Title: Improvements in or relating to devices for determining the hardness of materials
IPC: G01N3/42
Filed: 1953-07-09
Abstract: 748,185. Testing physical qualities of materials. FUCHS, R., [trading as FUCHS, ERSTE NAXOSSCHMIRGELFABRIC DEUTSCHLANDS, P.]. July 9, 1953 [July 10, 1952; Jan. 15, 1953], No. 19108/53. Class 106 (2). A hardness-testing device, Fig. 1, has a chisel-shaped tool 50 that is reciprocated and rotated, a balancebeam 36 for wholly or partly compensating the weight of the tool holder 35 and its associated parts, means exerting a substantially constant force on the tool holder 35 in the direction of penetration and a device for determining the work performed by the tool during a test. An electric motor 16 drives a shaft 24 through gears 22 and 23. On the shaft 24 is an eccentric 27 universally connected to a rod 28. The free end of the rod 28 has a ball and socket connection 29 to a bell crank lever 30 rockable on a pin 31. The other end of the lever 30 supports the tool holder 35 on a pin 32. As the shaft 24 rotates, the eccentric 27 oscillates the rod 28 to rock the lever 30 and cause reciprocating motion of the tool holder 35. Alternatively, a step gear may be introduced whereby a turning movement of the tool is effected either in its upper dead centre position or its lower dead centre position. The force exerted during a test may be that due to either the weight of the tool holder 35, or a leaf spring 69, Fig. 2, acting on the balance beam 36. Measuring work done. The work done during a test may be determined by a counter 47 indicating the number of strokes performed for a certain depth of penetration. This depth is set by a collar 46 on the tool holder 35, the movement of the collar as the test proceeds causing a pivoted lever 55 to switch off the motor 16 at the required depth of penetration. The switch is reset by a press button 63. A pressure indicator may be placed between the tool holder 35 and the chisel 50. In Fig. 9, the pressure indicator is a block of piezo-quartz 89 in the form of a bending element. The electric potential set up in the quartz 89 due to the pressure thereon is passed to a two-stage intensifier 95. The first stage is connected to a maximum reading voltmeter 96 and the second stage is connected through a condenser 98 to a voltmeter 99 giving a mean value of the pressures during a test. Alternatively, hydraulic, pneumatic or mechanical pressure indicators may be used. An air compressor 18 draws air through an opening 111 and forces it out through the annular clearance between the tool holder 35 and the lower bearing 43 to blow away chisel dust. The device 12a, Fig. 10, may be held by a support 101 and may act on test specimens, for example a grinding wheel 103, supported by rollers 110 and a pressure plate 109, and rotatable about an axis 108.

Abstract: 724,237. Welding by pressure. TRIANGLE PRODUCTS, Ltd. Aug. 5, 1953 [July 30,1952], No. 19211/52. Class 83 (4). In a portable spot-welding tool comprising a body part 10 housing a transformer, the secondary of which is connected to a pair of tong electrodes 12, 15, brought together by a lever and link system, a pillar-type hand grip 13 is provided, having an adjacent lever 17 forming part of the lever and link system, below the centre of gravity of the tool when the latter is substantially horizontal with the hand grip below the body part. The fixed electrode 12 is held in a clamp 11 on the body part and the movable electrode 15 is held in a clamp 14 pivoted to the body part. The lever 17 is pivoted to the clamp 14 and to one end of a link 18 moving in a slot in the grip 13 the other end of which link rests on a screw 20 in a hole 19 in the grip. A pin 29 on the link engages a slot 21 and prevents it leaving the hole. Manipulation of the lever 17 into a locked position closes the electrodes and a spring metal arm 28 releases the lever 17. The screw 20 allows adjustment for material thickness. The rear end of the rod may be held against the body.

