Title: Method and apparatus for insertion of electrical contacts into electrical connectors
IPC: H01R43/00
Filed: 1969-07-23
Abstract: 1,244,059. Inserting electrical contact pins and sockets; contact insertion tools. HUGHES AIRCRAFT CO. 23 July, 1969 [19 Aug., 1968], No. 37123/69. Headings B4C and B4W. [Also in Division H2] Electrical contacts in the form of pins or sockets crimped on to wires are gripped by a retaining device 44 on the end of an elongated portion 43 of a tool 40 and pulled into an aperture, e.g. 101, of a connector body 100, the retaining device 44 being actuated by a trigger 32 on the tool 40. The contacts may be numbered corresponding to numbering of the apertures in the connector body, and these apertures may have sealing members 102 with contact engaging ribs. For inserting the electrical contact pins 111, the retaining device 44 comprises a collet 13, Fig. 3, slidably mounted within a housing 14 and having an enlarged end portion 133 with a bevelled surface 139 engaging a similar surface 38 on the housing 14. The pin portion of the contact may be inserted in the collet 13, and when the collet is retracted by pulling a wire 15 having an enlarged portion 115 engaging with a shoulder 236 on the collet, slots 138 in the collet allows it to contract to grip the pin contacts. For inserting electrical contact sockets, the retaining device comprises a cylinder 22, Fig. 5, having bevelled edges 29, 30 which engage with similar edges 16, 24 on bushes 17, 18, the bush 17 being movable relative to the bush 18, the movement being limited in one direction by a stop 23. The cylinder 22 has a longitudinal slot (not shown) and hence expands outwardly when the bush 17 is moved towards the bush 18 by a wire 21, to which it is attached in a similar fashion to the wire 15 and collet 13. The cylinder 22 is thus inserted in the contact socket and expanded to grip the socket. The other end of either the wire 15 or 21 is held in a plunger 59, Fig. 6, partially contained in a housing 58 having a threaded portion 65 to adjust the tension in the wire. The plunger 59 is reciprocated against the pressure of a spring 60 by the rocking of a trigger 32 about a pivot 146, Fig. 7, through a " dumbell " 90 having each end engaged in recesses in the plunger and trigger respectively. In the fully retracted position of the plunger, i.e. when the contact is gripped to draw it into the aperture in the connecting body, the trigger and hence the dumbell is in its raised position. To release the contact the trigger is depressed through the position of maximum pressure in the spring 60 and is stopped at a position just below this. The movements of the trigger 32 are limited by a peg 148 abutting the perimeter of an aperture 145 in the trigger. In a further embodiment, the dumbell 90 may be dispensed with, and a trigger 177 rockable about a pivot 196 may be provided having cam surfaces 197, 178, which engage a roller 198 mounted on the plunger (not numbered). The tool as shown in Fig. 11 is in the retracted gripping position and forward movement of the trigger will release the contact.

Title: Treatment of wood to reduce its combustibility and its tendency to rot
Inventor: LEWER HANS
IPC: B27K3/18
Filed: 1969-07-25
Abstract: 1,268,691. Rot proofing treatment of wood. CHEMISCHE FABRIK KALK G.m.b.H. 25 July, 1969 [27 July, 1968], No. 37471/69. Heading A5E. [Also in Division D1] The combustibility of wood and its tendency to rot is decreased by applying to the surface of the wood solid calcium chloride, solid magnesium chloride or a mixture thereof in powder or granular form. These chlorides may be blown onto the wood to be treated by means of compressed air, quantities of 0.15-0.6 kg/m<SP>2</SP> being suitable. Adherence is most marked if the particle size is less than lmm in over 80% by weight and is less than 0.3mm in over 60%. Since the chlorides are hygroscopic they rapidly attract moisture and form a solution and the penetration of this solution into the wood is encouraged if a wetting agent is added before application. The wetting agent may be present in an amount of 0.5-10% by weight and the one exemplified is nonylphenol-polyglycol ether. The invention finds particular application in wooden mine supports.

Title: Improvements in subscribers' line circuits for automatic exchange systems
Inventor: WARMAN BLOOMFIELD JAMES
IPC: H04M1/738
Filed: 1957-12-02
Abstract: 888,356. Automatic exchange systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 25, 1958 [Dec. 2, 1957], No. 37484/57. Class 40 (4). Ina subscriber's line circuit comprising a transistor TL which is responsive to the subscriber's loop, the base is connected to one line wire, and the emitter and collector are connected to the private wires on the line-finder and final selector sides, respectively. When a subscriber's loop is closed the base potential of TL is depressed and current flows from source V1 ( - 10 v.) via the emitter and base of transistor TS, rectifier MR and the emitter and collector of TL. This lowers the potential of wire 3 somewhat below V3 (which in the preferred embodiment also = - 10 v.). The potential of the wire 4 becomes equal to that of wire 3 and is greater than V4 ( - 15 v. ) so that the transistor TFS cannot conduct if a final selector FS tests the line, so that the line is thus busied thereto. Conduction of transistor TS causes the finder start relay ST to operate to initiate hunting by a finder LF. When the P-wiper connects with wires 3 of busy, or non-calling lines it takes up potential higher than V3 and TLF does not conduct. When the calling line is encountered, however, TLF conducts to operate a stopcircuit SPA for the finder. This operates contact ha to put full earth on wire 3 to busy the circuit to other line finders. This causes TL to conduct so that this busy earth is also applied to the private wire on the final selector side. If the line is wanted by a final selector FS, when the latter reaches the line potential V4 ( - 15 v.) is applied to wire 7 via a marking contact (not shown). If the line is busy the P-wiper encounters potential higher than V4 and the selector does not stop. If the line is free the P-wiper encounters potential V2 ( - 20 v.) which being less than V4 causes the transistor TFS to operate the stop circuit SPB. The latter operates hb to apply full busy earth to the private wire 4 which causes transistor TL to conduct in the reverse direction so that the busy earth also appears on the private wire 3.

Title: Coincidence circuit arrangement
Inventor: THOMPSON MALCOLM PETER
IPC: G06F7/02
Filed: 1961-10-19
Abstract: 1,025,885. Coincidence circuits. RANKBUSH MURPHY Ltd. Oct. 19, 1962, No. 37500/61. Heading H3T. A coincidence-detecting circuit comprises means for combining the two input signals to form a three-state signal which is applied in parallel to two two-state devices whose outputs are connected via two diodes of like polarity to a common output terminal. In Fig. 1 the inputs IN1 and IN2 from the corresponding stages of two counters (Fig. 3, not shown) are combined and fed in parallel to two transistors 9, 10 via an emitter follower 5. Transistor 9 has in its emitter circuit a Zener diode 11 which becomes conductive at a voltage which is between the first extreme value of the threestate signal and the intermediate value. Transistor 10 is coupled via Zener diode 16 to a further transistor 15, the rating of the diode being such that it conducts between the intermediate and the second extreme value of the three-state signal. The outputs B, D of the circuits are fed via diodes 20, 21 to a common output terminal which is resistively connected to negative supply. The diodes 20, 21 are joined to the collectors of transistors 9, 15 and will be cut off when a non-coincident state exists, so that the output will be the negative supply voltage. When coincidence exists at either the first or second extreme value the output will be the voltage at the collector of the conducting transistor 9 or 15. A number of such circuits are used in a computer (Fig. 4, not shown) and connected via diodes to a trigger circuit which gives an output when all the diodes are cut off, i.e. when all the stages of the two input counters are in similar states.
