Cam-actuated revolving-cylinder pumps.-A pump for the lubricating system of an internal-combustion engine has a stepped plunger n reciprocated within a stepped bore in a ported sleeve k rotated in a casing integral with the crank case b by the engine shaft through worm gear l, m. A pin o projecting from the intermediate portion n<3> of the plunger is secured thereto by a screw o<1>, Fig. 5, engaging a groove on the pin and projects through a longitudinal slot p in the sleeve k. The head o<2> of the pin travels in a a track ring q fixed by bolts s at an angle to the sleeve, thereby causing the plunger to reciprocate as the sleeve rotates. The ring q is formed from a flat metal blank by ben'ding up the sides. The casing is divided into two chambers a, a' by a partition d and is provided with a cover plate having a machined surface engaging the partition d. The smaller end n<1> of the plunger draws oil from a tank through a pipe u and delivers it through a passage v to the engine bearings and cylinder walls. The chamber a' communicates with the engine sump through an opening l provided with a filter, and the larger end n<2> of the plunger draws oil from this chamber through a radial opening f in the outer closed end of a hollow bush f which is rotatable in an aperture g, and delivers it through a passage w, a groove x in the face of the partition d, and a pipe y to the tank. The level of oil in the sump is adjusted by rotating the bush f, which is retained in adjusted position by a pin j engaging notches h. Oil leakage into the chamber a passes to the sump through a drain aperture. Specification 249,629 is referred to.

Title: Can opener
IPC: B67B/
Filed: 1973-05-29
Abstract: 1426232 Can openers WESTINGHOUSE ELECTRIC CORP 29 May 1973 [1 June 1972] 25469/73 Heading B8D In an electric motor-driven can opener of the type comprising a frusto-conical cutting wheel 64 for severing the outer layer of double seamed can end rim and drive wheel 40, which is axiallydisplaceable with a motor-driven shaft 42 into operational can rim-cutting relationship adjacent the cutting wheel and which has an inner knurled cylindrical section 98 engageable with a can rim top and intermediate knurled conical section 100 for engaging the inner side of the rim, the spacing "Y" between the cutting edge of the cutting wheel and the drive wheel inner section is in the range of from 0À046 to 0À058 inch. The drive wheel pressure angle 104 (i.e. the angle of inclination of the face of the conical section to a plane normal to the drive wheel axis) is 15 ¢ degrees. The cutting wheel has a dive angle (i.e. the angle between the plane of the cutting edge and the plane of the can rim top) of 15 to 16 degrees, and the spacing "G" the cutting edge and the conical section, when the wheels are in their operational relationship with the can rim interposed therebetween, is in the range of from 0À013 to 0À020 inch. The.drive wheel shaft is journalled in a die cast block 38, which is mounted in a plastics housing 10, 12 and 14, extends through a fixed cam block 44, an operating handle 48 and cam 46, and fixedly carries a gear-wheel 52, which is coupled through gearing to an electric motor 72. When the operating handle is rotated, Figs. 3 and 12 (not shown), motor-energizing slide switch 84 is closed and pins 46a on the cam ride up recesses 45 in the cam block to urge the cam and hence the shaft to the right to bring the drive wheel adjacent the cutting wheel with a can rim gripped therebetween. The force with which the can rim is gripped is governed by compression of a set of force-transmitting conical spring washers 50 located between the can and gear-wheel 46. This compression is itself a function of the initial spacing "G" and the thickness of the can rim and ensures that the cutting force is automatically varied to increase with increased thickness of can rims so that proper severance of the can rim outer layer occurs without excessive penetration thereof regardless of can size. The cutting wheel edge is blunted and provided with circumferentiallyspaced notches, Figs. 9-11 (not shown). Adjustment of both the spacing "Y" and the spacing "G" is facilitated by the screw 66 and nut 54 respectively.

Abstract: 1,149,367. Vertical take-off aircraft. NORDAVIATION SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES. 8 June, 1966 [10 June, 1965], No. 25630/66. Headings B7G and B7W. A vertical take-off aircraft comprises two tiltable propulsion units, the thrust and inclination of which, are controllable by an autopilot or by operation of pilot controls A, B, C, D acting through a number of interconnected ordermixing units PI . . . PIV to operate the elevator and to more servo assisted output members 11- 14 connected to units a 1 , a 2  adapted to transfer the movements into corresponding thrust and inclination alterations. The pilot controls are of conventional form and comprise a joy-stick A, a rudder-bar B, a general thrust or fan blade pitch control C and a trim control D for varying the inclination of the propulsion units. Operation of the joy stick A or rudder bar B may effect a general or differential variation of the thrust or inclination of the propulsion unit, depending on the phase of flight. The joy-stick A simultaneously controls the elevator via a coupling 8. When a control is operated it results in appropriate output movement of the members 11-14 as determined by the settings of the order-mixing units under the influence of the positions of the other controls. The order-mixing units are designed to transmit control movements to the members 11-14 in accordance with the phase of flight of the aircraft whereby corrections for yaw, pitch and roll may be effected by the same set of controls irrespective of the phase of flight. The manner in which the pilot controls A, B, C, D, the order-mixing units and the transfer units are connected is shown diagrammatically in Fig.3 In the embodiment described the order-mixing units PI . . . PIV are mechanical devices. Figs. 4, 5, 6, 7 (not shown), but it is stated that they may be electro mechanical, pneumatic or hydraulic. Fig. 8 shows the arrangement whereby the output movements of the members 11-14 are assisted by servomotor systems V, V<SP>1</SP>. Each servomotor system V or V<SP>1</SP> controls a pair of the output members 11, 12 or 13, 14 and since they are substantially identical only the servomotor system V will be described. The servomotor system V comprises a pair of bell-cranks V a , Vd interconnecting the portions of the members 12, 11 respectively. Inserted in the member portions 12, 11 coming from the order-mixing units are dynamometers Vi 2  and Vi 1  comprising a stack of carbon discs li. The dynamometers are connected electrically to magnetic powder clutches 6g 2 , 6g 1 , the input members 5g 2 , 5g 1  being driven by an electric motor Vh. If the dynamometers are tensioned or compressed by movement of the members 11, 12 connected to the mixing units, the resulting change in resistance of the carbon disc li causes appropriate energization of the respective clutch to cause rotation through gears Vf, Vc of the bellcranks and consequential movement of the portions of the members 11, 12 leading to the transfer units a 1 , a 2 .
