Abstract: 1,248,244. Turn button fastener. EATON YALE & TOWNE Inc. 24 Dec., 1968 [13 Feb., 1968], No. 7047/68. Heading E2A. A window fastener comprises a handle 12 pivoted at 11 to a plate 10 the handle having a recess entered by a spring biassed plunger 13 when the handle is in its window securing position, to fasten the handle in that position. A key 15 may be inserted through a hole 16 to depress the plunger and permit the handle to be moved to release the window. In a modification the plunger is made of two parts (17, 18, Fig. 4, not shown) the upper part normally occupying the recess in the handle 12. When the key 19 is inserted the length of its pin is such that the line of division between the two parts (17, 18) co-incide with the-division between plate 10 and handle 12. This construction overcomes the disadvantage of the first construction wherein if the plunger 14 is depressed further than is necessary sufficient movement of the handle is permitted to allow misalignment of plunger and recess. More than one bore and recess may be formed in the plate and handle respectively, the key then having more than one leg.

[Also in Group XL (c)] i In apparatus for producing off-centre marker rings on a radar display (see Group XL (c)), a voltage proportional to the varying range R (Fig. 1) is produced by combining voltage waveforms representing the varying co-ordinates x, y and shift voltages X, Y representing the co-ordinates of a point P from which the range is measured. This is effected in a circuit (Fig. 5) in which the co-ordinate voltages x, y varying in sawtooth manner are applied to the grids of valves V1 and V7 respectively where they are added to shift voltages X, Y to produce the new co-ordinate voltages (x - X) and (y - Y). These voltages are fed directly and through sign changing valves V2 and V6 to diodes V3, V5 which select the positive outputs. These are then fed to a diode circuit V8, V9 which vectorarily adds them to produce the desired range voltage R.

Title: Improvements in or relating to the manufacture of adsorptive or catalytic gels
IPC: B01J13/00
Filed: 1932-03-15
Abstract: Hard, granular, porous gels having catalytic or adsorbent properties are obtained by peptizing a hydrous oxide "precipitate" (as opposed to a true hydrogel) with an organic acid such as formic, acetic, or chloracetic acid, and nearly dehydrating the peptized mass, as by subjecting it to a current of air at 105-150 DEG  C.  The precipitate treated may be prepared in an acid or alkaline medium according to the character of the oxide and may contain a mixture of different oxides.  Washing of the precipitate before peptization is preferred, and the latter operation, which may be performed at temperatures of 10-95 DEG  C., is advantageously carried out with agitation, for instance the mixture is subjected to a combined rubbing and stirring action. Preferably the peptized mass is dried without washing and washed afterwards only if drying has been followed by activation at a temperature above 200 DEG  C.  Oxide precipitates which may be treated according to the invention include those of iron, aluminium, vanadium, copper, nickel, titanium, thorium, manganese, chromium, zirconium, bismuth, gallium, beryllium, indium, cerium, scandium, silicon, germanium, tin, tantalum, molybdenum, and tungsten.  An alumina gel prepared according to the invention may be used to extract water vapour from gases containing carbonaceous matter, since heating to 800-1200 DEG  F. to burn out the carbon does not destroy its efficiency for further adsorption.  The Specification as open to inspection under Sect. 91 comprises also the following subject-matter: the use of any peptizing agent, including an alkaline substance when the precipitate is prepared in an acid medium, or in the case of alumina, when it is prepared in an alkaline medium.  This subject-matter does not appear in the Specification as accepted.

A camera having a mounting for a percussivetype photo-flash lamp 2 is provided with a firing mechanism therefor, the firing mechanism comprising a metal spring 14 fixed at one end by a block 16 and having its other end aligned with the position of the primer 8, 10 of a fitted lamp; a cocking lever 13 for displacing the spring 14 away from the lamp primer; a latching hook 20 for holding the spring in the cocked position; and an actuating plunger 23 which, when depressed, pivots the hook 20 away from the spring 14 which then moves rapidly to hit the primer cup 10 thereby promoting ignition of the fulminating material therein. Depression of the plunger 23 also trips a shutter release lever 29. A time delay between shutter opening and lamp firing may be introduced by shortening the plunger 23. The firing spring cocking mechanism may be actuated by the film transport and cocking of the shutter (not shown). In another embodiment Fig. 2 (not shown) the spring (14<SP>1</SP>) is about half as long and is formed as a straight single leg, rather than as an L- shaped member. In a third embodiment Fig. 3 (not shown), the spring (50) is locked in cocked position by a block (43) which is laterally displaced by means of a plunger (64) to free the spring. In the embodiment of Fig. 4 (not shown), the lamp (70) is of a different type, but the firing mechanism is similar to that of (Fig. 3). The lamp (70) has a depending primer tube (73) seated in a groove (75) of a supporting block (74). The firing spring (78) is arranged to strike the side of the primer tube (73).

Abstract: 686,065. Windings for dynamo-electric machines. BRITISH THOMSON-HOUSTON CO., Ltd. April 5, 1951 [April 14, 1950], No. 7918/51. Class 35. Transposition of the conductors of slotwound coils is done outside the slots by splitting each coil-side outside the slot into two groups having unequal numbers of conductors, and connecting them in inverted sequence to the conductors of corresponding groups of another coil-side, the groups themselves being alternately mutually inverted and left in the same relative positions at alternate ends of the machine. The invention is described as applied to a coil having nine double conductors 25, 26, all connected in parallel to produce two singleturn coil-sides in each slot. At the front of the machine where the novel transposition takes place, the top coil-side 27a leaving slot S52 splits into two unequal parts V, W which are separated both circumferentiany and radially, and contain conductors 1-4 and 5-9 respectively. These sections are joined, as shown in Fig. 3, by welds 29 to corresponding sections X, Y containing conductors 10-13 and 14-18 respectively of the corresponding bottom coilside 276 entering slot S14. At this end of the machine, the sections keep their relative positions, viz. the top section W is joined to the top section Y. At the rear end of the machine, shown in Fig. 4, the conductors of the top coilside 27c are, for convenience in saving space, similarly split into parts P, Q containing coils 10-13 and 14-18 respectively and are joined to sections R, S containing the corresponding conductors 9-6 and 5-1 of the bottom coil side 27d. The effect of this is the same as if the conventional method of bending the whole coil side round in one unit were used, i.e. the top conductor takes the bottom place and so on, the relative position of the groups being inverted. To save space it is possible to weld the pairs of conductors together at some of the connections as shown in Fig. 3. In a modification, peripheral space is saved by cutting the width of the conductors to half where the the two parts cross over at the loop.
