Title: Single lever engine throttle and clutch control
IPC: F02D29/00
Filed: 1961-08-25
Abstract: 932,181. Controlling engine and clutch. MORSE INSTRUMENT CO. Aug. 25, 1961 [Sept. 2, 1960], No. 30686/61. Class 7(6). A single lever engine control unit, comprises a throttle control mechanism including a wheel drive member 20, Fig. 1 rotatable by a lever 15, a clutch control mechanism including a shuttle block 54 which moves tangentially of the wheel drive member to engage the clutch, wherein a first driving connection between the shuttle block and the wheel drive member engages the clutch during the first portion of rotation from a neutral position of the wheel drive member and a second driving connection disengages the clutch on return of the wheel drive member. A 45 degrees movement of lever 15 from the neutral position shown in Fig. 1, causes engagement of rollers 58, 59, Fig. 2 by the sides 31, Fig. 4 of indentations 29, 30 in the wheel drive member rims 24 and'25. Shuttle block 54 moves rectilinearly to the right and engages the engine clutch through cable 62 whilst at the same time only a slight displacement of push rod 36 is caused, which is absorbed by the backlash in cable 39 without causing opening of the throttle. Continued rotation of lever 15 beyond the forward engine-idling position shown in Fig. 4 opens the throttle whilst shuttle block 54 is maintained in its displaced position by the locking effect of bearing surfaces 26 and 27 and tracking surfaces 52, 53 against rollers 58, 59 respectively. As lever 15 is counter-rotated towards neutral position, pin 33 engage surface 82 of the cam recess 70, to return shuttle block 54 to the clutch disengaged position. The control unit operates similarly for engine reverse clutch engagement and the swivel connection 35 may be displaced by 180 degrees for pull operation of the throttle. Two similar housings may be mounted side-by-side for twin engine controls. Braking friction is provided by a wavy spring washer 22.

Filed: 1924-12-23
Abstract: 245,924. Turner, I. Dec. 23, 1924. Fixed - abutment type; valve-gear; valves, distributing and cut-off.-In a reversible rotary engine having outwardly - sliding vanes c, which may be actuated by a cam h as described in Specification 235,784, an exhaust port v is located towards each end of each working-chamber x. Each port v is controlled by a piston valve v<1> acting directly thereon and operated by fluid pressure which is directed to either set of valves, for forward or reverse running, by means of a distributor comprising a double poppet valve i actuated by a reversing lever j. Steam enters a central chamber k and one or other of the side chambers k<1> which communicate through pipes l with the respective pairs of exhaust port pistons v<1>. Relief valves k<2> are lifted from their seats by the poppet-valve spindles i<1> in order to release the pressure behind the pistons v<1> of the exhaust ports to be brought into operation. In changing over the lever j, all the pistons v<1> are momentarily under pressure to keep the exhaust ports closed, so that the engine is slowed down for reversal by the trapped steam. Rotary inlet valves g<1> are driven by skew gearing m on a shaft n driven by skew gears m<1> from the main shaft o. A hand-wheel p<1> effects axial travel of the shaft n to regulate or reverse the timing of the valves in relation to the rotor. The rotary valve g<1> is fitted with a liner g<2> which can be turned to regulate the cut-off by quick-pitch screws q<1>, Fig. 4, movable axially by a fork q<3>. In a modification, a mechanical reversing-gear is provided between the engine shaft and the inlet-valve actuating shaft, so that the latter rotates constantly in the same direction and retains the given setting irrespective of the direction of running of the engine.

