Title: An improved Die Control Means for a Moulding Press
IPC: B30B11/02
Filed: 1968-09-23
Abstract: 1,190,170. Moulding powdered material. MANNESMANN-MEER A.G. 23 Sept., 1968 [27 Sept., 1967], No. 45057/68. Heading B5A. [Also in Division F2] In a moulding press for granular or powdered material, a die 18 is upwardly displaced from an ejection position to a position wherein it dwells whilst charged by filling means whereafter a punch 3 descends to compress the material which descent also displaces the die 18 downwardly into an intermediate position whereafter, as the punch is being raised, the die 18 is lowered into its ejection position wherein it dwells during ejection. The punch 3 is actuated from a shaft 10 by a crank (11), actuated toggle mechanism (13, 13<SP>1</SP>), Fig. 2 (not shown), which vertically reciprocates pillars 14 to which the punch 3 is mounted. The die 18 is vertically reciprocated by a crank 8 which actuates, via a connecting rod 19 comprising two portions pivotably joined at 20, a rocking member 20 which displaces a telescopic thrust member 32, 35 to displace a rocking lever 26, pivotable about a shackle 28. The shaft 10 is rotated from shaft 7 at half the speed thereof and also carries a cam 38 which displaces a follower 40 on a lever 39 connected to vary the position of the pivot 20, against a tension spring 37, and hence the effective length of the connecting rod 19; the cam 38 having opposed peaks whereby the effective length of the connecting rod 19 and the action of the crank 8 on die 18 is increased, and one intermediate narrow portion which is wider than the other. The wider intermediate cam portion permits displacement of pivot 20 to permit the crank 8, during one revolution thereof, to displace the die 18 downwardly to the ejection position, wherein it dwells at a cam notch 44, and then upwardly therefrom to the filling position, and the narrower intermediate cam portion permits additional displacement of pivot 20 to cancel the effect of crank 8 during the downward compression stroke of punch 3 when downward movement of die 18 under the action of the punch is absorbed by compression of a spring 36 within the telescopic thrust member 32, 35.

Two sets of tangential inlets may be provided, Figs. 11, 12 (not shown), together with a central spinner injecting air or gas into the main gas flow, together with fuel if afterburning is required. In Figs. 13, 14, (not shown) vanes (120) are provided in the main flow-path, as well as two sets of tangential inlets. Again, Figs. 15, 16 (not shown), part of the main flow is directed outwardly into the by-pass duct tangentially to rotate the by-pass air, and the remainder is rotated by inclined vanes (130). Also, Fig. 17, (not shown), the exhaust nozzle rotates to rotate the exhaust. The nozzle may also have inclined vanes (161). The by-pass air may be fed tangentially into the main exhaust gas stream prior to the mixture entering the rotating exhaust nozzle.

Dyes if the following formulae are specified: <FORM:0957119/C3/1>ALSO:Hair such as human hair or fur is dyed by applying a dyeing agent containing an anthraquinone dye which is free from acid groups and has attached to the anthraquinone nucleus no hydroxyl groups but at least one aliphatic residue attached via a hetero-atom, the said aliphatic residue being (a) a hydroxy-alkyl or alkyl ether residue, the alkylene chain of which is interrupted at least once by a hetero-atom or in which ether residue the alkylene chain is attached to a cyclic ether group of (b) an alkyl residue on which the alkylene chain is interrupted by an acid amide group.  Representative of dyes specified are those of the formulae:-  <FORM:0957119/D1-D2/1> The dyeing agent may also contain wetting or washing agents such as alkylbenzene-sulphonates, fatty alcohol sulphates, alkyl sulphonates, fatty acid ethanolamides and addition products of ethylene oxide with fatty acids and fatty alcohols; permanent waving agents such as thioglycollic acid, thiolactic acid, mercaptopropane- and mercaptobutanesulphonic acids; thickeners such as methyl cellulose, starch, fatty alcohols, petroleum jelly, paraffin oil and fatty acids; and other dyes.

Title: Apparatus for digital frequency multiplication
IPC: H03K5/00
Filed: 1974-10-28
Abstract: 1491735 Pulse frequency multiplication WESTINGHOUSE ELECTRIC CORP 28 Oct 1974 [26 Oct 1973] 46589/74 Heading G4D A shift register 10 holds a binary number N while a register 12 holds a number D and the circuit converts an input pulse frequency f in  to an output frequency f ont  = (N)/(D)f in . Each input pulse causes the number N to be subtracted from the value held in a third register 14. Each time that a comparator 48 detects a negative value in register 14 it delivers an output pulse and causes the number D to be added into the register 14. The registers 10, 12, 14 are 25 bit and have a maximum clock rate of 500 kHz requiring a minimum 50 Ásec. input pulse. Maximum input frequency at f in  is therefor 20 kHz. To deal with a frequency up to 80 kHz the actual input frequency is divided by 4 and the number in register 10 is fed to the subtractor 20 via a two bit delay 16 so that 4N is subtracted from register 14. To allow for N>D and still accept a high frequency input one or more additional comparators 46 are provided. If the value in register 14 is negative by more than eight times the number D then a single output pulse on the second output line is released (instead of eight pulses on the first output) and 8D is added into register 14.
