Abstract: 475,497. Cylinders. DAIMLER-BENZ AKT.-GES. May 16, 1936, Nos. 13892, 13893, and 13894. Convention dates, May 16, 1935, June 13, 1935, and Oct. 28, 1935. [Class 7 (ii)] Smooth passages 8, for the flow of cooling fluid round each cylinder barrel, are formed by ribs 3 which may be corrugated or provided with grooves, projections, or small ribs, and which extend inwards from, and are integral with, curved walls 4, 6 of the block ; the inner walls may be formed by a detachable liner 7, or an integral bore, and, preferably, fore-andaft fairings 9, 10 are provided which produce streamlined passages for the cooling medium. This may be air, water or oil, and in a multicylinder engine it is supplied by a header 2 and leaves by a manifold having streamlined connections with the passages. Additional exit passages 8<1>, 8<1>, which may be formed by hollow members 13, 14, contain the valve gear. The outlets may be longer near the head which may be cooled by ribs forming separate passages 29 through which the cooling fluid is fed to the header 2. The passages 29 may be closed by a plate below the outer surface of the head, the cooling fluid space thus produced being traversed by hollow bosses for the holding- down studs and other fittings. The block has at the top and, preferably, also at the bottom a thick plate 62, which strengthens the structure and to which detachable side walls may be fastened. Many modifications of the passages are shown, some of which are symmetrical fore and aft, and some have additional passages between the cylinders. In Fig. 10, radial or helical ribs 38, which may be corrugated or provided with grooves or projections, and may alternate with corresponding ribs on the cylinder liner, form passages for the cooling fluid round the lower part of the cylinder. The fluid is admitted by a header 33, and flows, (a), by passages 51 formed by ribs 50, to the head passage 41, and (b) by ports 39, past the ribs 38, to an annular passage 40, whence it flows through passages 45 similar to the passages 8, described above. One or more pressure equalizing ports 53 may be provided, unheated cooling medium being supplied direct to these ports if desired. Partitions may divide the cooling fluid in the annular passage 40 into two separate streams. The cylinder block may be made of light metal ; alternatively, the surfaces in contact with the cooling medium may be coated with a good conductor, e.g. by spraying or by mechanical, chemical or electrical methods. The Specification as open to inspection under Sect. 91 comprises also subject-matter, disclosed in Specifications 475,545 and 475,546, which does not appear in the Specification as accepted.

Title: Improvements in and relating to cigar making machines
IPC: A24C1/18
Filed: 1933-05-15
Abstract: 403,867. Cigar-making machines. UNIVERSELLE CIGARETTENMASCHINENFABRIK J. C. MULLER & CO., 48, Zwickauerstrasse, and STELZER, B., 87, Reisewitzer Strasse, both in Dresden, Germany. May 15, 1933, No. 14060. [Class 130.] In a machine in which cigar fillers from a rolling device are introduced one at a time by a plunger 18 into the grooves 2<1> of intermittently moving moulds 2, the moulds are arranged end to end on a conveyer track and are given an increased forward movement each time the ends of two contiguous moulds come into the range of the filler-inserting position. As shown, the moulds travel over a table 1 and a recess in the base of each mould is engaged by a pin 3 on a chain 4 passing over freely rotatable sprocket wheels 5. The moulds are advanced step by step by the engagement of the grooves 21 by a pawl 61 pivoted on a lever 6, which is actuated from a cam 15 on the shaft 13 through a forked rod 12 having a roller 14 engaging a cam track 151 ; the rod 12 is connected to an arm 10<111> on a rock-shaft 11, which carries a bell-crank 10 connected by a link 9 and lever 7 to the lever 6. A roller 16 on the lever 6 normally rides over a member 17 having an inclined end 17111, so that the pawl 61 actuates the mould 2 only at the end of its movement. The member 17 is pivoted at 25 on a lever 26 pivoted at 27<1> on the machine frame, and carries a roller 171 bearing against the side of the mould 2. When the last recess 2<1> of a mould comes under the plunger 18, the member 17 is tilted by a spring 27, Fig. 4, about the pivot 25, so that the roller 17<1> enters the gap Z between two moulds. The lever 6 then falls through a gap 17<11> in the member 17 and the pawl 61 engages the first recess in the subsequent mould and makes a full stroke, bringing the recess under the plunger 18. At the end of the stroke, the roller 16 engages the inclined end 17<111> of the member 17 and moves it aside. The operation of the plunger 18 is effected by a lever 19 connected by a link 24 to the bell-crank 10.

