Title: Improvements in or relating to target apparatus
IPC: F41J7/00
Filed: 1938-07-02
Abstract: 500,698. Target carriers. POLLAK, J. E. (Knudsen, P.) July 2, 1938, No. 19666. [Class 20 (i)] A target carrier comprises a magazine for supporting a series of targets and a slotted frame into which the targets slide in succession after successive actuations of an escapement disposed at the mouth of the magazine. The frame consists of slotted upright tubular members 1 connected together at their upper and lower ends by transverse members, upper and lower gaps being provided into which may pass the ends 11, 12 of upper and lower target support members 6, 10 respectively. The target supports are retained in an inclined magazine 4 by their upper bars bearing against an escapement 7 carried by a rock-shaft 6. As the escapement is rotated clockwise, the first target support enters the gap 9 while the succeeding targets are held back by the portion 8 of the escapement. The shaft is then rocked in the opposite direction, whereupon the first target is fed to the slotted frame and drops therein, the ends of the lower bar of the target support being of sufficient width not to be caught by the retaining spring catch 22 disposed in one frame upright. This catch, however, catches the upper cross-bar of the target support and holds the target in firing position. The rock-shaft is actuated from the firing position.

Abstract: 1,149,522. Colour television cameras. ELECTRIC & MUSICAL INDUSTRIES Ltd. 4 May, 1966 [11 May, 1965], No. 19764/65. Heading H4F. A colour television camera includes a case of which at least a part is of rectangular crosssection, light splitting means 8 for dividing an incident light beam into at least three light beams of different spectral composition, each of the latter light beams diverging from the axis of the incident beam toward the vicinity of respective longitudinal edges of the case part, and pick-up tubes 2, 5, 6 and 7 disposed to receive the light beams with their axis at least approximately co-linear with the beams. As illustrated the light splitter 8 provides four divergent beams one for a luminance tube 3 and the others for red, green and blue tubes 6, 7 and 2. These latter three beams diverge at 45 degrees to the horizontal axis, whilst the luminance beam diverges at 37 degrees. The beams also diverge rearwardly and make angles of more than 45 degrees and specifically no less than 60 degrees to the axis of the incident beam. Projections 5 may be provided to accommodate the ends of the lower two tubes, the projections also providing convenient mounts for carrying handles, Fig. 2 (not shown). One projection may be extended to provide a housing for the entry of the camera cable. A view-finder 9 is provided at the top of the camera between tubes 6 and 7. The front of the camera carries a zoom lens assembly. Each camera tube is surrounded by a double layer of magnetic screening material with an air space between to eliminate the differential effect of the earth's magnetic field as the camera dierction is changed. The beam splitter, Figs. 3-7 (not shown), comprises an assembly of prisms separated by various air gaps and having dichoic and reflective coatings on the surfaces.

Abstract: 1,212,228. Polyisoprene. PHILLIPS PETROLEUM CO. 26 April, 1968 [28 April, 1967], No. 19998/68. Heading C3P. Isoprene is polymerized in the presence of an initiator comprising a mono-bromo-phenyl-. lithium and 1,3-dibromobenzene as a viscosity modifier. The initiator may be 3- or 4-bromophenyl lithium. The modifier, which is used in an amount from 0.1 to 10 moles per mole of initiator, is preferably added after initiation and before 70% conversion. The initiator may be used in an amount sufficient to provide 0À05-50 gram milliequivalents of lithium per 100 gms. of monomer. The polymerization may take place in a liquid hydrocarbon solvent, at - 100‹ to +150‹ C. and in the presence of tetra vinyl or tetra allyl tin, the tin compound being used in amounts of from 0.025 to 1.25 gram millimoles per 100 grams of monomer. The tin compound may be added at between 10 and 90% monomer conversion. In the example, isoprene is polymerized in cyclohexane using 3-bromophenyl lithium as the initiator and 1,3-dibromobenzene as the viscosity modifier. The polymer obtained was stabilized with 2,2<SP>1</SP>-methylene-bis-(4-methyl-6- tert-butyl phenol. The polymer had a high cis content.

Weighing apparatus comprises a rigid body 4, suspended on two strings 1, 2, on which the points of application of the load 6 and an adjustable weight P are arranged. The strings are electrically maintained in vibration and means is provided for calculating the expression where Ti is the difference in periods (T 1  - T 2 ) of the strings, # is the ratio of the lengths of the strings and p is the ratio in which the strings are loaded by weight P. The Specification shows that the above expression, which is derived from the general equation of motion of the system, can, by suitable choice of parameters be made linearly dependent on the load. In the embodiment shown, unit 11 forms the difference frequency between signals from strings 1, 2, counter 12 counts a predetermined number of these difference signals and at the same time counts the corresponding number of signals from string 2. With the apparatus unloaded the latter number is arranged to be 1000, and when the apparatus is loaded the excess over 1000 is proportional to the load.

Abstract: 621,142. Valve closure members. BEESTON, J. P. July 9, 1946, No. 20491. [Class 135] A rotary plug valve having an oblique controlling edge which co-operates with a corresponding oblique edge at the intersection of the main bore of the body with an enlarged portion thereof such that in one position of the plug, when its oblique edge is wholly within the main bore, the valve is closed and on rotary movement therefrom, when the oblique edges of the plug and the body cross each other, the valve is opened. As shown in Figs. 3 and 4, the valve body is formed with a main bore 13 which intersects at an oblique edge 18 an enlarged conical bore 15, the axis AA of which is offset from that of the bore and which is provided with a branch 11. Within the body is rotatably and slidably housed a plug 19 formed with an oblique controlling edge 20 and a groove 23 for a sealing ring 24. The plug is operable by an integral stem 21 extending through a packing ring 25. On rotating the plug to a position where the edges 18, 20 are substantially parallel to each other, the valve is closed with possibly slight leakage which is overcome when the plug is moved axially and the ring 24 engages with the bore 13. In a modification, the plug is in the form of a cylindrical shell open at its inner end and provided with a V-notch on its cylindrical surface which coacts with the edge 18. In another arrangement, the cylindrical shell is extended and formed with a groove 42, Fig. 7, which engages a pin 43. On clockwise rotation of the plug from the position shown, the pin travels along the helical portion of the groove to fully seal the valve whilst on anticlockwise rotation therefrom the pin travels in the circumferential groove to bring the notch into register with the branch 11. In a further modification, the branch 11 is replaced by a bore in the stem 21 which communicates with the casing by way of a V-notch.