Title: Improvements in methods of and apparatus for shaping curved surfaces
IPC: G10D3/02
Filed: 1930-06-24
Abstract: 361,938. Carving wood. GRUBER, L., 246, West 106th Street, New York, U.S.A. June 24, 1930, No. 19273. [Class 145 (i).] Wood pieces of irregular outline are shaped on both surfaces to sections having the shapes of conic sections. Cutters carried on a frame borne by pivots 25 and links 43, simultaneously cut both faces of a violin sound board, the pivots 25 being controlled by arms 22 pivoted at 28, by brackets 21 sliding vertically and by links 45, 45a. The thickness of the work is governed by cam 55. The cutter frame is raised and lowered by the hand-wheel 46a through the train 46c, 49, 50, 51, 53 ; on the upstroke the work is cut and on the return stroke the work carrying frame is rotated slightly by gearing 59, and the pivots 28 are reset. This is performed by first releasing the previous setting on rack 32 by rods 61b, 62a, and then moving the pivots by the train 64, 65, 66, 66a, 29. An outline cam 33b engages a follower 78a to move pointers 80, which, for each cut must be made to agree with pointers 79 controlled by the cam groove 77, thus ensuring that the appropriate setting of pivots 28 is obtained. The direction of motion of wheel 64 is controlled by pawls 72, one of which is held out of action by a reversing gear. The tools are driven by motor 26d through the belt 26a and gearing. Variation in the ratio of links 45, 45a enables the cutters to trace parabolas, ellipses, or hyperbolas.

Title: An improved method of utilising electrical currents
IPC: G05B11/01
Filed: 1930-06-25
Abstract: 364,075. Thermionic valve relays. GEFFCKEN, H., 62, Steinstrasse, and RICHTER, H., 3, Wiederitzscherstrasse, both in Leipsic, Germany. June 25, 1930, No. 19404. Convention date, June 25, 1929. Void [Published under Sect. 91 of the Acts]. [Class 40 (v).] An input current, which may be of thermoelectric or photo-electric origin, is used to influence the filament emission of a two-electrode or threeelectrode valve, the resulting voltage variations in the output circuit of the valve being applied either to a " threshold " device such as a glowdischarge tube or a triode, which in turn operates a relay. The heat-inertia of the filament prevents momentary or fortuitous impulses from operating the relay, whilst the saturation factor of the valve limits the output current to safe valves when employing a sensitive type of relay. In Fig. 2 the input is applied to the filament 1 of a diode 2, and the resultant voltage-change at the point 4 operates the glow-discharge tube 5 through a coupling resistance 6 and condenser 7. A mechanical relay 8 is inserted in the output circuit as shown. In Fig. 3 the initial temperature of the filament 1 is adjusted to a critical point by balanced resistances 10, 12, a third resistance 11 keeping the terminals 13, 14 at an equal potential. Voltage variations due to the input are applied through a resistance 15 to the grid of a triode 16, to operate the relay 17. Fig. 4 shows a balanced arrangement of two triodes 18, 19 with a Wheatstone-bridge input 27. Bridge current flowing from 25 to 26 will increase the heating current of valve 18 and decrease that of valve 19. Glow-discharge tubes 28, 29 in the output circuits operate differentially upon relays 33, 34 to turn an escapement-wheel 37, which may, in turn, be utilized to indicate, record, or regulate the existing conditions in the bridge 27, for instance a chemical process or other effect causing a variation of one of the bridge arms. The residual voltage in the condensers 30, 31, after the glowdischarge through the tubes 28, 29 has ceased, is completely discharged by contacts 35, 36 operated by the relays 33, 34. A circuit is shown in which the operating potentials are derived from AC or DC mains, and automatic switching means are provided to allow for the intermittent discharge of condensers in the plate circuit of the diode valves, the latter being in series with threeelectrode amplifiers operating the final relay.

The cord 19 is secured to a lug 9<c> of the bar and passes through the link 8 and ove,r a part of the pivoted catch 13, the other end of the doubled cord being attached to the end of the bar. On pulling the cord 18, the stay bar is first swung outwardly and then engages with the catch 13, as shown in Fig. 4. By pulling also the part 18 of the cord, the catch is first depressed to permit the window to be opened wider by continuing the pull on the other end 19 of the cord.
