Abstract: 1346093 Releasable fastenings CEGEBAT GP 19 April 1971 [17 Feb 1970] 21959/71 Headings E2A and E2B  Panels 1, 2 are secured in a concealed manner to a supporting rail 3 by a pivoted hook 9 which is held in the fastening position by a strip spring 19 whose ends engage recesses 20 in plate 8 of a bracket 4. The hook fastener is pivoted at 11 on the. bracket, this being screwed to the rail at 5. Bent-up guides 22 on the flange of panel 1 grip the edges of plate 8 while the hooking lever 9 engages holes 24, 25 in this flange and matching holes 26, 27 in the flange of panel 2. The fastening is freed by inserting a knife blade between the panels to engage cam surface 16 of the hook to rotate it free. The principle may be applied to solid panels (Figs. 7-9 not shown).

Abstract: 1,105,268. Tape spools. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 25 May, 1965 [30 May, 1964], No. 22008/65. Heading G5R. [Also in Division B8] A spool for a tape comprises a hub 3, 4, Fig. 1, on which the tape is wound, two flanges 1, 2 and an annular resilient member 6. When the spool is assembled, Fig. 2 (not shown), the annular member 6 is deformed by the bevelled edge of the hub portion 3 so that it is of similar shape to a projection 5 on the other flange. The gap between the member 6 and projection 5 is slightly less than the width of the tape to be wound on to the spool so that the edges of the tape are in frictional engagement with the flanges and the tape is drawn towards the hub.

Abstract: 1,003,180. Fuel injection pumps. SOC. POUR L'EXPLOITATION DES PROCEDES CHIMIQUES ET PHYSIQUES S.A. June 8, 1962 [June 15, 1961], No. 22334/62. Heading F1A. In a fuel injection pump having a piston 3 reciprocated by an engine driven cam-shaft 5, advancing of the injection timing is effected by axial movement of a spring-loaded, helicallysplined sleeve 9 coupling the engine drive shaft 8 and cam-shaft 5 to effect relative rotation between the shafts, such axial movement being effected by pistons 11a, 11b subjected to the delivery pressure of a gear-type feed pump 14, 15, driven by the cam-shaft. Rotation of piston 3 is effected by cam-shaft 5 through gears 28, 29 and 30, Fig. 2. A by-pass valve 20 in the feed pump circuit acts to maintain the gear pump delivery pressure porportional to engine speed. Surplus fuel from the feed pump passes through chamber 23, thereby cooling the injection pump, and returns to the fuel tank via a check valve 33.

Title: Nuclear reactor core
Inventor: CROWTHER R L
IPC: G21C3/328
Filed: 1969-05-01
Abstract: 1,248,483. Reactors. GENERAL ELECTRIC CO. 1 May, 1969 [2 May, 1968], No. 22345/69. Heading G6C. A reactor core comprises two fissile fuels, one having a greater thermal neutron fission crosssection than the other and being located initially only in a peripheral region of the core. In a boiling water reactor using light water as coolant /moderator and in which the core is surrounded by water acting as a reflector, the peripheral region of the core has a steep gradient of neutron flux of relatively low energy. The fuel assemblies for use in this region comprise a plurality of elongated spaced fuel elements, the initial enrichment of the fissile fuel in these elements being graduated among the elements in inverse relationship to the neutron flux gradient. Fissile Pu may advantageously be mixed with depleted or natural U, each of the fuel elements initially containing at least 0À5 wt. per cent of fissile Pu. The spatial distribution of Pu in each peripheral fuel assembly depends on the geometry of the assembly with respect to the surrounding water reflector, i.e. the number of sides and corners of the assembly adjacent the reflector. In the embodiment described, the peripheral fuel assemblies have two sides and the included edge, or only one side and no edge, or only an edge and no side facing the reflec or, which differences result in different neutron flux distributions across these assemblies. Different spatial distributions of the Pu fuel in these assemblies are therefore required for optimum results. Local power flattening is achieved by placing the fuel of highest enrichment in the positions of minimum thermal neutron flux and vice versa. The mean fission cross-section of Pu in a thermal neutron flux is about 2À7 x that of U. Since the power generation rate is directly proportional to the fission cross-section times the neutron flux, the greater fission cross-section of Pu is an aid in increasing the relative power in the peripheral zone to thereby improve the radial power distribution of the core. The resulting more rapid burn-up of the Pu fuel also aids in matching the refuelling cycle periods of the peripheral and central zones.

The liquor may also contain natural or synthetic rubber, starch, trimethylolmelamine or other synthetic resin. The impregnated web is dried then heated at 70 to 200C for 0.5 to 5 minutes. A rayon web bonded with 10% by wt. pullulan is water dispersible whilst one bonded with 10% by wt. carboxylated pullulan plus trimethylolmelamine has high wet strength. Uses include clothing, interlinings, filter cloths, sanitary goods and packaging.

Abstract: 400,902. Indicating the frequency of periodically recurring sounds. LEITZ GES., E., Optical Works, Wetzlar, Germany. -(Assignees of Disteli, A.; Olten, Switzerland.) Aug. 15, 1933, No. 22745. Convention date, Sept. 2, 1932. [Class 106 (iii).] Apparatus for testing and regulating the frequency of periodically recurring sounds, e.g. escapement ticks, of the kind in which the sounds are converted into electric oscillations which actuate the oscillating member of an electromagnetic instrument (oscillograph) and in which a light ray from the oscillating member is directed by a rotary mirror or prism H on to a screen J, is characterized in that one electromagnetic instrument D1 is used for the sounds to be tested and a second such instrument D3 for sounds of standard frequency, a rotary mirror being used to direct both sets of light rays on to a common screen. The ticks of timepiece A to be tested are transmitted by microphone B and amplifier C to the mirror D of oscillograph D1 so that the rays F, G from source E are directed by the oscillating mirror D and rotary four-faced mirror H on to screen J. A standard time movement A1 similarly has its ticks transmitted by microphone B1 and amplifier C1 to mirror D2 of a second oscillograph D3, rays F1, Gl from source E1 passing to the same screen J. The speed of motor K is adjusted to drive mirror H at such a steady speed that the curves on the screen, caused by rays F1, G1 and the standard movement A1, are superposed one on another and therefore appear to remain stationary. The mirror H is then rotated steadily at this speed and the deviation of the timepiece A under test, from standard, is observed from the way in which its curves on screen J move in one direction or the other relatively to the stationary curve from rays F1, G1. The timepiece A is then regulated in the usual way until its curve is stationary relatively to the curve of the standard frequency. One or each microphone may be screened from the other to prevent sound interferance. The timepiece A, say, is held by clamps N on to the glass plate L which is held resiliently above the microphone B which latter is resiliently supported in a casing M of soundinsulating material. Case M is on supports O so that it can be rotated about a horizontal axis to test the timepiece in various positions. A device Q locks the case M in its adjusted position.
