Title: Wirebound box-making machine
IPC: B27M3/36
Filed: 1963-04-17
Abstract: 992,870. Wirebound box-making machine. STAPLING MACHINES CO. April 17, 1963 [May 7, 1962], No. 15036/63. Heading B5D. [Also in Division B8] In a machine for making blanks (Fig. 7) for wirebound boxes at least one intermediate binding wire B does not extend along the complete length of the blank. Properly aligned sections of a blank maintained in spaced relation by members. N (Fig. 4) clamped to a conveyer P are moved in the direction R towards a stapling unit K (Fig. 1). A trip lug 166 (Fig. 4) on the leading member N 1  contacts a finger 148 of a switch unit 132 which causes an exhaust valve 130 (Fig. 1) to remove pressure from an air cylinder 64 thus allowing springs 70 to retract a cutting member 48 into its upper position. The air flow from another cylinder 36 is also cut off permitting a spring 40 to move lever 22 upwardly and thus cause feed wheels 16 and 18 to engage and commence feeding of the wire. The leading end of a box blank and the wire reach the stapling unit K simultaneously and staples are driven astride the wire B (Fig. 7). The machine is arranged so that when the desired length of wire has been fed, the lug 166 (Fig. 4) contacts a finger 149 of a second switch unit 134 which permits air to flow to cylinders 36 and 64 (Fig. 1) thus causing the feeding of the wire to stop and the cutting member 48 to descend and sever the wire. The stapling unit is controlled by the mechanism shown in Fig. 6. A chain 180 is driven in synchronism with the conveyers P and start and stop blocks 174, 176 respectively fixed thereto contact a finger 182 which through a switch 188 either de-energizes or energizes an air valve 192 (Fig. 1) to allow air to be released from or to flow into a cylinder 194 and thus cause a roller 202 to either commence or interrupt feeding of the wire B to the stapling unit K.

Title: Improvements in the manufacture of chlorinated polythenes
IPC: C08F8/20
Filed: 1941-11-26
Abstract: In the preparation of chlorinated polythenes by subjecting solid or semi-solid polymers of ethylene to the action of chlorine in the presence of an inert liquid medium, the reaction zone is illuminated with sunlight, or with artificial light preferably rich in green and yellow light, the reaction is carried out in the presence of not more than a small amount of oxygen, and at least part of the heat evolved by the reaction is removed.  A batch or continuous process may be used, the bulk of the air being first displaced from the reaction vessel by a stream of a gas which is substantially free from oxygen. The inert liquid medium may be a solvent, such as carbon tetrachloride, or a non-solvent, such as water, in which the polymer is suspended in a finely-divided state; other liquids which are not appreciably chlorinated during the reaction, e.g. trichloracetic acid, chloroform, hexachlorethane or hexachlorbenzene, may be used. The air may be removed from the liquid medium by boiling, followed by cooling in a stream of gas free from molecular oxygen, or by distilling in the absence of air.  The chlorine employed may be free from oxygen, or may contain up to 0.2 per cent of oxygen by volume. The illumination may be sunlight or a daylight fluorescent tube. The hydrochloric acid evolved during the reaction may be removed, and the product may be separated by passing the reaction mixture into hot water and distilling off the solvent, leaving the product floating on the water, or by adding a liquid, e.g. alcohol, which is miscible with the solvent to give a liquid which is a non-solvent for the product.  In an example, polymerized ethylene of molecular weight 10,000, is dissolved in hot carbon tetrachloride, the solution cooled, and the air displaced from the vessel by a stream of carbon dioxide.  Chlorine containing 0.1 per cent of oxygen is then passed in while stirring, and the reaction zone illuminated with a 1000 C.P. light rich in wave-lengths of 4785  ., the temperature being controlled by cooling water to between 20 DEG  and 35 DEG  C.  The hydrochloric acid is removed as evolved, and the product is separated by pouring the reaction mixture into hot water and distilling off the carbon tetrachloride.  The chlorinated polymers may be shaped by extrusion or pressure moulding, or may be applied in the form of paste, dispersion, emulsion or solution to a mould or base. Specification 481,515 is referred to.

Title: Improvements relating to telegraphic signal amplification
IPC: H04L25/06
Filed: 1926-06-19
Abstract: 277,740. Wood, K.. L., and Eastern Telegraph Co., Ltd., June 19, 1926, Addition to 246,531. Systems employing non-contact making relays.- In a system as claimed in the parent Specification movements effected by the received signals vary a capacity to disturb the balance of the system in relation to the recording instrument. In one arrangement, Fig. 1, the receiving coil 4 carries a metal plate 2 disposed between fixed metal plates 1, 3 connected to the grids of thermionic valves 5, 6 respectively. The anodes of the valves are connected through the recording instrument 10, and the anode battery 9 is connected to the junction of resistances 7, 8 of which the other ends are connected through the instrument 10. The local alternating current source 11 is connected between the plate 2 and either pole of the filament heating battery b. The system is balanced when no signals are being received, and with the source 11 disconnected, by adjustment of the filament rheostats or of one of the resistances 7, 8. The source 11 is then connected and the plates 1, 3 are adjusted in relation to the plate 2 to restore the balance. The receipt of a signal moves the plate 2 nearer to one or other of the plates 1, 3, thus disturbing the balance and causing a current to traverse the instrument 10. To enable the degree of amplification to be adjusted two additional infinitely-variable condensers may be connected in series across the source 11 with the plate 2 and the valves 6 connected across one condenser only. In a modification, Fig. 3, the plates 1 - - 3 are replaced by coils 13 - - 15, thus enabling an electro-magnetic effect to be utilized in addition to the electrostatic effect between the coils. Each coil 13 - - 15 is connected to one plate of a condenser 16 - - 18 respectively, and the other plates of the condensers are connected to the source 11 and to the valve filaments. In another arrangement, Fig. 2, the fixed plates 1, 3 are connected to opposite apices 33, 34 respectively of a bridge supplied from the alternating current source 11, and the apex f and the plate 2 are connected through the primary 35 of a transformer A provided with a series condenser 36 and a shunt condenser 37. The secondary 38, shunted by a condenser 39, is connected through a condenser 41 to the primary 40 of a transformer B, of which the secondary 42, shunted by a condenser 43, is connected with a grid biasing battery 45 in the input of a rectifying valve 44. The condensers 36, 37, 39, 41, 43 and the coupling of the transformer A are adjustable for eliminating undesired frequencies.
