Title: Improvements in or relating to machines for driving tacks, rivets or the like
IPC: B25C1/02
Filed: 1927-06-28
Abstract: 294,754. Bifurcated & Tubular Rivet Co., Ltd., and Paterson, L. M. June 28, 1927. Loose-nailing.-A machine for driving loose tacks or rivets comprises a rotarv tack drum 1 mounted on a horizontal shaft 36 and having an open side presented within a recess a in a fixed casting 2. The periphery of the drum fits closely within the rim of the recess except at one side where the recess is extended as at b, c, Fig. 5, to define aT-shaped clearance. Tacks passed into the drum by a hopper 2<a> are lifted into slots d in the wall of the drum as the latter rotates and enter the clearance b, c. The latter at its lower end merges into a raceway f. Misplaced tacks are removed from the slots d by a scraper 10. The raceway f communicates by a separator 3, Fig. 1, with a lower raceway g, which delivers the single tacks separated to a pair of members 4 normally held together by a scissors spring 7, Fig. 8. The members 4 are carried by a vertically movable carrier 5 normally held upwardly by a spring 6. A driver 8 carried by a vertically reciprocable rod 17 is arranged, when it engages a tack held by the members 4, first to lower the latter to the work and then to spread them to release the tack. The mechanism is operated by a hand-lever 9 pivoted at 15 and normally held raised by a spring 16. The lever 9 passes through a slot in the rod 17, so that when it is operated it first lowers the driver to drive a tack ready placed in the members 4. At the same time it operates the separator 3 through links 35, 33, cam 32, and spring-held lever 28. When the lever 9 is released and rises, it returns the separator to the right, and rotates the tack drum through an arm 20, pawl 21 and ratchet-wheel 19 fast on the shaft 36. The tack drum has a friction drive from the shaft 36 being clutched to the latter through washers 37, 41, Fig. 5, spring 39, and wing-nut 40. The tacking mechanism is carried above a work-bench by universally-jointed links 13, 14, Fig. 1.

Title: Improvements in or relating to safety devices for use on colliery and the like inclines for stopping runaway trams
IPC: B61H9/04
Filed: 1924-07-22
Abstract: 227,060. Barradine, E. July 22, 1924. Axle stops.-In an arrangement, on a colliery or like inclined tram-road, of pivoted skotches which allow a vehicle to run up the incline, but engage the axles of the vehicle to prevent movement down the incline, a sliding bar is provided having studs which serve to throw the skotches out of action to allow the vehicle to descend when required. Skotches 1 are pivoted at 2 to angle-irons between the rails, and are balanced so that they hang normally in a vertical position. Each skotch can move freely in one direction to allow an axle 14 to pass as at A, but movement in the opposite direction is limited by stops 5, so that the axles are engaged and downward movement prevented as at B. The lower ends of the skotches are bifurcated and embrace a slidable bar 7 provided with studs 8 adapted to bear against the depending ends of the skotches and move the upper ends clear the axle path when the bar is moved to the right. The bar is connected by links 9, 10 to levers 11, 12, adapted to be operated by the axles as the vehicle leaves the incline. Lever 11 is also connected to a cable 13 which is carried along the wall or roof within reach of an occupant of a vehicle. With the skotches and bar in normal position a vehicle can move freely up the incline, its axles clearing lever 12 and moving the skotches. Should the vehicle commence to descend whilst on the incline, as by breakage of the haulage rope &c. the skotches engage the axles and arrest the vehicle. On passing off the incline the axles engage lever 11, move bar 7 to the right and raise lever 12. The skotches are then out of action and the return journey can be made. On passing off the lower end of the incline, the axles engage lever 12 and return bar 7. If required, the vehicle can be stopped on the incline by pulling cable 13, thus moving the bar to free the skotches.

Title: An improved method of moulding thermosetting synthetic resin materials
IPC: B29C43/22
Filed: 1950-07-12
Abstract: An article is moulded from a thermosetting moulding powder by applying the required design to absorbent paper of a thickness of 1.5 to 7.0 thousandths of an inch, impregnating the decorated paper with a thermosetting resin solution to give it a resin content of about 50-60 per cent. passing the impregnated paper between rolls to remove excess resin, drying the impregnated paper, moulding the article, opening the mould before curing is complete, applying the impregnated sheet to the surface to be decorated, replacing the article in the mould, completing the curing of the article and removing the moulding.  The impregnated sheet may be applied with the decorated side towards the moulded article and preheated to such an extent as to reduce its curing time to somewhat less than that of the moulding powder, and the excess resin may be removed from the paper by passing it between stainless steel rollers.  The design may be applied by printing, painting or by transfers.  The paper may be impregnated with the same type of resin as the thermosetting powder, e.g. phenol- or melamine-formaldehyde resins.  Specification 605,643, [Group VIII], is referred to.

