Title: Method of preparing thiocarboxylicacids and apparatus therefor
IPC: C07C327/02
Filed: 1965-07-27
Abstract: A method of preparing a thioacid comprises cycling an aliphatic anhydride with a gas consisting essentially of H2S such as " acid gas " in the same direction in a continuous manner over an anion exchange resin.  Suitable apparatus is given in the drawing (not shown).  The reaction is conducted at normal pressure, and at a temperature preferably between 20-40 DEG  C. An excess of H2S is preferably used, a molecular ratio of H2S to anhydride being 1-2: 1, preferably nearer 2: 1. Any excess H2S may be recycled. The resin preferably has the functions of a quaternary ammonium or polyamine type. The "acid gas" to be used comprises 60% H2S and 40% CO2. Yields of the reaction are nearly quantitative; the product being obtained by fractional distillation of the cycling mixture.

Abstract: 137,058. Eclipse Machine Co., (Assignees of McGrath, W. L.). June 29, 1918, [Convention date]. Turning-gear.-An engine starter comprises a driving and a driven element connected by means allowing a yielding drive initially and then a positive drive. In the form shown, a starter pinion 11 is threaded to engage a screw shaft 6, which is connected to the shaft 1 of an electric or other motor by a spring 7 allowing a yielding drive. The spring is secured by studs 2, 8 to a driving-head 3 on the shaft 1 and a head 6a on the shaft 6; clutch jaws 4, 9 on the heads 3, 6<a> are normally out of engagement, but come into engagement and give a positive drive when the spring 7 is sufficiently wound.

Title: Reserve batteries
IPC: H01M6/32
Filed: 1972-08-29
Abstract: 1374771 Reserve cells McMURDO INSTRUMENT CO Ltd 29 Aug 1972 [9 July 1971] 32337/71 Heading H1B In a reserve battery comprising a plurality of cells formed by the opposed surfaces of spaced apart bipolar electrodes and the insulating casing of the battery, an aperture is provided in each electrode member to permit equalizing the electrolyte level in the cells during operation, and, to prevent growth of extensions from the electrode surface opposite an aperture, the electrode plates are so constructed that none of them presents a conductive surface opposite the aperture in another plate. As shown, the battery comprises annular bipolar electrodes 11 consisting of lead and lead dioxide layers on opposite sides of a substrate, end electrode 12 comprising only a lead layer. In operation the illustrated battery rotates about its axis of symmetry shown, and electrolyte supplied from a common source is retained in the cells by centrifugal force to a substantially equal extent in each. Growth of lead filaments from the part of electrode 12 opposite the aperture 13 is prevented by coating that part with insulating material 14. Insulating coatings 15 may also be applied round the apertures 13 on the leadcoated surfaces. Alternatively an aperture larger than apertures 13 and in register therewith may be cut in end electrode 12, the outside of which is covered with insulating material at least in the region of the aperture (Fig. 5, not shown). Instead of covering the electrode, an insulating bottom wall may be provided spaced from the electrode (Fig. 6, not shown) or in a somewhat similar arrangement the end electrode has a lead dioxide coating on its lower surface and the aperture cut therein is of the same size as the levelling apertures. In a further embodiment (Fig. 8, not shown) the battery terminal is connected to the second from the end electrode. The non-metal end plate or intermediate surfaces may be similarly constructed. In batteries according to the invention, the apertures need not be aligned, thus increasing the leakage current path, or permitting the use of comparatively large apertures.

Abstract: 1,216,382. Variable sweep wings. MESSERSCHMITT - BOLKOW - BLOHM G.m.b.H. 9 July, 1968 [1 Aug., 1967], No. 32677/68. Headings B7G and B7W. An aircraft has wings with a variable sweep angle, the angle of incidence of the pivoted section 2 of each wing being made to change as the sweep angle changes, so that the pitching moment caused by the change of position of the lifting forces on the wing is, at least in part, countered by the pitching moment caused by the wing incidence. The movable section 2 of a wing is pivoted at N about a fixed wing portion 12; the axis of pivot 3 is inclined so that its upper end is both forward of N and further from the plane containing the OX and OZ axes than N. During landing and take off, when the wings are in their least swept position, the angle of incidence is made positive so as to produce maximum lift and a nose up moment, while the tilt of the pivot axes 3 is such that the angle of incidence becomes increasingly negative as the wings are swept back. Alternatively, the angle of incidence in the least swept position may be zero, becoming negative as the wings are swept back. The tilt of pivot axes 3 may be made variable.

Title: Improvements in or relating to wireless receivers
IPC: G07C1/08
Filed: 1933-11-23
Abstract: 424,910. Coin-freed wireless receiving- apparatus. SPIWAK, A., 9, Markgraf Albrecht-Strasse, Halensee, Berlin. Nov. 23, 1933, No. 32745. [Class 27] [See also Group XL] Coin action, weight.-A wireless receiver has a plurality of station selecting plungers 86 whose operation is controlled by separate coin actuated mechanisms. The tuning condenser shaft carries a plurality of cylinders 82<a>, 82b, Fig. 19, indented at 83, Fig. 18, each co-operating with one of the plurality of plungers 86. Each plunger on entering an indentation winds a clockwork 92 which allows the receiver to operate for say one hour. The number of times each plunger may be actuated is controlled by a toothed wheel 112, having a smooth portion 112<1>. The plunger 86 carries an arm 101 which engages with the toothed wheel 112 to rotate it. The circuit for the receiver is closed by an arm 116<a>, Fig. 20, contacting with a conducting portion 114<a> of a disc on the wheel 112. When the arm 101 can no longer rotate the wheel 112 owing to the smooth portion 112<1>, the arm 116<a> contacts with a nonconducting portion 115 of the disc and the receiver cannot be operated. It is then necessary to insert a coin in the shoot 121<a> to actuate the lever 122<a> to rotate the smooth portion 112<1> of the wheel 122 past the arm 101 to allow it to engage with the teeth on the wheel 112. There are a plurality of shoots corresponding to the cylinders 82. The coins in each shoot, together with the positions of the toothed wheels 112<a>, 112b, record the number of times the groups of stations represented by the indentations in each cylinder have been received.

A load lifting crab 6 travels on rails 4 on the portion 1 through wheels 7 and on rails 5 on the portion 2 through wheels 8, the rails 5 being higher than the rails 4. When the crab 6 travels along the portion 1 the wheels 8, mounted on pivoted arms 9, are folded down into an inoperative position by springs (not shown). At the transition between the two jib portions 1, 2 guide tracks 11 transfer the wheels 8 between their inoperative and operative positions. When the crab 6 moves along the portion 2 the wheels 7 are disengaged completely.

Title: Improvements in methods of preparing, handling and distributing sugar syrups
IPC: C13B10/00
Filed: 1930-10-31
Abstract: Raw sugar melt is treated with chlorine or with an agent adapted to deliver chlorine and the melt is maintained in an inert or sterile atmosphere during transportation.  The raw sugar, which may be any well-known grade of cane sugar, is washed and melted at 150-180 DEG F. for sufficient time to sterilize it so that there will be neither yeast nor invertase present, and the hydrogen ion concentration is corrected by the addition of sodium carbonate or the like to a value of 7 to 7,5.  The melt is then subjected to a treatment with a weak solution of chlorine gas or liquid chlorine itself, and any acidity is again removed.  The melt is then pumped into suitable containers for transport and covered with a sterile atmosphere of air, carbon dioxide, or nitrogen. Means may be provided for adding further chlorine during transportation with a corresponding correction of acidity.  The sterilization may also be effected by means of an alkali or alkaline earth chloride, preferably in the form of "bleach liquor."
