 and 6 relative to each other, thus producing swivelling of the propeller. The swivelling will be in the opposite direction if the gear 27 is stopped instead of the gear 28, this being done by energising the winding 36. This swivelling action is rapid. A slower one is obtained by energising a winding 33 to lock two wheels 31, 32 together. Since one wheel has one tooth more than the other, a slow relative rotation of the bevel gears 27 and 28 relatively to one another (and hence a slow swivelling of the propeller) takes place.

Title: Improvements in or relating to electrical apparatus for measuring changes in pressure or displacement
IPC: H04R23/00
Filed: 1944-12-18
Abstract: 592,362. Shook detectors; gramophone pick-ups. DODDS, E. M. Dec. 18, 1944, No. 25367. [Class 40 (iv)] [Also in Groups XXXVI and XL] Change in pressure or displacement is measured by subjecting the insulating material of an insulated conductor to variations of compression and connecting the conductor through an amplifying unit to a sensitive device for measuring electrical effects. Fig. 1 shows an arrangement for detecting detonation or knock in internal combustion engines. A loop of insulated wire 1, such as a single rubber covered cable of an ordinary 5 ampere flexible cable, is placed between the two top fins on the cylinder barrel of an air-cooled engine cylinder 2, the ends of the loops being twisted together with or without stripping of the insulation to give an open or closed loop. A lead 3 is taken from one end of the wire to the grid 4 of an amplifying valve 5, the plate 7 of which is connected through a blocking condenser 8 to the plate Y1 of a cathode ray oscillograph 9. When detonation or knocking, or incipient knock, occurs in the cylinder an E.M.F. is stated to be generated in the wire by mechanical shock. A modification is shown in Fig. 3, in which the loop 1 is directly connected to the primary coil 3 of an audio-frequency transformer 2 to control a neon tuning indicator 15 which indicates the intensity of the knock. Fig. 5 shows the application to a gramophone pick-up in which a needle 1 enters the sound groove 2 in a record 3. Two pairs of insulated conductors 5, 6, 7, 8 are arranged as shown and connected to leads 9, 10 leading to an amplifier. Motion of the needle 1 to the right compresses the conductors 5, 7 and each generates a small E.M.F. Similarly, motion to the left compresses the conductors 6, 8. In a modification the conductors 5, 6 are omitted, the upper end of the needle being located in a conical depression in a pad of rubber in the top of the casing 4. Other types of insulated conductor may be substituted for rubber insulated conductors, for example asbestos insulation may be employed in high temperature conditions.

Title: Electronic counting circuit
Inventor: DUUREN HENDRIK CORNELIUS ANTHO
IPC: H03K21/00
Filed: 1954-09-06
Abstract: 794,190. Electronic counting apparatus. STAATSBEDRIJF DER POSTERIJEN, TELEGRAFIE EN TELEFONIE. Sept. 6, 1954 [Sept. 10, 1953], No. 25845/54. Class 106 (1). [Also in Group XL (c)] A counting circuit comprises n tubes arranged so that, in each state of the circuit, p tubes are conducting. The circuit thus has a maximum number of state's equal to the number of combinations of p out of n, but not all of these states need be utilized. For a decimal counter, five triodes 1-5 are arranged to conduct two at a time in an arbitrarily chosen sequence. The anodes and grids of these triodes are connected respectively to leads A1-A5 and G1-G5 between which are connected locking circuits, one of which is provided for each of the ten possible states. Each locking circuit comprises a gate formed by two biased rectifiers, e.g. 08, 09, connected to the anode leads of the two triodes which are conducting in the corresponding state, the output of the gate being connected to three biased rectifiers, e.g. 03-05, connected to the grid leads of the triodes which are non-conducting in the corresponding state. The arrangement is such that the low anode potentials of the two conducting triodes cause the grids of the non-conducting triodes to be held at a low potential. Input pulses to be counted are applied through a triode 0 to ten switching circuits, each formed by three biased rectifiers, e.g. 00, 01, 02, connected to the anode AO and to two of a set of anode leads VA1-VA5 respectively. The leads VA1-VA5 are connected to the anodes of the triodes 1-5 through delay circuits, e.g. R1, C1. On receipt of a negative input pulse, that switching circuit connected to the two triodes at present conducting produces a negative pulse at its output WO which is connected over a rectifier, e.g. 16, to that locking circuit corresponding to the next state. This pulse lowers the grid potentials of the three triodes which are to be non-conducting in that state, which the circuit is thus caused to assume. The input circuit is so adjusted that the duration of the switching pulse is less than the delay produced by the delay circuits R1, C1, &c. By reversing the polarities of the rectifiers and their biasing voltages, a complementary circuit is obtained in which three tubes are conducting in. each state. A neon indicator tube may be associated with each triode. The circuit may be used as a storage device,.in which case the switching circuits may be omitted.
