Abstract: 340,048. Pearson, L. H., and Randall, W. J. Sept. 30, 1929. Systems for transmitting music.-In a system comprising one or more microphones for pick-ups and an associated amplifier, variable amounts of resistance are connected to the amplifier to vary its effectiveness by means controlled from a distance by impulses. The same means may be used for connecting up the appropriate microphone, &c. Specification 332,572 [Class 40 (v), Wireless signalling &c.], is referred to. As shown, there is an impulse dial A for each microphone H. When a dial is moved off-normal, its contact c is closed and sluggish relays Rl - - R3 and the back-stroke sbepping- magnet SM are operated. During the return movement, R3 disconnects the input to the amplifier, and when the dial stops the relays fall back. A particular microphone is now connected up over LI, the input transformer is shunted by a. particular resistance over L2 and the pilot lamp of the microphone concerned is lit over L3 to a particular degree of brightness depending on the shunting resistance connected up. To restore the apparatus to normal, a number is dialled to bring L3 to the homing terminals. A similar arrangement but with only one dial is described in the Provisional Specification,

Title: Improvements in or relating to machines for making confections and applying handles thereto
IPC: A23G3/12
Filed: 1934-10-16
Abstract: 447,609. Moulding confectionery by rolling machines. PARKER - MEYERDENNIS CO., Dubuque, Iowa, U.S.A. Oct. 16, 1934, No. 29589. Convention date, Oct. 16, 1933. [Class 87 (ii)] A machine for making suckers and the like handle-equipped confections comprises confection-forming means, means for forming handles from a supply of pliant handle material, and means for connecting the handles to the confection. A batch of confection is supplied by a feeding trough 31, Fig. 1, to a pair of contacting moulding rolls 34, 35, Figs. 1 and 2 having complementary mould recesses 36, 37 in the peripheral walls. The recesses 36, 37 are both provided at one end with a slot 41, and as each piece of confection is formed at the contacting point of the rolls, a handle receiving recess is formed therein by a punch 49 which passes through the complementary slots 41 of the recesses. The punch 49 is slidably supported in a guide passage at the upper end of an arm 53 loosely mounted on the shaft 38 and is provided with a pair of depending projections 55 engaging a transverse arcuate segment 61 projecting from a bar 57 sliding in grooves on the bracket H. The bar 57, and hence the punch 49, is reciprocated by a driven disc 64 provided with a cam slot engaging a roller 62 on the bar. The punch 49 dwells at the end of its forward stroke, and is rocked about the shaft 38, to strip the confection from the upper roll 35 and cause it to remain in the recess in the lower roll 34, by an arm 67 connected to the arm 53 and having a roller 69 engaging a cam slot in a disc v on the drive shaft S. The pliant handle material 79 is fed by a pair of grooved rollers 81, Fig. 1, driven by pawl - and - ratchet mechanism, through a guide 134 and then through a pair of spaced guides 136, 137 and is cut into suitable lengths by a cam-operated knife adjacent the end of the guide 134. The cut length is engaged by one of a series of bars 185, Figs. 1 and 8, mounted in a rotatable disc 169, and is carried round through 180‹ before being inserted in the preformed confection P, the bar 185, as it is carried round by the disc, being retracted by the engagement of a roller 187 thereon with a cam slot 161 on a fixed disc 157, to form the material 79 into a loop. When the bar 185 reaches the end of the cam slot 161 and is opposite the confection P, it is engaged by a lever 235 and projected to insert the free ends of the handle into the recess in the confection. Inmediately after the insertion of the handle, the roll 34 contacts with a third roll 72 provided with mould recesses 75 to finally form the confection about the handle. The handle remains engaged with the bar 185 for a sufficient time to strip the confection from the roll 72, the bar being then further projected by the cam surface 165 to free the handle, whereupon the completed confection falls through a recess 77 on the base A onto a conveyer 78. Specification 424,192, [Group VI], is referred to.

