Title: Improvements in or relating to carriers or holders for cartridge fuses
IPC: H01H85/56
Filed: 1945-10-22
Abstract: 603,505. Fusible cut - outs. GENERAL ELECTRIC CO., Ltd., and BIGNELL, G. J. H. Oct. 22, 1945, No. 27743. [Class 38 (i)] A cartridge fuse carrier 1 has two clips which retain and make contact with the metal endcaps 3 of a cartridge fuse, each clip comprising a pair of opposite contact blades 5 having arcuate portions 7 fitting the end-cap and bowed portions 6 which together may enter the socket of a fuse base. Apertured extensions 9 of each blade pivot on the linked ends 13 of the arms of a V-shaped support 10 fixed to the fuse carrier. The arms 16 of a steel spring superimposed on the V-shaped support bear on the free ends of the extensions 9 so that when the blades engage an end-cap (Fig. 2) they are pressed into closer contact, and when the blades are rotated in their pivots away from an end cap they pass through a dead-centre to a stable position free of the end-cap, allowing the latter to be removed (Fig. 3). To increase the pressure of the blades upon an end-cap, the portions 6 which enter the socket of a fuse base, are bowed, and the free ends 17 are bent together forming a pivot point such that when the blades enter the socket the pressure between them and the fuse end-cap is increased.

Title: Improvements in or relating to a wood screw manufacturing process
Inventor: CHIABERTA SERAFINO
IPC: B21K1/44
Filed: 1949-10-29
Abstract: 668,577. Forging wood screws. GUEST, KEEN & NETTLEFOLDS (MIDLANDS), Ltd. Oct. 29, 1949, No. 27759/49. Addition to 652,163. Classes 83 (ii) and 83 (iv). The method of making wood screws from wire &c. blank by means of pairs of dies according to the parent Specification is modified by (a) using stock of oval or like flattened crosssection so as to eliminate the preliminary step of flattening the round stock by forging, or (b) flattening the round stock by a rolling-operation. As shown, a continuous rod 10 of round stock is first locally flattened at 12 by a pair of dies 11, a pair of dies 13 simultaneously forming partial threads on the flattened sides of a previously-formed flat portion 12. The dies 11, 13 are then retracted and dies 14 operating at right angles to the dies 11, 13 complete the thread and restore the round section, whilst severing dies 16 close on to the stock. Dies 11 and 13 are then operated again to remove the fins left by the dies 14, and a die 9 is actuated to produce a head in countersunk portions of the dies 13. The stock is fed forwardly step-bystep after each cycle of operations. The machine shown comprises a table 20 having horizontal extensions 21, 22 and a vertical extension 23. The dies 11, 13 are carried by slides 34 mounted on the extension 23 and actuated by levers 35 which are pivoted to the table at 36 and operated by cams 28 on a main drive-shaft 26. The forward stroke of the dies is adjusted by means of set-screws 37, the return stroke being effected by hooks 39 on the levers engaging lugs 40 on the slides. The severing-dies 16 are similarly carried by levers 42 which are actuated by cams 29 on the shaft 26. The vertically-movable dies 14 are provided with stems 52 adapted to slide in bearings 53 and are actuated by levers 56, 57 which are fitted with headed screws 60, 64 respectively engaging recessed heads 63 on the stems 52. The levers 56, 57 are pivoted at 58, 65 to the table and are connected by a link 66 having a slotted engagement with a lever 68 which is oscillated by a cam 32 on the shaft 26. The heading-die 9 is carried by a bar 69 adapted to slide in bearings 70, 71, one of which is of non-circular section, and is normally urged towards the work by a spring 73. A cam 33 on the shaft 26 engages a lug 75 on the bar 69 to retract the die until the cam clears the lug, when the spring 73 reacts to advance the die. To ensure complete detachment of the screw, after the dies 16 have operated, a cam 80 on the shaft 26 is arranged to engage the arm 79 of a spring-loaded cranked lever 78 to rock a strikerarm 76 against the finished screw. The timed forward feed of the stock is effected by a blade 91 obliquely mounted in a cradle 90 which is pivoted on a slide 86 carried at one end of a lever 93. The other end of the lever 93, constrained by a spring 95, is actuated by a crank 30 on the shaft 26.

Title: Locating method for electromagnetic radiation
IPC: G01S3/788
Filed: 1967-06-16
Abstract: 1333371 Opto-electronic ranging ELTRO GmbH & CO GES FUR STRAHLUNGSTECHNIK 16 June 1967 [30 June 1966] 28000/67 Heading H4D An arrangement for determining the distance and direction of an object in space emitting infra-red radiation comprises two spaced optical systems F1, W1, W3 and F2, W2, W4 situated at opposite ends of a base line and forming object images in planes Z1, Z2, these images being respectively modulated by modulation systems M1, M2 to produce electrical output signals S1, S 2  from detectors P1, P2. Each modulation system comprises, Fig. 2, a disc 21 with radial slots 22, the two discs being rotated by a motor M0 in the direction of arrow 24 and also being similarly rotated about an optical axis 25 as indicated by arrow 26. Due to parallax, an object situated at a finite distance from the optical systems produces an image displaced from the centre of the discs and due to the rotation and nutation of the latter this image is displaced laterally and the slots cause a frequency modulation over a corresponding frequency range, the two signals S1 and S2 being  mutually displaced through 180 degrees and having the same frequency sweep. For an object situated at infinity the parallax is zero. Thus the distance of the object is a function of the frequency sweep and may be computed from the signals S1 S2. The direction of the object is determined by comparing the phase of the signals S1, S2 with a reference phase signal R derived from the motor M0. The computing is done by electronic data processing means (Fig. 4, not shown) in which three signals A, B and E are produced, of which A and B represent the values for the abscissa and ordinate of the object, related to a right-angled system of coordinates associated with the object and in a plane parallel to the base line, and E represents the distance between the base line centre point and the said plane so that the distance of the object is determined by E<SP>1</SP> = #A<SP>2</SP>+B<SP>2</SP>+E<SP>2</SP>.

