Title: Improvements in scissors, shears and the like
IPC: B26B13/04
Filed: 1929-03-19
Abstract: 329,085. Dehn, F. B., (Driest, C.). March 19. 1929. Shear-blades. - Renewable cutting-edges for shear-blades or like cutting-instruments are inserted longitudinally in grooves formed in the shank, Figs. 1 and 2 show the invention as applied to scissors, the form of cutting-edge employed being that shown in Fig. 5. The detachable edge 5 is of tapered cross-section whilst the groove is originally parallel-sided but is rolled to give it a shape corresponding to that of the cutting edge. The edge 5 is inserted at the end 4 of the shank, a projection 7 being formed at the other end which engages with a notch in the cutting-edge, the latter being sprung into engagement to secure the edge longitudinally. In a modification, Figs. 4 and 6, in which the renewable edges are applied to heavy metal shears, the edges 5<1> are provided with inclined or L-shaped slots 16 which engage with transverse pins 15. In this case the edges are inserted directly in parallel-sided grooves, the slight longitudinal movement occasioned by the form of the slots being sufficient to cause a notch at the root end of the edge to engage with a projection 18 formed on the shank.

Abstract: 1,256,222. Moving coil meters. SMITHS INDUSTRIES Ltd. May 23, 1969 [Feb. 26, 1968], No.9280/68. Heading G1Q. The rotatable coil 14 of a moving coil meter embraces an annular core member 20 and moves through both a main air gap 14A, bounded on one side by a planar face of the annular core 20, and an auxiliary air gap 14B formed between the core 20 and an outer magnetisable annular shell 24, the outer shell 24 forming part of an auxiliary flux path of adjustable reluctance in shunt with the main air gap 14A. The main magnetic circuit preferably comprises the annular core 20, a yoke 18, an annular base 19, a generally annular permanent magnet 17 fixed by epoxy resin to the base 19 and having a cut-away portion that fits around the yoke 18, and pole piece 21, although in a modification the permanent magnet is provided by a bar magnet in the position of yoke 18. A portion 29 of the annular core 20 is removable to allow removal of the coil 14. The auxiliary flux path includes an adjustable shunt 27, mounted on the yoke 18, and the cup-shaped shell 24 which forms with the annular core 20 two auxiliary air gaps 14B, 14C through which the coil 14 moves. The meter is said to have a linear response because the air gaps 14A, B, C through which the coil moves are totally enclosed. The shell 24 has, adjacent the yoke, a cut-away portion, an edge 24A of which forms with the shunt 27 an air gap which can be varied to adjust the reluctance of the auxiliary flux path and hence calibrate the meter. The bearings 11, 12 for the spindle 10 are preferably mounted on soft iron bracket 23 and aluminium bracket 22 respectively, the latter also having a projection 22A which limits movement of the shunt 27. Alternatively, the coil 14 may be mounted near one end of a spindle which is supported in a bearing arrangement disposed above the magnetic circuit assembly. The spiral springs 15, 16 are anchored to tags 15A, 16A, the angular position of the latter being adjustable. Limit stops 30 for the pointer 13 are attached to the upper bearing bracket 23.

Title: Means for operating trip-free electric circuit breakers
IPC: H01H3/32
Filed: 1944-05-17
Abstract: 576,872. Automatic circuit-breakers. ENGLISH ELECTRIC CO., Ltd., and HARVEY, J. A. F. May 17, 1944, No. 9478. [Class 38 (v)] A circuit-breaker is arranged to trip during closing by the reversal of an inertia member, spring-connected to the closing mechanism, if the closure movement is abnormally slowed up or reversed. To close the breaker from the Fig. 1 position the pivot R, connecting the links A, B, is forced upwards, causing the contact operating link C to rotate counterclockwise about fixed pivot E until the toggle A, B, D is overset. Clockwise rotation of the trip bar J releases the hook D1 and breaks the overset toggle. Link B is pivoted at S on link D, having a fixed pivot F, and has an inertia member L pivoted to it at K and biased by the spring Q so that surface L2 is normally in contact with link B. If the breaker is prevented from closing normally, the inertia member L momentarily compresses spring Q, which then reverses its motion, causing teeth L to force the pawl T to the right, so operating the trip mechanism. If the deceleration of link B is very rapid the surfaces B1, L4 make contact, preventing damage to spring Q and causing immediate tripping as member L rebounds. In the fully-closed position the teeth L1 move clear of the pawl T. The Provisional Specification also refers to solenoidclosure.