Title: Control systems
IPC: G05B11/00
Filed: 1963-07-26
Abstract: 1,057,553. Automatic control. LOGIC SYSTEMS Inc. July 26, 1963 [Aug. 3, 1962], No.29673/63. Heading G3R. In a system for automatically regulating a manufacturing operation, signals corresponding to the magnitudes of a physical characteristic of successive articles subjected to the operation, are grouped into different size categories and, when the number in any group exceeds a number assigned to the group, a control signal is produced which adjusts the physical characteristic to a corresponding extent to restore it to a desired value. In Fig. 1 a web 10 is fed at constant speed by rolls 11, 12 and cut into lengths by rotary shears 15 driven by a variable speed motor 17. The length of web fed between each cut is measured by the number of electric pulses produced by a generator 19 coupled to a webdriven roll 9. Pulses corresponding to each cut length are stored by a counter 21 which is cleared by a pulse from a generator 20, applied through a delay unit 23, just after the cut occurs. Counter 21 produces an output on lead 27 when the length is close to the desired value, an output on lead 26 or 28 when the length is above or below first tolerance limits, and an output on lead 25 or 29 when the length is above or below second, greater, tolerance limits. Measurement of length at the moment of cut is ensured by applying the signals on leads 25-29 through "AND" gates 30-34 to which are applied the "cut" pulse from generator 20. The numbers of lengths falling within each of the five tolerance categories are counted in stores 36-40 which produce outputs when the numbers correspond to a Gaussian distribution e.g. 4 in the three closer tolerance categories and 2 in the two wider tolerance categories. Any output from store 37 or 39 after four errors in these categories is applied through an amplifier 42 or 43 to increase or decrease the speed of motor 17 as necessary to correct the length of subsequent cuts. Any output from store 36 or 40 after two greater errors is applied through an amplifier 41 or 44 to increase or decrease the speed of motor 17 to a greater extent. "NOT" gates 47, 48, 49 are provided so that store 36, 38 or 40 is reset if, during counting in that category, a length in another tolerance category occurs. Stores 37, 39 are reset by "OR" gates 62, 63, 64 whenever an output is produced by store 36, 37, 39 or 40. "OR" gates 65, 66 and "AND" gates 59, 60 ensure that if a signal representing a length above tolerance is followed by a signal representing a length below tolerance an immediate small correction is made through amplifier 42 or 43 unless four close-tolerance lengths intervene and cause store 38 to operate flip-flop circuits 54, 55 to prevent correction.

Filed: 1963-07-26
Abstract: 1,070,462. Radiator shutters. VARIVANE CO. Ltd. July 24, 1964 [July 26, 1963; Nov. 25, 1963], Nos. 29695/63 and 46417/63. Heading F4S. [Also in Division G1] A radiator shutter mechanism comprises pivoted shutters operated by a link 9, a spring 17 acting on the link 9 to close the shutters by way of a member (11, Fig. 7), a temperature responsive actuating element 10 to move the link 9 to open the shutters against the action of the spring 17, a second temperature responsive actuator, operating at a higher temperature than the first, to operate a release mechanism for the anchorage of the spring 17 and a second spring 21, weaker than the spring 17 acting on the link 9 to open the shutters when the release mechanism has been operated. The mechanism thus provides a " fail-safe " arrangement for the shutters. In one arrangement (Fig. 1) the shutters are operated from the link (9) by pivot rods (8) and the temperature responsive element (10) preferably a wax capsule element, is disposed in a chamber through which the cooling water which also passes through the radiator, flows. In Fig. 5 the upper end of the spring M is shown anchored to a pin 18 held in a housing 29 by a solenoid plunger 19 engaging a recess therein. In the event of failure of the element 10, the shutters 6 remain shut and the temperature of the cooling water rises. When it reaches a predetermined level the second temperature responsive element 25 actuates a switch 26 in the solenoid circuit to release the pin 18 and thus the tension in the spring 17. The shutters will then open under the action of the spring 21. In an alternative arrangement (Fig. 7) the spring (17) is secured to a pin (66) held by a ball (67) on a plunger (58). A second temperature responsive element acts on the plunger (58) so than when the temperature rises due to failure of the element (10) the plunger (58) is moved to bring a peripheral recess (59) thereon in line with the ball (67) thus releasing the pin (66). The connection between the plunger (58) and element (50) may be adjustable in length to adjust the temperature at which the pin (66) is released.

