Title: Improvements in the manufacture of rubber goods from latex
IPC: C08J5/02
Filed: 1923-05-15
Abstract: 223,263. Loomis, C. C., and Stump, H. E. May 15, 1923. Coating processes.-Indiarubber latex is partially coagulated by the regulated use of coagulants to produce a viscous paste which is applied to fabrics &c., the coagulation being completed during or after the utilization of the partlycoagulated mass. To produce the partial coagulation, the protein is first converted into gel by means of formaldehyde tannic acid or a metallic salt, and the rubber is then agglomerated by means of an acid or a further addition of a salt. For example, to 100 c.c.s. of latex 10 c.c.s. of 10 per cent solution of zinc acetate may be added, followed by 1 c.c. of ¢ per cent solution af acetic acid. Alternatively, 32-34 c.c.s of a 10 per cent solution of aluminium sulphate may be added to 100 c.c.s of latex. Protective colloids, such as glue, albumen, casein, soaps, saponin, tannic acid, agar, &c. may be added to prevent too rapid coagulation. Filling and vulcanizing ingredients may be added before coagulation. Specifieations 1111*/14 and 191,474, [both in Class 70, India-rubber &c.], are referred to.

Title: Improvements in the manufacture of gas
IPC: C10J1/213
Filed: 1924-06-04
Abstract: 239,280. Humphreys & Glasgow, Ltd., and Stelfox, J. C. June 4, 1924. Producers.-In the manufacture of fuel gas by carbonizing coal bv internal heat and using the resultant coke for generating water-gas, the products obtained during the "blow" are led to recuperative chambers without passing through the coal, which is then carbonized by alternately passing through it steam superheated in the recuperative chambers and water gas. The gases mav be carburetted bv oil introduced into a carburettor placed between the generator and the recuperative chambers. The plant comprises a generator 1, a carbonizing or preheating chamber 2, a carburetting chamber 3, and recuperative chambers 4. At the junction of the combustion and preheating chamber are provided an annular flue 11 and offtake 8, and the top and bottom of the chambers are provided with offtakes 7, 9 leading to the carburettor and through which steam may be injected. The valves 7<a>, 8<a> are coupled together so that when one is open the other is closed. The steam supply is controlled by a three-way valve 13 which also operates the valves 9<a>, 12. A second carbonizing chamber may be worked in parallel with the chamber 2. During the " blow," air is supplied by a pipe 14 and the products pass through the flue 11 and the outlet 8 to the superheater 3, 4. If an " up run " follows, steam is supplied to the inlet 5, passing through the fuel column, and the mixed gases are taken off from the top of the producer through the valve 7<a> to the carburettor 3. A " down run " takes the place of or follows the " up run," steam being passed into the top of the generator through the valve 7<a> and the mixed gases led off through the valve 9<a> and the lower part of the pipe 10 to the holder. In a modification, the " blow " is continued after heating the recuperative chambers, and the products are passed through the coal direct to storage.

Abstract: 460,996. Supply systems ; automatic control systems. ALLGEMEINE ELEKTRICITATS-GES. May 8, 1935, No. 13618. Convention date, May 8, 1934. [Class 38 (iv)] Electromotive force; balancing; running generators in series.-Out - of - balance in a polyphase system is corrected by generators supplying to the network voltages compensating the negative and zero phase sequence components. Means responding to these components, and also to the positive phase sequence component if desired, automatically adjust the excitations of these machines to maintain balance and amplitude. The main star-wound alternator H is connected in series with an open delta generator G and a generator N having three superposed single phase windings, or, in dealing with an incoming supply, an open delta generator Z is inserted in circuit. All these machines may have two exciting windings such as G<1>, G<2> displaced 90‹ in phase whereby the magnitude and phase of their fields may be adjusted. The machines H, Z deal with the positive phase sequence component and may have a single exciting winding such as H<1>. The generators G, N respectively provide compensation for the negative and zero components. Automatic control is obtained by impedance networks r<1> connected to the phase conductors whereby currents or voltages in phase with and proportional to the required components are derived. These are then resolved each into two components 90‹ phase displaced and applied to the grids of separate thermionic valves V<2>, for example adapted to modify the resistance of the appropriate excitation circuits and produce fields of the correct strength and phase relationship in the generators. According to one method described the current elements of pairs of wattmeter systems w<2> arranged to effect the required resolution by suitably phased voltage windings are fed from the aforesaid impedance network and the wattmeter movements are each associated with a photo-electric cell p which determines the potential of the grid of a valve such as V<2> controlling the current in the appropriate field winding. In another form, the resolution is effected by impedance bridges associated with rectifiers, the impedance bridges being respectively arranged to give outputs proportional to the sum and difference of the current from the impedance network and a voltage from the supply network. The impedance networks are supplied from any portion of the supply network which is to be kept in balance.

