Title: Improvements in or relating to tilting tripod-heads
IPC: F16M11/12
Filed: 1958-11-25
Abstract: 884,422. Tilting tripod heads. KARPF, N., [trading as LINHOP, N. KARPF-KOMM.- GES.]. Nov. 25, 1958 [Nov. 29, 1957], No. 37886/58. Class 97(1). In a tripod head for supporting cameras and other instruments, having a camera supporting part pivotally connected to a lower part adapted to be connected to the tripod proper, the arrangement being such that the camera supporting part is able to rotate in a horizontal plane when the lower part is connected to an upright tripod there are provided a first locking means for locking the camera supporting part against movement relative to the lower part, a handle for moving the camera supporting part pivotally and rotatably, and means for articulating the handle to the camera supporting part for universal movemeni relatively to the camera supporting part whereby the handle can be swung to a convenient operating position relative to the camera supporting part, the means for articulating the handle comprising a ball-and-socket connection, this connection being adapted to comprise a second locking means for locking the handle against movement relative to the camera supporting part. As shown in Figs. 7 and 8, a socket 21 is mounted directly on the camera supporting part 20 of the head and engages a ball 23 carried by the handle 19. The ball-and-socket are clamped by turning a wing nut 26 which forces the two sides 25 of the socket together. Clamping of the camera supporting part to the lower part is effected by screwing the handle 19 into the sleeve 27, thus forcing a bolt 28 into a tapered groove 30 in the lower part 31 of the head. So that the handle can be operated from the left or right sides, the connecting piece 21 may be unscrewed and replaced in hole 32. In a modification (Figs. 3-6, not shown) the ball is mounted at the end of a horizontal shaft about which the camera supporting part rotates, and is rigidly fixed thereto. The handle carries a socket engaging the ball and can be clamped thereto by rotating the handle about its axis. In a further modification (Fig. 10, not shown) the socket is carried by the camera supporting part and the ball is split into two halves which may be forced apart by threaded wedge pieces thereby locking the ball-and-socket connection on rotation of the handle.

Abstract: 1,196,170. Vibration dampers for bearings. REACTOR CENTRUM NEDERLAND. 18 Aug., 1967 [13 Sept., 1966], No. 38255/67. Headings F2A and F2S. [Also in Division G1] Radial movement of a bearing 4 supporting an axle 2 on which a body 1 rotates is damped by a plurality of masses 5, 7, 9 each of which is subjected to a radially directed restoring force and damped by immersion in a liquid. The damping masses are resiliently interconnected by a solid spring and/or by the liquid. As shown the first damping mass 5 is attached to the bearing 4 and is connected by a resilient rod 6 to the second damping mass 7. The latter is connected by a like rod 8 to the third damping mass 9 which in turn is connected by a third such rod 10 to the base of a liquid-filled container 11 in which all the damping masses are housed. The individual damping masses may, as shown, be of different dimensions as also may the associated resilient rods. The system as a whole can thus be effective for each of three distinct critical frequencies of vibration. In alternative constructions (Figs. 2 to 5, not shown) somewhat more elaborate systems operating on the same principle are depicted. In particular the damping masses need not be arranged "in line" as shown but rather in a "zig-zag" layout to provide a more compact structure. Also individual damping masses may have separate liquid filled containers so that a different liquid, and hence a different damping characteristic may be used for each. Fig. 6 (not shown, but see Division G1) shows the Fig. 1 system embodied in a gyroscoscope.

