Title: Improvements in self winding reel
IPC: G01B3/10
Filed: 1951-08-13
Abstract: 701,275. Measures of length. MASTER RULE MANUFACTURING CO.. Inc. Aug. 13, 1951 [Aug. 22, 1950], No. 19035/51. Class 106, (2). [Also in Group XXX] One end of a measuring-tape T is secured to a reel 8 rotatable in a support and rotatably supporting two drums 12 and 14 between which is connected a pre-set spring 19 normally wound on one of the drums 12, a planet pinion 15 secured to one of the drums 14 meshing with a sun pinion 16 fixed to the support. The reel is pivoted between two flanged discs 1, 2, the peripheries of which are joined by inner and outer ring members to form a housing. When the tape is drawn out by a leader L, it passes between rollers 7 mounted in the housing, and the reel 8 and consequently the drum 14 are rotated. The spring 19 is thus wound onto the drum, being flared in the reverse direction to its set. When the tape is released, the spring winds itself back on to the drum 12, thereby rotating the drum 14 and the reel 8. A brake drum 17 secured to the reel 8 is normally engaged by brake shoes on arms 20 which are mounted on pivots 22 and urged outwardly by springs 24. To release the brake, a pin 25 is pushed inwardly by a button 27 against a spring 28, a cam surface 26 on the pin rocking extensions 23 of the arms 20. In an alternative construction of brake, spring- loaded brake shoes normally act on the periphery of the reel 8 and are disengaged by a button mounted on the edge of the housing. The inner end of the tape is shaped so as to be readily detachable from a leader formed with a loop for engagement over a stud 18 carried by the reel and with a hole by which its end can be held outside the housing.

Abstract: 1,004,778. Electric totalizators. ELECTRONIC ASSISTANCE CORPORATION. May 18, 1962 [May 19, 1961], No. 19293/62. Heading G4A. A bet is recorded by punching a card and entering the card at a reading station 10. The reading stations are connected in groups to hubs 12 which are effectively buffer stores. Bets recorded at stations connected to a hub are punched on to paper tape and are read into a buffer store having a capacity of five bets. The buffers are cyclically scanned and their contents transferred to a magnetic drum comprising bet storage 14. Odds are continuously calculated in known manner and the results displayed on a board 22. Betting on a particular race is stopped by actuation of manual controls 24 which prevent the depression of card punching keys. At the conclusion of a race the manual controls are operated to cause the winner and dividends to be entered from the computer into the store 26, which may be part of the magnetic drum. To claim winnings the punched card is presented at a cashier station 17 where it is identified by the hub which transmitted the bet and the race for which it is valid. This identification is made by a card reader which calls for all bets made on the race to be read from the drum 14 to the cashier station. The bets are compared automatically with the remaining information on the card and when the bet corresponding to the card is found information in store 26 is made available at the cashier station which for this purpose is multiplexed with the other stations 17. At the same time the card is transferred to a receptacle and a mark is made on the drum against the bet to indicate that payout has been made. Payout may be automatic by means of a change-giving machine. Uncollected winning bets are transferred at the end of the day to more permanent storage 32, which may be magnetic tape, and winning cards are presented at special stations for payment on later occasions. Specification 1,004,779 is referred to.

Abstract: 412,774. Valve amplifying circuits. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. July 7, 1933, No. 19336. Convention date, July 27, 1932. [Class 40 (v).] In a high-frequency coupling coil wound with - a wire sub-divided into a number of conductors, for example a stranded wire, one or more of these conductors are connected in parallel with the others only over part of their length, the other part forming a separate coil for connection in another circuit. Fig. 3 shows the connections for coupling two valves 5, 6, the coil being shown in Fig. 5 unwound so that the conductors lie in one plane. The coil L1 forming, with a condenser C, a tuned circuit connected to the grid of the valve 6 is wound with a stranded wire containing, for example, 20 conductors. At a determined point a number of these conductors, for example two, are cut and led to the exterior. The other conductors, i.e. the 20 conductors arriving at this point and the 18 conductors leading away from it, are connected to one another. The two conductors which are taken to the exterior form a coil L2 which is connected in the anode circuit of the valve 5. The points 8, 7 may be connected by a condenser Ck of sufficiently high capacity to ensure that they have the same high-frequency potential at all frequencies. For very high frequencies, however, the mutual capacity between the conductors is sufficient. More than two coupled circuits may be formed by splitting off a certain number of conductors at determined points of the coupling element so that each group forms a coil which may be included in a circuit.

