Abstract: 359,492. Casting type &c. BROWN, J., 2, Queen Street, Eastwood, Nottinghamshire. July 23, 1930, No. 22150. [Class 100 (iii).] A device for casting type, furniture, quads, &c. comprises a casting-box in which a matrix of flong &c. is obtained from type or other patterns, and type are then cast from the matrix. The casting- box 1, Fig. 2, has a detachable baseplate 2, and contains a pair of bars 4, between which the type patterns 6, Fig. 3, are positioned. One or both bars 4 may be adjustable by means of screws 5. The type patterns are separated by gauges. 7, which may have lugs engaging recesses 4a, 4b, or may engage in vertical slots in the bars. A sheet 8 of flong &c. is placed between the bars 4 and the baseplate 8, and is indented by pressure applied by clamping-screws 3, which connect the baseplate to a transverse metal-injecting gate. 9. The type patterns are then removed, and molten metal is poured through the gate 9, so as to form duplicates of the type. A type-bar bearing a number of letters or words may be used instead of separate type patterns. Hollow furniture, quads, &c. may be cast by means of cores 10, Fig. 5, which are clamped between the bars 4. A number of pairs of bars may be employed to enable several lines of type to be cast at once. The lugs formed on the type by the recesses 4a, 4b are removed after the casting.

Title: Process for the preparation of lithium aluminium hydride and lithium gallium hydride
IPC: C01B6/24
Filed: 1952-09-04
Abstract: Lithium aluminium hydride is prepared by reacting a solution of aluminium bromide in an anhydrous solvent with a suspension of lithium hydride in an anhydrous liquid which is the same as the solvent or miscible therewith.  Ether or tetrahydrofuran are suitable.  The lithium hydride need not be crushed and may be of peanut to hazelnut size and suspended by agitation.  The suspension, e.g. in ether, is heated to boiling, under reflux, and the solution, also in ether, added dropwise with agitation.  On cooling and filtering an ethereal solution of lithium aluminium hydride saturated with lithium bromide is obtained, which may be used as such for hydrogenation after which the spent solution, freed from lithium bromide, may be reused for lithium aluminium hydride production. Alternatively, lithium bromide may be removed from the ethereal solution and the lithium aluminium hydride separated as a solid. Lithium gallium hydride may be similarly prepared.

As applied to a vehicle 4, Fig.1, a series chain of temperature responsive resistors 10, 11, 3 measure the temperature of the outside air, engine cooling air and vehicle interior; a variable resistor 2 sets the desired interior temperature; and the electronic switch controls vacuum motor 8 via a throttle 12. The motor 8 controls a member 13 which (a) regulates the heat supply, and (b) a feedback resistor 7. The chain may form one branch 14, Fig.3, of a bridge circuit 14, 19, 20, 21, having across its balancing diagonal, a transistor circuit 22-27, measuring the difference between resistor 14 and a fixed resistor 19 to actuate, if this difference exceeds a pre-set value, either relay 17 or 18 via relay 28 or 29 according to the sign of the error. Relays 18, 19 control electromagnetic valves to progressively adjust the pressure applied to the vacuum motor 8. The relays may be replaced by transistors, and the chain of resistors replaced by a single NTC resistor measuring the vehicle interior temperature.

Title: Improvements in and relating to process for the recovery of nicotine from tobacco material
IPC: C07D401/04
Filed: 1933-08-15
Abstract: <PICT:0423606/IV/1> Nicotine is recovered from tobacco material by applying indirect heat to the material, which has previously been fermented or treated with alkali and damped, and using the aqueous vapours thus generated to drive off nicotine from more of the same material, the nicotine being finally extracted from the aqueous vapours by a finely subdivided solution of acid which reacts exothermically and so maintains the temperature of the vapours. Specifications 11460/10 and 327,034, [both in Class 2 (iii)], are referred to. The tobacco material, previously treated with milk of lime, is supplied through rotary gate 10<1> and conveyer 11 to the inclined rotary drum A whence it falls into the box I, and is fed into the rotary dryer E to be ultimately discharged at the conveyer 23.  Steam is supplied through pipes 21 and 22 in drum E for heating the material and the steam generated passes through conduit H into the drum A, in which the pressure is slightly reduced by a suction fan C, and volatilizes and sweeps away the nicotine from the material in drum A to the bottom of the tower 35, which contains a packing through which sulphuric acid of about 0,6N flows, absorbing the nicotine and passing out to the tank 43.  The remaining hot aqueous vapours are subjected to a second extraction, the acid being re-circulated.  The nicotine is obtained as a salt.  Instead of sulphuric acid, hydrochloric or acetic acids may be used for the absorption.

Title: Magnetic core memories

Filed: 1971-04-19
Abstract: 1336238 Magnetic storage arrangements HONEYWELL INFORMATION SYSTEMS Inc 19 April 1971 [29 April 1970] 22972/71 Heading H3B [Also in Division G4] A magnetic core matrix has some of its cores so oriented relative to the matrix drive lines that their magnetic states cannot be switched. The matrix shown in Fig. 1 contains conventionally oriented ring cores 11, which can be switched by coincident row and column pulses, and cores 24, 26, 28, 30 which are oriented so that the switching flux due to coincident pulses is along their axes and switching cannot occur. During reacting, these latter cores always indicate the same binary bit. The sense wire 22-22<SP>1</SP> threads the cores in a symmetrical pattern to minimize noise. Noise cancellation is complete for the rows, but the orientation of the non-switchable cores prevents complete cancellation of column half current noise. To minimize this latter effect, the column pulses are initiated prior to the row pulses, the sense winding being strobed after initiation of each row pulse. An inhibit wire 20-20<SP>1</SP> is used, either in that part 12 of the matrix containing only switchable cores, or over the whole matrix as in Fig. 2 (not shown). The latter arangement allows cores 26-30 to be kept fully saturated. A multi-plane arrangement may be used.

A knotting bill 19, operated by a trigger 14, is journalled in a frame 10 having forwardly extending sides 21, 22. A plate 23 is secured to side 21 but is spaced therefrom by a member 24. A plate 27 is secured to side 22 in contact therewith, and has an inwardly extending arm 28 from which a guide wire 29 depends. Plates 23 and 27 are formed respectively with forwardly facing slots 25 and 30. Sides 21 and 22 are formed respectively with rearwardly facing slots 26 and 31. A thread 39, when drawn into slots 25 and 30, is guided by wire 29 to engage the knotting bill in front of the point of the latter. A thread 38, when drawn into slots 26 and 31, moves behind the point of the knotting bill, and, since the latter slots extend below and in front of slots 25 and 30, the threads thereby cross one other at each side of the bill. A plate 35, pivoted on a hollow stay 32 separating the frame sides, is formed with a notch which, when the bill is rotated to tie a weaver's knot, moves the threads into engagement with the scissors of the knotting bill.

Also mounted on the pivot 7 below the gramophone motor board is a ghost arm 4 which extends parallel to, and moves about pivot 7 with, the pick up arm 3. The free end of the ghost arm carries a pair of photo-cells 2a, 2b one on each side of line S1 passing vertically through stylus S, and a light source 01 at the turntable centre directs light past shutter member 5 to the photo-cells. The cells are equally illuminated when there is no tracking error i.e. when a horizontal line connecting the pivot axis P1 of the pick up arm and ghost arm and the vertical line S1 through the stylus is at right angles to a radius line through line S1. Any movement from this condition is detected by a differential output from the cells which controls rotation of arm 6 to reduce the error to zero.
