Title: Improvements in or relating to a fluid pump
IPC: F04C2/10
Filed: 1950-01-25
Abstract: 669,704. Rotary pumps. ROLLINSON, E. W. (Sundstrand Machine Tool Co.). Jan. 25, 1950. No. 1954/50. Class 110(ii). A fuel pumping system has a rapid shut-off valve 17 for the delivery 19, which is opened at a pre-determined pump delivery pressure, and electrically-operated means for reducing the pressure rapidly when the pump is stopped. The pump 22 may be of the internally-meshing gear type driven by an electric motor and when the motor is started up, or shortly afterwards, a solenoid 62 is energized through a means 71 to retract a plunger 64 (see Fig. 1), a valve 54 being closed. Pressure than builds up in a chamber 37 and opens the valve 17 to allow fuel to flow through the delivery 19. When the motor is shut off, the solenoid is de-energized simultaneously, or in timed sequence afterwards, and the plunger takes up the position shown in Fig. 2, a pin 70 forcing open the valve 54 This releases the pressure in the hydraulic circuit opening a return conduit 58 tc a suction chamber 13 or elsewhere. The plunger has appreciable weight and the pin 70 covers some distance before striking the ball valve 54. The pump 22 shown is supplied from the chamber 13 through a strainer 27 and discharges fuel into a chamber 28 and passages 29 and 16. Another duct 30 leads from the chamber 28 to the valve 54. The delivery outlet control valve mechanism 17 contains a sleeve 35 and a piston 36. The passage 16 and chamber 37 are connected. When the piston 36 is moved to the right, Fig. 2, as the valve 17 opens, grooves 39, 40 are gradually opened to holes 41 and to an annular space 42. This allows fluid to flow through the byepass 44, 45 leading through a line 61 to a tank or through a line 60 to the chamber 13. Oil leaking along the driving shaft 21 is led through a duct 46 to slots 47 in the sleeve 35.

Abstract: 413,734. Making bottle stoppers. FRASER, W. P., and FRASER & GLASS, Ltd., Assembly Works, Woodside Lane, North Finchley, London. Jan. 23, 1933, No. 2100. [Class 125 (iii).] Screw-stoppers for bottles &c. are moulded from condensation products of phenol and formaldehyde in heated moulding, elements to form a hollow shell 1, having a circular ridge 3 at the top. A disc 11 of metal &c. is then placed within the ridge to rest on the shoulder 5. The ridge is now turned inwardly to secure the disc, by the application of heat and pressure. A disc of paper &c. may be inserted under the disc 11, or a small quantity of rubber solution &c. may be applied to the shoulder 5, before the disc is inserted. The shell 1 may be annealed before the disc is applied thereto.

