Title: Improvements relating to grouped engines, each engine independently driving a common member
IPC: F02B75/22
Filed: 1932-01-13
Abstract: 392,282. Power plant ; driving-gear. BAUDOT, F., 4 bis, Rue Antoine Bourdelle, Paris. Jan. 13, 1932, No. 1062. Convention date, June 15, 1931. [Class 7 (ii).] A number of independent engines driving a common propeller shaft are carried by a pair of endplates 14 mounted on a through tube 15. The plates are cruciform, an engine being received in each gap. The engines carry lugs 17 which pass between lugs 18 on bars 19 bolted to the plates 14 ; all the lugs are perforated to receive fixing bolts 21 by removal of which the independent engines can be separated from the mounting. Driving gear.--The engines may be coupled to an internally toothed wheel 26 on the propeller hub by friction clutches carried one on each engine crank shaft 12 ; the male movable part of the clutch is shifted from control rods 29 through rods passing inside the central tube 15. At starting one engine only is clutched to the propeller shaft, the remaining engines being thereafter clutched to the one to be first started and thereby run up. In a modification each engine drives a pump 32, Fig. 3 ; all the pumps deliver to a single hydraulic motor 38, Fig. 4, of the gear-wheel type, one wheel being direct coupled to the propeller. A non-return valve 34 is placed on the delivery of each pump and a control valve 44 on its suction side ; by closing any one of these valves the corresponding engine is disconnected from the motor 38. The supply and exhaust ducts 37, 41 of the motor are concentrically arranged ; by means of a throwover valve the function of these ducts may be reversed and a braking effect obtained on the propeller.

Title: Improvements in electrically driven gyroscopes
IPC: G01C19/08
Filed: 1918-01-22
Abstract: 191,407. Low, A. M. Jan. 22, 1918. Torpedoes, locomotive. -An electrically-driven gyroscope which may be employed in connection with the steering of torpedoes, is provided with means whereby it may be deflected to one side or the other as desired. The rotor a is provided with an armature f consisting of a number of turns passing through apertures in the rotor and partially embraced by the pole-pieces h. The armature is normally rotated by the field due to the main winding i and there are also provided additional windings l, m which set up fields respectively in advance and in retard of the main field. By selectively exciting one or other of the auxiliary fields in addition to, or instead of, the main field, the speed of the rotor is increased or diminished in order to produce limited precession of the rotor axis c-c around the vertical axis d-d. The two auxiliary fields may be replaced by a single field which can be excited in one direction or the other.

Title: Improvements in and relating to the conversion of olefines into diolefines
IPC: C07C5/333
Filed: 1942-02-02
Abstract: Butylenes and pentenes are converted to diolefines by catalytic reaction in gaseous or vapour form in presence of a metallic hydrogenation-dehydrogenation catalyst at a space velocity of 0.3 to 1.0 litres of the starting material in its liquid state per litre active catalyst volume per hour under atmospheric pressure at 550-700 DEG  C.  If sub-atmospheric pressure is used or a non-reactive gas such as nitrogen, helium, steam, or methane is added, the minimum space velocity is 0.05 litre, the maximum space velocity still remaining at 1.0 litres as above for a partial pressure of the starting material of 100 mm. of mercury.  The catalyst may be copper which has been oxidized and subsequently reduced.  The first Provisional Specification refers to the conversion of trimethylethylene to isoprene and cyclopentene to cyclopentadiene. Specifications 307,945, [Class 2 (iii)], and 532,942 are referred to.

Title: Tape recording apparatus
Inventor: SCHUETZ ALFRED
IPC: G11B15/60
Filed: 1955-01-18
Abstract: 789,085. Magnetic recording and reproducing apparatus. STANDARD APPARATE FABRIK GES. Jan. 18, 1955, No. 1461/55. Addition to 787,902. Class 40 (2). In an apparatus as in the parent Specification the transverse movement of the magnetic head or heads is effected by drive means operated by a controllable sliding clutch. When a notch in the magnetic tape operates switch 19, a solenoid 20 draws a clutch pad 18 against the flange 12 of a reel shaped member 12-27, freely rotatable on a worm shaft 13 to which the clutch pad 18 is keyed. A rotating friction wheel 6, normally in contact with flange 12, thereby causes shaft 13 and shaft 16, controlling transverse movement of a head carrier-plate 17, to rotate. Switch 19 is almost immediately broken but circuit has in the meantime been also established by a parallel switch 22 operated by a cam 23 and circuit through solenoid 20 is maintained until both of the switches 22, 24 are broken at the same time, and this corresponds to 10 revolutions of shaft 13. When the heads 3 on carrier-plate 17 reaches the last sound track on the tape, a switch 25 energizes a solenoid 26 which moves friction wheel 6 against the flange 27 of the reel-shaped member 12-27 and reverses its direction of rotation. Solenoid 20 is also energized and the shafts 13 and 17 are therefore also driven in reverse direction. During this return movement circuit is maintained through solenoid 26 until switch 28 is operated by plate 17, at which moment wheel 6 is restored to driving engagement with flange 12, and switches 22, 24 become operative to stop the traverse of plate 17 when the magnetic heads 3 coincide with the first track on the tape. A manual control 29 is provided for the purpose of selecting an individual track on the tape. When control 29 is rotated in one direction solenoid 20 is energized to effect a forward drive of shaft 13 so that plate 17 is raised, but when rotated in the reverse direction wheel 6 is moved so that a reverse drive is obtained. By means of a cam 9 acting on a rod or wire 8 to control the axial position of wheel 6, the velocity of traverse of plate 17 is increased in accordance with the amount of rotation of control 29.
