Filed: 1928-02-11
Abstract: 304,055. Butler Machine Tool Co., Ltd., and Alderson, W. Feb. 11, 1928. Shaping. - In an intermittent variable feed motion for a shaping or similar machine, the shaft C which carries a wheel for reciprocating the ram has a cam or eccentric A secured thereto and a second cam or eccentric B loosely mounted thereon. The eccentric B is capable of being moved to any adjusted position and secured there by means of a hand-operated crank b carrying a spring detent b<1> for engaging one of a number of holes b<2>. The eccentric A during its rotation oscillates a lever D provided with a spring pawl d<1> engaging a ratchet-wheel d<2> which actuates a feed screw for the work-table or other part to be fed, the lever being maintained in contact with the eccentric by a spring d<3>, a weight, or other means. The position of the eccentric B determines the retractive movement of the lever D and hence the number of teeth of the wheel d<2> over which the pawl may pass at each revolution of the eccentric A. The full feeding movement is made during the return stroke of the ram and a curtailed feed movement is made during the last part of the return stroke in order to lessen the trailing of the tool on the work. A quick power traverse motion may be combined with the improved feed motion, and the holes b<2> may be numbered to indicate the number of teeth through which the ratchet wheel moves for each position of the eccentric B.

Title: Electric impulse generator and control device utilising such a generator
IPC: H03K3/02
Filed: 1951-02-26
Abstract: 710,181. Electric control circuits. HEWITTIC SOC. AR.L. Feb. 26, 1951 [March 6, 1950], No. 4652/51. Class 40 (1). A pulse generator for controlling a regulator circuit in accordance with the duration and sense of the pulses comprises a D.C. source 1, (Fig. 2), charging a condensor 3 until the voltage is sufficient to energise two relay windings 5, 6 connected in series across the condenser, when relay contacts 10, 13 close a discharge circuit for the condenser to de-energise the relays and the charging cycle recommences. A potentiometer 4 in parallel with the condenser 3 and relay windings 5, 6 initially proportions the P.D's across the windings to ensure simultaneous operation. A variable D.C. voltage 7 is introduced into the circuit causing the relays 5, 6 to operate at different times, whereby further contacts 8, 9, 11, 12 produce a signal in each cycle whose sense and duration is dependent on the sense and magnitude of the variable voltage 7. The discharge circuit may be controlled by a separate relay energised through contacts 10, 13 or directly from the condenser 3. The difference in. operation of the relays 5, 6 may be caused by a displacement of the slider of the potentiometer 4, or the potentiometer sections may be sensitive to changes in temperature; light, &c. The relay windings 5, 6 may be in parallel, and the operation time affected by auxiliary windings fed by the variable voltage 7. The condenser'3 may be duplicated and fed through the potentiometer whose slider position is dependent on a variable, or the apparatus may be A.C. operated and the potentiometer replaced by two inductors 21, 21' (Fig. 7) affected by the variable, charging two condensers 3, 3' through rectifiers 22, 23. In another embodiment (Fig. 8) the condenser 3 feeds into a valve 25, the potentiometer 4 being in the cathode circuit, so that the relays are only affected for a short time iri each cycle.

Filed: 1955-02-16
Abstract: <PICT:0781994/III/1> <PICT:0781994/III/2> In a process for the fluidized calcination of finely divided alumina hydrate, said material is successively treated in at least three stages including at least one preheating bed A, B, a calcining bed C maintained e.g. at 1600 DEG  to 1800 DEG  F. by the combustion of fuel therein and a cooling bed D e.g. at 800 DEG  to 1000 DEG  F. through which a fluidizing gas also passes successively in the opposite direction and at least a part of the solids entrained in the gas discharging from the, or the initial, preheating bed is separated from said gas and transferred directly (via line 63) to the cooling bed.  In Fig. 1, to which the above letters and numeral relate, heat is initially supplied to the reactor by means of torch 70 having fuel and air lines 71 and 72, but afterwards it is necessary only to supply fuel through one or several conduits 73 to the reaction zone.  In the preferred embodiment (Fig. 2) the separated solids are returned to a portion 29a of the cooling bed (e.g. at a temperature of 1000-1300 DEG  F.) confined by a baffle 75 having an opening 76 therein for passage of the solid to the remainder of the bed, where a temperature of 700 DEG  to 1000 DEG  F. may obtain, before cooling and discharge. Examples are given: in the first, temperatures of about 330 DEG , 690 DEG , 1700 DEG  and 900 DEG  F. obtain respectively in beds A, B, C and D and the product had a loss on ignition of 0.6 per cent and absorbs on ageing in a moist atmosphere, 2.4 per cent by weight of water; in the second example the temperatures were about 420 DEG , 800 DEG  and 1800 DEG  F. in beds A, B and C respectively and in a cooling bed having an area divided in the ratio 1:5, the smaller, mixing zone was at about 1300 DEG F. and the cooling bed proper at about 825 DEG  F.

Title: Improvements in thermionic valve amplifying systems
IPC: H03F1/08
Filed: 1926-02-18
Abstract: 248,731. British Thomson-Houston Co., Ltd., (Assignees of Rice, C. W., and Kellogg, E. W.). March 3, 1925, [Convention date]. Thermionic amplifiers. - In a valve amplifier particularly for use with rectified A.C. supply, the polarizing winding of a telephone acts as a smoothing choke, and the grid bias is obtained from a potential drop in the plate circuit and varies with the current in the latter. The input is applied to a jack 11, its D. C. component being shunted through the choke coils 35, 36, wound upon two cores 37, 38, which can be fitted together to form a closed magnetic circuit as shown,. The coils are oppositely wound so that stray magnetic coupling with the output of the system may be prevented, and the choke may be screened by an earthed metal casing 41. The grid G1 of the first amplifier 1 is connected to a variable tapping 34 on the input resistance 33, and the amplifier 2 is resistance-coupled to the amplifier 1. The output is applied through a transformer 26 to the moving coil 27 of a receiver, this coil being adapted to actuate a diaphragm (not shown) and located in the airgap of a pot magnet 29 which is polarized by the coil 15. The circuit of the coil 27 is closed bv the switch arm 40 after the switch 39 has closed the filament heating circuit of the valve 1 and the primary circuit 5 of the transformer which supplies filament current and plate voltage to the remaining valves. The plate circuit of the valve 2 passes from the plate P2 through the primary of the transformer 26, magnetizing coil 15 of the receiver (which acts also as a choke) middle point of the winding 8, rectifiers 7, winding 6, earthed line 20', resistance 30, winding 9, and filament F2. Condensers 24 and the choke 25 serve to smooth the plate voltage derived from the rectifiers F. The grid G2 is connected through the resistance 31 to a point which is separated from the filament F2 by the resistance 30. The potential drop along this resistance due to the plate current thus determines the grid bias, and an excess plate current produces an increased grid bias, so that the arrangement is self-regulating. Similarly the grid bias. of the valve 1 is determined by the potential drop in the resistance 19 which carries the plate current of that valve. The winding 15 carries current additional to that passing through the valves, the extra current following a shunt path through the resistance 32.
