Title: Improvement in devices for automatically feeding book cases to a blocking press
IPC: B65H9/04
Filed: 1930-07-01
Abstract: 354,507. Feeding book covers from piles. MURRAY, J., Mimbridge, Chobham, Surrey. July 1, 1930, No. 20002. Convention date, July 1, 1929. [Class 117.] A device for feeding book cases or covers to a blocking press comprises a magazine formed of side members 1 adjustable laterally for covers of different width, and front members 1<1> which are adjustable vertically by racks 70 operated by pinions 71 actuated by worms 75 engaging toothed segments 74. The insides of the covers, Fig. 4, are placed downwards, and they are adapted to be advanced to a blocking press comprising a bed 92 and a vertically reciprocating die-carrier 3 by means of reciprocating pushers 5 which engage the rear edges of the sides of the cover, and reciprocating guide members 34, 35, 36 which are detachably connected to a bar 32 of dovetail cross section which reciprocates in unison with the pushers 5 and with a pair of wires 43 carried by pulleys 44 mounted in pivoted arms in carriages 50 which are connected together to move in guides in side frames which also serve to support the bed of the embossing press. The covers are advanced in four stages so as to occupy successively the positions A, B, C, D, Fig. 2, and movement of the covers takes place only when the pushers and guides are moving to the right. On the return movement of the carriage, the covers are held in the positions B, C, D by means of stops 80, 104, 100, which latter strip the embossed cover from the carriage and cause it to fall into a delivery receptacle. The guide member 34 is wedge-shaped, and by acting on the edges 40 of the lowermost case in the magazine it registers the cover laterally as it moves to the left. The other guides 35, 36 are formed with parallel grooves in their upper faces, and the wires 43 grip the edges 40 of the cover against the guides so as to cause the advancement of the covers from the position B onwards. The cover is advanced to position B by the adjustable pushers 5. As the covers advance they are supported by rods. The wires 43 are mounted so that they can be adjusted laterally, and also so that their tension can be adjusted to ensure a good grip on the cover. Vertical adjustment of the pushers 5 is effected by bolts 8 which can slide along links 18 which are carried by levers 20, 21 and are adjustable vertically by turning the revers by means of a hand-operated link 28.

Title: Control system
Inventor: KUERZEL ROBERT EDWARD
IPC: G21D3/12
Filed: 1963-05-20
Abstract: 1,043,271. Nuclear power plant. GENERAL ELECTRIC CO. May 20, 1963, No. 20040/63. Heading G6C. In a nuclear reactor power plant, a turbine is supplied with steam from a boiling water reactor. The steam flow from the reactor to the turbine is adjusted by a valve, the setting of which is varied automatically in response to both the turbine speed and the internal pressure of the reactor container. The reactor control rods are moved in response to turbine speed and an over-speed device controls the valve independently of pressure. The rod control provides a long term change in reactivity while instantaneous reactor response is given by the reactor pressure control. To limit the loss of the self-regulating characteristics of the reactor, excessive changes in pressure are prevented by rendering the load control only partially responsive to the turbine load. The control signals are applied to the reactor through a rate limiter to prevent rapid reactor fluctuations in response to abrupt load charges.

Title: Improvements in or relating to the separation of minerals by froth-flotation
IPC: B03D1/06
Filed: 1925-08-12
Abstract: 262,492. Wood, L. A., and Minerals Separation, Ltd., (Lewis. C. P.). Aug. 12, 1925, Flotation processes.-Relates to the differential separation of zinc blende from associated minerals bv froth-flotation. In the case of a mixture, containing a mineral such as galena, the separation is effected by the employment in conjunction with a frothing agent, in such amount as to be wholly in solution, of a limited quantity of a metallic salt of an alkyl derivative of sulpho-thio-carbonic acid, for example an alkali xanthate, the blende being thereby prevented from floating while the galena is enabled to float. A small quantity of alkali cyanide may be present. The zinc blende may be subsequently recovered by the addition to the circuit liquor of a small quantity of copper sulphate or other cyanicide with or without further quantities of the other reagents, and, if desired, an alkali such as quicklime. An ironbearing zinc ore may be treated by agitating a pulp with lime and the xanthate, then further agitating it with a copper salt and a frothing agent, thereby producing a froth rich in zinc and poor in iron.

Title: Improvements relating to measuring devices for textiles and other goods
IPC: G01B3/12
Filed: 1928-07-17
Abstract: 320,645. Fernandez, F. G. July 17, 1928. Measures of length.-An apparatus for measuring off by hand a number of units of length of fabric or other material. A thrust rod C has a curved end meshing with the teeth of a toothed member A which is caused to advance by one unit when a push lever B is depressed and also carries a scale of numbers reading through an aperture the lengths completed. The rod returns to its initial position after each forward movement by the action of a spring E. The toothed member is under the action of a spring A<1> which tends to cause it to return to its initial position, such return being prevented by a pawl F. Before a measurement is taken, an indicator I on a slider H, held to a rod M by the friction of a coiled spring H<3>, Fig. 4<a>, is adjusted to the desired reading on a scale K. After each unit of fabric is measured the push lever is depressed and when the desired number of units is reached the end of the toothed member which has a projection Z strikes the slider and pushes the rod M to release a detent lever O, P, Q from a bar R, which is then pulled by a spring so that a waved edge on it operates the clapper V of a. bell U. Fractions of a unit are measured along the rear edge of the apparatus. On completion of a measurement a piece Y is depressed to allow the member A to return to zero and a piece S<1> is manipulated to restore the bar R.
