Title: A process for the production from whale skins of swollen fibrous masses suitable for the preparation of threads, moulded articles or artificial leather
IPC: D01F4/00
Filed: 1937-07-09
Abstract: 488,596. Treating whale skins. FREUDENBERG, W., FREUDENBERG, H., FREUDENBERG, O., and FREUDENBERG, R. July 9, 1937, No. 19152. Convention date, July 18, 1936. [Class 76] Swollen fibrous masses suitable for working up into threads, moulded articles or artificial leather are obtained by removing the main blubber content of whale and like skins by high pressure, e.g. in a flat press, and afterwards converting the skin in known manner by swelling and comminution into swollen fibrous masses. In addition to the removal of the main blubber content by expression, it may also be removed by extraction with a solvent, the solvent and blubber being recovered in known manner. Before removal of the blubber the skin may be freed from the outer or grain layer by treatment with caustic soda or alkali-sulphide lyes. The swelling may be effected with alkaline agents such as lime, caustic soda and ammonia or acid agents such as hydrochloric acid, formic acid or lactic acid. Different swelling agents may be used in succession. Specifications 429,039, 429,040,439,532, 445,721, and 452,348, [Group IV], are referred to.

Abstract: 758,186. Coke ovens. OTTO, C. July 29, 1952 [July 30, 1951], No. 19173/52. Class 51(2). A regenerative coke oven battery of the type comprising coking chambers extending transversely of the battery and alternating with heating walls each including a row of vertical heating flues, regenerator chambers extending transversely of the battery below the coking chambers and heating walls and communicating at their upper ends with the lower ends of the heating flues, and sole channels communicating with the lower ends of the regenerator chambers through a plurality of ports formed in an intermediate wall and distributed along the lengths of the sole channels, is characterised by the provision of valve means associated with each of the said ports and actuated by the gas flow to throttle its port when the gas flows from a sole channel into a regenerator. As shown in Figs. 1 and 5 the intermediate wall between a regenerator H and a sole channel J is formed by blocks O, each block being formed with a port 2 against the lower end of which seats a flap valve Q hinged along its upper edge at 4. The valve Q is provided with an aperture 7 whose area is smaller than that of the cross-section of the port. Inflowing gas or air to be preheated presses the valve Q against its seating, but out-. flowing waste gases force it open to increase the effective flow area. The valve Q may be replaced by a valve not formed with an aperture 7 but terminating short of the bottom edge of the port 2, Fig. 7 (not shown), and the movement of the damper may be limited by stops, Fig. 8 (not shown) to an opening smaller than would be given by the waste gases flowing at the normal rate. In a modification, Figs. 9 and 10, the chequerwork is supported in a row of blocks T- shaped to provide a guideway T<SP>1</SP> for the blocks O. The blocks T include spaced vanes T2 extending longitudinally of the battery. A further modification, Fig. 11 (not shown), has blocks O formed with two ports 2 disposed between an upwardly extending projection, the blocks being so dimensioned that the said projections meet every third regenerator division wall. In a final modification, Figs. 12 and 13 (not shown), the blocks O are supported on members formed with vanes extending below the said blocks O, and valve controlled pipes in the adjacent pillar walls conduct lean gas to the bottom of the regenerator chambers.

Title: Process for the manufacture of water-in-oil emulsions
IPC: C09K23/00
Filed: 1934-07-02
Abstract: Water-in-oil emulsions are obtained by emulsifying water in oil in the presence of an insoluble salt of the sulphuric acid ester of a normal primary alcohol having at least 8, preferably 12 to 18, carbon atoms.  Preferably the salt is produced in situ by dissolving the sulphuric acid ester in the oil and agitating with an aqueous solution of a salt of a metal, e.g. lead, aluminium, iron, tin and barium salts.  Suitable sulphuric acid esters include n-lauryl-1-sulphuric acid and the corresponding esters of myristyl, stearyl, cetyl, oleyl and ricinoleyl alcohols.  Oils which may be treated include medicinal paraffin oil, Neat's foot oil, olive oil, castor oil, cottonseed oil, linseed oil and petroleum lubricating oils.  The proportion of sulphate ester or salt thereof may vary from 0,02 per cent to 10 per cent by weight of the oil, preferably between 0,05 per cent and 2 per cent.  According to an example 50 pts. by weight of a heavy paraffin oil is mixed with 1 pt. of n-lauryl-1-sulphuric acid and stirred with 0,25 pt. of lead acetate dissolved in 48,75 pts. of distilled water.  The resulting emulsion is a heavy grease and has good lubricating properties, and may readily be extended with oil.  Water-linseed oil type emulsions are suitable for use as paints.  Specification 358,612 is referred to.

Filed: 1956-06-29
Abstract: 828,078. Velocity modulated tubes. VARIAN ASSOCIATES. June 29, 1956 [July 8, 1955], No. 20283/56. Class 39(1). A klystron resonator is tuned by means varying the capacitance of the. resonator comprising a conductive plunger 17, Fig. 1, on a narrow conducting stem 26 disposed substantially mid-way of the length of the resonator and adjacent the beam passage gap and movable towards or away from the gap. The plunger head can be flat as shown or curved to conform to the beam contour, Fig. 4 (not shown), the plunger being midway along the cavity and the drift tube ends being symmetrically placed with respect to the plunger. The plunger is actuated by worm gear 45 through threaded sleeves 45, 27, the worm gear being held against bearing surface 43 by spiral tension spring 38. Vacuum is maintained by flexible diaphragm 36 and a conducting disc 37 shunts circulating currents and so prevents diaphragm 36 from overheating. Pipes 32 and a baffle 24 in the hollow interior of the tuning shaft allow for liquid coolant flow, O-rings 33 preventing coolant leakage and a pin 34 holding connector 31 on shaft 26. The tuner parts are of non-magnetic material, e.g. generally of Cu except parts 27, 36, 38, 42, 44, 45 which are made of non- magnetic stainless steel. The worm shafts 45 extend up to revolution counters 48, Fig. 1, and are actuated by tuner drive shafts 51. The output waveguide 19 has stepped impedance transformer 21 which may be of " standard " binomial type which prevents a constant conductance to the tube over its frequency range. For maximum power transfer to the load however the conductance must vary with frequency and this is done in general by selecting suitably any one or more than one forcemeter of the transformer, e.g. length # or height h. If # <#/4 at the mid frequency of the pass band the sending end conductance decreases with increasing frequency while of # >#/4 it increases with increasing frequency. To achieve the desired sending end conductance, individual sections can have different values of # while the heights h of sections are derived from standard binomial transformer design. The impedance transformer may alternatively have one or more than two sections and can if desired be outside the vacuum envelope in which case the waveguide section between iris 18 and transformer is designed as a transformer section. 22 is a slanting output window and 23 an input coaxial line. The device is a cascade amplifier. The impedance transformer 21 transforms a low conductance load to a high conductance load. The collector 3 has a cooling jacket (not shown) and beam focusing or confining solenoid 4 associated with pole pieces 5, 6 is cooled by jacket 7. The tube is used in radar, microwave relays, or linear accelerators.
