Title: Improvements in and relating to moulding machines
IPC: G05D9/04
Filed: 1958-06-19
Abstract: 853,164. Casting metals. HANSBERG, F. June 19, 1958 [July 13, 1957], No. 19725/58. Class 83 (1). [Also in Groups XXIX and XXX] Sand from a container 7 flows past a sliding valve 25 into a hopper 5, the flow being assisted by a vibrator 8, until the level of sand in the hopper 5 reaches a diaphragm valve 18, at which point the pressure of the sand causes the valve to flex to prevent further discharge of air into hopper 5 from said valve. The resultant increased air-pressure in the associated pipe 17 operates a pneumatic relay 19 to permit compressed air from pipe 20 to flow through a pipe 21 to cause a piston 23 to move rightwards and to flow through a pipe 28 to cause a piston 29 to move rightwards also: This causes a slide 25 to move rightwards to prevent further inflow of sand, and also causes vibrator 8 to cease. The sand in hopper 5 is then discharged into a mould by compressed air, and the cycle is again commenced. The valve 18, Fig. 4, receives air at reduced pressure through a pipe 16, which air passes into diaphragm 48 and out into hopper 5 through holes 17a. The effect of sand rising to the predetermined level is to force plug 50 of the diaphragm rightwards to block bore 47, and thus to increase the air pressure in pipe 16. Alternatively, a piston may be secured to the diaphragm. The increase of air-pressure in pipe 16 causes a diaphragm 31 to flex to lower stem 32. This permits air from pipe 20 to pass via bores 37, 42, to the left end of piston 39 to move said piston rightwards. This moves slide 40 rightwards so that air from 22 is vented to outlet 30, whilst air from 20 passes to pipe 21. This reverses piston 23. The air supply in pipe 14, at six atmospheres, is reduced in pressure before it reaches pipe 16 by a differential piston 50, the rear face 54 of which can seal bore 56. The piston reciprocates slightly under the pressures shown, and thus passes air to pipe 16 at approximately 0.2 atmospheres. Specifications 672,487 and 763,036 are referred to.

Title: Improvements in impulse senders for use in telephone or like systems
IPC: H04M1/272
Filed: 1939-07-08
Abstract: 531,693. Impulse transmitters. MERCER, R., (Associated Electric Laboratories, Inc.).  July 8, 1939, No. 19975. Drawings to Specification. [Class 40 (iv)] In a dial transmitter, successive operations of the finger-hold plate bring about a cumulative setting movement and a .further releasing operation by the user allows the transmission of the dialled digits as a single train of impulses. The dial mechanism associated with the fingerhold plate has no impulse-generating parts and transmits its successive setting movements by a pawl and ratchet coupling to a second dial mechanism whose return movement is normally prevented by a detent under the control of a releasing lever. An arm carried by the ratchet co-operates with a toothed cam to limit the cumulative setting movement to three complete revolutions. The setting pawl is withdrawn from the ratchet in the normal position of the finger-hold plate to allow the return movement of the second dial mechanism when the releasing lever is operated. The dial is particularly useful in a small telephone system employing 25-point switches, and in such a system the releasing lever is preferably controlled by the switch-hook. It is convenient also in systems in which power is derived from a magneto generator, which can readily be operated at the same time as the releasing lever.

