Abstract: 1,021,158. Rolling. DETROIT TAP & TOOL CO. Nov. 13, 1963 [March 5, 1963], No. 44906/63. Heading B3M. A tool holder suitable for thread forming rollers, comprises spaced arm portions, each housing a pin on which is mounted a roller, and adjusting means for moving the pins towards and away from each other. Knurling, embossing, or burnishing rolls may be used. Between plates 40 and 42 (Fig. 2, not shown) of a tool holder 10 are housed freely rotatable thread rollers 30 and 32, a spacer block between the plates having curved recesses 54 and 56 suitable for housing rollers of varying sizes. The mounting pin 34 of roller 30 is housed in bushings 60 each of which can be turned through 180 degrees to give a second position of the roller 30 relative to a workpiece W. Screws 86 and 87 co-operate with flats on the pin 34 to hold it securely. The pin 36 of roller 32 is housed in slots 96 and 98 of the plates 42 and 40 and is continuously adjustable in the slots by screws 108, 110, 112 and 114. The rollers are positively geared together by means of gears 150, 152 and 154 which are housed in recesses in the plate 42. Limited relative movement between the gears 120 and 122 and their respective pins is possible since the hubs of each gear are provided with radial lugs which can move circumferentially in correspoding slots (Fig. 6, not shown). Strips 142, however, bias the gears into engagement with the roller hubs during thread rolling.

Filed: 1970-09-25
Abstract: 1328571 Elevated railways J M JACOBS Jnr and N S STAFFORD 25 Sept 1970 [29 Sept 1969] 45915/70 Heading B7L A transportation system comprises a load carrier 20 (Figs. 3, 4) having at least two pairs of upper spaced apart guide wheels 33, 35, two pairs of lower spaced apart guide wheels 37, 39 and two support wheels 38, which are preferably driven by electric motors 96, the carrier moving in use along a guide beam 30 in cantilever fashion as shown in Fig. 3, and having hooks 81 (Fig. 4) thereon for supporting a load thereon, a switch section (Fig. 12) being provided for connecting a first guide beam 130 with either of two spaced guide beams 131, 132, the switching of a load carrier being effected by providing for axial movement of the support wheels 38 relative to the load carrier body by mechanism shown in Fig. 9 to direct the wheels 38 on to running surfaces appropriate to either the guide beam 131 or 132. The beam 30 in Fig. 3 is shaped to accomodate a load carrier on both sides thereof and Figs. 12a to 12i show sections through the track at corresponding section lines a-a to i-i of the switch depicted in Fig. 12. Thus, Fig. 12a, shows a section through the guide beam 130 and Fig. 12i through the two guide beams 131, 132 spaced vertically one above the other. As a local carrier enters the switch along guide beam 130 its support wheels run along horizontal surface 143. From Figs. 12b and 12c it is seen that the surface 143 widens to form a surface 146 and a further guide surface 150 is provided for the upper guide wheels 33 of the load carrier. If it is desired for the carrier to pass to the guide beam 131 then its support wheels are moved axially by operation of an hydraulic cylinder 105 (Fig. 9) acting through bell cranks 107, the drive to the wheels from gear housings 70 being maintained by splines 69. In this way the wheels 38 are moved to run on the surface 146 and as this surface separates from the surface 143 and rises (Figs. 12d and 12e) the load carrier is raised, the surface 150 maintaining its position on the track until the guide wheels 35 contact surface 148 (Figs. 12f and 12g) and the guide surfaces for each guide beam separate from each other (Fig. 12h). Arrangements are also described in the Specification using principles similar to those described above for switching between horizontally aligned guide beams and between upper and lower parallel guide beams. In a further embodiment of the invention the support wheels 38 run along a horizontal surface adjacent the upper guide wheels 33, 35 and the guide beams are modified accordingly.

Title: Field sustained conductivity devices
IPC: H01J29/10
Filed: 1965-11-05
Abstract: A memory device exhibiting conductivity which is modified by an incident radiation or electron beam to a valve which is sustained at least temporarily on cessation of the beam unless the applied voltage is removed or reversed consists of an insulating support carrying a cadmium sulphide layer sandwiched between an aluminium electrode and another electrode. A barrier layer between the aluminium and the adjacent sulphide layer has been formed by heating them in a sulphur containing atmosphere. A typical device is made by vapour depositing aluminium to a thickness of 5000 <\>rA on a prepared glass substrate, vapour depositing a 0.5 m  thick layer of cadmium sulphide over it and then heating, preferably at 300 DEG  C. for 2 hours in a flow of dry hydrogen sulphide or sulphur dioxide.  An electrode layer of aluminium, platinum, tin oxide, gold, indium, palladium or rhodium is then deposited on the layer. The resulting device exhibits a rectifying characteristic which varies in accordance with the duration and temperature of the heat treatment, the reverse conductivity displaying the memory feature.  In an alternative arrangement the positions of the two electrode layers are reversed and the heating repeated after deposition of the aluminium to provide the barrier layer. A device similar to this, used as a target in a direct viewing cathode-ray tube storage device, comprises a gold or tin oxide layer on the face plate of the tube carrying in the following order an electroluminescent layer of cadmium or zinc sulphide activated with manganese or chlorine, the cadmium sulphide and a layer of aluminium.  Optical feedback from the electroluminescent to the cadmium sulphide layer may be prevented by an interposed layer of chromium sulphide.  The tube includes a conventional electron gun and scanning arrangements. Information contained in the modulated electron beam is stored as a conductivity pattern in the reverse biased target to provide a field pattern across the electroluminescent layer which manifests itself as a pattern of light and shade.

Abstract: 1,089,098. Semi-conductor devices. MOTOROLA Inc. Nov. 16, 1965 [Dec. 14, 1964], No. 48625/65. Heading H1K. A method of forming isolated regions embedded in a substrate comprises masking a semiconductor starting wafer 10, epitaxially depositing a region 14 of semi-conductor material, applying a layer 30 of insulating material, and a substrate 32 over the region and the surrounding surface of the wafer and then removing the starting wafer, Figs. 2A to 2D. The starting wafer 10 may be removed by etching and the substrate 32 may be flattened by etching or polishing. Transistors are formed by selective diffusion into the deposited regions 14. The masking layer may be silicon dioxide which is treated by heating in HC1 vapour to prevent deposition of semi-conductor material on it during the subsequent process. Insulating layer 30 may also be of silicon dioxide and substrate 32 may be polycrystalline silicon deposited by reduction of SiHCl 3 . The top layer of the deposited epitaxial region may be heavily doped so that in the final structure a conductive layer underlies the isolated region to reduce the collector series resistance of the transistor, Figs. 3A and 3B (not shown). Two regions of opposite conductivity types may be produced by epitaxially depositing a region of one type and covering with a layer of silicon dioxide, Fig. 4A (not shown), etching a new window, epitaxially depositing a region of the opposite type, covering with an oxide layer and depositing a polycrystalline substrate, Fig. 4B (not shown), and then removing the starting wafer, Fig. 4C (not shown). PNP and NPN transistors are formed in the two regions by appropriate diffusions Fig. 5 (not shown). During the epitaxial deposition of the silicon, HBr or HCI may be introduced into the gas stream to control the profile of the deposited regions. The epitaxial regions may be doped by adding the hydrides or halides of phosphorus, arsenic, antimony or boron to the gas stream. Apparatus suitable for the deposition of the various layers on a plurality of wafers is illustrated diagrammatically in Fig. 1 (not shown).
