Title: Improvements in or relating to the manufacture of transistors, rectifiers and other semi-conductor devices
Inventor: FELL ROBERT ANDREW
IPC: H01L21/00
Filed: 1958-06-18
Abstract: 869,863. Semi-conductor devices. FELL Ltd., A & M. June 10, 1959 [June 18, 1958], No. 19462/58. Class 37. In a method of alloying activator material to a semiconductor during the manufacture of a rectifier diode or transistor a pellet of the material is located in contact with the semi-conductor by a real or synthetic jewel jig. In one embodiment (Fig. 3) a pellet 1 of indium is placed in the cavity formed by the annular and flat jewels 4b, 4a beneath a germanium wafer 6, and a second indium pellet 8 dropped into the aperture of a third jewel 8. The jewels, which may consist of ruby, sapphire, spinel, zircon, or rutile are located in steel shanks 5, 7 by spinning the bevelled edges of the shanks over the corresponding bevelled edges of jewels 4b, 8. The annular and flat jewels 4b, 4a may be replaced by a single jewel with a hemispherical or conical cavity in its upper face. Alloying is effected by passing the assembly through an oven. As an alternative a single pellet is first alloyed to the upper face of the wafer in an assembly in which the lower jewel or jewels are replaced by a plane surfaced jewel, whereupon the wafer is inverted and a second pellet alloyed to the now uppermost face. The advantage of using jewels for the jigs is that they can be machined with greater precision than other refractory materials.

Title: Modulating system and method for humidification of enclosures
IPC: B05B15/52
Filed: 1958-06-19
Abstract: 854,676. Humidifiers. PARKS-CRAMER CO. June 19,1958 [June 24,1957], No. 19628/58. Class 55 (2). [Also in Group XXIX] As shown, a humidifying system for an enclosure comprises a water vaporizing unit 6 of the atomizer type, a conduit 20 supplying water, a conduit 10 through which air at superatmospheric pressure passes, a valve 58 in water conduit 20 and means 12, for example a humidistat, a thermostat or a humidistat and a thermostat in conjunction, by which valve 58 may be controlled, and means 64 on the outlet side of valve 58 by which the rate of discharge of water through unit 6 may be regulated in response to variations in the rate of flow through valve 58 so as to establish equilibrium between unit 6 and valve 58, and to compensate, independently of means 12, for irregularities in the water-discharging capacity of vaporizing unit 6. Compressed air enters at 10 and whenever humidity as measured by humidity 12 falls below a predetermined value valves 18 and 72 open and the air passes by lines 19 and 4 to atomizing unit 6. Some compressed air also passes from valve 72 to water valve 58 to control the rate of flow of water through line 20 from tank 8, in which the level 22 of water is maintained some inches below the outlet level of atomizing unit 6 by means of ball-cock 28. Between valve 58 and atomizing unit 6 there is a pocket 64 in the water line (there may also be a second pocket 77, if desired) which is preferably vented to the atmosphere at 66. When the system is put into operation pipes 20, 64, 2, and 54 will fill with water to the level 22 and air will pass through valves 18 and 72, and spray will emerge from atomizers 6 which are of the self-cleaning type (see Group XXIX). As the humidity approaches the predetermined value, air pressure in line 60 decreases and restricts the flow of water through valve 58, so that, as the volume rate at which the water passes through the valve 58 drops below that issuing from atomizers 6, the level of water in line 74 drops from A to some other level B. This increases the lift required to raise the water to the nozzles and so, with a constant air pressure delivered to the atomizers, the amount of spray is reduced. The Specification describes other pockets 64 in the water lines which may be used, all being of the same principle. U.S.A. Specifications 2,434,421, 2,623,782 and French Specification 587,315 are referred to.

Filed: 1921-07-22
Abstract: 187,702. Landsiedel, H. July 22, 1921. Hammer-impression arrangements. - In recording-apparatus for adding-machines, the type-carriers that are moved to a recording position permit the associated hammer-latches to be moved by springs into engagement with a latch-releasing device, and the type-carriers in returning to the normal position co-operate with the springs in restoring the latches; the latches may be provided with couplings for effecting the printing of zeros and for splitting the machine. In the preferred arrangement, shown in Figs. 1, 4 and 9, hammers 8, pivoted on a rod 9 and connected to actuating-springs 13, are held in the retracted position by longitudinally-movable latches 15 having noses 16 engaging the tails 12 of the hammers. The latches are guided by combs 11, 19 and are connected to springs 17 which hold the latches in the rear position and tend to rock them upwards about a pivot-rod 21, such rocking movement being normally prevented by projections 20 on the type-carriers 1. The latches are formed also with lugs 38 co-operating with a releasing-device 31 consisting of a laterally-movable bar pivoted at one end and connected at the other end to a lever 33 controlled by a cam 36. On rocking forwards a cam-shaft 3, the selected type-carriers move to recording position, the projections 20 thereon moving away from the associated latches, and the bar 31 then moves to the right, permitting those latches to rise and engage the bar by means of the projections 38. On returning the cam-shaft, the bar 31 moves the engaging latches to the left and effects release of the associated hammers. The hammers are returned by means of a bail 40 controlled by a cam 45, the projections 20 and springs 17 co-operating to restore the latches. For effecting the printing of zeros and splitting the machine, each latch, excepting that at the extreme left, is provided with a coupling-piece 25, Fig. 9, engaging a lug 22 on the adjacent latch at the right, the coupling- piece being carried by a resilient lever 22 which can be rocked by a finger 29 to render ineffective the coupling. The lever is retained by a projec tion 26 engaging recesses 27, 28.
