Title: Slotted plate connector
IPC: H01R4/24
Filed: 1973-07-23
Abstract: 1440813 Terminals; two-part couplings AMP Inc 23 July 1973 [3 Aug 1972] 35073/73 Heading H2E A stamped and formed V-shaped plate has two slots 12, 14 parallel to the light 8 and normal to the respective plate portions 4,5. Forcing a wire 24 into the slots by means of a tool 26 tends to twist the plate portions 4, 5 perpendicular to the wire and thus bends them towards one another (Fig. 6) to provide resilient contact pressure. The edges of one slot 12 cut through the insulation and into the core 22. The other slot 14 is wider and its edges cut only partway into the insulation to provide strain relief. Kinks 20 tend to straighten, thus bending the plate portions 4, 5 (Figs 7 and 8, not shown), to contribute further to contact pressure. Forming the plate with the kinks 20 also allows the slots 12, 14 to be made very narrow for fine wires if required. A portion 10 is fitted in a hole 11 in a p.c. board 13 and soldered to a conductor on the underside. Two terminals formed integrally in a Z-shape (Fig. 9, not shown) form a tapping connector. W-shaped double terminals (Fig. 10) for joining wires end to end are mounted by means of slots 61 in a plastics housing 56 with a snap-on lid 62. Terminals 72 (Fig. 14) for a tape cable 18 are mounted in a block 88 with a cover 96. Integral pins 71 enter cavities 92 in a block 90 having socket contacts soldered to p.c. conductors 98.

Abstract: 958,756. Sensing records; digital data storage; automatic character reading. DE STAAT DER NEDERLANDEN TEN DEZE VERTEGENWOORDIGD DOOR DE DIRECTEUR-GENERAAL DER POSTERIJEN TELEGRAFIE EN TELEFONIE. Sept. 18, 1962 [Oct. 2, 1961], No. 35464/62. Headings G4C, G4M and G4R. In a reader for characters having code elements arranged in three rows and three columns, 1, 11, 111 Fig. 3 each code element is scanned by three scanners simultaneously, as shown in Fig. 1, and the result given by the majority is taken and where there is more than one code element in a column the majority results are taken only if for each element they come from corresponding adjacent scanners. A vertical displacement of the record may cause the lowest of each group of three (1-3,4-6, 7-9 Fig. 2) to sense no code element. The upper two will therefore give majority signals both for the top element a and the bottom element c. Fig. 5 shows a circuit which ensures that both majority signals are from the top pair or the bottom pair. The nine sensing members 1-9 are gated at appropriate times with "black" or "white" triggers A1, A2, A<SP>1</SP>1, A'2 &c. for each code element. For each group of three scanners e.g. 1, 2, 3 there are two black and two white triggers A1, A2 and A<SP>1</SP>1, A<SP>1</SP>2 respectively. Triggers A1, A<SP>1</SP>1 are connected to the upper pair of the group and A2, A'2 to the lower pair. Character elements sensed by the upper pair of each group set the triggers A1, A<SP>1</SP>1, B1, B<SP>1</SP>1 &c. The outputs of all these triggers are gated together in suitable combinations to identify the character. Triggers A2, A<SP>1</SP>2, B2, B'2, responding to detection of a character element by the lower pair of each group, are applied to a similar gate. One or other of these gates will respond depending on the registration of the character and on output trigger is set through an 0r gate to identify the character. Specifications 820,283 and 916,157 are referred to.

Title: Apparatus for the electric transmission of alphabetical, numerical and like characters
IPC: H04L21/02
Filed: 1937-12-22
Abstract: 505,051. Type - printing telegraphy ; facsimile printing telegraphs. LORENZ AKT.-GES., C. Dec. 22, 1937, No. 35504. Convention date, Dec. 22, 1936. [Class 40 (iii)] A telegraph transmitter having separate code discs for each character which are selectively clutched to a driven shaft is characterized in that on depression of a key a disc member, appertaining to the key depressed, is coupled to a driving shaft, the other keys being thereupon locked during the first portion of the rotation of the driving shaft. Each code disc 2, Fig. 1, loosely mounted on a shaft 1, carries on its hub an oval ring 3 having an inwardly projecting lug 10 such that when it is. forced inwards by a spring 4 the lug 10 engages a slot in the rotating shaft 1. The ring is normally held out of engagement with the shaft by a projection 17 bearing against a cranked lever 5 held by a projecting lug 8 on a pivoted lever 30. Depression of a key bar 6 tilts this lever 30 through a link 7 so allowing the lever 5 to move away from the shaft 1, with the consequent locking of the appropriate disc. In its movement the lever 5 strikes a common bar 34 which, through mechanism 12, 35 tilts a lever 38 so releasing a pawl 39 from a ratchet on the shaft 1 allowing rotation. When one revolution of the shaft is completed the pawl is restored by an arm 44 and the key having already been released, the levers 7, 30, and 5 return to their normal position such that the lever 5 forces the ring 3 out of engagement with the shaft. A pawl mechanism, Fig. 2 (not shown), similar to that described operates on a second shaft geared to the previously mentioned driving shaft to lock all keys by means of a common bail until the driving shaft has turned through a small angle. If a second key is depressed while a previous signal is being transmitted it serves to release the appropriate ring so that when the first revolution is completed it moves into the slot in the driving shaft for rotation.

Title: Explosive composition
IPC: B29C48/03
Filed: 1966-08-12
Abstract: A detonating fuse composition comprises an intimate mixture of, by weight, 40-80% of a particulate cap-sensitive high explosive, 15-50% of a polymeric metallocarboxylate elastomer, and 1-20% of a plasticizer.  Also present may be up to 25% of a polyurethane elastomer formed, for example, from a polyether and a diisocyanate. The explosive component may be one or more of PETN, RDX, tetryl, TNT, HMX, mannitol hexanitrate, tetranitrodibenzo-1,3a, 4,6a-tetraazopentalene, diazodinitrophenol, hexamethylene triperoxydiamine, picrysulphone, potassium dinitroacetonitrile, and lead azide. The metallocarboxylate elastomer is formed in situ by reaction of a carboxylic copolymer with a polyvalent metal ion; a preferred copolymer is derived from butadiene-1,3, acrylonitrile, and methacrylic acid, but many other copolymers are referred to.  The metal ion source may be provided by a metal oxide, hydroxide, or salt, or by finely-divided metal.  A number of suitable plasticizers are listed, for example triethylene glycol di-2-ethyl hexoate.  The explosive composition may also contain stabilizers, colouring agents, odorants, antioxidants, and retardants.  An aqueous dispersion of the carboxylate copolymer may be mixed with the other constituents and the mixture dried, shaped by rolling or extrusion, and finally cured. The formed articles may be reinforced with threads or yarns of nylon or other material. An apparatus is shown for making a detonating fuse of improved flexibility by extruding the composition around a central reinforcing thread. In examples of the composition, the explosives are PETN, tetryl, and RDX, and other components not specified above are di-beta-naphthyl-p-phenylene diamine, stearic acid, zinc oxide, lead oxide, dibutyl phthalate, and 4,41-methylene-bis(2-chloroaniline).
