Title: Fluid-flow control valve
Inventor: HAJMA LOUIS GEORGE
IPC: F15B13/01
Filed: 1966-08-04
Abstract: 1,082,708. Valves. PARKER-HANNIFIN CORPORATION. Aug. 4, 1966, No. 34992/66. Heading F2V. A valve controlling the flow and exhaust of fluid to and from the opposite ends of a motor 4 comprises a spool valve 21 reciprocable in a bore to control the connection of motor ports 15 to supply and exhaust ports 11, 19. The valve lands have notches 28, 29 to regulate the flow. The two ports 15 are connected to the opposite ends of the motor through check valves 35, 36. The valve 36 co-operates with a seat 34 and has a through port controlled by a pilot valve 41, the valve 36 controlling the flow from the lower end of the motor which, due to the load, may be under a high pressure. When the spool 21 is moved upwards, the supply is connected to the upper port 15 and flow takes place past the valve 35 to the motor. When the pressure rises sufficiently, a piston 45 is moved down to cause a rod 46 to open the pilot valve 41. As the piston 45 moves further down, the rod 46 engages the valve 36 and moves this valve to open a port 40 and allow added flow from the lower end of the motor. The piston parts 47 of piston 45 engage in sleeves 31 to provide a dash-pot effect to prevent chattering.

Title: Improvements relating to refrigerator cabinets
IPC: F25D23/12
Filed: 1954-12-03
Abstract: 789,452. Refrigerators. GENERAL ELECTRIC CO. Dec. 3. 1954 [Dec. 11, 1953], No. 35109/54. Class 29 In a refrigerator having a butter compartment 7 mounted in the insulation of a wall e.g. the door, the closure 18 being on the inside panel 9 of the wall, heat is transmitted from the outer panel 10 to the rear wall 14 of the compartment through a body 22 of insulating and conducting material e.g. a mixture of mineral wool and glass fibres. Moisture condensation may be prevented on the outer panel 10 by disposing the body 22 also on parts of the sides, top and bottom of compartment 7 so that it covers an area of panel 10 larger than the rear wall 14. The heat flow may be equalized by having a higher proportion of heat conducting material towards the edge of body 22 than in the central part. To vary the temperature, a knob 20 is turned to cause cam 36 to force a plate 34 away from the rear wall 14 to compress the body 22 and leave an insulating air space at the rear of the compartment. The closure 18 comprises inner and outer spaced panels 30, 29 and a heat reflecting plate 32. In a modification, Fig. 3, the temperature control is omitted and the body comprises a central part 22a of the mixture and a surrounding part 40 composed solely of heat-conducting material.

Title: Multi-layer wired substrates for multi-chip circuits
IPC: H05K3/34
Filed: 1975-08-27
Abstract: 1485569 Printed circuits SIEMENS AG 27 Aug 1975 [10 Sept 1974] 35275/75 Heading H1R In fabricating a multilayer wired substrate for a multistrip circuit a ceramic carrier 1 is perforated by a laser beam to form through holes 4, and both sides of the carrier are vapour coated in vacuo with a layer 5 of Ti overlain by a layer 6 of Au also extending to the walls of the holes. Photoresist layers 7, 8 not covering the holes are applied to the faces of the carrier, and covered by a mask which is exposed over the perimeter zones of the holes, developed, and removed; after which Au layers 9 are electrolysed on to the perimeters and hole walls. The photoresists are removed and the unreinforced parts of layer 6 and underlying layer 5 are etched out in successive solutions (Figs. 3, 4). Thereafter the ends of the holes at the lower face are sealed with Au paste under pressure over a silk screen template and heated to consolidate (Fig. 5, not shown), after which thick film wiring is impressed on the lower face 3 by silk screening on insulant layer 11 with square windows registering with the closed ends of holes 4, after which thick film wiring is silk screened on layer 11 to define alternate conductor path layers 12, 13, 14 and insulant layers 15, 16, 17 (Fig. 6); the assembly being subsequently heated to consolidate. Metal pins can be soldered into the wiring for external connections. A Ti base layer is then vapour deposited in vacuo on to the upper face 2 and overlain by vapour deposited Cu (Fig. 7, not shown) and a photoresist layer is applied to the face, exposed through a mask, and developed to present a negative image of a required thin film wiring structure. A layer 21 of Cu followed by a layer 22 of Ni are electrolytically deposited on the exposed areas of the Cu and Ti layers. The photoresist 20 is removed and a further photoresist layer 23 is applied (Figs. 8, 9) and exposed through a suitable mask and developed so that the thin film circuit structure is only covered at circular areas for later connection. A solder rejecting layer of Cr is deposited on the uncovered portions of the thin film wiring. The photoresist layer is removed, and the Cu and Ti layers are sequentially etched out from the areas not corresponding to the wiring. The connection surfaces not covered with Cr and the flanks of the wiring are electrolessly plated with gold at 25, 26, and layers 25 are dip coated with solder (which is not deposited in the Cr plated wiring surfaces and through hole walls) to produce dome contacts 28 for soldered connection of semi-conductor modules 27 (Fig. 10).

Title: Improvements in and relating to dynamo electric machines
IPC: H02K3/32
Filed: 1922-12-30
Abstract: 213,341. Parsons, Sir C. A., and Rosen, J. Dec. 30, 1922. Transformers.-In a high voltage alternating current generator, transformer or other apparatus, additional insulation is provided around the conductors at higher potentials by grading the sectional area of the core slots with respect to that of the contained conductors so as to leave room for various thicknesses of insulation. Fig. 1 shows slots of common width but varying depth which all contain conductors of the same total section, the arrangement being such as to give an insulation thickness progressively increasing, as the conductor potential increases from A<1> to A<6>. In the form shown in Fig. 2, the slots all have the same section, while the number and sections of conductors per slot decreases, the total conductor section in the pairs of slots A', A<2>. A<3>, being respectively 56, 51, and 40 per cent of the slot section. The reduction in the number of conductors in the slot offsets the decreased thermal conductivity of the thickened insulations, thus tending to equalize the temperatures of all slots. The depth, width and pitch of the slots may be simultaneously varied. Fig. 4 shows the end connections of the coils of one phase of a generator according to the arrangement in Fig. 2. The conductors c<1>, c<2> are respectively adjacent to the phase and earth terminals and the insulation around the conductors in any slot is such as to withstand indefinitely the potential from earth normally induced in that slot, although, excepting the case of an earthed star point winding, it is desirable that the insulation of the whole winding be such as to stand the full machine voltage for extended periods. The thickness of insulation of the end connections K may be graded similarly to that in the slots.

The motor driving the cooling fan of a welding rectifier is fed by the A.C. component of the rectifier output. When A.C. equipment is to be converted for D.C. welding the rectifier unit may be connected to the A.C. welding transformer by two lines only, no additional connections being required for the fan motor. As the motor operates with current of twice the supply frequency, It may be of smaller physical size than would be necessary if it operated with current at the supply frequency. Several circuit arrangements are described, the Figure shows the motor connected in series with a capacitor, across the D.C. terminals. The motor may be connected through a capacitor, in parallel with a smoothing inductance, and may be supplied through a transformer. An arrangement of relays is described which connects the motor only when the welding current exceeds a certain value, and limits the motor voltage by inserting a resistance in its circuit, or changing the transformer ratio, if necessary.
