Title: Improvements in or relating to cap-firing toy guns
IPC: F41A15/00
Filed: 1965-08-12
Abstract: 1,113,866. Toy guns. G. FERRI and J. MARINAI. 12 Aug., 1965 [21 Aug., 1964], No. 34485/65. Heading A6S. A cap firing toy pistol has means for simultaneously firing and ejecting a spent cartridge. The caps are supported on a notched strip 6, Fig. 4 (not shown), and are fired by a forward and spring controlled release movement of the barrel 10, Fig. 1, under the control of a trigger lever 19. Forward movement of the barrel 10 also causes a lever 22 to be moved clockwise, as viewed in Fig. 1, to move the cap supporting @surip upwards to bring the next cap into firing position. At a certain forward position of the barrel the tooth at the top of the trigger lever slips from a tooth 10g on the barrel 10 which thereupon snaps back to the original position under the influence of a leaf spring 16. A firing pin 14a, Fig. 14 (not shown), mounted in the rear end of the barrel thereupon fires the newly placed cap, and a cutting 14c associated with the firing pin sheers the previously fired cap from the strip which thus becomes ejected from an aperture 8, Fig. 4 (not shown).

Title: Improvements in apparatus for transmitting television and the like
IPC: H04N3/04
Filed: 1937-12-13
Abstract: 507,428. Television. GENERAL ELECTRIC CO., Ltd., and ESPLEY, D. C. Dec. 13, 1937, Nos. 34492/37 and 28983/38. Divided out of 507,667. [Class 40 (iii)] A moving picture F or Nipkow scanning disc or its image Fl, Fu is so moved backwards relatively between successive interlacing scans that the holes which make one of the interlacing scans also make the scans with which it is interlaced. The two images of the picture (or disc) are formed by a fixed optical system Pu, Pl, which provides two optical paths associated with a source of light S. A shutter interrupts the paths alternately. The two paths are caused to deviate by two prisms Pu, Pl with their edges adjacent and the distance apart of the images is adjusted by mirrors Mu, Ml. According to modifications the adjustment is by two sets of four mirrors, Fig. 6 (not shown), or by two pairs of prisms, Fig. 7 (not shown), or by an hexagonal glass body, Fig. 8a (not shown), which may be split in two halves, Fig. 8b (not shown), or by two inclined blocks of glass, Fig. 9 (not shown). Instead of using a shutter, the source of light may be alternately associated with the paths. For this purpose images Su, Sl of the source of light are formed alternately by means of semicircular mirrors Mu, Ml, which are rotated at a sub-multiple of the speed of the scanning disc. Alternatively, semicircular glass plates are used, Fig. 11 (not shown). An additional lens between the film F and a lens L2 may so produce an intermediate image of the film between intermediate images Su1, Sl1 of the source and the lens L2 that the final image of the source lies between the lens L2 and the images Fu, Fl of the film, and the means for adjusting the relative displacement of those images may be transferred to the region between the lens L2 and the final image of the source. Specifications 455,972, 463,863, 475,032, 482,049, 494,365, 498,625, and 507,667 are referred to.

Abstract: 605.365. Delivery stopping arrangements for spinning &c. machines. PRINCESMITH & STELLS, Ltd., and FEATHER, E. E. Dec. 20, 1945, No. 34556. [Class 120(ii)] An electrically-controlled stop-motion for spinning and like textile machines has a pivoted, biassed, circuit-closing detector supported by a thread and, associated with the circuit, an electromagnetically controlled roving trap, consisting of a polished cylindrical fixed abutment opposite to which a blade carried by the armature of the electromagnet is disposed, the detector being adapted to close the circuit when the thread breaks so that the roving is held by the trap in the rear of the feed rollers. The invention is described as applicable to centrifugal spinning and like machines; such machines, according to the Provisional Specification, are disclosed in Specifications 529,307, 529,308, and 529,309. Roving R from a package 11 passes beneath the abutment 27, against which it is pressed by the blade 28 when the circuit to the electromagnet 24 is closed. From the abutment the roving extends through the drawing head to the detector 14 which has a bifurcated tail 16 normally held from contacts 17 by the pressure of the spun thread as it passes into a holder 5. Thread breakage allows the detector 14 to tilt back, closing the circuit and causing the finger 28 to trap the roving R, which is broken by the cbntinued rotation of the drawing rollers.

