Title: Coal mining machine
IPC: E21C35/12
Filed: 1948-05-26
Abstract: 649,962. Mining machines; planers. HERRMANN, J. May 26, 1948, No. 14274. Convention date, July 8,1947. [Class 68 (i)] A double-ended combined planer and loader C is guided along a face by a foot piece 22 having secured thereto a guide beam 15 sliding in a groove 14 formed in an inclined ramp B secured to the side 10 of a scraper chain conveyer A. The assembly C is loosely attached to the foot piece by a bolt 21 mounted on the foot piece substantially at right angles to the inclined plane of the ramp. The force on the cutting blade 17 of the planer as it is urged into the face causes the planer to rotate about the pivot pin a limited amount with the result that the following idle cutter 18 is clear of the face and friction is reduced. This movement also results in the lower portion of the cutting blade 17 being forced downwards towards the floor. An endless rope 16 is connected to the ends of the beam 15 for haulage purposes.

Title: Improvements in and relating to Tabulating Machines.
IPC: G06K15/04
Filed: 1916-10-09
Abstract: 108,942. Foster, C., and Accounting & Tabulating Corporation. Oct. 9, 1916. Record - controlled type-wheel actions.- In tabulating - machines of the kind described in Specification 2384/15 wherein a limited number of perforations in a card, in co-operation with one or more additional perforations, causes the printing of letters of the alphabet from different series, the spring-actuated type drum is replaced by a type-bearing sector 1 which is similar to that described in Specification 26896/13 but is made longer to carry additional types. The type-sector is secured to a sector 1<a> bearing a pin 7, normally locked by a latch 5 to a second sector 2 having a slot g in which the pin 7 engages, both sectors being pivoted on a shaft a. In the example described in the Specification the adjustable stops 4 correspond to two series of letters and when one of the first series is to be printed, the sectors 1<a>, 2 move together until a projection 3 meets the extended stop. When printing a letter of the second series, the supplementary stop 9 is raised bv the appropriate perforation in the card and the latch 5 is moved by an extension 8 to free the pin 7, thus allowing the sector 1a to be swung by its spring y a distance permitted by the slot g in addition to that due to the extruded stop. For printing the letter Z, only the supplementary stop 9 is raised. A spring 10 carried by the sector 2 presses the sector 1<a> forward a slight distance, thus preventing accidental re-looking.

Abstract: 1,267,301. Inverting. RELIANCE ELECTRIC A.G. 25 March, 1970 [26 March, 1969] No. 14433/70. Heading H2F. In an inverter comprising a pair of controlled rectifiers 12, 14 arranged to switch a D.C. supply 30 to the primary of a transformer 21 with alternate polarity, via a tuning inductor 15, the output is stabilized by rectifying the voltage across one winding of transformer 21 and feeding it via magnetically coupled isolating inductors to opposite ends of inductor 15. As described, commutating capacitor 13 co-operates with inductor 15 so that the output across load 31 is substantially sinusoidal. Capacitor 13 has an effective capacitance in the circuit four times its actual value. In Fig. 2 (not shown) the stabilization is achieved by a pair of diodes connected to intermediate tappings on the primary winding 24.1, the D.C. side of the diodes being connected via an inductor to the tapping of a centre-tapped inductor connected across inductor 15. In Fig. 3 (not shown), a chopper comprising a bridge of two diodes and two thyristors is connected between terminal A and the cathode of thyristor 12. The conduction angle of the thyristor bridge is controlled in dependence on output voltage. The invention is also applicable to D.C.-D.C. converters.

Abstract: Rubber latex is concentrated by centrifuging, without previous evaporation, at a temperature between 45 DEG  C. and 85 DEG  C.  The resulting cream contains a greater proportion of the rubber of the original latex than cream obtained by centrifuging at normal temperatures, e.g. 83,6 per cent of original total solids at 60 DEG C. as compared with 62,6 per cent at 18 DEG  C., and the skim contains a smaller proportion of rubber.  The concentrate obtained may be compounded with the usual filling &c. agents, incorporated in the dry state or in the form of an emulsion, and in the latter case the compounded product may be further concentrated by evaporation.