Abstract: 1317637 Internal resistance heating NUKEM NUKLEAR-CHEMIE UND-METALLURGIE G.m.b.H. 11 Aug 1970 [16 Aug 1969] 38576/70 Heading H5H Uranium carbides, plutonium carbides or mixtures thereof are fused by passing an electric current through a powdered charge of the material, the charge 8 being located in a cylindrical tube 4 and supplied with current through electrodes 3, 5 which seal the tube ends, at least one of the electrodes 3, 5 being displaceable in the tube 4 to maintain electric contact with the charge 8 as its volumes reduces during melting. As shown the electrodes 3, 5 are made of graphite and the upper one 3 is vertically movable under gravity during melting. The tube 4 which is quart glass is surrounded by ballast 7 composed of the same material as the charge. A water cooled gas-tight copper crucible 6 has feed and discharge pipes 9, 10 for supplying inert gas or evacuating it. In an alternative embodiment (Fig. 3, not shown), for producing uranium and plutonium carbides from a mixture of uranium dioxide, carbon, and plutonium dioxide the upper electrode is tapered or of reduced section at its lower end so that during the formation of the carbides a gap is left between the edge of the upper electrode and the tube 4 to permit carbon monoxide to escape. On formation of the carbides the upper part of the descending upper electrode makes a tight fit with the tube 4 and subsequent heating with increased current fuses the charge. The tube 4 in this case is aluminium oxide. In this embodiment the ballast is omitted and a graphite crucible is situated inside the copper crucible. In Fig. 2, (not shown), both electrodes are movable and the quartz tube 4 is secured inside a water cooled copper block. After fusion, the lower electrode is removed and the upper electrode forces the melt into a waiting container. This apparatus may be installed and operated in a glove box containing O 2 , H 2 O and nitrogen under reduced pressure.

Title: New amino ethers and process for their preparation
IPC: C07D295/092
Filed: 1957-12-17
Abstract: The invention comprises compounds of the formula <FORM:0821204/IV (a)/1> and their addition salts (wherein the groups R are the same or different and, when individual groups, are alkyl groups with not more than four carbon atoms or, when pairs are linked together, form with the adjacent nitrogen atom a mono-nuclear heterocyclic ring, for example a pyrrolidino, piperidino, morpholino, piperazino or 4-alkyl-piperazino ring), and the preparation thereof by converting 1-n-butoxy-4-hydroxy-benzene by known methods for the etherification of a phenol to an amino ether of the above general formula, preferably by reacting an alkali metal derivative of 1-n-butoxy-4-hydroxy-benzene with a diamino-halogeno-propane of the formula <FORM:0821204/IV (a)/2> <FORM:0821204/IV (a)/3> (wherein Hal is a halogen atom).  During the reaction, an isomerization of the compound of formula II or III takes place and a mixture of products is obtained.  The desired isomer of formula I is separated from the other by, for example, forming acid addition salts of the isomers and fractionally crystallizing the salts from a suitable solvent.  The term "known methods" refers to methods heretofore used or described in the chemical literature.

Title: Electronic reference isochronous period generator and applications
IPC: G04G3/02
Filed: 1973-08-15
Abstract: 1416941 Frequency dividers; electronic time pieces DYNACORE SA 15 Aug 1973 [24 Aug 1972] 39595/73 Heading G4D [Also in Division G3] A generator for providing isochronous pulses, such as for driving a clock, watch, computer &c., comprises a high frequency oscillator 1 feeding a counter 4 which is reset to zero each time it reaches a predetermined count stored in a programming device 5 which has means for receiving a standard reference period and redetermining the predetermined count in accordance with the period. Normally the counter 4 counts from the oscillator 1 through a selector circuit 2; its parallel outputs sbm are compared with a predetermined value in a memory 6 by a coincidence circuit 8 which delivers an output pulse at SS and resets the counter via a reset circuit 11. The output may for instance be at one pulse per second to control the balance wheel or tuning fork of a watch or a stepping motor of a clock. The reference period is determined by two spaced pulses applied at ER. These may be derived from a flashing light or magnetically, requiring no connections, if the generator is in a watch. The application of the first pulse causes the counter to be reset to zero via the reset circuit 11; a gate circuit 7 to be enabled so that the memory follows the output sbm of the counter; the output SS to be inhibited by a circuit 9 and the input selector circuit 2 to be changed over so that the counter now counts at a reduced rate (e.g. <SP>1</SP>/ 10 ) via a divider 3. The application of the second pulse then restores all the circuits; thus the memory which now contains a count equal to the reference period is disconnected from the counter by gates 7 and normal counting continues. The ratio of the output period at SS to the standard period may be varied by altering the division ratio of divider 3; a circuit p may be included to do this according to a coded signal applied to ER. In an alternative arrangement (Fig. 1B, not shown) the counter may be reset to the value in the memory and then count down to zero; the coincidence circuit 8 can then be replaced by a simpler null detector; when redetermining the period the counting direction is changed and the counter counts up as above.