Class 85 Well drilling aparatus comprising a drill bit with flushing fluid nozzles, a motor for rotating said bit, and a tubular drill string, wherein the connection between the bit and the drill string includes a ram device comprising two hollow telescopic members for controlling the weight on the bit when the conditions under which the bit is advancing vary. The motor may be at the top of the borehole or it may be adjacent the bit when the drill string is kept stationary or rotated very slowly. In one embodiment, Fig. 1, the outer telescopic member 3 of the ram is secured to the bottom of the drill string 1 and the inner member 4 carries the bit 2. The two members 3, 4 are splined together at 5 to allow relative axial movement only. The outer member 3 has abutments 8 defining separate cylinders and the inner member 4 has pistons 6 dividing each cylinder into upper and lower cylinder spaces 7. The spaces 7 above the pistons 6 are subject via passages 11 to the pressure of the drilling mud passing down the drill string to nozzles 10 in the bit 2 while the cylinder spaces 7 below the pistons 6 are subject, via passages, 12 to the pressure of the drilling mud in the borehole, the pressure difference between the upper and lower spaces 7 acting downwards on the bit. The bit may have relief valves to limit the pressure difference across the nozzles 10. In another embodiment. Fig 9B, the motor is a hydraulic turbine driven by the drilling mud and is placed adjacent the bit, a shaft 21 from the turbine driving a gear pump 22<SP>1</SP> which supplies drilling mud or a separate servo fluid under pressure through a pipe 24 and passages 25 to the spaces 7 above the pistons 6, the fluid passing through venting orifices in the pistons to the spaces 7 below the pistons from where it returns to the pump through passages 12<SP>1</SP> and a pipe 24<SP>1</SP>. One or more of the pistons 6 may be put out of action to reduce the weight on the bit by connecting the spaces 7 above and below the piston either together or to equal pressure sources. This can be performed manually by removing, replacing or adjusting screwthreaded plugs in the abutments 8 or in the walls of the members 3, and 4 or performed automatically by spring-loaded valves which render a piston 6 inoperate when the pressure difference above and below it exceeds a predetermined value or when the rate of circulation of the drilling mud exceeds a predetermined value. In this way the pistons, which may have different surface areas, may be put out of action one at a time, and the weight on the bit, together with the speed of the turbine (if used), can be controlled by the pressure or the rate of circulation ,of the drilling mud in the drill string.

Abstract: In the catalytic treatment with hydrogenating gases of carbonaceous materials, the catalyst is mounted upon a non-metallic carrier into which an acid substance has been incorporated in an amount not exceeding 10 gram equivalents of acid per kilogram of carrier.  The amount of acid should preferably be sufficient to neutralize most or all of the basic substances present in the carrier.  Carriers to which the invention may be applied are brown coal, coke, lignite coke, peat, bauxite, Florida earth, alumina, bentonite, diatomaceous earth, active silica, brick, burnt fireclay, and magnesite.  Suitable acids are sulphuric, hydrochloric, and nitric.  They may be applied in presence of a wetting agent.  According to an example, lignite coke is activated with steam at 900 DEG  C., impregnated with ammonium molybdate solution, and then sprayed with sulphuric acid in amount sufficient to neutralize its basic impurities.  The product is finely ground and added to a mineral oil residue boiling above 325 DEG  C. which is hydrogenated at 470 DEG  C.  The product is subjected to a second hydrogenation using a tungsten sulphide catalyst giving a product containing 75 per cent of benzine and middle oil.