Title: Scalar multiplier
IPC: G06F7/68
Filed: 1974-03-27
Abstract: 1472792 Counting apparatus; scale conversion INDUCTOSYN CORP 27 March 1974 [25 April 1973] 13631/74 Heading G4D  A scale conversion apparatus for converting a train of N pulses representing measurement in a first measuring system to or from M pulses in a second system, where M is a non-integral multiple of N, comprises means for releasing a group of the M pulses on receipt of each of the N pulses or releasing one of the N pulses each time a group of M pulses is received the size of the group being alternatively the integer next higher and next lower than the multiple according to a predetermined repetitive schedule. In Fig. 1 the apparatus is set up to convert measurement pulses in an inch scale to pulses in a centimetre scale by multiplying by 2À54. Each input pulse at 101 opens a gate 1 releasing 5 MHz pulses from a clock 2 to a shift register 4 which counts up to two or three pulses according to the Schedule and then resets and closes the gate 1. The two or three pulses which thus pass gate 1 pass to the output 107<SP>1</SP>. Each cycle of the register 4, i.e. each input pulse, causes a counter 8 to be incremented; this counter counts up to 13 resets and increments a counter 10, counts again to 13, resets, and increments counter 10, then counts to 11 and then to 13 again, resetting and incrementing counter 10 each time; when counter 8 registers an even count the register 4 causes three pulses to be released to the output and whenever it has an odd count two pulses are released. This cycle is repeated continuously releasing 127 pulses for every 50 (13+13+11+ 13) input pulses. The system is reversible by an up/down signal at 109 so as to measure positive or negative movements. By changing over an electronic switch 3, 5 the apparatus will instead divide by 2À54 or pass the pulse through direct; this switch is controlled by two signals 125, 127 respectively determining inch or metric input and inch or metric output. A detailed logic circuit is described (Figs. 2A, 2B, not shown).

Abstract: 939,787. Automatic weight control. DUNLOP RUBBER CO. Ltd. April 13, 1960 [April 22, 1959], No. 13647/59. Class 38 (4). In a sheet-coating apparatus, the weight per unit area of a strip 12 being processed between rollers 11 is measured by a back-scatter beta radiation gauge 13 the output of which is compensated for variation in composition of the strip by the output of a back-scatter betaradiation gauge in a weight control unit 15 as disclosed in Specification 877,685. The direct current signal from the weight control unit, representing in sign and magnitude the deviation of the weight per unit area of the strip from a predetermined value is fed through an amplifier 16 to Schmitt trigger circuits 19-22, of which circuits 20, 21 are responsive to positive and negative deviations exceeding a first limit and circuits 19, 22 are responsive to a second deviations exceeding a second limit. The triggered signals from the Schmitt circuits are fed to a timing system for a nip motor 10 consisting of Schmitt circuits 23-25 and two valve relay circuits for positive and negative correction contain in the circuit 26. When a deviation greater than the first limit operates circuit 20 or 21 the circuit 26 feeds a signal to a motor run timer 23 if the deviation persists for a predetermined time. The motor timer 23 closes a switch 17 to drive the nip motor 10 for a short time. The output from circuits 20, 21 is also fed to a circuit 27 detecting the sign of the deviation and actuating a reversing contactor 18 so that the nip motor 10 is driven in the direction required to correct the deviation. The circuit 27 also feeds a circuit 28 which alters the time constant of the circuit 28, when the sense of the deviation is reversed from that of the previous deviation, so as to increase the duration of the motor run to take up the backlash in the nip motor drive system. When the deviation exceeds the second limit a timer 24 is actuated for a longer time. A timer 25 responsive to the signal to the switch 17 controls the operating sequence of the timer 23, 24.

Title: Apparatus for making tabs in crown caps
IPC: B21D51/48
Filed: 1964-04-02
Abstract: 994,962. Punching. H. A. L. VENNER. (National Can Corporation). April 2, 1964, No. 13679/64. Headings B3A and B3W. An apparatus for producing a crown cap having tongues of inverted U-form in the annular skirt which are anchored thereto by narrow zones at the base of the skirt comprises means to hold the cap bowl towards a punching mechanism, a punching mechanism comprising a body having mounted thereon a shaped punch for each tongue and means for reciprocating the body and the cap holder relative to one another in a direction transverse the lie of the cap in the holder. The cap, Fig. 12, has three tongues cut in the skirt 16. A cut 18 extends radially from each tongue. To remove the cap, the tongues are bent until the attachment at the base of the skirt breaks and the cap is then pushed off the bottle. The apparatus comprises a stand 21, a feed hopper 22, an intermittently rotated work carrier 39 and a punching mechanism 24. Punching mechanism.-A casing 31 contains a punch holder consisting of a leading section 32 and a trailing section 33, the leading section 32 being shaped at 34 to engage in the bowl of an uncut cap 30. A spring 35 tends to separate the parts, the separation being limited by a rod 36 which is anchored to the leading part by a cross-pin 37 which can move in a slot 38 in the part 32. A die 23 rests on the base 42 of the mechanism and has a spring-loaded ejector 28 which lifts each cap into the plane of the work carrier 39. Equally spaced round the trailing section 33 are three shaped punches 51, Fig. 9, which are held in grooves 52 by a circlip 54. In alignment with each of the punches 51 is a stud 56 acted on by a spring 57. A tappet 58a is located in a bore in the casing 31 above each stud and is engaged by a push rod 58 secured in a plate 74 which moves with the trailing section 33 of the punch holder. An uncut cap 30 is brought into position by the work carrier 39 and is first pressed into the die 23 by the leading section 32. As the trailing section 33 continues to move the spring 35 collapses and the punches 51 partially shear the tongues 15. The push rods 58 have already engaged the tappets 58a and pushed down the studs 56. As the punches are withdrawn the studs 56 engage the tabs 15 and push them back to their original positions in the skirt of the cap. The radial cuts 18 are made by three knives 75 in the floor of the die which co-operate with notches 76 in the face of the leading section 32. Actuating mechanism.-A motor 26 drives a gear-box 64 the output shaft of which drives the hopper agitator and an arm 63. At each revolution the arm 63 engages a star wheel 67 and moves it through 60 degrees, the motion being transmitted to the work carrier 39 by a shaft 41. A roller 70 on the arm also engages a lever 71 and actuates a press ram which engages the top 73 of the rod 36.