Title: Improvements in or relating to electrically-operated burglar alarm systems
IPC: G08B13/22
Filed: 1923-07-31
Abstract: 223,674. Draper, W., and Fairlie, T. July 31, 1923. Burglar alarms.-A burglar alarm circuit is worked by current from the lighting mains and is arraned so that when contacts arranged in the floor are trodden on, an audible alarm is sounded, a visible signal outside the building is illuminated, and part or all the lights in the building are lit up. The figure shows the arrangement of the circuit. A, A<1> are the lighting mains and in one of them, A, is an automatic switch 1. A shunt circuit B is connected across the mains on the supply side of the contact 1. This circuit contains the floor, or door or window alarm contacts B<1> in parallel, and an electromagnet B<2> the core B<3> of which is connected to the blade 1 of the switch 1. A push button switch B<4> is incorporated for arbitrarily closing the shunt circuit. A bypath C containing an auxiliary switch 2 is connected to the switch 1 so that they will open and close together is incorporated to maintain the circuit B when the contacts B<1> have been released. The shunt circuit also contains a setting-switch B<5> which, when opened, renders the shunt circuit inoperative. To set the circuits for giving an alarm the switch B<5> is closed and the switch B<4> opened. An intruder treading on contacts B<1> causes a current to flow from the positive main A through the solenoid B<2>, through the contact B<1> and through the switch B<5> to the negative main A<1>. The momentary " making " of the contact B<1> by a person treading on the floor where the contacts B<1> are arranged, and the passage of the current, results in the attraction of the core B<3> of the solenoid B<2> and the closing of the switches 1, 2. The closing of the switch 2 maintains the current flowing through the solenoid B' when the contacts B' are broken, so maintaining the core B<3> in position to keep the switch 1 closed and causing all the lights in the building to be illuminated if their individual switches are " on." Connected also to the core B<3> are switch blades 3, 4 in circuits D and E respectively, also connected to the mains A, AT. Hand switches D<1>, E<1> can put these circuits into, or out of, operation. Simultaneously with the closing of the switches 1 and 2, the switches 3 and 4 are closed, completing the circuits D and E and causing a visible signal 6 to be illuminated at some prominent place on the outside of the building, and causing an audible alarm such as a horn 7 to sound. The alarm contacts B<1> comprise recesses in the floor containing strips of metal and closed by lids having on their underside strips of metal at right angles to the strips in the recesses. The lids are held flush with the floor by springs capable of bearing the weight of a cat or dog, but not that of a man. The switch blades 1, 2, 3, 4 may be clamped at intervals on a rotary shaft 28, Fig. 4, which is rocked when the armature 29 is attracted by the magnet 23.

Filed: 1956-06-25
Abstract: 835,744. Electrodialysis. NEDERLANDSE CENTRALE ORGANISATIE VOOR. TOEGEPAST NATUURWETENSCHAPPELIJK ONDERZOEK. June 25, 1956 [July 4, 1955], No. 19646/56. Class 41. In a process for electrodialysing liquids in which the liquid is led through an apparatus comprising at least one pair of spaced membranes of which one is anion selectively permeable and the other is cation selectively permeable and conduit means are provided for introducing the liquid to and withdrawing it from the compartment formed between the membranes, means being provided for contacting the outer surfaces of the membranes with a rinsing liquid and for passing direct electric current through the membranes and compartment, the liquid is passed through at a velocity which is higher than the velocity V given by the formula The quantities, except for K, n, depend on the dimensions of the compartment, on the liquid being electrodialysed, and on the electric current, and are defined in the Specification. To calculate K, n for a particular apparatus and liquid, it is necessary to perform a number of experiments, varying one of the quantities, e.g. i, the current density, and passing the liquid through the apparatus at correspondingly different critical velocities. The values of K, n, are approximately constant, although n varies slightly with the liquid employed, and K with different apparatus, liquids and current densities. In a series of experiments with an NaCl solution, n=0.8, and K=values ranging from 0.34 to 0.46. In the experiments, V is discovered by calculating the voltage Á without polarization, i.e. at infinite flow velocity (Á= #R.i, where R=the combined resistances of the liquid and the membranes multiplied by the area of a membrane, and adjusting the velocity until the applied voltage=1.25Á. The flow velocity then = V, and by substitution K, n may be found. Specifications 637,425, 682,703 and 736,888 are referred to.

