Title: Improvements in or relating to processes of pumping artificial silk spinning solutions
IPC: F04C15/00
Filed: 1928-07-12
Abstract: 322,778. British Celanese, Ltd., Bower, J., and Yorke, W. July 12, 1928. Channels and reservoirs in rotary pumps.-In a process for pumping artificial silk spinning solutions, the bearings of the pump are lubricated by causing a portion of the solution being pumped to flow from the delivery side of the pump to the inlet side via the bearings. As shown in Fig. 1. wherein the shafts 4, 7 of a gear pump run in journal bearings 5, 6, 8, 9, spinning solution flows from the delivery side of the pump to the bearings 5, 6 through channels 20 formed in the casing cheeks, and is carried outwards along the bearings by spiral grooves 16, 17. From the outer ends of the bearings the solution fows through passages 14, 15 to the bearings 8, 9 and is carried inward by spiral grooves 18, 19 to channels 22 in the casing cheeks communicating with the inlet side of the pump. The channels 20 may be replaced by passages, controlled by needle valves, leading to annular grooves in the bearings 5, 6. Where the gear shafts run in ball or roller bearings 5, 6, 8, 9, Figs. 4, 5, and 7, mounted in chambers 10 - - 13, solution passes to the chambers through passages 20, 21 communicating with ports 15 in the casing leading from the delivery side of the pump, the ports being controlled by needle valves 17. The solution passes from the bearing chambers through passages 24, 25 communicating with ports 23 leading to the inlet side of the pump. The passages leading to and from each bearing chamber are arranged on opposite sides of the bearing and are separated by a relatively-large circumferential distance. In a slightly-modified arrangement, the Bow of solution to each bearing chamber may be adjusted independently.

Title: Improvements in the manufacture of electric incandescent vacuum lamps
IPC: H01K1/56
Filed: 1923-08-09
Abstract: 221,625. General Electric Co., Ltd., and Campbell, N. R. Aug. 9, 1923. Residual gases; filaments. - In the final exhaustion of bulbs by the " gettering " process, described in Specification 187,055, [Class 39 (i), Electric lamps, Arc &c.], the residual gas has applied to it during the process a voltage much greater than that of the supply for which the lamp is designed, such voltage being not less than 50 and preferably more than 100 volts, to obtain in the lamp the requisite ionization for accelerating the " gettering " process, which ionization cannot be produced by the normal voltage of the lamp. The high voltage may be obtained by burning the filament in a circuit in which the mean volts are not much greater than the value for which the filament is designed but in which the peak value is much greater, the frequency being great enough to give a copious thermionic emission without great variation in the filament temperature during the alternations. Such a peaky voltage may be obtained by means of a mercury jet interruptor to which the peak potential is applied. An alternative method, specially applicable to very low voltage lamps, consists in supplying the filament b, Fig. 3, with its normal voltage from a source of supply s and during the final exhaustion by the " gettering " process, maintaining between the filament and a third electrode c within the lamp a sufficient voltage to ionize the contents of the lamp. The electrode c is kept positive with regard to some part of the filament and at the requisite potential by any suitable device v. The third electrode may consist in a wire c, Fig. 1, projecting into the vacuous space, or coiled around the stem in the case of a zig-zag filament lamp, and provided with a lead-in wire which is cut off after the lamp has been completely exhausted.

Title: Improvements in or relating to fuel-injection pumps
IPC: F02M59/26
Filed: 1939-07-22
Abstract: 532,398. Fuel injection pumps. BRADBURY, C. H., and RUSTON & HORNSBY, Ltd. July 22, 1939, No. 21306. [Class 102 (i)] In a fuel injection pump for multi-cylinder internal combustion engines in which the delivery stroke of each plunger 1 is effected positively as by means of a cam and the return stroke under the action of a spring 2, and in which regulation of the fuel supply is effected by partially rotating the plungers simultaneously by means of a common rack bar 20 connected to the engine governor and engaging toothed control sleeves 4, or pinions 10 on such sleeves, which are rotated with the plungers, each plunger is provided with a member, or one part of the sleeve, which is connected to the governor and normally rotated with the sleeve, or with the second part of the sleeve, so that the member, or one part of the sleeve, of a seized plunger can be partially rotated relative to the sleeve, or to the second part of the sleeve, so as to permit adjustment of the sleeves of the normally operating plungers. The enlarged upper end of each sleeve 4 may be divided transversely into two parts 4a, 4b the engaging surfaces 7 of which are helical or inclined circumferentially to form one or more teeth on each part, the shoulders 8 of which teeth are vertical or undercut. During normal operation, relative rotation of the two parts 4a, 4b, is prevented by means of a spring 9 or by means of serrations or fine V-shaped radial gripping teeth 21 on the two surfaces 7. The upper end surface 11 of the part 4a or the pinion thereon is separated by a small clearance from the end of a bore 12, whilst the shoulder 17 on the part 4b bears on a flanged collar 13 located in a recess 15 and receiving the end of the spring 2. Diametrically opposite lugs 18 on the plunger engage in longitudinal slots 19 in the part 4b. Should one plunger seize, a spring-controlled hand lever (not shown) moves the rack bar 20 producing a torque which first lifts the part 4a of the seized plunger to the top of the aforementioned clearance and then forces the part 4b downwards to permit the part 4a to be rotated relative to it so that adjustment of the normally operating plungers can be carried out simultaneously to cut off the fuel delivery and stop the engine. If the hand lever is not operated, the sleeve 4 comes automatically under the influence of the spring 2 so that the engine operates at a speed a little above normal.

