Patent GB-297060-A (GB)
IPC: D01F2/04
Filed: 1928-09-13
Abstract: 297,060. Linkmeyer, C. R. Sept. 13, 1927, [Convention date]. Ammoniacal-copper cellulose solutions, processes and apparatus for making filaments from. -The water used as precipitant in the spinning of artificial silk threads from cuprammonium solutions of cellulose by the stretch-spinning process is treated in order to reduoe its air content below that normally present in water at the temperature and degree of vacuum prevailing in the spinning funnel. Thus, for example, water containing about 14¢ cubic centimetres of air per litre under these conditions is de-aerated until it contains only about 10 cubic centimetres per litre and is therefore no longer capable of giving off air during the spinning process, with the result that the prejudicial effect of dissolved air upon thespinning process is avoided. In the apparatus shown, the water flows by syphon action to the spinning funnel i by way of pipe e, container c, pipe f, reservoir g and tube h and whilst passing through the container c is subjected to partial vacuum, for example about 1¢ metres of water, which is greater than that employed in the spinning funnel. This partial vacuum is produced in the container a which is connected with the container c by pipe b. The water is at the same time heated above the spinning temperature by heat tranference through the ribbed tubular bodies d. The used precipitant liquid may be passed through a heat exchanger in order to cool the heated water passing from the container c to the spinning funnel i.

Title: Improvements in apparatus for delivering weighed portions of material to a packing machine
Inventor: SHARMAN CHARLES FREDERICK
IPC: B65B1/32
Filed: 1948-10-14
Abstract: 647,818. Webbing-apparatus. IMPERIAL TOBACCO CO. (OF GREAT BRITAIN & IRELAND), Ltd. Oct. 14, 1948, No. 26717. Addition to 620,433. [Class 143] [Also in Group XL(b)] In weighing machines as claimed in parent Specification which are provided with scale emptying means so controllable as to allow for the differing loading times of various operators and so arranged that each scale pan can be emptied only when a receptacle is located below it, the emptying means is operated by an electric circuit controlled partly by a photo-cell illuminated according to the position of the scale and partly by a switch actuated in accordance with the movement of the receptacles. As shown, tobacco, for example, is fed by the operator on to a scale pan 22, attached to beam 20 pivoted at 21. An arm 40 attached to the beam carries a slotted member 41 through which light passes to a photo-cell 62 when the scale is in the balance position. The photo-cell response is amplified by a triode 68 to operate an anode relay 69, the contacts of which are then held closed by a spring-loaded lever 79. The operator then closes hand-switch 56. When a receptacle 10 is beneath the pan a cam 61 rotating in synchronism with the receptacle movement closes contacts 54 completing the circuit to a pan emptying solenoid 47. The plunger of this solenoid pivots a lever 34 against the action of an oil-dashpot 49 and causes pivoted levers 28, 29 to come against pins 31, 32 so as to rotate to the dotted position the scale pan separating into two halves 26, 27 and the tobacco falling into the receptacle. Lever 79 ensures that as tobacco leaves the pan photo-cell operated contacts 52 do not immediately open, closing the scale pan, since this lever is held in engagement with armature of relay 69 throughout the weighing period. To prevent two separate weighings being deposited in one receptacle a solenoid 71 is energized in series with pan emptying solenoid 47, and its plunger depresses one of a number of pins 74 carried on a constantly rotating disc 73 end pin corresponding to a particular receptacle. The pins normally hold contacts 55 in series with the pan emptying solenoid closed but when a pin corresponding to a full pan arrives the switch opens, and so more material can be deposited in that pan. The pins are reset by a fixed cam 79. Disc 73 may be dispensed with and cam 61 may be so arranged as to operate only for certain of the receptacles.

Title: Micro programme data processor having parallel instruction flow streams for plural level of subinstruction sets
IPC: G06F9/22
Filed: 1973-06-05
Abstract: 1426749 Microprogrammed data processor BURROUGHS CORP 5 June 1973 26717/73 Heading G4A Each micro-instruction comprises one or more syllables and includes at least an operator syllable which is used to access a corresponding control instruction in a control memory (e.g. read-only store), and the fetch of each control instruction occurs concurrently with the fetch of the microinstruction syllable which follows next after the corresponding operator syllable. As described, for each microinstruction, there is overlap between incrementation of a micromemory address register and accessing of the microinstruction memory so that a microinstruction is addressed while the address of the next microinstruction is being generated; between addressing of the microinstruction memory and fetching the preceding microinstruction from memory; and between fetching a microinstruction and fetching a control instruction for the previous microinstruction. Micro-instructions have a variable number of syllables, the first containing an operator which is used to address the control memory, and each control word defines the combination of general purpose registers to be used with an arithmetic and logic unit and the function to be performed. Overlap between microinstruction fetch and execution employs a push down stack for microinstruction addresses, and timing of a microinstruction fetch operation is dependent on the current machine state and the type of the current and next microinstructions. The processor is identical to that described in Specification 1,426,748.