Title: Improvements in and relating to the melting and refining of copper
IPC: C22B15/04
Filed: 1929-06-07
Abstract: 331,353. Jensen, C. A., (American Metal Co., Ltd.). June 7, 1929. Reverberatory furnaces; charging.-In the melting and refining of copper, ingots of the metal are preheated to a temperature somewhat below melting-point, and are then plunged separately into a bath of metal in the melting-furnace. As shown, the ingots in the form of slabs of electrolytically deposited metal are fed by a ram 20 along an inclined flue 24 leading to the melting-hearth 23. the tracks 29 along which the ingots move being raised above the floor of the flue, so that the heating-gases from the melting-hearth have free access around the ingots. The bath of metal is deepest at the feed end so that the ingots are immersed immediately beneath the molten metal and the slag floating thereon. The metal in a superheated state is discharged through a taphole 34 at the shallow end of the bath, and passes to a tilting refining-chamber 16, Fig. 6, in which it i s covered by a layer 36 of deoxidizing slag, and a layer 37 of carbon. The oxide from the metal passes to the slag, and the latter may be main. tained in an active state either chemically by the carbon layer, or electrolytically. Heat may be supplied either by hot gases or electrically, and two refining-chambers may be arranged in series.

Patent GB-410331-A (GB)
Title: Manufacture of phenol and apparatus therefor
IPC: C07C37/02
Filed: 1933-06-20
Abstract: In the manufacture of phenol by reaction of benzene with hydrogen chloride and oxygen and hydrolysis of the chlorbenzene with steam in the vapour phase, the hydrogen chloride from the second reaction is recovered by the process described in Specification 387,832, for example, by treatment of the reaction products with water, and is used, after extracting with benzene, for producing more chlorbenzene. A fan 1 supplies a mixture of chlorbenzene and water vapour at 100 DEG  C. to a heat recuperator 2 where it is heated to 400 DEG  C. by vapours leaving the contact furnace 4, serving for the hydrolysis, at about 500 DEG  C.  After heating to 500 DEG  C. in a preheater 3 the mixture passes to the furnace 4, and the exit vapours are cooled to 200 DEG  C. and pass to a tower 5 where the hydrogen chloride is washed out with water and chlorbenzene, the circulating vapours being enriched in these constituents.  They are then led to a tower 6, where phenol is removed by washing with hot water, and are returned to the cycle, a small quantity, however, passing to a condenser 7. Hydrogen chloride leaving tower 5 is led to a washing tower 8 and thence to a vaporizer 9.  The phenol solution from tower 6 passes to a tower 10 and is pumped back.  Towers 8 and 10 are supplied with benzene from tank 11 <PICT:0410331/IV/1> which extracts phenol, the solution passing to a still 12 where the benzene is distilled, preheated at 3 and, mixed with hydrogen chloride and air, passes to a contact furnace 13.  The chlorbenzene produced is recovered in a con-densing column 14 and returned to tower 5, unchanged benzene being condensed at 15 and fed to tank 11.  Specification 362,817 also is referred to.

Title: Improvements relating to electrical control apparatus
IPC: B61L5/18
Filed: 1943-10-27
Abstract: 582,761. Railway signals. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. (Union Switch & Signal Co.). Oct. 27, 1943, No. 17723. [Class 105] [Also in Group XXXVIII] In an electric control apparatus, one function is effected by current of one polarity in the control circuit and another by current of the opposite polarity, a polarised relay and an auxiliary relay being connected in series across the control circuit the energisation of the auxiliary relay being governed by a contact of the polar relay. As shown, the auxiliary relay N is of the biassed polar type, in which its contact 30 is picked up only when its lefthand terminal is connected, to the positive terminal of the source. In the position shown the lamp G will be lit through contact 32 of relay H controlled by relay N. If the contacts 25, 26 of the pole changer are reversed, the direction of current in the polarised relay P is reversed and causes its contacts to take up their right-hand positions, so that the left-hand terminal of relay N is still connected to the positive terminal of the source and the lamp Y is lit instead of G. If, however, the contacts fail to move to the right-hand position, the left-hand terminal of relay N will either be connected to the negative terminal of the source or be disconnected altogether. In both cases the contact 30 and thus contact 32 will fall, lighting lamp R so that, in this way, the response of relay P to changes of polarity can be checked. Coded energy is supplied over the line by code transmitters 75 CT and 180 CT and since they operate at different speeds the impulses applied to the relays will vary in length. A rectifier K is shunted across relay N to delay its release so that the picked-up and released periods are of equal length. When steady energy is supplied to the relays instead of coded energy, Figs. 1 and 3 (not shown), the relay N may be of the neutral type so that its contacts remain picked-up while the contacts of relay P change over, so preventing a flash of lamp R.

Abstract: 1,072,072. Echo suppressors. L. R. KAHN. April 28, 1965 [May 13, 1964], No. 17845/65. Heading H4R. Echo suppressor for a speech communication system e.g. using earth satellites has a switching device in each transmission path so as to transmit a speech signal including most of the frequency components of the signal over the path carrying the stronger signal, and to transmit a signal including only. a small portion of the frequency components of the speech signal on the path carrying the weaker signal. Fig. 1 shows a system in which talk/listen relays 34 and 40 are controlled in accordance with the relative signal levels in the two paths to introduce narrow band rejection filters, e.g. RF1, RF2, --RFn, in the path carrying the stronger signal, i.e. the talk path, and to introduce narrow band-pass filters PF1, PF2, - - PFn in the other, i.e. answer path. The arrangement is such that the two paths have complementary transmission characteristics, thus avoiding echoes whilst still enabling the listener to answer or interrupt at a lower level of intelligibility.
