Title: Logical circuit building block
IPC: H03K3/037
Filed: 1970-09-17
Abstract: 1283623 Transistor logic circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 17 Sept 1970 [20 Sept 1969] 44503/70 Heading H3T To provide a logic-performing circuit on for example an integrated circuit L with more input signals than there are input terminals I 1 , I 2  at least one input terminal goes both directly to LE and also through a gate 10 or 20 and store S 10 , S 20  to LE so that successive inputs at that terminal I 1  or I 2  are presented in parallel to LE. The stores are bi-stables and the gates are controlled by a control signal Co whose inverse at OO, or a further signal C<SP>1</SP>, may be used to initiate operation of the logic circuit LE when all required inputs are present. A gate may be included also in the direct lines (11, 21, Fig. 3, not shown) and controlled by C 0 , further bi-stables (S 11 , S 21 ) also being included if desired. If two input terminals receive complementary inputs (I 1  and I 1 <SP>1</SP>, Fig. 2, not shown), these may be supplied directly to LE to form one pair of complementary inputs, and through respective gates (10, 101) controlled by C 0  and a common bi-stable (S 1 ) to form another pair of complementary inputs; or alternatively the direct connections may be modified to also include respective gates controlled by C 0  and a common bi-stable. More detailed constructions of these two complementary-input circuits are described (Figs. 8, 9, not shown) using NAND gates, the Fig. 8 circuit performing an exclusive-or function on inputs a, a and subsequently received inputs b, b. In further refinements of these circuits, a two-phase clock (C 0 , C 1 , Fig. 10, not shown) replaces the control signal C 0  and a J-K flipflop is formed as the storage circuit (N 1  to N 8 ), and also (Fig. 11, not shown), a reduction in the number of NAND gates used is obtained. In one embodiment (Fig. 4, not shown) each input has two gates and two stores as well as a direct connection to LE so that three successive inputs may be presented in parallel. In a more elaborate embodiment (Fig. 12, not shown) using the above circuits, various unspecified logic functions are first predetermined by a set of conditioning inputs (A 0  to A 5 ) and these functions then performed on further inputs (B 1 , B 2  &c.).

Abstract: 1,036,675. Milling. GIDDINGS & LEWIS MACHINE TOOL CO. Nov. 4, 1964 [Dec. 11, 1963], No. 44897/64. Headings B3B and B3K. [Also in Division F2] The spindle 23, Fig. 1 (not shown), of a multiple axis type contour milling machine is mounted on a bearing assembly (see Division F2) arranged to be preloaded to a maximum or a minimum value dependent on the spindle speed selected. The machine comprises a fixed base 15 on which is mounted a longitudinal slidable base 16 having mounted thereon a swivel base 17 movable in an arcuate path over the sliding base 16. A column 18 is rigidly connected to the swivel base 17 and serves as a support for a vertically slidable saddle 19 having mounted thereon a swivel saddle 20 movable in an arcuate path in a vertical plane. The swivel saddle 20 supports a headstock 21 in which is mounted the spindle 23 coupled through a planetary gear reduction unit 24 to a variable speed electric motor 22. The selection of a particular spindle speed by operation of the gear reduction unit, determines which of two solenoid operated control valves is energized and consequently whether the bearing assembly is preloaded to a maximum or a minimum value.

Abstract: 453,032. Actuation of switches. SCINTILLA AKT.-GES., Solothurn, Switzerland. Oct. 24, 1935, No. 29374. Convention date, Oct. 25, 1934. [Class 38 (v)] In a reversing switch operated by change of direction of rotation of a dynamo shaft, pawls 23, 24, 25, 26 situated between flanges on the shaft engage levers 8, 9 pivoted at 7 on a disc fixed to the moving contact - carrying disc, driving the latter into its alternative position at each change of direction of rotation, the pawls and levers being all disposed in the same plane. The levers 8, 9 are acted upon by a spring 10 which presses their ends 30, 29 against a segment 2 provided at its ends with recesses 3, 4. The narrow ends of the pawls are the heavier and gravity brings them to the position shown excepting the pawl 23 which is driving the lever 9 round in a counterclockwise direction. When the end 29 drops into the recess 4, this movement aided by gravity acting on the pawl 23, disengages the pawl, so that the contact member stops in its new position while the shaft gives on rotating. At high speeds, centrifugal action keeps all the pawls out of contact with the levers 8, 9. When the shaft reverses, a pawl 24 or 26 engages the lever 8 driving it to the left till its end 30 drops into the recess 3.

