Title: A process for the production of poly-bis-thiuram disulphides
Filed: 1954-01-14
Abstract: Poly - bis - thiuram disulphides of the formula (-S-CS-NR-Z-NR1-CS-S-)n are obtained by oxidizing in aqueous acid medium the bis-dithiocarbamates derived from primary and secondary diamines; R and R1 are hydrogen, alkyl or cycloalkyl, and Z is a divalent aliphatic or cycloaliphatic residue (derived, e.g., from ethane, pentane, hexane, decane, cyclohexane or cyclopentane); alternatively the group -NR-Z-NR1- may be a heterocyclic residue such as that of piperazine.  The reaction may be carried out by introducing an aqueous oxidizing agent into an aqueous bisdithiocarbamate at 0-10 DEG  C. and then acidifying, or by adding the aqueous bis-dithiocarbamate to an acid solution of the oxidizing agent.  In the examples ethylene diamine or piperazine is reacted with carbon disulphide and caustic soda and the resulting sodium bis-dithiocarbamate oxidized with hydrogen peroxide and sulphuric acid in the presence of air.  Halogens and hypochlorites are other suitable oxidizing agents.ALSO:Poly-bis-thiuram disulphides of the formula (-S-CS-NR-Z-NR1-CS-S-)n are obtained by oxidizing in aqueous acid medium the bis-dithiocarbamates derived from primary and secondary diamines; R and R1 are hydrogen, alkyl or cycloalkyl, and Z is a divalent aliphatic or cycloaliphatic residue (derived e.g. from ethane, pentane, hexane, decane, cyclohexane or cyclopentane); alternatively the group -NR-Z-NR1- may be a heterocyclic residue such as that of piperazine; the poly-bisthiuram disulphides may have a chain or ring structure.

Filed: 1970-01-12
Abstract: 1,267,390. Moulding double layered foam articles. MATTEL Inc. 12 Jan., 1970 [22 Jan., 1969], No. 1384/70. Heading B5A. [Also in Division C3]  Foamed plastics bodies with an outer foamed skin of higher density fused thereto are made by coating the inner walls of a mould with a first plastisol composition containing a blowing agent and activator, coating said first composition with a second plastisol composition containing sufficient blowing agent to release a larger amount of gas than the first composition and simultaneously heating both plastisols so that they are foamed. The plastisol is preferably polyvinyl chloride. In the embodiment shown for producing a doll, a layer of plastisol about 1/16 inch thick is rotationally cast or slush moulded in the mould 11 closed by cap 15 and the layer is heated to gel but not to foam the plastisol. The mould is then filled with the second composition which gels on the first layer due to residual heat, and, when the second layer has reached a thickness of #-“ inch, the remainder of the composition is emptied from the mould. The interior of the mould is then pressurized through tube 32 from a pressure source via valve 27 and the mould is heated to a temperature at which the blowing agent decomposes. A pressure release valve limits the pressure attained in the mould, thereby maintaining constant pressure therein. The mould is removed from the heater and simultaneously the pressure in the mould is slowly reduced so that the plastisol foams uniformly. After cooling the foamed article is removed from the mould by placing the mould in an enclosure, raising the pressure in the enclosure so that the foamed moulding is compressed and withdrawing the compressed moulding from the mould. The finished article preferably has a skin density of 40-70 lb/cu. ft. and a body density of about 10 lb/cu. ft.

Title: Improvements in or relating to electric or magnetic apparatus actuated by the passage of articles, such as bank-notes, through it
IPC: G07D7/00
Filed: 1943-12-23
Abstract: 595,764. Counting apparatus. KATZ, L. NAMENYI-, and FURZEHILL LABORATORIES, Ltd. Dec. 23, 1943, No. 1558/45. Divided out of 595,748. [Class 106 (i)] [Also in Group XXXVI] Articles such as banknotes are counted by registering electrical impulses produced by their passage through an impulse generator so arranged that impulses due to a group of more than one article combine to produce an impulse proportional to the number of articles in the group, which impulse correspondingly advances a registering device. In the apparatus shown, the arms of an A.C. bridge are formed by resistors 4, 5 and inductances 2, 3. The bridge is fed across one diagonal from an A.C. source 1, the other diagonal being connected to the input of an amplifier 6. The output of this amplifier is connected to a balanced modulator 7, which is also supplied with a signal input from the source 1. The output of the modulator is D.C. and is proportional to the out-of-balance voltage of the bridge and reverses in sign as the bridge output goes through the balance point. The output of the balanced modulator 7 is fed to a reactor valve 8 which is connected across the inductance arm 3 in such a manner as to tend to re-balance the bridge. The voltage derived at the input of the reactor valve 8 is nearly proportional to the original inductance change in the arm 3 and is supplied to an integrating device 9 which may comprise a resistance feeding into a condenser. Banknotes 12 containing metal strips are passed through the field of the inductance 3 and cause inductance changes proportional to the number of notes in each packet, thereby causing corresponding voltage changes at the input of the reactor valve 8. This voltage is integrated in the integrator 9, the voltage across the condenser of which is proportional to the number of notes passing together. The integrator condenser is arranged to be discharged whenever the signal input falls to zero by a discharging device 10. A counter 11, which is described in Specification 595,748, is operated by relays so that it discriminates between single, double and treble size impulses corresponding to the passage of one, two or three notes at a time.