Title: Improvements in or relating to methods and means for balancing cables and land lines
IPC: H04B3/40
Filed: 1927-07-27
Abstract: 301,340. Tinsley, H., and Gall, D. C. July 27, 1927. Addition to 262,991. Duplex telegraphs; artificial lines and balancing networks. - According to the parent Specification, errors in adjustment in detail of impedances distributed to form an artificial line, which forms part of a duplex bridge having equal capacity ratio arms, are determined by temporarily introducing additional impedances into the bridge and observing the values of these which will produce balance at various frequencies; the effect of capacity adjustments at various points in the artificial line is determined separately from the effect of resistance adjustments. According to the present invention, alternating current is applied to the apex of the bridge, and the ratio arms, which may be unequal and need not be capacitative, are adjusted to restore balance at various frequencies. The impedance errors in the artificial line are thus obtained as two complex functions in quadrature, instead of as pure reactance and pure resistance reapectively. Thus let Za, Fig. 8, be the impedance of the artificial line and Zc that of the cable: let Zc - Za = dZ + jd<1>Z, say, let the ratio arms contain condensers of capacity c, let Zc = Za. Then if a, Fig. 1<a>, be the locus of the vector impedance of the cable and b that of the artificial line, and if the points x, y represent the impedances at a selected frequency, then the " impedance error " yy, (or dZ) can be compensated by introducing additional capacity #c into one ratio arm, where dZ = Z#c/c, while the " quadrature error " y<1> (or jd<1>Z) can be compensated by adding a resistance #r, where jd<1>Z = Z#C. #r, and w = 2A times the frequency. From the values of 8c and #r at various frequencies it is possible to calculate "impedance error" and '' quadrature impedance error " as functions of frequency, examples of these functions being shown in Fig. 1<b>. The curves so obtained can be analysed into component curves of the type described in the parent Specification, or can be used in other ways in calculating the required balance adjustments. Instead of the adjustments #c and #r already described, other shunt and series adjusting impedances may be employed, and an adjusting resistance may be connected in series with the artificial line, while the ratio arms may be inductive, resistive or capacitative; various modifications of this kind are illustrated in Figs. 2 - - 6 (not shown). Alternatively use may be made of the bridge shown in Fig. 7, in which the mutual inductance M and resistance R are adjustable.

Abstract: 1,078,908. Fluid-pressure servomotor systems. OHIO BRASS CO. May 6, 1966 [May 7 1965], No. 20226/66. Heading G3P. Also in Divisions F1 and F2] The axially movable spool 39 of a closed centre spool valve 10 having an inlet 14 connected to an automatically adjustable variable volume hydraulic pump 12, an outlet 46 connected to a reservoir R and distributing ports 16, 18 connected by flexible lines (28, 30) Fig. 2 (not shown) to opposite ends of a double acting hydraulic piston and cylinder motor (20) is variably displaced to an operative flow control position against biasing springs 60, 60a by fluid-pressure admitted from the inlet 14 past one or other of poppet valves 68, 68a to an associated chamber 64, 64a surrounding stepped ends 56 of the spool 39; the relevant poppet valve being unseated by a variable fluid-pressure signal generated by a manually operated remote means 34 connected to said valves by lines 35, 35a. The signal generator 34 forms a pair of master cylinders of a telemotor system having the poppet valves as the slave units. To extend the motor piston the actuating lever 98a of the signal generator 34 is swung clockwise to depress a plunger 86a against a spring 100 and into a chamber 92a to isolate the latter from a surrounding vented chamber 85a. The resulting pressure pulse transmitted through line 35a unseats poppet 69 and allows inlet pressure fluid to flow via a passage 37a and an orifice 80a to chamber 64a to move spool 39 to the left and thereof connect inlet passage 37 to port 16 and to connect port 18 to reservoir R. An axial bore 104 in the spool has a central lateral port 110 open to reservoir and restricted lateral end ports 108, 108' open to chambers 64, 64a for bleeding of same. When pressure in chamber 64a suffices to displace the spool the desired amount the resulting back pressure unseats poppet 69 and the fluid trapped in line (35a) which may be of deformable plastic material reacts against the lever 98a and provides proportional "feel" to the operator. A modified signal generator (34') Fig.7 (not shown) for providing "feel" when using relatively rigid material for lines (35, 35a) comprises a hollow spring-biased plunger (185) containing at its lower end a solid spring-biased piston (190) which when the lower end of the plunger (185) rotates chamber (92') from chamber (85a) the pressure generated in space (92') reacts against piston (190) and its biasing spring (194). Each slave unit may comprise a piston (124) Fig. 4 (not shown) having a peripheral groove (126) which when in register with a port (122) allows inlet pressure fluid to pass through a transverse passage (128) and an axial passage (128a) to a port (120) leading to the associated space (64, 64a). In a further modification a floating slave piston (152) Fig. 6 (not shown) bears on a spoollike plunger (158) having peripheral recesses (164, 168) and transverse and axial passages (170, 170a) whereof the fluid inlet pressure may be transmitted through an outlet port (174) to an associated space (64, 64a).
