Title: Multi-way programme branching circuits
IPC: G06F9/00
Filed: 1974-08-06
Abstract: 1475136 Data processing systems XEROX CORP 6 Aug 1974 [6 Aug 1973] 34564/74 Heading G4A A processor includes multi-way branching means comprising a number of addressable units which store portions of memory addresses. The units are addressed and the output of one of them selected under program control to force a branch to a new address when required. The processor may include a microprogram memory. The embodiment discloses a processor including an arithmetic logic unit controlled by microprogram instructions from a control memory. A microprogram instruction may, for example, consist of a 60-bit word including a 16-bit address field. The address field, Fig. 3, passes to a unit which generates the address of the next microprogram instruction. This next address is either determined directly from the address field or forced to a branch address dictated by a main instruction from an I register. As indicated in Fig. 3, the next address includes the FD and FC fields of the current microinstruction and two bits whose source is determined by the FB and FA fields. When a branch address is to be forced the FC field of the current instruction, together with an 8-bit signal from the I register, selects a 4-bit signal from one of the addressable units and this signal is placed in bit positions 5-8 of the next address, instead of the FC field. As shown in Fig. 4 there are 16 addressable units, each being a programmable read-only memory containing 256 4-bit words. One such word from each memory is selected by the 8-bit signal from the I register and one of these is selected by the FC field as indicated.

Abstract: 1,068,428. Winding webs. MASCHINENFABRIK GOEBEL G.m.b.H. Aug. 13, 1965 [Aug. 14, 1964], No. 34778/65. Heading B6B. A plurality of webs longitudinally slit from a single web 1 are alternatively wound by a pair of identical turret winders. Each winder comprises a pair of spaced apart discs 4, 5, Fig. 2 (not shown) having a plurality of driven rollers 6 mounted therein, as shown in Fig. 1. Associated with each roller 6 is a plurality of pairs of spaced apart arms 11 keyed to a rocker shaft 10 also mounted in the discs 6. Each pair of arms 11 receives a sleeve 35 from a hopper as the discs are indexed and at the web transfer station urges a sleeve against a roller 6 with a web interposed therebetween. A pair of rods 18 and 19 mounted to slide longitudinally in the discs 4, 5 under the action of a pair of cams 20, 21 fixed to the machine frame, are provided with tappets 22 and 23 respectively, Fig. 2 (not shown), which engage respectively the left and the right hand arms 11 of each pair. Depending on the indexed position of the discs 4, 5, each pair of arms 11 is urged inwardly at the sleeve pick-up station, the web transfer station and the winding station to grip the sleeve or web-roll, and at the remainder of the stations are moved apart to release a completed webroll on to a ramp 34, and to hold the arms apart in readiness, for the next sleeve. Each rocker shaft 10 has a lever 13 and a cam-follower roller 14, Figs. 2 and 3 (not shown) which associate with a cam 12 fixed to the machine frame. Depending on the indexed position of the discs, the arms are allowed to hold the sleeves or web-rolls against the rollers 6 at the web-transfer station and winding station, and are positioned away from the rollers 6 at the other stations. The width of the key slot 37, Fig. 3 (not shown) for each arm 11 is greater than the width of the key 36 in the rocker shaft 10, and this allows the arms 11 free movement when biased by the springs 15, thereby accommodating the increase in diameter of the webroll as it is being wound. When the web-roll 29 has attained its final diameter at the winding station, ascertained by a scanning device or yardage counter (not illustrated), a nozzle 31 sprays adhesive on to the webs, followed an instant later by a knife 33 severing the webs between the winding station and the transfer station. The trailing web edges are adhered to the outer turns of the web-rolls and the leading edges are adhered to the new sleeves. The discs 4, 5 are then indexed through 60 degrees, whereby the completed web-rolls are lowered on to the ramp 34, the new-web rolls continue to be wound at the winding station, and the new sleeves having been transferred from the hopper to the arms 11 are held in readiness in contact with the interposed webs and roller 6 at the transfer station.

Title: Pressure gauge
IPC: G01L9/00
Filed: 1964-08-26
Abstract: 1,065,192. Semi-conductor strain gauges. ROSEMOUNT ENGINEERING CO. Aug. 26, 1964 [Sept. 3, 1963], No. 35010/64. Heading H1K. [Also in Division G1] A transducer for use in a pressure gauge (see Division G1) consists of a semi-conductor body, e.g. of silicon, to which pressure is applied to cause a change in the resistance of a portion of the body. The body is cup-shaped with a longitudinal bar attached to the closed end defining an annular cavity between the bar and the wall. The wall is made very thin except near the open end, across which is sealed, or rests, a glass disc. The annular cavity is evacuated. Two pairs of nickel, gold or rhodium contacts are deposited on the inside or outside of the wall after removal by etching or abrading of portions of an oxide coating formed on the body before fusing the glass disc thereto. The contacts of one pair are spaced longitudinally and those of the other pair circumferentially. The active regions of the wall, between the contacts of each pair, may be doped by exposure of the body to phosphorus pentoxide vapour and etching away the doped regions not required. The assembly is again coated with oxide prior to bonding the glass disc thereto and the oxide is then removed at the points where contacts are required. Nickel contacts are deposited by an electroless process and sintered in place. If the transducer is to be used at high temperatures (Fig. 11), the oxide layer is then removed from a strip 139 adjacent the contacts and nickel is deposited in these regions. The strips adhere to contacts 130, 131, 132, but can be lifted at their other ends to form connecting leads 140, 141, 142. For normal temperature use leads are soft soldered to the nickel contacts. The resistance between the contacts may be increased by providing a doped path in a zig-zag configuration. As shown in Fig. 11, a second glass disc 136 may be attached to the closed end of the transducer, the disc having platinum-rhodium strips 137 fused into it for securing the transducer within the housing of the pressure gauge. An embodiment is also described in which the first glass disc rests on the open end of the device and the central bar is slightly shorter than the walls so that the device responds to axial pressure on the glass plate, transmitted by a steel plate carried by a diaphragm. Reference has been directed by the Comptroller to Specification 961,852.
