Title: Adhesive films
IPC: C09J161/06
Filed: 1969-07-01
Abstract: 1,242,658. Honeycomb laminates. CHISSO CORP. 1 July, 1969 [19 July, 1968; 22 Oct., 1968], No. 33092/69. Heading B5N. [Also in Divisions B2 and C3] An adhesive film, suitable for use in the manufacture of honeycomb sandwich structures, is produced by impregnating a porous web substrate, e.g. a glass fibre fabric, paper, cloth or mat of synthetic fibres, non-woven fabric, victorian lawn or gauze, with a resin solution containing a phenol-formaldehyde resin and polyethylene glycol and/or polypropylene glycol, coating at least one surface of the impregnated substrate with a powdered thermoplastic resin and then drying at a temperature below the curing temperature of the phenol-formaldehyde resin, e.g. at below 80‹ C. for 2-3 minutes. The polyethylene glycol or polypropylene glycol, which may be used in an amount of 1-100 parts per 100 parts by weight of phenol formaldehyde resin, may have a molecular weight of 200-4000. The solvent used in the resin solution may be methanol, ethanol, chloroform, acetone, benzene or dichloroethane. The resin solution may also contain an acid hardening catalyst for the phenol-formaldehyde resin, e.g. toluene, xylene or benzene sulphonic acid, in an amount of 1-10 parts per 100 parts by weight of the mixture of phenol-formaldehyde resin and polyethylene glycol and/or polypropylene glycol, and sufficient of an alkaline substance, e.g. sodium or potassium hydroxide or an amine, to adjust the pH of the solution to 3-6. The thermoplastic resin which may have a particle size of less than 42 (Tyler) mesh may be polyvinyl formal, acetal, butyral, isobutyral, acetate or alcohol, and may be used in an amount of at least 40 parts per 100 parts by weight of the mixture of phenol-formaldehyde resin and polyethylene glycol and/or polypropylene glycol. The adhesive film may be covered for storage with strippable films or sheets, e.g. polyolefin films, regenerated cellulose films or release papers. Honeycomb sandwich structures may be produced by placing the adhesive films between the honeycomb core which may be of paper and surface sheets, e.g. of aluminium, and then applying heat and pressure.

IPC: G05B19/02
Filed: 1970-07-08
Abstract: 1,263,676. Motor controllers; actuation. METZENAUER & JUNG G.m.b.H. 8 July, 1970, No. 33145/70. Heading H1N. In a cam-actuated star-delta switch for a three-phase motor, a cam 9, Fig. 1, driven through gears 2, 3, 5, 6 from a pilot motor 1 determines the closure time for star-connected contacts 12, 12II, 12 IV but on opening of the contacts when lever 10 drops, the immediate closure of the delta-connected contacts 12I, 12III, 12V is retarded by a time delay catch system 17, 19 which prevents the lever 10 from dropping to its full extent. The catch comprises a spring-loaded plate 17 which falls on to a roller 19 of a drive shaft 9 whereby the plate 17 is rotatably driven by roller 19 for a preset time before it falls clear of the roller 19 thereby determining the interval between opening of the star connection and closing of the delta connection. The contacts may be directly coupled in the circuit of the motor to be controlled or may control intermediate relays. In a modification, Fig. 4 (not shown), the star-delta contacts 12-12V are not under control of the cam 9, the plate 17 being arranged to swing a change-over contact controlling a pair of intermediate relays for the star and delta systems. Further cams 8, 9a operating switch contacts 81, 82, 83 control the starting and stopping of the pilot motor 1. A slipping clutch 7c permits relative manual adjustment of the starting positions of cams 9 and 9a to that of cam 8 by control knob 7d whereby the closure time for the star-connection system may be preset.

Title: Telecommunications systems
IPC: H04L12/00
Filed: 1972-07-20
Abstract: 1395413 Automatic exchange systems SIEMENS AG 20 July 1972 [9 Sept 1971] 34008/72 Heading H4K In a telecommunication system, signals between data substations and the exchange in one or other direction are acknowledged by the receiving end only after a delay and the transmitting end is arranged to indicate that a double or undesirable connection has occured if an acknowledgement is received too quickly. The invention deals with avoiding errors that can occur when the exchange employs the same tone for "calling tone" and for "proceed to send" tone and the substations if idle automatically respond to an incoming call if ready to receive and employ a single tone for "waiting to transmit" (in connection with an outgoing call), and for "ready to receive" (in connection with an incoming call), the transmission delays being such that transmission of calling tone may be initiated after a substation has initiated a call but before that call has been detected at the exchange, or a call may be initiated after the exchange has initiated transmission of a calling signal and before that calling signal has reached the substation, the signals in the two directions in each case relating to different calls but being interpreted as relating to the same call. The substations may be directly connected to the exchange or connected thereto by one or more concentrators. The figure shows a substation signalling circuit DSt connected to an exchange circuit EDs. As shown the acknowledgement delay is effected at the subscriber end DSt, delay t having a value at least equal to the difference between the maximum and minimum transmission time between any substation and the exchange. If the substation goes off-hook inputs K6 and K8 go to "1" potential and if it is ready to receive or transmit input K7 goes to "0" poential. If no signal is being received at E2, the other input to NAND gate G6 is zero and NAND gate G8 enables S2 to transmit calling tone to receiver El. As a counter Z is at zero count at this time providing a "1" output at a2 gate G5 responds producing a new call "0" potential at K5. If prior to such new call detection a new incoming call is detected for the subscriber, calling tone is transmitted from S1 to E2 and a counter Z is started. If the substation is free and ready to receive then after the delay determined by t, acknowledgement tone is transmitted from S2 to El. The lower counts of the counter enable a line a1 and if a tone is received at this time it cannot be a ready to receive tone and the output of NAND gate G4 goes to zero indicating that signals from two separate calls are involved, the exchange responding by sending engaged tone to the distant station and accepting the outgoing call. The upper counts of the counter enable a line a2 and if a tone is received at this time the output of NAND gate G4 goes to zero indicating that the substation is free and ready to receive.