Title: Improvements relating to connections for electrical conductors
IPC: H01R4/48
Filed: 1943-09-01
Abstract: 571,033. Two-part couplings. LUCAS, Ltd., J., and FOXALL, H. H. Sept. 1, 1943, No. 14293. [Class 38 (i)] A socket contact comprising a pair of complementary members pressed together by a pin passing transversely through the members, has a spring associated with the pin to apply resilient pressure to the members when the pin is moved axially to pass a lateral projection through a slot in the base or in one of the members and is then turned to lock it in the engaged position. In one form, Fig. 1, the spring k is located between the lower member a of the socket and collar j fixed to the pin e and stubs Project from the pin and rest in recesses m to hold the members a together with the spring-under tension. When the pin is turned the stubs pass through a slot h so that the spring pressure is released and the plug c is freed from the socket. In modifications, the spring is located between the head f of the pin e and the upper member a, Fig. 5, while the stubs g are at the lower end of the pin and engage either against the under member a, which is then constructed like the upper member of Fig. 1, or with a slotted flange n in the base o. This flange may be at the upper surface of the base or, as shown, at a point within the base so that when the stubs are released therefrom by passing through the slot h<2> they are retained by an upper flange r of the base and can be completely detached only by a further angular movement to bring the stubs into register with a slot h<1>. Single, double, or multiple sockets can be employed. Specification 564,368 is referred to.

Title: Method of making cottage cheese
Inventor: VAKALERIS DEMETRIUS GEORGE
IPC: A23C19/05
Filed: 1962-04-13
Abstract: A process for the manufacture of cottage cheese providing improved yields and more rapid manufacture, comprises subjecting milk to high temperature treatment to effect at least about 40% (preferably 60-80%) denaturation of the milk serum protein, setting the milk to form cottage cheese curd and whey, the setting being continued until a cutting acid is developed in the range of between about 0.36% and 0.40%, and cutting, casking, draining and washing the curd.  It is stated that the required denaturation may be produced by heating the milk to 300 DEG  F. or holding it at 260 DEG  F. for 12 seconds. Calcium chloride may be added to the milk in a proportion not exceeding 0.02%.  Cultured cream may be blended with the curd (which exhibits less acidity than conventional curds) to provide for a creamed cottage cheese of conventional acidity.  Detailed examples of the preparation of cottage cheeses are disclosed.

Title: Device for automatically opening parachutes
IPC: B64D17/52
Filed: 1937-05-25
Abstract: 492,777. Parachute apparatus. CLARK, D. R., and BIRD, W. May 25, 1937, No. 14463. [Class 4] Timed release-mechanism for automatically opening a parachute pack attached to a passenger or inanimate object in an aircraft, comprises a dashpot 60, having a spring-loaded piston 61, which, when released by manually withdrawing a locking bolt 48, performs a timed stroke, at the end of which it withdraws a locking-pawl 37 from contact with a ratchet-wheel 33, thereby permitting a spiral spring 35 to rotate the ratchet-wheel through gearing 29, 32, and wind the rip-cord 23 onto a drum 34, attached to the ratchet-wheel. The connection between the pawl 37 and the dashpot 60 includes a slidable setting-element 46, clamped to the piston-rod 57, and linked to a lever 39, mounted on a fixed pivot 40, and having an eccentric 38 on which the pawl 37 is pivoted. The pawl 37 is pressed downwardly by a blade-spring 41, and has a lower cam-portion 42, which, as the eccentric 38 is turned by the dashpot-piston, rides over a fixed roller 43, so as to move the pawl out of contact with the ratchet 33. The device is set by manually moving the setting- element 46 upwardly until the locking-bolt 48 springs under a shoulder thereon. The pawl 37 is thereby moved into contact with the ratchet 33. The spiral spring is then wound up by a key, fitting the squared end 80 of its pinion-shaft, and the device is ready for use. In operation, the locking-bolt 48 is withdrawn by pulling a cord 77 attached to a lever 75, having a cam-portion engaging a pin 49 on the locking-bolt. The cord 77 may be extended and wound on a spring-loaded take-up reel, attached to a passenger's seat in an aircraft, so as to be pulled automatically as the passenger leaves the aircraft. The dashpot-piston 61 is loaded by a spring 69, and the dashpot exhausts air through the hollow piston-rod 57, an adjustable needle-valve 71 and an orifice in the upper part 72 of the piston-rod. The,device is attached to the parachute pack or to a passenger. Access to the setting and winding elements is obtained through a removable cover 84.