Title: Improvements in and relating to drums and like musical instruments
IPC: G10D13/02
Filed: 1945-01-26
Abstract: 626,688. Musical drums. SOMERVILLE, J., (trading as RENO ELECTRICAL & ENGINEERING CO.). Jan. 26, 1945, No. 2155. [Class 88 (ii)] The head of a drum is tensioned by an internal pressure ring spaced from the rim holding the flesh hoop. The pressure ring may be moved against the head which is held by a rim fixed to the shell or the rim may be moved to draw the head over the edge of the shell. A number of concentric rings may be arranged alternately above and below the head, Fig. 24. Numerous arrangements are described and only typical examples have been abridged. The pressure ring of Figs. 1, 3 is pressed against the head by the action of a eam ring 6 on rollers 3. The cam ring is rotated by a roller 33 and a cam 30, the latter being carried by a nut 28 engaging an adjusting screw 26. The cam ring rides on a T-section member 8. The heads may be tensioned separately by rings 2 and the screw 25 for the snare head may be adjusted by means of a rod 27 passing through the screw 26. Pointers 44 indicate the displacement of the cam rings and the tension of the heads. In the arrangement of Fig. 13, the drum is initially tuned by a worm wheel 93 and a rack 91 which abuts against the end of a slot 90 in the cam ring 6. The pitch can be raised further by a cable 97 operated by a pedal or lever. On release, the tuning returns to the initial adjustment. In the arrangement of Fig. 1, the two rings 50 are adjusted simultaneously by means of a toggle action, the blocks 53 being mounted on parts of a single rod 54 bearing right and left hand screw threads. The screw rod 54 and guide rods 56 are mounted on plates 57, 58 and pass freely through slots in the shell so as to permit equality of pressure on the two heads. In a modification, Fig. 22, the ring 50a is connected to the rim 157 by members 156 passing through holes in the shell and the head is drawn over the edge of the shell. In another modification, Fig. 19, the blocks 53 are initially adjusted by a nut 141 and a spring 141a, and the pitch is subsequently raised as required by means of a cable 143. In another modification of Fig. 10, the blocks are drawn together by a cable 122, Fig. 16, and are held in a set position by a latch mechanism 125. The latch can be released by a. supplementary cable 129. The latch mechanism may be incorporated in a pedal operated device. Snare mechanism. A snare may be operated by a push-rod 49, Fig. 9, independently of the movement of the pressure ring 2. The pushrod is operated by a rod 46 and a handle 45 of bell-crank lever form. Alternatively the snare may be operated by the lateral displacement of a sleeve 49a, Fig. 9a, slidably mounted on the rod 46a. The Provisional Specification states that damper means may be mounted on the pressure ring and describes connections between the head and the shell involving either bayonet joints or spring blades.

Title: Improvements in metallic filaments for electric incandescent lamps and methods of producing said filaments
IPC: C23G5/04
Filed: 1926-01-26
Abstract: 259,810. Neue Gl³hlampen Ges., (Assignees of Hauschild, M.). Nov. 19, 1925, [Convention date]. Filaments for intensive illumination are produced by winding long-crystal wire into a spiral formation having each turn of triangular or polygonal shape and rotated with respect to adjacent turns so that neighbouring straight sections are angularly displaced. The filament may be wound directly into the finished shape, for example that shown in Fig. 3, the wire being heated to such a temperature that it retains this shape, or it may be wound at a low temperature around two cores a, b, Fig. 1, so that when released, its resiliency causes it to unwind and assume the shape shown in Fig. 3. Lengths of the filament may be arranged axially in the inner space d, or this space may be occupied by a refractory body e, Fig. 4, which itself becomes heated to Incandescence.

Abstract: 276,883. Colecliffe, J., and Colecliffe, R. Feb. 2, 1927. Cracking nuts. - A machine for cracking and shelling nuts comprises a reciprocating cracking-element actuated in such a manner as to apply a pressure gradually to the nut, and on opposing resilient resistance-element. An axial turning movement may be imparted to one or both of the cracking - elements during the cracking operation for the purpose of breaking away the cracked shell. As shown, Figs. 1 and 2, the two cracking- elements 1, 18 have a slight turning movement in opposite directions. The spring- controlled ram or plunger 1 is operated by means of a cam 6 on a collar 11 on the end of the driving- shaft 12. The cam 6 bears against a roller 17 on the end of the ram, and a pin or bolt 4 on the pedestal 2 engages in a longitudinal slot 3 in the ram, part of the slot being inclined to turn the ram after the crushing pressure has been applied. An adjustable seatmember 10 with a conical recess is screwed into the end of the ram and secured by a nut 25. The other cracking-element comprises a seatmember 18 resiliently mounted in a housing 20. The member 18 abuts against a rubber block 22 and has a pin 21 engaging a slot 19 in the housing, the slot 19 being inclined in the opposite direction to the slot 3. A screw 23 acting on the block 22 allows the member 18 to be adjusted axially, and a graduated scale 24 may be provided on the member 18. The surfaces of the recesses on the seats 10, 18 may be ribbed or roughened. The nut-feeding means shown consist of an endless chain conveyer 27 arranged at right-angles to the cracking-elements and intermittently operated to bring the nuts successively into alignment with the cracking-elements. Forked extensions 28 are provided on the links of the chain to receive the nuts, and side plates 29. which may be adjustable, are provided for part of the upper run of the chain.
