Title: Improvements in the manufacture of fused silica
IPC: C03B5/033
Filed: 1927-12-23
Abstract: 283,148. Quartz et Silice. Jan. 5, 1927. [Convention date]. Drawings to Specification. Fused silica.-Relates to the method of producing fused silica, in which sand is packed around a carbon rod that is raised to a high temperature by the passage of an electric current. According to the invention, an oxidizing atmosphere is maintained in the furnace during the melting period in order to obtain a finished product which does not contain either free carbon or silica. Air or oxygen may be circulated through the furnace, but the desired result is preferably obtained by adding a regulated quantity of water to the sand before it is introduced into the furnace.

Title: Data Processing Device Incorporating a Counter
IPC: G06F9/32
Filed: 1967-08-01
Abstract: 1,173,934. Data processing. INTERNATIONAL BUSINESS MACHINES CORP. 1 Aug., 1967 [12 Sept., 1966], No. 35211/67. Heading G4A. A data processing device comprises a sequence control counter in which counting bi-stables have respective steering bi-stables, and capable of skipping selected steps in the sequence. Figs. 6, 8 show a binary counter having counting bi-stables 11, 13, 15, 17 and steering bistables 19, 21, 23, 25, driven by set and upset lines 37, 39 respectively which are pulsed alternately and by a reset line 35 pulses on which accompany corresponding set pulses at 37 but are shorter. In the bi-stables, the full-line blocks are inverters, one or more horizontal lines feeding a common vertical line represent the AND function, and one or more vertical lines feeding a common horizontal line represent the OR function. Like-labelled lines are connected. Thus each bi-stable has a latch-back path, each counting bi-stable 11, 13, 15, 17 is controlled by the corresponding steering bistable 19, 21, 23, 25 and each steering bi-stable is controlled by the corresponding counting bistable and the previous steering bi-stable (if any). and the previous counting bi-stable (if any), except that 21 is not controlled by 19. The counter controls (from the counting bistables) execution of a computer instruction, gating at the inputs to the steering bi-stables (including that gating in Fig. 6) causing the counter to skip selected counting states according as the instruction specifies its operands by direct, indirect or immediate addressing, and also causing the counter to skip from its highest count to its lowest. This gating is controlled by the bits of the instruction operation code N 1 , N 2 , N 3 , the state I A , I B , I C , I D  of the counting bi-stables decoded to 1-out-of-10 form I 1 -I 10 , and further timing pulses occurring between the set and upset pulses. The bi-stables shown may be replaced by magnetic or capacitor storage elements.

Abstract: 996,601. Transistor invertor circuits. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. Sept. 29, 1961, No. 35261/61. Heading H3T. An invertor for producing alternating current from direct current comprises a pair of transistors 1, 2 having the collectors connected to the primary windings of transformers T1, T2. The circuit is made self-oscillatory by positive feedback from secondary windings 7, 8 of T2 to the bases of the transistors and the frequency is stabilized by a pair of Zener diodes 13, 14 connected across one of the windings of transformer T2. As described, the core of transformer T2 should have a rectangular hysteresis loop. The frequency is adjustable by variable resistor 15. A diode 10a and resistor 10b facilitate starting. The frequency stability can be further improved by connecting to terminals 16, 17 the circuit shown in Fig. 2. The primary current in T2 is now controlled by transistor 19 which is itself controlled by the voltage from Zener diode 21 adjustable by variable resistor 20.

Abstract: 1,268,968. Trimming cans. REYNOLDS METALS CO. 15 July, 1969 [17 July, 1968], No. 35666/69. Heading B3W. Cans 26 to be trimmed are supported in cradles 42 on a rotatable head 40 and rotated above their axes while being moved by the head along an arcuate path near the arcuate cutting edge 46 of a fixed sickle blade 45. Each can is mounted on a holder 43, Fig. 17, which is aligned with a back-up device 50 on the head 40 which enters the can body and carries a blade 52 which is radially outwardly displaceable to co-operate with the blade 45 to trim an annulus 32 from the can, Fig. 5. Each holder 43 includes a vacuum cup 104, for engaging the can base 30, mounted on a rotatable shaft 101. Each back-up device is telescopic and is moved axially to enter a can by engagement of rollers 55 on the device with a cam plate 53 on the machine frame. Engagement of a stop 141 on the device 50 with an annular stop 140 on the main rotary shaft 35 on which the head 41 is mounted limits axial movement of the device. The blade 52 is a disc rotatable in a holder (207), Fig. 14 (not shown), which is slidable transversely of the device. In operation, cans are fed to position A of the head 41 by a screw conveyer 80 and a star wheel 76 positively geared to the main shaft 35. A guide 160 supports the cans as they are moved by the star wheel 41. As a can strikes the edge 235 of a guide 161A vacuum is applied to the vacuum cup 104 of its holder 43 and air is blown through the associated back-up device which is in its retracted position. At position B the can is still being rotated and the back-up device 50 has been advanced until the stop 141 has engaged the stop 140. Between positions B and C the can is rotated against the arcuate cutting edge 46 while continued axial movement of the device 50, through a bellcrank (215), Fig. 14 (not shown), displaces the blade radially outwardly to co-operate with the edge 46. Trimming continues to a point between positions C and D. By position D the device 50 is being retracted and the supply of vacuum to cup 104 and of blower air to the device have been cut off. The can falls into a shoot 60 and is removed while the device 50 is retracted through a fixed stripper ring 144 which knocks the annular waste 32 into a shoot (not shown). An air jet (134), Fig. 19 (not shown), may assist waste removal.
