Title: Improvements in packing holders for fragile articles
IPC: B65D85/32
Filed: 1930-07-30
Abstract: 361,948. Packing fragile articles. KOPPELMAN, M., 1050, Park Place, Brooklyn, New York, U.S.A. July 30, 1930, No. 22994. [Classes 18 and 94 (i).] A receiver for fragile articles and adapted to be positioned in a wrapper, carton, &c. comprises a substantially flat sheet of moulded or felted fibrous material divided by folding lines into approximately rectangular areas, and the material, when folded along the fold lines creates cells or compartments, each containing mound-like raised or bulged formations which separate the articles and also cushion them, some of the rectangular portions when folded constituting upstanding side walls of the cells or compartments. Vegetable fibre or pulp is moulded preferably as described in Specification 196,259, [Class 18, Boxes &c.], to produce a sheet 10, Fig. 2, having parallel fold lines 11 .. 15 which divide it into portions 16 .. 19 having hollow raised parts or projections 20 .. 23 and portions 29, 30, Fig. 1, having in staggered relationship to the projections bowl-like depressions 33 with raised centres 34 terminating in flat tops 35. The sheet is folded about the lines 11 .. 15 so that the portions 29, 30 become bases and the portions 16 .. 19 vertical dividing walls for compartments which are completed by the meeting of the projections 20, 21 and 22, 23. The erected sheet may then be disposed in an outer carton 13 or be merely wrapped. The projections 20 .. 23 provide air-pockets which assist to cushion the contents of the package. In modifications, the projections 21, 22 extend completely across the base portions 29, 30 and either the portions 16, 19 are omitted or the portions 16, 18 are replaced by plain portions. In other forms, the upstanding portions comprise small and large ribs 55, 56, Fig. 7, and the base portions are formed with large or small corrugations 52. Specification 213,465, [Class 18, Boxes &c.], is referred to.

Abstract: 1,192,792. Assembling dynamo-electric machines. RANCO MOTORS Ltd. 15 May, 1968 [18 May, 1967], No. 23258/67. Heading B3A. In a method of assembling an electric motor comprising a mounting block 1, a rotor 5 mounted to rotate relative to the mounting block and a stator 6 secured to the block 1, a purely axial compressive force is applied to the stator as it is secured to the block. When the rotor is mounted on a shaft 4 an assembly can 10 is held thereover to determine the necessary air gap. The stator is aligned on the can 10 and bolts 8 are started in their threads, but not tightened. The axial compressive force is applied by four clamps 11 which are connected to air rams 12. When the pressure is applied bolt runners are activated to screw home the bolts to a predetermined torque value.

The piston 10, 11, on moving in direction 26 to disengage the clutch disengages it through a further piston 23 between which and piston 10, 11 is an enclosed volume 33 of fluid through which the movement is transmitted. On there being wear in the clutch the clutch spring 42 still exerts a force in direction 35 on release of pedal 7, and return of piston 10, 11 under the action of spring 22, and this force opens a valve arrangement 27 by pressing it against a seat 21 to allow fluid to escape from chamber 33 and allow piston 23 to move to compensate for the wear. A spring 34 ensures that there is no free play in the device.

Abstract: 482,370. Valve generating circuits. WHITE, E. L. C., and BLUMLEIN, A. D. Aug. 27, 1936, No. 23489. [Class 40 (v)] A valve 7 supplies saw-tooth current to a winding 8, which is coupled to an inductive load 11, such as the deflecting coil of a cathode-ray tube, a diode 12, or the equivalent, is connected across a portion of the winding or of a coupled winding, and the ratio of turns in the winding is such that the average current in the diode is equal to, or greater than, the average current in the valve. The current from the diode stores energy in a condenser 14, which assists the flow of anode current in the valve. The input of the valve is coupled to a generator 1 of saw-tooth waves, and the winding forms the primary of a transformer 9, the secondary 10 of which is in circuit with the deflecting coil. An adjustable resistance 16 in the common supply to the anode of the blocking oscillator 1 and to the screening grid of the pentode 7 varies simultaneously the amplitude of the voltage fed to the controlling grid and the voltage supplied to the screening grid. This maintains the shape of the output wave similar for all amplitudes.

[Class 120 (ii)] In spinning-machines for flax, jute and like materials provided with multiple lifter rails, a sliding-rod 6 with a catch 7a normally engaging a wheel 8 in the operating-gear of the doffing-mechanism is arranged to be raised to release the catch, (1) by direct engagement of a stop 4a on the lifter rail with a collar 5 when the lifter rail is at the top of its lift, and (2) by engagement of the stop with a collar 5a through a lever when the lifter rail is lowered after the completion of the set, whereby, in the former case, the doffing-mechanism can be operated to move the duplicate rail charged with the empty bobbins only when there is free passage below the working rail, and, in the latter case, when the working rail is properly lowered from its operative position. The mechanism is applicable to doffing-mechanism employing rotating discs for manipulating the lifter rails as described in Specification 385,621.

Title: Governor for turbo-supercharged prime movers
IPC: F02D1/12
Filed: 1960-07-06
Abstract: 899,670. Regulating. WOODWARD GOVERNOR CO. July 6, 1960 [Sept. 21, 1959], No. 23697/60. Class 7(6). [Also in Group XXIX] A fuel burning prime mover 10, such as that of a diesel-electric locomotive, has an exhaust driven supercharger 14, Fig. 1, a governor 17 to maintain the prime mover at a selected speed by regulating the fuel pump 12, means 70, 74 for measuring the pressure of the air delivered by the supercharger and mechanism actuated by the means to change the relationship between prime mover torque and speed whereby the fuel flow is matched to the air available. In the preferred embodiment, a centrifugal governor 39 having a manuallyadjustable spring-load 38 operates a pilot valve 33 controlling a servo piston 21 connected to the fuel pump. The connection between the valve and the piston includes a buffer piston 42 in parallel with a restriction 43 which causes a pressure opposing the valve movement to be applied to a flange 44 on the valve 33. Adjustment of the fuel pump or of the manual setting of the governor moves a lever 54, and through a link 57 and a lever 58, a valve 53 connected to the same supply conduit 34 as the valve 33 to adjust a vane type servomotor 48 connected to a rheostat in the field circuit of a generator 11. The engine load is thus decreased whenever the fuel supply is increased or the governor is set to a lower speed. The valve 61 is also caused to reduce the load when the pressure of the air delivered by the supercharger decreases. A conduit 71 from the outlet of the supercharger is connected to a bellows 70 co-operating with an evacuated reference bellows 74 to adjust a lever 75 engaging a bleed-off valve 80 in a cylinder 78 supplied through a restriction 79 from the conduit 34. A piston loaded by a spring and by a fluid load from the conduit 34 acting on a narrow upwardly facing annular surface adjusts the valve 53 in accordance with the setting of the bleed-off valve 80. To prevent fluid draining from the cylinder 78 when the engine is stationary, a non-return valve 88 is provided. U.S.A. Specification 2,478,753 is referred to.