Title: Improvements in or relating to processes and apparatus for the production of coloured self-adhesive plates from aluminium foil
IPC: B05D1/32
Filed: 1957-06-21
Abstract: 850,934. Printing processes. KELLER, E. June 21, 1957 [Nov. 5, 1956], No. 19704/57. Class 100(2) A process for the production of aluminium foil plates which have a self-adhesive layer on the back is characterised in that an electrolytically oxidised aluminium foil strip which has been uniformly coated with a coloured layer is provided in those regions which are to appear coloured in the finished plate with a greasy substance serving as a protective layer, whereafter the aluminium strip is passed in succession through an etching bath for removing colour in the non-greased portions, through a washing bath, through a de-greasing bath with a mechanical cleaner to remove the greasy substance, through a subsequent cleaning bath and finally to a drying tunnel, after leaving which the strip has applied to it an adhesive foil and is finally wound on to a roll. The strip is provided with the greasy resist by printing on the strip with a printing plate having printing areas corresponding to the areas A-I and K-Q on the strip which it is desired to colour and which form the foil plates to be made. The strip is thus printed with the resist, e.g. greasy ink, continuously and the resulting roll mounted at one end of the etching, washing, de-greasing and drying apparatus. All the baths are provided with compressed air lines for forcing air through the baths and thus keeping them agitated. The mechanical cleaner comprises opposed horizontal surface brushes and in the subsequent cleaning bath an ultrasonic transmitter is included to complete the cleaning. The drying tunnel includes infra red radiators facing both sides of the strip and a fan mounted in the central part of the tunnel for drawing air from the atmosphere and conveying it to both ends of the tunnel.
Patent GB-615628-A (GB)
Title: Improvements in or relating to the preparation of beta-mercaptovaline and metal salts thereof
Filed: 1945-08-01
Abstract: An alkali-metal salt of b -mercaptovaline is prepared by treating b -benzyl mercaptovaline with an alkali metal in an anhydrous solvent, e.g. liquid ammonia or an alcohol, to remove the b -benzyl group by reductive cleavage, thus b -benzyl mercaptovaline is reduced by means of metallic sodium in liquid ammonia to yield the disodium salt of b -mercaptovaline and dibenzyl.  Other reductive means which may be employed include metallic sodium in anhydrous butanol.  The alkali metal salt of b -mercaptovaline on treatment with ammonium chloride yields b -mercaptovaline, thus the product remaining after the reduction with sodium in liquid ammonia is treated with ammonium chloride and after removing the excess ammonia the free base is obtained mixed with sodium and ammonium chlorides.  The b -mercaptovaline is preferably isolated as a salt with an acid, e.g. hydrochloric, sulphuric, acetic, or phosphoric acid from which the free base may be obtained by neutralization with an alkali.  The salts of sodium, potassium, calcium, magnesium, ammonia, pyridine, morpholine and diethanolamine may be prepared by neutralizing the carboxylic acid group of the free base.  Esters may also be prepared by allowing the product to stand in an alcohol such as methyl, ethyl or n-propyl alcohols, saturated with hydrogen chloride. Beta-mercaptovaline will react with heavy metals, e.g. copper, to form complex salts even at low concentrations of the metal ion and is therefore useful as a metal deactivator.  In an example, metallic sodium is added to a solution of b -benzyl mercaptovaline in liquid ammonia until a blue colour persisting for at least 20 minutes is produced.  An equivalent amount of ammonium chloride is then added and excess ammonia is removed. The residue is slurried up in methanol and dry hydrogen chloride passed in until the reaction mixture is acid to congo red.  The mixture is filtered to remove sodium and ammonium chlorides and then evaporated under reduced pressure to obtain b -mercaptovaline hydrochloride.  A sample prepared as follows has been furnished under Sect. 2 (5): metallic potassium is added to a solution of beta-benzyl mercaptovaline until a blue colour persisting for at least 5 minutes is obtained and ammonium chloride then added.  Excess ammonia is removed and the residue slurried in ethanol and made acid with concentrated hydrochloric acid.  The mixture is filtered, the filtrate evaporated to dryness and redissolved in alcohol, after refiltering the solution diethylamine is added and the mercaptovaline filtered off.  The beta-benzyl mercaptovaline starting material may be prepared as described in Specification 609,722.