[Also in Division G3] A machine tool 10 such as an end mill is controlled by means of a multi-channel magnetic tape, the information on which is produced from a drawing as disclosed in copending Specification 1,071,531, the instructions on the tape being extracted in the form of impulses by a tape reader 12 and the impulses being used to control stepping motors which control the movement of the cutting tool 160 in the X, Y and Z axes and which maintain the axis of the cutting tool always perpendicular to the surface of the workpiece W (Figs. 2, 3, not shown) being cut. Information is extracted from the tape by the tape reader 176 in the form of electrical pulses, which pulses are fed to a motion indicating display panel 186, the instruments in which panel indicate the travel, in terms of impulse steps, of the cutting tool in the X, Y and Z co-ordinates from a given origin. The panel 186 also contains instruments which indicate the angles α, #, # which the axis of the cutting tool makes with the X, Y and Z planes respectively. From the display panel 186 the impulses are fed to a plurality of stepping motors 62, 86, 104, 118, 130, 146. The workpiece is carried on a swinging bridge 42 mounted in trunnions about which it is swung by the motor 62. A beam 110 carrying a carriage 122 holding a cutting tool 160 is raised or lowered (the X axis), by the stepping motors 86 and moved towards or away from (the Z axis) the workpiece by stepping motors 104. The tool carriage 122 is moved end to end of the beam 110 (the Y axis) by stepping motors 130. In order to maintain the tip 162 of the tool 160 normal to the workpiece, the angle α which the tool axis makes with the horizontal or X plane is controlled by stepping motors 118 which cause the beam 110 to swing about its pivots whilst the angle # which the tool axis makes with the vertical or Y plane is controlled by stepping motors 146 which cause tool to move angularly in curved racks carried on the tool carriage 122. The angle γ which the tool axis makes with the Z plane is automatically determined by the settings of the angles α, #. A control desk 188 is provided by means of which the initial setting up of the machine and workpiece may be effected.

Title: Arrangement of soldered printed circuit board connections
IPC: H05K3/40
Filed: 1976-05-24
Abstract: 1501584 Printed circuit assemblies WESTINGHOUSE AIR BRAKE CO 24 May 1976 [27 May 1975] 21473/76 Heading H1R To avoid malfunction due to the introduction of spurious resistance from poor soldered joints in a printed circuit containing circuit elements connected thereto, there are provided first and second terminal pads interconnecting two circuit elements at least one of which has external lead wires. A first solder joint connects one such lead to a first terminal pad and a second solder joint connects the lead at another spaced point of its length to the second terminal pad, whereby resistance in the first joint is added only to the circuit path of the second circuit element and is excluded from the path of the first circuit element.  In an amplifier (Fig. 1) having a transistor Q with emitter resistor R E  and collector resistor R C  between points P 2 , P 3  defined by conductive pads of a printed circuit board, the gain is established by ratio RC/RE. The resistance  RX 2  of a poor solder joint between resistor R C  and pad P 1  connected to the collector is effective to increase gain by ratio RX 2 /RE to an output signal connection at P 1  while if the output is  taken from pad P 2  the resistance RX 2  is effectively added to the emitter resistor R E  and the gain is reduced to act in a fail safe direction. Contact resistance, e.g. RX 3  in the input to the next stage also reduces the signal.  In construction (Fig. 3) output to the following circuit is derived over a printed circuit from' pad P 2  while one lead of the circuit resistance element R C  is soldered to an aperture in pad P 2  and at a spaced distance to an aperture of a pad P 1 ; the other lead being soldered to apertures of pads P 3 , P 4  to which and from which B + supplies are connected over printed circuits.  Alternatively (Fig. 4) pads P 2 , P 3  are positioned spacedly on one side of a printed circuit board to register with pads P 1 , P 4 , on the other side with non-conductive through holes therebetween. The leads of the circuit resistance element R C  are taken through the apertures of the pads and the intervening holes and soldered;  the connections of the collector and subsequent stage, and of the B+ supplies being taken to pads P 1 , P 2 ; P 3 , P 4 , respectively.  In a twin T filter (Figs. 5, 6) the leads of resistor R 1  are respectively soldered to pads P 5 , P 6  and P 7 , P 8  at spaced positions while the input, capacitor C 1 , resistance R 2  and capacitor C 2  are respectively connected to pads P 6 , P 5 , P 7 , P 8  over printed circuits; so that high resistance in a solder joint at P 6  merely reduces the input signal rather than adds to the value of resistance R 1 , a high resistance at P 5  appears as impedance in the circuit path of C 1 , high resistance at P 7  reduces the signal at resistance R 2  and high resistance at P 8  appears in the circuit path of C 2 ; in which circuit paths improper operation will be in a direction affording safe operation.