IPC: D21H19/46
Filed: 1960-01-20
Abstract: 886,462. Cast-surface coated paper manufacture. MEAD CORPORATION. Jan. 20, 1960, No. 2083/60. Class 96. In the production of cast-surface, high gloss finish, mineral-coated paper, the mineral coating, whilst still mouldable is brought into contact with a chromium casting surface, e.g. of a belt or drum, which has been passivated, i.e. it in a state of inertness or non-reactivity to chemical reagents, produced preferably by mildly acidic oxidizing agents such as dilute nitric or acetic acid, which may be applied by a cloth, spraying, or flooding; the passivation facilitates release of the dried paper from the drum &c. Re-activation of the chrome surface by coating compositions of pH as high as 11 may be avoided by using a casting surface temperature just below that at which steam " blisters " are formed, so that drying is as rapid as possible. 1% of tributyl phosphate may be included in the coating composition to protect the chrome against reactivation. The invention may be used with re-wetted coated paper. Specification 838,180 is referred to.

Title: Target apparatus
IPC: F41G3/26
Filed: 1977-01-19
Abstract: 1520093 Toy guns; targets: shooting games MARVIN GLASS & ASSOCIATES 19 Jan 1977 [19 Feb 1976] 02096/77 Headings A6H and A6S [Also in Division F3] A beam of light is emitted from a dummy rifle 12 (Fig. 1) when fired at a target 20, and if the aim is acceptable the light is sensed by an element 24, which actuates an impeller to knock the target off a supporting frame 18. As shown, a plurality of targets 20 are supported on members 88 (Fig. 3) upstanding from an inclined shelf 22. An inclined track 38 (Fig. 2) runs beneath the shelf and supports a carriage 34 guided by rollers 36/42/50. The carriage mounts batteries powering a phototransistor supported in a shield 165, and powers a motor 100 actuable to rotate an arm 116 clockwise to pivot an arm 102 about an axis 106, and then to open an electrical switch 134/132. The carriage 34 is normally held beneath a target 20 by a spring biased catch 140 engaging a pivoted plate 82 supported on the shaft 22, and which can be pivoted to a position in which a tip 76 knocks over the target 20, and in which the catch 140 is released to allow the carriage to roll down the inclined track 38. Operation. The carriage 34 is moved by a handle 60 to a position at the top of the inclined track 38, where it is held in place beneath the leftmost (in Fig. 1) target by the catch 140 (Fig. 3). If the rifle is correctly aimed at the target 20, a light beam passes through the adjacent frame aperture 24 to fall on the phototransistor 162 (Fig. 14). This conducts electricity from the batteries 170 to apply a voltage to a rectifier 168, which fires through the normally closed switch 134/ 132 (see also .Fig. 3) to operate the motor 100. The motor rotates the arm 116 clockwise to pivot arm 102, which thereby pushes a shaft 78 and the supported plate 82 to the right. A plate stop is thus freed from contact with the inclined shelf 22, and the plate 82 is rotated by a spring 84 so that its tip 76 knocks the target 20 off its supporting members 88 with a bang. The rotation also frees catch 140, and the carriage 34 (with its catch 140, arm 116 and motor 100) rolls down the track 38 until recaught beneath the next target. Further rotation of the motor 100 arm 116 opens the switch 134/132 to stop the motor, deenergise the rectifier 168 and so reset the sensing circuit. The operation is repeated for successive targets. Dummy Rifle. When an arm 200 (Fig. 10) is pivoted about an axis 202, a catch 206 on a likewise pivoted member 204 engages a notch 208 on an arm 210, to hold a rod 222 in a rightmost position. The rod 222 pulls a piston 224 to the right. The trigger 220 lifts arm 210 to free member 204 and rod 222, so that a spring 236 pushes the piston 224 back to the left to compress trapped air, which simulates a recoil. The air escapes into a second cylinder 242 to push a second biased piston and attached contact 254 to the right. The contact operates a bulb 260 from batteries 190 in the stock, for momentary light emission through a lens 262. A lever 270 is provided for testing the bulb. A viewfinder 198 and sight are provided.