In the embodiment shown, the used rinsing fluid flows into chamber 40 and is pumped from the chamber to header tank 90 which feeds a cuvette wash trough 42, a tube incubator tank 68 and a sampling head probe wash tank 106. When the tube rinsing system is operating, the used rinsing fluid from drain conduit 60 fed via pump 86, header tank 90, standpipe 92 and tank 80, serves to maintain the level of the incubation bath in incubator tank 68. When the tube rinsing system is not operating, the incubation bath is fed with a trickle of fluid from source 12 via flow control means 70, 72, line 76 and tank 80.

Abstract: 1,059,775. Moderator structures. UNITED, POWER CO. Ltd. Nov. 1, 1965 [Nov. 13, 1964], No. 46380/64. Heading G6C. A solid moderator core structure comprises a plurality of closely-spaced, adjacent columns of vertically aligned prismatic blocks arranged so that laterally adjacent blocks present, in juxtaposition, parallel faces formed with oppositely disposed keyways which accommodate a composite key assembly consisting of vertically spaced " solid " keys to locate laterally adjacent blocks with respect to each other, and " split " keys to occupy the intermediate portions of the keyways between the " solid " keys and to space and support the " solid " keys in position and to minimize voidage in the core structure In one embodiment (Figs. 1 and 2, not shown), a " solid " key 3 projects from the top face of an existing layer of blocks and additional blocks 1a, 1b are assembled in such a way that the " solid " key 3 fits into both the keyways 2a, 2b on the opposed faces of the blocks. A " split " key made up of two spacer portions 4 is then lowered into the keyways until it rests on the " solid " key 3. Each portion 4 enters one keyway only, and the length of each portion 4 is sufficiently smaller than the length of the blocks for a further " solid " key 3 to fit into the keyways 2a, 2b with its lower end resting on the " split " key and its upper end projecting above the top surfaces of the blocks 1a 1b. This key 3 can then be used to locate a further layer of blocks. In Fig. 3B (not shown), the results of differential Wigner strain of the blocks are illustrated, the blocks 1a 1d in one column having been strained into a curved formation whereas the corresponding blocks 1b la in an adjacent column are undistorted. The " solid " keys 3 are not in shear and remain vertically aligned. The portions 4 of the " split " keys remain in the keyways in the corresponding blocks and are deformed with the latter. In an alternative embodiment (Fig. 6, not shown), the " solid " keys 3 are located within the length of the blocks, vertical alignment being obtained by means of the " split " key portions 4. Spacing blocks may be provided if the choice of prismatic block so demands, for example, where the blocks are of octagonal cross-section, and these may also be designed to co-operate with the keying system.

Title: Method of making silicon carbide fibres
Inventor: PULTZ WALLACE WILLIAM
IPC: C01B31/36
Filed: 1966-10-18
Abstract: Silicon carbide fibres are prepared by heating carbon and silica in an atmosphere containing certain halide gases.  Carbon and silica, in a motor ratio between 1:1 and 5:1 are heated to 1300-1550 DEG  C. in a furnace, in an atmosphere containing one or more of the gases hydrogen fluoride, hydrogen chloride, hydrogen bromide or silicon tetrachloride and optionally a gas inert to the reactants.  The total partial pressure of the halide gas is between 25 and 350 mm. of mercury and the pressure may be made up to atmospheric by using hydrogen. The reaction vessel is preferably evacuated to less than 1 mm. of mercury before the halides are introduced.  Heating is continued for between 1/2 and 24 hours until the desired fibre growth is achieved and the reaction vessel is then cooled, preferably first to about 400 DEG  C. when air is admitted and then to room temperature. Fibres produced by this process have a diameter of 1-2 microns and lengths up to 5 cm.  They have a core of b -silicon carbide and a surface sheath of silica.