Title: A method of bleaching alkylated aryl sulphonic acids
IPC: C11D11/04
Filed: 1957-09-23
Abstract: The invention comprises a process for bleaching an alkylbenzene sulphonic acid in which the alkyl group contains 9-22 carbon atoms by admixing with water and hydrogen peroxide solution in such amounts that the resultant mixture contains not more than 20% by weight of water, based upon the sulphonic acid present, and hydrogen peroxide in an amount not exceeding that derivable from 5% by weight of the weight of the sulphonic acid, of a 30% solution thereof, and maintaining such mixture at a temperature not exceeding 60 DEG  C. until substantial bleaching has taken place.  Suitable alkylbenzenes are those obtained by the alkylation of benzene with decene-1, dodecene-1, pentadecene-1, octadecene-1, tetrapropylene, hexapropylene, pentabutylene and other olefine polyners.  The reactants should be agitated during the mixing to prevent local overheating of the sulphonic acid, and the hydrogen peroxide solution slowly added over a period of, e.g. 15-30 minutes or more at, e.g. 40-55 DEG  C.  The product may then be aged at room temperature for 12-24 hours or more prior to stabilization with from 1 to 2% by volume of a saturated solution of sodium bisulphite.  It is preferable to bleach the sulphonic acid whilst it is still relatively fresh and should it then be neutralized soon after the bleaching operation, for example, directly with sodium or potassium hydroxide, or by "dry" neutralization with sodium carbonate, sodium bicarbonate, sodium tripolyphosphate, tetrasodium pyrophosphate, sodium metasilicate, potassium tripolyphosphate or tetrapotassium pyrophosphate.  The "dry" neutralization may be preferably carried out by spraying the bleached sulphonic acid on to the agitated, finely-divided, anhydrous alkali metal salts and thereafter spraying a small amount of water on to the agitated mixture.  The water may also be added by a pouring or dripping process.  Additives such as sodium carboxymethyl cellulose, dyes and perfumes may also be present. Examples are given of the bleaching of dodecylbenzene sulphonic acid.  The process of the invention may also be carried out in a continuous manner.

IPC: G08C19/32
Filed: 1960-08-30
Abstract: 918,034. Transistor switching circuits. TELEPHONE MANUFACTURING CO. Ltd. Aug. 30, 1961 [Aug. 30, 1960], No. 29809/60. Class 40 (6). [Also in Group XXXVIII] A bi-stable trigger circuit provided with means for indicating the state of the circuit comprises a transistor 1 having the indicating means 3 connected in series therewith and a potential divider network connected across a voltage source and serving to bias the base electrode of the transistor, the potentialdivider comprising a two-state device, such as a cold-cathode discharge tube 2, which when it is conducting applies a bias potential to the transistor to cause it to conduct and operate the indicator. The indicator 3 is preferably a lamp but an electromechanical device may alternatively be used. Assuming that the device 2 is initially non-conducting, the application of a positive pulse at terminal 11 causes the device to conduct so that when the pulse finishes a negative bias is applied to the base of the transistor to render it conducting. In an arrangement comprising a plurality of bistable circuits, Fig. 2, the application of a positive pulse to one of the input terminals 17, 25, 26 causes the corresponding discharge tube 20, 15 to conduct, the voltage drop across resistor 12 so reducing the potential applied to the remaining tubes that any that are conducting are extinguished. Hence the indicator actuated indicates that terminal to which a positive pulse was most recently applied.