Title: A process for isomerising í¸-dehydroandrosterone and compounds derived therefrom
IPC: C07J1/00
Filed: 1935-11-08
Abstract: D <5> : <6>-Androstene compounds are isomerized to D <4> : <5>-androstene compounds by combining them with hydrogen halide and then splitting off hydrogen halide from the product.  Compounds mentioned are D <5> - <6>-dehydroandrosterone, D <5> : <6>-androstene-diol-3 : 17, and 17-alkyl-androstene-diol-3 : 17, together with the esters of these compounds, such as the propionates, butyrates and valerates, and also the ethers such as the methyl or ethyl ethers.  The elimination of hydrogen halide is conducted under mild conditions such as by the use of alkali salts of organic acids. Alkali acetates are particularly suitable for this purpose.  In examples: (1) an ether solution of D <5> : <6>-transdehydroandrosterone is mixed at 0 DEG  C. with an alcoholic solution of hydrogen chloride.  The hydrochloride so formed is heated in an alcoholic solution of potassium acetate to give D <4> : <5>-transdehydroandrosterone; (2) the hydrobromide of D <5> : <6>-androstene - 3 : 17 - diol is formed in a similar manner to the hydrochloride in example (1) and then treated with an alcoholic solution of sodium acetate to give D <4> : <5>-androstene-3 : 17-diol.

Title: Improvements in heating fans
IPC: F24H3/04
Filed: 1919-12-10
Abstract: 159,361. Canton, A. A. Dec. 10, 1919. Fan apparatus. - A fan operated by an electric motor drives a current of air in a series of impulses over an electrically-heated element. The fan 3 is carried by the motor spindle and is supported in a casing 4 with an open face and with segmental slots 5 in the other face. The spindle also carries the shutter 10 which has slots 11 similar in size and position to the slots 5. A conical split sleeve 12 on the shutter is held by friction on a cone 13 on the motor spindle. The heating- element consists of resistance wire 6 mounted on rods 7 carried by a rectangular frame 8 which is slipped into the open end of the casing and protected by a guard 9. Separate leads supply the fan motor and the heating-resistance; the motor speed is varied by means of the switch 17 and the heating-current by the switch 15. When the slots 11 register with the slots 5, a large current of air passes, but when the slots do not register this current will be materially reduced. By moving the shutter 10 along the shaft and so varying the friction grip, the speed of the shutter relative to the fan may be altered.

Title: Apparatus for monitoring moving processes
IPC: B65H23/04
Filed: 1965-07-21
Abstract: 1,108,902. Television. JOHN F. Mc- CARTHY Inc. 21 July, 1965 [26 March, 1965], No. 30954/65. Heading H4F. In an apparatus for monitoring a high-speed web 10 bearing periodically repeated printed colour patterns with the aid of a closed-circuit television system comprising a camera 74 and a cathode-ray display 76, there is provided a light source 72 which is pulsed on briefly to expose the camera to a registration mark 14, Fig. 3 (not shown), which is printed between each pattern, the control of the light source being effected by a photo-electric detector 70 which responds to a further mark 28, Fig. 3 (not shown), printed just ahead of the registration mark. The registration mark is formed of orthogonal lines in each of the colours used in printing the patterns and permits an operator viewing the cathode-ray display to detect and correct for colour registration errors in the patterns. The pulse signal produced by photo-electric detector 70 in response to the further mark is applied via preamplifier 92 and a gating amplifier 94 to control a discharge circuit 96 for energizing light source 72, which is a zenon discharge tube, and also controls a gated amplifier 144 in the camera signal channel whereby the signal is blanked during the light pulse to prevent a bright flash on display 76. The camera has a storage characteristic so as to furnish a signal between exposures. Gated amplifier 94 is controlled by a signal produced by magnetically actuated proximity switch 138, 140 associated with a web roller and functions to prevent the pulsing of the light source by false signals produced by the photo-electric detector in response to the printed patterns. Camera lenses 106, 108 of different angle of view may be chosen to accommodate for fast and slow web speeds by actuation of switch 120 connected to motor 116 which drives a rack and pinion mechanism 110 supporting the lenses. The polarity of the signal applied to the cathode-ray display may be chosen by switch 132. A blue filter 103 is associated with the light source. Details of a camera mounting which permits transverse and tilting adjustment with respect to the web is described with reference to Figs. 1 and 2 (not shown). A construction for the mounting of photo-electric detector 79 and associated light sources is described with reference to Fig. 6 (not shown).
