Title: Improvements relating to the Compression of Granular and other Substances.
Inventor: HUTCHINS THOMAS WILLIAM STAINE
IPC: B30B11/26
Filed: 1917-03-08
Abstract: 114,002. Hutchins, T. W. S. March 8, 1917. Extrusion presses. - Relates to extrusion presses for compressing granular &c. materials or for extracting water from peat &c., and consists in the employment of duplex rams a, b adapted to impart both a longitudinal and transverse pressure to the material. The ram a is arranged within the ram b which is operated through a toggle g, h, actuated by a crank k, the ram a being connected through a toggle o, p to a slide n connected by a rod m to the ram b. Material passes from a hopper e through a port f to the cylinder c and is compressed by the advance of both rams by the toggle g, h. The toggle o, p is then operated by an eccentric q causing the ram a to penetrate the material and impose a lateral pressure. The compressed material passes through a nozzle d. The cylinder c may be provided with perforations preferably chamfered outwards, or with a heating-jacket. In a modification, both rams are of smaller diameter than the cylinder. The ram a may have a tapered or conical nose.

Title: Improvements in radio receiving antennae
IPC: H01Q11/04
Filed: 1924-02-11
Abstract: 211,159. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Ranger, R. H.). Feb. 9, 1923, [Convention date]. Directive signalling; aerials.-Relates to wireless receiving systems employing comparatively long and low horizontal aerials, and comprises means by which the length of the aerial 1, Fig. 2, may be reduced to one-eighth or other small fraction of the wave-length whilst still retaining sharp directional characteristics with full reception for waves travelling along the aerial towards its receiving end 4 and zero reception for those travelling in the opposite direction. With this object the aerial is loaded along its length with coils 8 by which the velocity of the current wave in the aerial is reduced. An alternative method consists in a number of condensers shunted at intervals between the aerial and earth. The end of the aerial nearest the desired transmitter may beearthed through a resistance 2 in known manner. The relationship between received current and length of aerial for an unloaded aerial is shown in Fig. 3, in which the continuously-rising upper curve refers to waves travelling towards the receiving end (front-end reception), and the undulating curve refers to waves travelling the opposite way (back-end reception). Zero back-end reception is obtained when the length l of the aerial is any multiple of half a wave length (1=n#/2). With a loaded aerial, however, owing to the smaller velocity of propagation u of currents along it, zero back-end reception is obtained when u=vl/n#-l, where v is the space wave velocity, and n is any integer but is unity for the shortest aerial. The loading of the aerial is therefore designed in known manner so that currents will be propagated along it at the velocity u given by the above expression. If zero back-end reception is required for waves proceeding in a direction making an angle @ with the line of the aerial, then the aerial loading should be such that u=vl/n@-lcos@ Specification 175,315 is referred to.

[Classes 18 and 66.] The flange c<1>, Fig. 3, of the dished bottom c of a paper or like carton for milk &c. is interlocked with the shouldered portion a<1> of the body portion by forming in the bottom flange a series of outwardly displaced teeth f, tapering from the attached root portions, which become embedded in cavities a3 which are simultaneously produced in the body wall. The operation is performed with the carton body placed in a die b, Fig. 1, the bottom being arranged over it as a flat blank which is given dished form and socketed into the body by the descent of a male die d. The plunger incorporates a series of radially disposed slides e, Fig. 1, provided with cutting edges at the outer extremities and inclined faces e<1> at the inner ends ; these slides are forced outwardly, by the subsequent descent of a conical-ended plunger g, to form the teeth f and effect the interlocking engagement of the parts. After the die is withdrawn the carton edge is rolled over the flange c<1>. The die d may be electrically or otherwise heated to assist the running of the wax coating into the interstices. According to the Provisional Specification, levers fulcrumed near the rim of the die d are furnished with toothed extension pieces which are displaced outwardly, to effect the formation of the teeth by angular displacement of the levers, timed to occur after the dishing and socketing of the bottom in position.

Title: Improvements in and relating to the clarifying of solvents and oils
IPC: D06L1/10
Filed: 1922-02-13
Abstract: Oils and solvents are clarified for further use by agitating them, preferably by compressed air, with a mixture of water, glycerine and a chloride or hydrochloric acid, the last two ingredients being substantially in equal proportions.  For clarifying benzine and like solvents, a mixture consisting of 5 per cent of glycerine, 5 per cent of calcium chloride or hydrochloric acid, and 90 per cent of water, is used.  For oils, such as used lubricating-oil, 10 per cent of glycerine, 10 per cent of a chloride and 80 per cent of water is suitable.  After agitation the oil or solvent is allowed to settle and is decanted off, the dirt, grease, &c. remaining with the clarifying-agent, which may be re-used until it becomes too thick, when it may be regenerated by filtration through a sand or other filter.

Apparatus for the manufacture of saw blades having teeth 12 comprises dies 28, 32 for performing a first shearing operation on a steel sheet 10 along what are to be the edges of the teeth of the blade, so that each tooth has one edge formed in this first shearing operation, and dies 30, 34 for performing a second shearing operation on the sheet along what are to be the other edges of the teeth so that the part of each tooth shall be formed in successive shearing operations. A pair of dies 24, 26 are each provided with two side-by-side die members, the lower die 24 having die members 28, 30 and the upper die having die members 32 and 34. The first stage die member 28 is provided with a plurality of die inserts 36 and the co-operating die member 32 is provided with a plurality of punch inserts 38 which are received in complementary shaped apertures 40 in the die 28. The exposed ends of the die inserts have downwardly inclined corner portions 44 which impart a set to what are to be the tips of alternate teeth. The second stage die member 30 is provided with a plurality of die inserts 50 and the co-operating die member 34 is provided with a punch part 52. Radially projecting elements of the punch part 52 have upwardly-inclined portions which impart the required set in the upward direction. The steel sheet is fed in steps so that between the first co-operating pair of die members 28, 32 the sheet is subjected to a first forming operation and between the second pair of co-operating die members 30, 34 the sheet is subjected to a second forming operation. In the first forming operation the apertures 42, Fig. 10, are cut out and the tips of what are to be alternate teeth are given the required set by the inclined corner portions 44 of the die inserts 36. In the second forming operation the elements of the sheet which separate adjacent apertures 42 are removed and the required set in the upward direction is imparted to what are to be the tips of teeth still to be formed.

In wired relay apparatus a first carrier wave is modulated with video signals, and a second carrier wave with signals appertaining to sound programmes, the carrier waves being so chosen that one sideband of the first substantially overlaps one sideband of the other; the modulated carrier waves are transmitted over separate cable channels and a receiver may be selectively connected to either cable so as to receive either of the overlapping sidebands in order to reproduce the television or one of the sound programmes. As described six sound programmes are modulated on six sub-carriers, the frequencies of which are the seventh to twelfth harmonics inclusive of 160 kc/s. so that they lie within a single octave (thus eliminating mutual interference by harmonics of the subcarriers) and the modulated sub-carriers then modulate a carrier the frequency of which is half that of the video carrier. Choice of television or sound programmes is effected by a manual switch at a substation and the wanted sound programme is selected by connecting one of six tuned circuits across the output of the demodulator. Specification 723,122 also is referred to. Reference has been directed by the Comptroller to Specification 659,622.
