Title: Improvements in or relating to methods of manufacturing pistons and pistons formed thereby
Inventor: CLARY HARRY EARL
IPC: B23P15/10
Filed: 1966-07-07
Abstract: 1,092,720. Making pistons. TRW Inc. July 7, 1966, No. 30652/66. Heading B3A. A method of making piston comprises forming a piston blank having a head, a depending skirt and a pair of opposed pin bosses in the skirt, forming an open top annular groove in the head, inserting therein a core ring shaped to the size of a desired oil gallery, upsetting the piston head to close the groove, forming a weld bond to close the groove, drilling a drainage hole from the closed groove to the interior of the skirt and removing the core material therethrough. The piston blank may be forged from a high silicon content aluminium alloy to provide a ridge 24 in which is machined a groove 29. A core ring 32, preferably of zinc or an alloy thereof and coated with a refractory material, is inserted in the groove and the ridge 24 is upset to form a flat crown 22a. A V- groove 39 is machined along the junction line formed in the crown and filled with weld material 41. Finally holes 44 are drilled and the core ring is melted and drained therethrough during heat treatment of the piston. The oil gallery 43 may be cleaned by flushing with a nitric acid solution. When using an easily forged aluminium alloy the groove 39 may be formed in the initial forging step. The groove (67) may be of triangular cross-section in which case an upstanding cylindrical projection (66) within the inner circumference of the groove is forged so as to close the groove and form the piston crown, Figs. 11, 12 (not shown). The junction line (79) extends radially outwardly and the weld material is deposited in a circumferential groove (34) in the side of the piston head. In a further embodiment, the triangular shape of the groove is modified and a back-up ring 161 is fitted into the groove with the core ring. The V-groove 162 may extend into the outer circumference of the ring 161. Alternatively the back-up ring may extend along the vertical side wall of the groove or partially along this wall and along the top of the groove, Figs. 20, 21 (not shown).

Title: Improvements in weight recording apparatus of the type controlled by a hand operated steelyard
IPC: G01G1/26
Filed: 1929-10-10
Abstract: 336,781. Brown, S. C. Oct. 10, 1929. Printed and permanent records, apparatus for giving.-In a recording weighing machine of the kind having a steelyard fitted with hand-operated poise weights equipped with type-locating mechanism, the customary hand-operated minor poise weight is replaced by a combined automatic weighing resistant and type-numeral locating- mechanism for counterbalancing and recording the minor increment of weight. The arrangement may be adapted to the weighing machine described in Specification 28626/12 wherein a record can only be obtained after the steelyard has been brought to equilibrium and enclosed by a shutter. As shown, the steelyard 1 mounted on a fulcrum 1<a> is provided with two major poise weights 2, 7 connected by the usual racks to type wheels 6, 8. The minor order of weight is balanced by an automatic resistant, for example a spring 13 connected to the steelyard bv levers 21<a>, 16 and a rod 19. A weaker spring 19<b> may act in opposition to the spring 13. On the fulcrum of the lever 21a is secured a type sector 21. By depressing the printing lever 11 a record may be obtained on a ticket 12. Ratchet teeth 29 on the type sector, and a lever 30 connected to the printing handle ensure alignment of the type. Two fixed pointers 26, 27, and an index 29a on the steelyard indicate to the operator the range of the automatic resistant. Graduations 21<d> indicate the minor weight readings. The type sector may carry, beyond the type figures, hieroglyphics designed to intimate when printed, that the record is fallacious. When the arrangement is adapted to the steelyard-enclosing shutter device described in Specification 28626/12, the shutter (not shown) is connected by a rod 33a to a locking bolt 33. If the steelyard is situated within the range of the automatic resistant, that is, equilibrium is correctly established, the locking bolt enters a gap 34 during the shutter-closing movement and permits a record to be obtained.

Title: Improvements in or relating to the manufacture of thermionic valves
Inventor: BREWSTER HARRY GEORGE
IPC: H01J21/36
Filed: 1947-11-20
Abstract: 655,568. Thermionic valves. HIVAC, Ltd. Nov. 20, 1947, No. 30856. [Class 39 (i)] A method of manufacturing a thermionic valve of the type described in Specification 619,771, having a series of generally planar electrodes disposed in stacked relation with interleaved planar spacing-members of sheet insulating material includes the step of so shaping at least one of said spacing members that it co-operates with at least one of the electrodes during the stacking assembly of the valve elements so as to ensure correct location of said spacing member with respect to said valve electrodes in both transverse and longitudinal directions of the plane of said spacing member, as well as effecting the requisite spacing of the electrode from another electrode. The jig employed in the assembly of the valve elements consists of a flat base-plate upon which are mounted four L-section pillars c, Fig. 3(i), projecting upwardly and defining a rectangle, and two blades d. An anode part 10 having side portions 12 bent upwardly at right-angles is first placed between the blades d, followed by a mica spacing frame 13, grid electrode 17, of the type described in Specification 619,770, [Group XXII], spacing frame 21, and filament subassembly 23 of the kind described in detail in Specification 655,567. Elements 13, 17 and 21 each have four corners which fit snugly into the pillars c. Further elements 21, 17 and 13 are then added, in that order, followed by a second anode part 28. The completed stack is then compressed and the upper ends of the side portions 12 bent over the anode part 28, and preferably welded to the latter to hold the assembly in clamped relation. During the compression of the various parts, the filament wire 25 becomes drawn into the notches 22 of the adjacent spacing frame to provide exact location of the filament and to damp it against vibration. The aperture 14 of each spacing frame 13 is made longer than the adjacent anode zone to provide openings for the removal of occluded gases from the active electrode region. The outwardly-projecting lugs 15 on spacing- member 16 serve as resilient fingers, engaging with an positioning the assembly within the valve envelope, which may be circular, oval, or rectangular in section. If desired, all the spacing members may be similar to the frame 13. The second anode part 28 may be omitted and the two bent-over portions 12 of the first anode part 10 arranged to meet edge-to-edge to form the second anode zone. A tetrode, pentode, or valve having a greater number of electrodes may be constructed by suitable addition to the number of grid electrodes and interposed spacing frames.

Title: A fluid flowmeter
Inventor: HARRIS WILLIAM RICHARD
IPC: G01F1/684
Filed: 1969-06-18
Abstract: 1,219,710. Measuring fluid flow rate electrically. STANDARD TELEPHONES & CABLES Ltd. June 18,1969. No.30936/69. Heading G1N. The rate of flow of a fluid through a conduit 1, Fig. 1 of heat conductive material is determined from the heat dissipation differential between two heated thermistors 5, the first in assembly 2 in thermal contact with the conduit 1, and the second in assembly 3 in thermal contact with the fluid via a probe 13 whose cross-sectional area is varied along its length to obtain uniform heat dissipation to the fluid along its length. Each thermistor 5 is maintained at a constant temperature and thus at a constant resistance by automatic control of the heating current. The power fed to assembly 2 is indicative of the temperature of the fluid and conduit and the power fed to assembly 3 additionally compensates for the heat removed by the flowing fluid. Hence the power difference is indicative of the fluid flow rate. In a modification, Fig. 2 for use with flowing liquids, the probe 13 of assembly 3 is located outside the conduit 1 upstream of a restriction 16, the excess pressure on the upstream side of the restriction causing the liquid to rise into the assembly 3 by an amount dependent on the rate of liquid flow. The flowmeter may be combined with a further assembly similar to assembly 2 for measuring the temperature of the fluid at another location to determine the temperature change in the fluid and the total heat supplied by, e. g. a central-heating system.