Filed: 1929-09-04
Abstract: 318,625. Kruckenberg, F., and Stedefeld, C. Sept. 8, 1928, [Convention date]. Tracks having a single guiding rail; tracks having two guiding and bearing rails with supplementary rails; rails, metallic built-up.-Comprises a high-speed railway system in which the - running wheels of the vehicle serve solely to carry the load, guidance being effected by a guide rail engaged between at least two pairs of lateral rollers, and propulsion is effected by a third member, preferably a propeller, separate from the carrying and guiding wheels. In the construction shown in Fig. 1, the vehicle is propelled by a screw propeller 13, plain wheels 11 run on rails 10, and guide rollers 17 engage both sides of a rail 14 carried on a support 15. The rollers are carried by arms swinging on longitudinal pivots 19 and are pulled towards each other by a spring 20. In a modification, the guide rollers are carried by arms swinging on vertical pivots. Derailment is prevented by a hinged link 21 which prevents the rollers from separating sufficiently for flanges 18 on their lower sides to move clear of the guide rail. Lateral movement between the rollers and the vehicle body is transmitted by laminated springs 22 connected at their ends by links to the body. The guide rail may be formed in two parts 25, 26, Fig. 4, secured together by bolts so as to break joint. The support 15 for the guide rail is constructed so as to be somewhat resilient to lateral shocks. Derailment may be prevented by providing the running wheels with flanges 31, Fig. 5, which normally do not touch the running rails, and the guide rail may be used as an emergency support in conjunction with shoes or rollers 30 mounted on the running wheel axles above the guide rail.

Title: Driving device for tuning units
IPC: H03J1/14
Filed: 1965-06-25
Abstract: 1,088,945. Tuning adjustment. R. HOPT. June 25, 1965 [July 25, 1964], No. 26993/65. Heading H3Q. [Also in Division F2] A tuning arrangement comprises a rotatable drum carrying adjusting screws 19 which selectively engage a member 24 to alter the tuning, and a cam 18 with the same number of sections as the number of adjusting screws to lift the member 24 away from the screws while the drum is being rotated by knob 31. The screws have flats 20 on their upper parts so that they can slide non-rotatably in the bottom plate of the cam, and pass through threaded gearwheels 21 for axial adjustment. The appropriate gear 21 meshes with a gear 48 on a shaft 47 driven from a subsidiary knob 43 via gears 44- 46. The shaft 47 is journalled in elongated holes in the tuner casing and the gears 21 and 48 are normally kept in engagement by springs 49. As the drum is rotated, the shaft 47 is forced outward until the next gear 21 comes into position. Backlash between the gears is prevented by springs 22 which force the bottom ends of the screws towards one another. The pin 24 rests on the top ends of the screws except when lifted up by the cam, and is attached to an arm 25 pivoted at 25<SP>1</SP> (Fig. 2, not shown) and bearing a toothed sector which engages a gear 26 on the tuner shaft. A cord 29 wrapped round this shaft at 30 is spring-loaded at 28 to urge the pin 24 downwards against the adjusting screws. The drum is located in each position by a spring-loaded roller 33 bearing on notches in the plate. To ensure that the cam can only be rotated in one direction these notches have sides which are unsymmetrical about a radius of the plate (Fig. 3, not shown). An auxiliary switch 59 for range-changing or voltage switching is operated by an arm 58 which engages a pin 56 that can be inserted in one of several holes 57; the pin and holes are repeated for each position of the drum. Modifications.-The springs 22 can be replaced by a leaf spring 23 (Fig. 3, not shown) mounted on the underside of the plate 16 and urging the screws 19 outwards. The shaft 47 can be driven by a separate knob (Fig. 5, not shown), the shaft being pushed in against a spring to effect engagement of the gears 21 and 48. The shaft is not then movable radially. The cam profile can be symmetrical, in which case the notches engaging the roller 33 may permit rotation in either direction.

Abstract: 1329918 Handling radio-active material COMMISSARIAT A' L'ENERGIE ATOMIQUE 19 April 1971 [20 April 1970] 26993/71 Heading B4Q [Also in Division H1] Apparatus for the analysis of radio-active samples in a predetermined atmosphere comprises a vertical charger formed by a lead flask 4 and a pile of support plates for samples, the pile being vertically movable within a bore in the flask 4, a first horizontal passage 8 which extends through the charger and couples the bore to a vertically movable disc 14, a second horizontal passage 10 displaced both angularly and vertically with respect to the passage 8 and which extends between the movable disc 14 and a detector 12 housed within a shield 120 for measuring the radio-activity of the samples, and a slide 34, 64 in each passage for transferring a sample and capable of translational motion within the respective passage, the external walls of the lead flask 4, the passages 8, 10 and the detector 12 defining a single sealed enclosure in communication with conduits for controlling the atmosphere within the enclosure. The samples are thus placed in the atmosphere necessary for measurement from the time of introduction into the lead flask 4 and contamination of this atmosphere, e.g. during transfer of the samples, is therefore not possible. By virtue of the vertical and angular positional displacements of the passages 8, 10, the radiation emitted by the samples contained in the lead flask 4 is not transmitted to the detector 12, the detector being influenced solely by the sample which is placed within the passage 10. The sequence of different operations, viz. downward motion of the support plates, horizontal displacement of the slides 34, 64, and upward and downward motion of the disc 14 whithin a channel 9 connecting the passages 8, 10 is effected automatically by means of electric contacts which are placed at the end points of the different movements. Manual analysis of a predetermined sample can be made by introducing the sample directly into the passage 10 and for this purpose an auxiliary orifice is provided in the wall of the passage 10 with a plug 80, the interior of which forms a lock chamber, closing the orifice.
