Abstract: 662,170. Dynamo-electric machines. LUCAS, Ltd., J. Feb. 24, 1950 [March 3, 1949], No. 5812/49. Class 35. A machine for pegging or keying armature windings comprises the combination of a stationary annular headstock a into which the armature can be inserted, a plurality of fingers b corresponding to the number of slots in the armature and radially slidable in the headstock, means for simultaneously feeding the pegging material c into the headstock at positions in line with the fingers, and finger-actuating means whereby lengths of the pegging material can be severed and transferred to the armature slots. The headstock a has an axial boss d on which is mounted a slidable collar e having holes through which the material c can be fed. Spring-loaded grippers f on the collar e cause the material c to be fed to the inner end of the fingers b when the collar is advanced. Each finger b has a rack h engaged by a pinion i and all the pinions engage through intermediate pinions i<SP>1</SP> with a gear-wheel which is moved through an appropriate angle by a lever m actuated by a cam n, such movement causing the fingers to grip the pegging material while the collar e is being retracted. Thereafter, fluid or compressed air means o acting on arms f attached to the gear-wheel impart further angular movement to the wheel j and cause the fingers to sever the pegging material, and squeeze the severed portions beneath the shoulders adjacent the slot entrances. The collar e is actuated by a spring-loaded lever q and a cam p and a cam r actuates a valve s associated with the fluid-operated mechanisms o. A spring- loaded control lever t controlled by a cam w automatically releases the clutch u of driving mechanism v at the end of each cycle of operation. The pegging material may be made of paper shaped to a cord of circular section.

Patent GB-1208570-A (GB)
Title: Fuel injection systems for internal combustion engines
Inventor: MAIR JOSEPH
IPC: F02D41/30
Filed: 1967-02-07
Abstract: 1,208,570. Fuel injection control system for I.C. engines. ASSOCIATED ENG. Ltd. Feb. 1, 1968 [Feb. 7, 1967], No.5878/67. Heading G1N. [Also in Division H3] In known fuel injection control systems (e.g. Specifications 1, 038, 541 and 1, 107, 989) for I.C. engines, wherein a pulse generator including a mono-stable multi-vibrator energizes electromagnetic injector valves to open the valve for a period depending on the duration of each pulse, the higher the supply voltage the more rapidly the injector valve will open, the reduction in opening time increasing the length of the open period; likewise a lower than normal supply voltage reduces the open period and quantity of fuel injected. In the present Specification the injection period is made independent of the supply voltage by the application of a bias voltage to the mono-stable multi-vibrator which bias varies as the supply voltage varies, to lengthen or shorten the period. Compensating for supply volts variation. As shown, a bias voltage V 6  applied to the emitters of TR 1  and TR 2  of the multi-vibrator is derived from a potential divider P which includes a non linear element Z 1 , e.g. a Zener diode or saturated diode. Since the voltage across Z 1  remains practically constant as its current increases (or decreases) with changes in the supply voltage, the voltage across the resistors of the potential divider including the bias voltage Vb, across Rb, will increase in proportion faster than the supply voltage V s  . The voltage change across C1 which in part determines the pulse width is thus increased at a lesser rate than V s  so that the width of the pulse energizing the valves is reduced to compensate for the shorter opening time at the increased supply voltage. Likewise the bias Vb decreases proportionally with decrease in V s . In the circuit shown the control voltage V 1  is derived from for example, engine speed, acceleration and/or inlet manifold pressure and the control voltage V 2  which affects the discharge of C 1  through TR 4  is derived from engine temperature, air temperature, starting and idling enrichment signals for example, as in Specification 1, 107, 989.

Title: Continuous growth process
IPC: C30B11/00
Filed: 1964-02-13
Abstract: In the downward pulling of a crystalline rod through a die from a melt, a convex solidifying surface is maintained by employing a die of thermally anisotropic material, the thermal conductivity of the die in a direction perpendicular to the axis of the rod being at least 10 times that in the direction of the axis of the rod.  The thermally anisotropic material may be pyrographite or boron nitride. An n-type thermoelectric rod of an alloy of bismuth selenide and telluride containing iodine may be pulled. The height of the centre of the convex surface above its periphery is not greater than one thirtieth of the diameter of the rod.  The temperature gradient in the vicinity of the solid-liquid interface may be in the range of 500-1,000 DEG C./in.  The rate of pulling may be 1 in/hr. according to Fig. 1 (not shown), a rod 11 with a convex solidifying surface 50 is pulled through a die 21 from a melt 15 in a quartz vessel 13 #f which has a gas inlet 20 for argon and is heated by a resistance coil 17.  Die 21 has an annular recess 51 to assist in the control of the flow of heat, and is supported by an annular metal plate which is cooled by coil 27.  In a modification (not shown), the metal plate extends below the die to increase the temperature gradient in the vicinity of the solid-liquid interface.  The rod is quenched by passage through oil and a cooling coil 43.  According to Fig. 4 (not shown), a rod 11 is pulled from each of four orifices 150 in a die 121 which has outer and inner annular recesses 151a and 151b respectively.

Title: Improvements in or relating to vehicle hydro-pneumatic suspension units
Inventor: DICKINSON RONALD SIDNEY
IPC: B60G17/04
Filed: 1957-02-23
Abstract: 870,554. Hydro-pneumatic springs; regulating road vehicle height. ARMSTRONG PATENTS CO. Ltd. Feb. 13, ]958 [Feb. 23, 1957; Nov. 21, 1957; Jan. 7, 1958], Nos. 6154/57, 36245/57, and 562/58. Classes 108(2) and 108(3). A hydro-pneumatic spring comprises a casing B (Figs. 1, 2 of the third Provisional Specification) rigid with the vehicle frame and a piston (not shown) connected by a link E, crank K, and shaft S to a road wheel (not shown). A diaphragm D separates oil from air under pressure. Oil is forced into a space C between the piston and diaphragm D by the action of a pump plunger 1 engaged by a cam L carried by the shaft S. This has the effect of raising the vehicle to a predetermined height, a spindle 3a, then lifting a valve 10 to permit escape of oil from the space C via a channel 14a to a reservoir R. In a modification (Figs. 1-5 of the first Provisional Specification, not shown), the valve 10 is in a separate housing from the pump and has an operating member actuated from a further plunger and a respective further cam on the shaft S. In the modification shown in Fig. 2 of the second Provisional Specification the reservoir R is augmented by an external reservoir (not shown). Oil is drawn from the external reservoir during pumping strokes via an inlet valve G. When the valve 10 is lifted oil is returned to the reservoir R as before but excess oil in the latter is forced back to the external reservoir via a valve H. One external reservoir may supply a plurality of suspension units (Fig. 3, of the second Provisional Specification, not shown). The pump plunger 3 embodies a filter element 7 which also acts as a flow restriction. Specification 867,500 also is referred to.
