Abstract: 419,216. Electric signalling systems. AMPENOFF, W. P., 36, Park Drive, Golders Green, and ROCKALL, W. A. E., 11, Hansard Mews, Kensington, both in London. May 8, 1933, No. 13391. [Class 40 (i).] Two pressure gauges connected respectively to the up and down stream pipes of a Pitot tube device are each provided with means to control the section of a beam of light or like rays so as to vary the effect thereof on light sensitive electric devices in circuit with a galvanometer graduated in speed units or adapted to control such circuit through a relay. Two Bourdon tubes u are connected through link, quadrant and pinion mechanism v, w, x to rotary shutters g, h adapted to cut off the light passing through openings k, l from a light source n to selenium cells p, q connected in circuit with a resistance t and galvanometer s. In a modification a mirror on the spindle of the gauge reflects light from a source on to two selenium cells connected in a bridge circuit. When there is no pressure difference the light affects both cells equally, but when a pressure difference occurs a current passes through a relay so as to make the circuit of an electric motor which turns in one direction or the other and through worm and toothed sector gear restores the cells to a symmetrical position with respect to the mirror. Each sector carries an insulated contact moving over the contacts on a rheostat. The rheostats are connected in series with a galvanometer. The current through the bridge is preferably amplified by a thermionic valve device. Instead of the sector carrying the contact the latter may be on an arm fast with a pinion gearing with the sector. Specification 409,317, [Group XXIX], is referred to.

Abstract: 330,709. Electro-Mechanical Brake Co., Ltd., Cadbury, G. N., and Smith, S. May 1, 1929. Fluid-pressure brakes for tramway and other vehicles are controlled by a valve g situated between seatings e, f communicating with inlet and outlet passages and balanced wholly or partly by a piston h on the inlet side, the valve being operated by a solenoid o and lever p against a return spring s. In the end cover a of the brake operating cylinder are arranged passages b, c, d communicating respectively with the interior of the cylinder, the fluid inlet pipe and the outlet pipe and controlled by the valve g adapted in the normal position shown to close the outlet pipe d and open the inlet pipe c. The valve is balanced by the piston h fixed on an extension i of the valve spindle j and moving in a cylinder k, one side of the piston being exposed to the pressure fluid and the other side communicating with the atmosphere by a hole l. To apply the brakes the solenoid o is energized and the motion of the core t is transmitted to the valve stem j by the lever p pivoted at q, to close the inlet c and open the outlet d. The magnet may be connected with the circuit of the rheostatic brake so that both brakes cannot be in operation at the same time. Instead of a single valve a number of valves may be used and the device may be situated at a distance from the cylinder.

Abstract: 1,181,783. Hand shears. WILKINSON SWORD Ltd. 15 March, 1967 [29 March, 1966], No. 13715/66. Heading B4B. A hand tool such as a pair of shears comprises a pair of pivotally-connected blades, a first handle rigid with a first blade and a second handle connected to a second blade through a coupling comprising rolling elements, e.g. balls resting in recesses in the coupling parts, the coupling being effective, when the tool is cutting or shearing a piece of material, to bias the blades towards one another in a direction perpendicular to the direction of their relative movement with a force which is related to the resistance offered by the material. In one embodiment, the coupling between a blade 21 and its handle 23, comprises balls 31 resting partly in recesses formed in a plate 27 secured to the handle 23 and partly in recesses formed in the blade 21, relative movement of the handles causing the balls to ride partially out of the recesses and thereby generate a force in a direction normal to the direction of the relative movement to bias the blades towards one another. In another embodiment, Fig. 5, a blade 41 is rigid with a handle 42 and carries a pivot 43 on which the blade 40 is pivoted. The blade 40 is movable relative to the blade 41 by a coupling 44 comprising balls 49 nesting in frustro-conical recesses 48 in a plate 45 and in the upper face of the blade 40, the plate 45 having a shoulder (55), Fig. 7 (not shown), engageable by a finger 54 on a plate 52 carried by a movable handle 50 pivoted to the handle 42.
Patent GB-188633-A (GB)
IPC: B06B1/10
Filed: 1922-05-16
Abstract: 188,633. Schieferstein, G. H. Nov. 10, 1921, [Convention date]. Machinery, utilizing inertia to obtain movements in.-Reflates to means for the transmission of power or energy through mechanically oscillating systems, stated to be applicable for driving a hammer or a noiseless clock and for the transmission of power from internal-combustion and steam engines, crank drives or reciprocating masses. According to the invention, a mechanical system adapted to oscillate with variable amplitude but with a constant and pronounced natural frequency is driven from a driving system of frequency approximately in tune therewith through an elastic intermediate member adapted to the energy to be transmitted. The escalating system consists essentially of an elastically constrained mass the movements of which under the action of the driver and intermediate elastic member gradually increase from zero to a maximum amplitude. In the arrangement shown in Fig. 1, the oscillatory system comprises a shaft or member a reciprocable in bearings c and constrained by a spring b held between fixed parts d. It is driven by a cram g, connecting rod h and slider i acting through a spring k. The movements of the member a may be transmitted to a second oscillatory system as shown in Fig. 2, in which the second shaft or member a<1> is constrained by spring b' fixed at d'. In the form shown in Fig. 3, the intermediate. elastic member comprises a piston i<1> working in a closed cylinder k<1> which, constrained between springs b, constitutes the oscillatory system. In an alternative form, the cylinder k<1> itself works as a piston inside another olc-sed cylinder. Means for measuring the work or the efficiency of the device are, shown in Fig. 5. The shaft a, constrained by the spring b and driven through the elastic intermediate member k by the crank g, is provided with arms t carrying a rod s with a pencil q<1> by which a record of the movements is obtained on a moving paper strip. A brake block p is also mounted on the shaft a between springs r, r<1>, and is adapted to be adjustably pressed against the shaft. The brake block moves with the shaft until its grip thereon is overcome by the compression of one of the springs, r, r<1>. The movements of the brake block are recorded by means of a second pencil q. Instead of a mechanical elastic intermediate connection, an oscillating surface may produce oscillations in the air which are transmitted to adjacent surfaces. Reference is also made to an arrangement whereby the intermediate elastic member only acts in one direction. Reference has been directed by the Comp. troller to Specifications 2857/02, [Class 139, Watches &c.], 12438/14, [Class 7 (ii), Internalcombustion engines,' Arrangement &c. of], and 146,436, [Class 80 (iii), Link-work &c.].