Title: Improved manufacture of alkali cyanides
IPC: C01C3/00
Filed: 1925-11-07
Abstract: 265,305. Coulier, S. Nov. 7, 1925. Materials and composition for making gas and other products. - Animal and vegetable substances comparatively rich in nitrogen are heated with alkalies or alkaline compounds so as to produce a carbonaceous residue containing nitrogen together with combustible gas and other products. The raw materials include animal waste, molasses and liquors from sugar works and distilleries, residues from the treatment of hides, leather or the like, sewage water and sludge, and waste waters and sludges from wool washing. When the raw materials contain sulphur, a sulphur-binding agent is added such as alkaline earth oxides or carbonates, iron, manganese, or their oxides, particular mention being made of calcium carbonate formed in the carbonation of limed sugar solution. When the raw material is acid, such as vinasses from molasses, the sulphur-binding agent may be used for neutralizing them. To ensure a suitable ratio between alkali and carbon in the solid residue of distillation, either carbonaceous material such as peat, or alkalies may be added to the raw material. In one example, leather or tannery refuse is heated with sodium carbonate at 350-450‹ C. preferably under reduced pressure. In another example, slaughterhouse offals are digested in strong caustic soda or potash in an autoclave and the pulp is distilled first at 200-220‹ C. for extracting glycerine, and then up to 300-400‹ C., the vapours being condensed for the recovery of more glycerine ammoniacal compounds and oils. In another example, vinasses from sugar-beet is concentrated with an addition of carbon, sawdust, damaged pulp, or other carbonaceous matter, and iron or iron oxide, and heated in a retort to 300-500‹ C. under ordinary or moderate pressure. The distillation products are combustible gas, a condensate containing ammonia and amino-compounds, oils, and tar. In another example, vinasses mixed with lime is distilled in a closed vessel at moderate pressure at temperatures gradually rising to 300-400‹ C. Ammonia, amines, acetic acid, methyl alcohol, light oils and tars are recovered in the usual way.

Abstract: 1,115,333. Electric selective signalling. LICENTIA PATENT-VERWALTUNGS, G.m.b.H. 2 July, 1965 [3 July, 1964], No. 28090/65. Heading G4H. [Also in Division H2] The sum or difference of two frequencies each represented as a multi-phase system of electric pulses is obtained by calculating operations using logic elements. Pairs of pulse trains with frequencies proportional to the actual and desired speeds of a squirrel-cage motor, and a phase difference between the two trains of each pair indicating the direction of rotation, are passed to AND/OR logic to produce a pair of pulse trains at the sum or difference frequency. The theory involves approximating the pulse trains as sinusoids and applying well-known trigonometrical addition theorems. During the calculation, pairs of pulses are produced to represent ternary digits and converted to binary using storage elements. Instead of " two-phase " (i.e. two trains) inputs and output as above, threephase may be used. The input frequency from the motor is multiplied, and the output frequency divided, before use.

Abstract: 520,991. Treating gases with liquids. BURGESS, S. (Fansteel Metallurgical Corporation). Nov. 1, 1938, No. 28225/39. Divided out of 520,839 under which a Specification was laid open to inspection under Sect. 91 of the Acts, May 16, 1939. [Class 55 (ii)] [Also in Group III] Exothermic reactions between liquids and gases, such as the absorption of hydrogen chloride in water are effected by passing the gas and liquid in co-current down a straight passage or tube with heat-conducting walls, and passing a cooling liquid in counter-current on the outer side of the walls. Contact between gas and liquid before they enter the cooled passage is avoided. In the illustrated apparatus the liquid entering at 18 passes through a seal 22 and overflows the serrated top of tube 14 which has lateral ribs 66 to assist the spreading of the liquid film. The tube is preferably made of tantalum or niobium or alloys thereof. The liquid reaction product is withdrawn from the bottom of the tube by pipe 48. The gas enters at 10 and passes down the interior of the tube; unreacted gas is withdrawn through the central, pipe 38 which opens at a point 40 some distance below the bottom of the tube 14. The cooling liquid is admitted at any desired points by valves 32 into the jacket 26, and leaves at the upper end 21. The portion of the tube below' the gas exit 40 has a separate jacket 45. The unreacted gas leaving the apparatus may be used in a counter-current chamber scrubber 54 to effect a partial saturation of the liquid before it enters the principal apparatus. A modification (not shown) is described for dealing with gases of low concentration, in which a small proportion of rich gas is admitted to the bottom of the tube and passes upwards to the exit 40 thus concentrating the product during its flow down. the lower section of the tube.
