Abstract: 801,678. Rotating cylinder pumps. AIREQUIPMENT. Sept. 24, 1956 [Sept. 30, 1955], No. 29057/56. Class 102(1). ). In a tangential cylinder pump the block 3 is rotated and the pistons engage an eccentric track 8 through pivoted slippers 7. Each cylinder bore communicates with one end face of the block, which engages a distributor 12, and also with a recess 16, the recesses having pistons 17 which cause the block to be pressed into engagement with the distributor. Liquid is fed into the casing 1 and by the pumping action of the rotating block 3 is forced into the inlet of the distributor. In a modification in place of the recesses 16 a number of recesses in the casing communicate with the pump outlet and contain pistons which engage the block to press it into contact with a distributor which has a semispherical seat engaging a similar seat on the casing.

Abstract: 705,248. Semi-conductor amplifier circuits. GENERAL ELECTRIC CO. Nov. 20, 1952 [Nov. 29, 1951], No. 29343/52. Class 40 (6). [Also in Group XXXVI] A device comprises a plate 11 of material such as germanium, which displays the Hall effect which is secured between two layers 16 and 17 of insulation between two ferromagnetic plates 18 and 19. Input terminals 12, 13, and output terminals 14 and 15 are secured to the edges of the Hall effect material, and may comprise several layers of foil. The Hall plate is made very thin i.e. .01 inches or less, so that the output impedance of the device is high. The ferromagnetic plates help to cool the device. Fig. 2 shows the device employed as an amplifier or mixer. The device 10 is mounted between the poles of electromagnet 31 energized from source 33. Input signals are applied from source 36, and the resulting output which is proportional to the strengths of the magnetic field and the current from source 36 is applied to the grid of a thermionic valve amplifier. If the current from the source 33 which produces the magnetic field, is also varied, the output is proportional to the product of the two current sources.

Title: Improvements in or relating to chloronitroalkanes
IPC: C07C205/08
Filed: 1961-08-18
Abstract: Non-geminal chloronitroalkanes, with chlorine in the 1-position are prepared by reacting the parent nitroalkane under substantially anhydrous conditions with chlorine in the liquid phase whilst irradiating the reaction mixture with light of wavelengths from about 340 to about 480 millimicrons.  Maximum yields are obtained when wavelengths of 375-425 millimicrons are used at 20-40 DEG C. in the presence of an excess of chlorine, preferably with a chlorine to nitroalkane ratio of 10:1.  In the examples 2 nitropropane, 2 nitrohexane, 3 nitropentane and 2 nitrobutane are monochlorinated by the passage of chlorine through the nitroalkanes using light from a fluorescent lamp.  In a comparative experiment the light source is a tungsten lamp.  Other nitroalkanes mentioned are 2-nitrodecane and 2-nitro-3-methylhexane.

Abstract: 1501310 Underground gasification of coal INSTITUT NATIONAL DES INDUSTRIES EXTRACTIVES 21 July 1976 [31 July 1975] 30342/76 Heading C5E Coal or lignite in an underground deposit in the form of a plurality of layers situated at a depth of more than 500 metres is gasified by circulation of a gaseous current with filtration across the layers, obtained by injecting air or other gasifying agent through one or more boreholes drilled from the surface and by collecting in one or more other boreholes the gas produced in the deposit by the action of the gasifying agent, the gasification being carried out under pressure by alternating in a cyclic manner periods of increase in pressure up to a maximum value of 30 to 50 bars with periods of decompression down to a minimum value of 15 to to 25 bars, the seam being ignited by a source of heat introduced into one of the boreholes, characterized by the combination of a continuous production of gas and a cyclic fluctuation of pressure in the underground gas generator obtained by variation in the rate of flow and the pressure of the injected gasifying agent, the pressure of gas along the whole circuit remaining constantly below the hydrostatic pressure prevailing in the overlying terrain. Following a phase of gasification, air may be blown in to bring about combustion of fuel which has escaped gasification to convert this potential energy into sensible heat. The boreholes used for evacuating the gas may be equipped with cooling devices. The gasification process may be associated with the production of electricity in a power station.

Abstract: 426,819. Cigarette-making machines. WIX, A., 338, Goswell Road, and EDWARDS, W. F. M., 1, Kempsford Gardens, Earls Court, both in London. Nov. 9, 1933, No. 31283. [Class 130] In the production of filter-tip or like cigarettes, a continuous filling is cut at spaced positions and the lengths of filling so formed are separated bodily from one another to leave spaces for the reception of insertions, the spaced lengths of filling being enclosed in a paper tube. In the construction shown in Figs. 2 and 4, a pair of reciprocating grippers having jaws 13, 14 and 15, 16 are inserted between the tobacco filling and the paper strip or band. The grippers are carried by carriages 19, 20 which slide on parallel rods 21, and at the commencement of the forward movement of the carriages a bar 25 is raised into engagement with a lever 24 to close the jaws 13, 14 and 15, 16 and lift the filling while a rotating or oscillating knife 26 severs it. The carriage 19 is then accelerated to carry the cut length forward to form a space, and the bar 25 is lowered to enable the grippers to release the filling. The carriages 19, 20 are then returned to their initial positions. In modifications, (1) the forward movement of the cut length is effected by a separate blade after the grippers have released it ; (2) the gripper jaws 15, 16 are dispensed with, and the knife or a separate blade remains in engagement with the cut end of the continuous filling while the cut length is moved forward; and (3) the continuous forward movement of the filling is interrupted whilst the cutting and /or space-forming operations are carried out. The cigarettes produced may have an insertion in an intermediate position in the length of the cigarette, and the insertion may consist of cottonwool or a different kind of tobacco. The Provisional Specification states also that, after cutting the filling, parting-blades are applied at the line of division, one retaining the cut edge, while the other moves the severed length forwards.
