Title: Improvements in or relating to shoe upper conforming machines
Inventor: BOSWORTH GEORGE HARRY
IPC: A43D25/06
Filed: 1963-07-23
Abstract: 1,087,224. Boots &c. BRITISH UNITED SHOE MACHINERY CO. Ltd. Oct. 21, 1964 [July 23, 1963; Feb. 7, 1964], Nos. 29022/63 and 5289/64. Heading A3B. A heel and lasting machine includes a pair of wipers arranged for advancing and closing movement, a support for the last and pneumatic means for raising the support, the shoe being urged towards the wipers solely by means of air under pressure while the wipers perform their wiping action. The last L is supported on a jack post 4 in a jack 1 which can be swung about a pivot 6, from a forward loading position to an operative position in which the shoe engages a heel band (not shown), by a pneumatic piston and cylinder 13. The jack post 4 is raised by a thrust diaphragm 43 which acts on a plate 141, when air under pressure is supplied to chamber 133, to raise a thrust rod 143 which in turn raises the jack post 4. A hold-down 8 positions the shoe with respect to the wipers (not shown). The machine includes an automatic pneumatic control circuit which can be set to perform either a two stroke wiping cycle in which the wipers are advanced and closed twice or a four stroke wiping cycle. In operation after loading the shoe on the jack 1 the operator depresses a treadle 5 to a first position which causes the jack to swing to its operative position, quickly at first and then slowly so that the shoe does not contact the heel-band too violently and just before the shoe contacts the heel band causes the jack to be raised until the shoe contacts the hold down. At this stage the cylinder 13 and thrust diaphragm 43 are operated by air at low pressure so that the operator may adjust the position of the shoe and release of the treadle 5 will cause the jack to be lowered. Depression of the treadle 5 to its second position then causes air under high pressure to act on the diaphragm 43 and piston and cylinder 13, the heel band clamps the shoe and the wipers advance and close two or four times as desired. At the completion of the final stroke of the wipers the hold down 8 is retracted and tacks are driven into the margin of the upper. Before the wipers are retracted the heel band releases the shoe and the jack post presses the shoe against the wipers with full bedding pressure. The jack post 4 is then lowered and the jack 1 swings to its loading position, the wipers are retracted and the machine comes to rest.

Title: Improvements in protective cut-out systems for alternating electric networks
IPC: H02H3/14
Filed: 1935-10-22
Abstract: 454,292. Protective cut-out arrangements. TASSERON, W. H., 24, Conradkade, The Hague. Oct. 22, 1935, No. 29089. Convention date, Nov. 7, 1934. [Class 38 (v)] A cut-out apparatus for protecting metallic parts of A.C. plants against high voltages utilizes the decrease in voltage resulting upon a failure between one of the phases and earth to effect the switching-off of the phase in question. The supply 1 has its star point 2 earthed at 4 over a resistance 3, and supplies consuming circuits 7, 8 over the phase lines 5 and neutral 6. The circuits 7, 8 are controlled by mercury switches 9, 10 which are retained closed by coils 11, 12 connected between the phase line and earth 15, 16 in series with resistances or lamps 13, 14. If a phase line comes in contact with a machine casing or with, as shown, a piece 18 of earthed iron structural work, the resultant volt-decrease on the coil 11 or 12 is inadequate to hold the switch closed. The service to the faulty consumer cannot be restored until the failure is removed, but the other consumers can switch on again at once. When service is being restored after a severe shut-down, immediate disconnection of supply due to the initial current-rush is prevented by employing switches with differing time-lags or glow lamps 13, 14 of different ohmic values. In Fig. 2, the parts are enclosed in a casing 20 having an earthing terminal 22 and line terminals 21, 23, and a switch 24 is provided to restore service after switching-off due to breakdown. The resistance 3 is so chosen that with a complete short-circuit the parts becoming live will only attain a potential of, for example, 24 volts to earth.

Title: Improvements in the carbonisation of carbonaceous materials
IPC: C10B1/04
Filed: 1938-10-07
Abstract: 519,246. Coking processes and apparatus. GAS ENGINEERS, INSTITUTION OF and DENT, F. J. Oct. 7, 1938, No. 29109. [Class 55 (i)] Coal and the like is carbonised in a current of hydrogen or gases containing hydrogen under pressure substantially above atmospheric, for example 25 atmospheres, the exothermic reaction between the hydrogen and the charge being initiated by local heating to form a zone of reaction and high temperature which travels through the charge. The local heating may be provided by combustion of a part of the coal, by electrical heating, or by temporarily heating the hydrogen to 600‹C. or higher. Once the reaction has started, no further heating is necessary. Coke of high reactivity and a gas of good calorific value is obtained. A cylindrical metal retort 1 may be used mounted on trunnions 4, the hydrogen being admitted through pipe 5, and the distillates withdrawn through an outlet 6, the charge being supported on a grate 7. Caking coals are treated in the retort shown in Fig. 2 in which water cooling pipes 11 are arranged at the top, finer parts of the screened coal being arranged around the inner wall of the retort and at 12 around the inlet pipe. The metallic lining 9 is cooled by water in helical grooves 10 between the lining and the retort wall. Impervious plastic zones are formed adjacent the wall and at the top of the charge, and prevent channelling of the gas along the wall.