Title: Improvements in and relating to gaseous electric discharge tubes applicable as high frequency oscillators
IPC: H01J17/56
Filed: 1935-03-28
Abstract: 457,704. Discharge apparatus ; generating circuits &c. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London. March 28, 1935, No. 9698. Convention date, March 28, 1934. [Classes 39 (i) and 40 (v)] High-frequency apparatus such as generators of oscillations of frequency of 300,000 kilocycles or more include an electric gas or vapour discharge device with a grid separating its envelope into two compartments which contain respectively the anode and cathode and which intercommunicate only through the grid openings, the device operating with anode and cathode plasmas separated by a continuous positive ion sheath on the grid. Variations of potential on the grid control the flow of electrons between the plasmas whilst leaving the degree of ionization constant. The device is filled with gas or vapour at a pressure sufficient to allow the formation of a plasma but insufficient to impede seriously the movement of electrons, mercury vapour at À1-2 microns or helium or neon at 1 mm. or other rare gas such as argon may be used. The grid 13, Fig. 1, of uniform mesh extends across the envelope 10 between the anode 11 and cathode 12 and is maintained negative. Coils 18, 23 in the anode and grid circuits are coupled together to generate oscillations at a frequency controlled by the tuning of the circuit by a condenser 24. The ionic sheath moves back and forth as the grid voltage oscillates and provides an on-and-off control allowing electrons to pass for a small portion of each cycle, the intensity of the electron flow when thus allowed being mainly limited by the cathode emission. Oscillations are efficiently generated with the duration of each cycle much less than the deionization time of the device. The auxiliary anode 11<1> to maintain the cathode plasma may be omitted. The supporting edge of the grid may be protected from sputtering by a glass shield. In modifications, the grid is a cylinder closed at one end and surrounding the cathode or anode. In another oscillator which can also be modified for use with input and output circuits, metal bands 27, 28, Fig. 4, partially or wholly surrounding the envelope form capacity couplings with the cathode and anode plasmas. The circuits between the parts 13, 27 and 27, 28 are coupled together, for example, by an inductor 37 tuned by a condenser 41. The potential of the grid 13 is positive before the plasmas are formed and drops when ionization starts, a resistance being connected for this purpose in the bias circuit of the grid or a positive starting voltage being supplied by a switch 44. The band 28 may be about the anode or as shown near the grid and a further band 26 about the anode plasma may be connected in the latter case to the band 28 through a circuit 39, 40 tuned to a harmonic of the frequency of the circuit 37, 41 to feed very high frequency oscillations to an output circuit 42 connected to a dipole antenna.

No. 9883/49 [A Specification was laid open to inspection under Sect. 91 of the Acts, April 6, 1950.] Classes 69 (i) and 69 (ii) In a loading conduit system for delivering liquids into containers of the kind which is provided with a loading arm which is swingable vertically, hydraulic means are provided whereby when the arm is lowered for delivery of liquid it remains stationary but returns to its out-of-use position under the influence of counterbalancing springs when the hydraulic means is operated by hand manipulation of a valve. A swingable arm 13 connected to a standpipe and having a delivery pipe 14 has arranged therewith counterbalancing springs 24 and the hydraulic means comprising a cylinder 25 and a piston 32 mounted on a piston rod 24 fixed at both ends. The cylinder 25 is provided with a bye-pass 37 controllable by means of valves. In operation when the arm 13 with delivery conduit 14 is lowered the cylinder 25 moves outwardly relatively to the piston 32 displacing liquid 0 in an anticlockwise direction, pressing back valve 43 against its weak spring 47. When the arm 13 &c. has completed its downward movement displacement of the liquid ceases and the valve 43 closes resulting in the arm 13 &c. remaining in its lowered position. When it is desired to return the arm 13 etc. to its upper and inoperative position cord 61 is pulled causing valve 52, through lever 58 and spindle 55, to be opened and thereby putting the cylinder 25 and bye-pass 37 into communication through passage 41 and adjustable passage 49. The retraction and counter-balance springs 24 then raise the arm 13 etc. causing the liquid 0 to move from one side of the piston 32 to the other through the bye-pass in a clockwise direction.

Abstract: A hydraulic door opening or closing device comprises a hydraulic fluid pump motor (7) having two ports connected to each end of integral dual manifold (8, 9) and operating cylinder apparatus (10) by way of two branch fluid lines (11, 12). One branch line is fluidly connected to a particular end of the operating cylinder by way of a directional flow valve (17, 18). The other branch line to the same end of the cylinder is fluidly connected to the cylinder by way of an associated manifold (8, 9). Fluid communication with the cylinder through the manifold (8, 9) is accomplished by providing a plurality of valved openings (21-30) linearly disposed along the end of the cylinder between the manifold (8, 9) and the cylinder (10). As a piston (14) of the operating cylinder (10) passes these openings, a door coupled to the piston (14) is automatically slowed as fluid on the drive side of the piston is returned through the openings to the hydraulic fluid pump (7). A simplified control circuit coupled to the device provides three modes of operation, an opening mode, a closing mode and a reversing mode from door opening to door closing.
