Title: Improvements in or relating to the operation and control of change speed gearing, particularly applicable to motor cars
IPC: F16H63/30
Filed: 1921-04-09
Abstract: 183,411. Ter Cock, C. April 9, 1921. Controlling variable-speed gearing.-Solenoid selector control mechanism such as that described in Specification 105,192 and suitable for motor-cars is modified to change from any speed directly to reverse. Means such as a switch 12, Fig. 1, connecting wires 11, 13 are provided to open the circuit of the selector-operating solenoid 21 until the reverse position is reached, when the circuit automatically closes. The control handle 7, Fig. 1, described in Specification 173,802, is turned to select the new gear, and when in neutral position is slid longitudinally to effect the reverse. The selective controller 8 is geared to the handle 7 and turned thereby. The second solenoid 18 is for unlocking the selector. The switch 12 is that shown in Figs. 3 and 4 at 39, 40. As shown in Fig. 3, the knob 43 of a spring bolt 42 has been pressed to the left sufficiently to withdraw a locking-pin 44 from engaging a hole in a flange 7a of the handle 7 so as to allow the handle to be turned to change the gear. If it is desired to go directly to reverse, the knob 43 is thrust farther to the left into the position shown in Fig. 4. A lever 45 has been struck by a collar on the bolt 42 and turned so as to thrust the switch-carrying rod 41 to the right, breaking the circuit. The end 41a of the rod 41 then comes into the path of a pin 46 on the flange 7<a> so as to stop the handle 7 in reversing position whichever way the handle has been turned. The sliding movement to the left of the handle 7 to effect reversal causes the flanges 7<a> to engage and carry with it a collar 41b on the rod 41. The switch is again closed, and the solenoid acts. The lever 45 turns so that the bolt 42 is released from a catch 47 and springs to the right until its locking-pin 44 engages a hole in the flange 7<a> locking the handle 7.

Title: Cycloidal propellers
IPC: B63H1/10
Filed: 1971-05-28
Abstract: 1348661 Cycloidal propeller assemblies SIEMENS AG 28 May 1971 [18 June 1970] 18110/71 Heading B7G A cycloidal propeller assembly comprises: a cycloidal propeller having blades 2-5 variable in pitch and adjusting means for varying the pitch of the propellers; first and second signal paths for conveying signals x 0 , y 0  in dependence upon which said adjusting means varies blade pitch; and function generating means 19 for causing the signal x 0  conveyed by one of said paths to be modified as a function of the other y 0 . With the propeller mounted in a ship, a steering wheel 20 is rotated to provide the signal y 0  from a transmitter 21 to an output 21a, the signal controlling a servomotor 13 which receives the signal unaltered y to move the control centre S of the propeller a distance R y . A throttle control 14 has a transmitter 15 providing a signal x 0 . The function generating means comprises a function generator 19 providing a signal #1-y<SP>2</SP> 0  to a multiplier 18 which multiplies this function with the signal x 0  to provide the modified signal x = x 0 #1-y<SP>2</SP> 0  which is fed to the servomotor 12. The signal causes the servomotor 12 to move the control centre S a distance Rx to affect the ship's speed, the servomotor 12 causing movement of the control centre along the ship's fore/aft axis, the servomotor 13 causing motion transverse thereto. The effect of the function generating means is to cause the thrust of the propeller and hence the ship's speed to decrease with increasing helm angle. In another embodiment, Fig. 3 (not shown), the motion of the control centre S caused by the respective servomotors is still mutually at right angles, but the motors are offset with respect to the ship's fore/aft and transverse axes, the offsetting being compensated by computer amplifiers which respectively modify the signals x and y. It is stated that additional circuits for controlling the servomotors may provide: (i) Output power limitation. (ii) Optimizing of the speed of the engine and the blade setting of the propeller. (iii) Initiation emergency procedures in the event of oil failure or intense oil heating. (iv) Direct command of operation of a tugmounted engine from a sea-going ship being manoeuvred by the tug. (v) Optimizing of acceleration and decelerating manoeuvres. (vi). A system to keep a working platform (e.g. a drilling ship or crane) in a fixed position.

Title: Preparation of mineral oil solutions of polymeric materials
Inventor: HAWKINS ELEANOR RUTH
IPC: C10M145/02
Filed: 1951-08-01
Abstract: A mineral oil solution of polymerized olefinic materials is prepared by subjecting the polymer to shear in the presence of sufficient mineral oil to produce a concentrate that is a homogeneous fluid, but with less mineral oil than is required for the final solution, the concentrate being subsequently blended with the remainder of the mineral oil to the required dilution. The final solution may be added to mineral oils as a thickener or viscosity index improver. Preferred polymers are polybutenes, polyethylene, linear copolymers of olefins and diolefins such as butyl rubber, polymers of acrylic and alkyl acrylic acids, and polymers and copolymers of one or more unsaturated esters such as vinyl acetate and decyl maleate.  The polymer may be one which has been partially degraded, for example by subjection to shear, before introduction of the mineral oil.  In an example, butyl rubber is milled at 160-190 DEG  C. for 90 minutes in the presence of 0.5 per cent mercaptobenzthiazole in a rubber mill. The degraded polymer product is then dissolved by introducing mineral oil into the mill and operating the mill until a homogeneous fluid is obtained.  The solution is then discharged into a blending vessel in which it is blended with further mineral oil.  Specification 716,706 is referred to.ALSO:A mineral oil solution of polymerized olefinic materials is prepared by subjecting the polymer to shear in the presence of sufficient mineral oil to produce a concentrate that is a homogeneous fluid, but with less mineral oil than is required for the final solution, the concentrate being subsequently blended with the remainder of the mineral oil to the required dilution.