Title: Improvements in and relating to resinous compositions
IPC: C08G8/04
Filed: 1932-05-21
Abstract: Moulding powders are derived from a precipitate which is obtained by dissolving a phenol-aldehyde resin in a water miscible solvent therefor and precipitating the resin by means of, for example, a dilute acid or salt solution.  The product may be used in moulding powders with or without the addition of fillers and colouring matters or it may be dissolved in a solvent such as dioxan to yield a lacquer.  In examples, a resin obtained by condensing cresol, paraformaldehyde, triethanolamine and calcium bromide is dissolved in alcohol, acetone or dioxan, and precipitated by means of aqueous sodium chloride.  Alternatively the resin may be dissolved in alkali or in alcohol caustic and precipitated by means of a dilute solution of acetic or hydrochloric acid.  (2) A resin derived from phenol, aqueous formaldehyde and ammonia is dissolved in alcohol, caustic soda added and then the resin precipitated with dilute hydrochloric acid.  (3) A resin derived from cresol, aqueous formaldehyde, ammonia may similarly be used.  (4) A resin giving a permanently fusible precipitate is prepared by reacting phenol, aqueous formaldehyde and water and precipitating the resin by means of acid from its solution in an alcoholic alkali.  It may be converted into an infusible state by the addition of methylene containing bodies such as hexamethylenetetramine and moulding under heat and pressure.  (5) A resin giving a curing precipitate is prepared from phenol, paraformaldehyde and dilute hydrochloric acid.  (6) The resin of example 3 is made into a varnish, using dioxan, acetone, alcohol or alcohol benzene as a solvent.

Filed: 1925-06-06
Abstract: 235,225. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts Ges.). June 7, 1924, [Convention date]. Testing physical qualities of materials. - In fatigue testing, alternating stresses are produced in the specimen by an electromagnet excited by an alternating current the source of which is the anode current of one or more thermionic valves. A valve a, Fig. 1 in combination with an oscillating circuit b and back coupling c is connected to a source of electric current with the interposition of a resistance or self induction coil d. Two amplifier valves f, h and intervalve transformers e, g are arranged in cascade connection to increase the small current fluctuations of the oscillation generator a, b, c so that they are sufficient to operate an electromagnet k which sets up bending vibration in a specimen bar m fixed at one end. The oscillations of the exciting circuit can be varied by varying the capacity and self-induction of the circuit b. The number of oscillations can be measured by a wave-measurer l loosely coupled to the oscillating circuit, or measured acoustically by a telephone By regulating the strength of current of the electromagnet and therefore the deflection of the bar, the stress on the latter may be varied. The bar if not of iron should have a piece of iron secured to it. The magnet may act on the end of the bar for tension tests, or two magnets may act on vanes projecting at right angles to the axis of the bar tor torsion tests. In Fig. 5, the test bar in is secured in a box s in which a vacuum can be produced, so as to eliminate damping by the surrounding medium. The magnet k may be mounted inside the box or may be outside and act through a thin metal partition. The deflection of the bar may be measured by a mirror and lens or by current induced in a magnet u. A holding wire r is provided by varying the tension of which the natural period of vibration of the test bar may be adjusted.
