Title: Solderless electric connectors
IPC: H01R12/67
Filed: 1976-01-19
Abstract: 1480582 Two part couplings QUEST ELECTRONIC CONNECTEURS 19 Jan 1976 [31 Jan 1975] 01905/76 Heading H2E A "flat cable" connector has two parts 4 and 5 which include means (e.g. projections 46, 47 and wall 11) for preventing incorrect assembly, locking means (resilient arms 43, 44 and abutments 10) for locking the two parts together and a plate 17 for retaining the terminals 20 of the second part 5 when the elements of that part are disassembled. The second part comprises a body 15 containing insulation piercing forked terminals 20 in through passages 19 (only one shown) a plate 17 with holes to accept the terminals and retain them in the body, a cap 16 with holes 30 to receive the terminal ends, conductors 1 being forced by the cap between opposing tines of the terminals which pierce the insulation and contact the conductors thereof, and a stirrup piece 18 which engages resiliently over portions 41, 42 of the body to retain the cap and body together and damp the cable between itself and the cap. The thus formed second part may then be engaged with the first part 4, which is mounted on, e.g. a circuit board, by sliding resilient arms 43, 44 between guides 8, 9 until the arms snap into place.

Title: Improvements in or relating to signalling systems for giving signal indications on trains controlled magnetically from the track, and vice versa
IPC: B61L3/12
Filed: 1937-01-22
Abstract: 488,724. Apparatus for signalling between train and track. VEREINIGTE EISENBAHN-SIGNAL-WERKE GES. Jan. 22, 1937, No. 2002. Convention date, Feb. 4, 1936. [Class 105] . Signalling between train and track is effected by magnetic transmitting and receiving members each having at least three poles with a permanent magnet provided in the core between two poles of the transmitting member. The receiver comprises magnetic relays 28 . . 30 which are shown as being of cartridge form for insertion in borings through the pole pieces ; the relays are polarized and therefore are operated only by a flux as indicated by their arrow. At a danger signal only the permanent magnet 1 is effective and therefore the receiver relays 29, 30 are operated so setting up a circuit to give such danger signal on the train. At a caution signal the electromagnet 10 is energized in the direction to set up a flux in line with that of the permanent magnet 1 which flux therefore traverses only the outer pole pieces 12, 14; this flux operates the receiver relay 30 but not the receiver relay 28 on account of its particlar polarization. The relay 30 operated alone then sets up a circuit to give the caution signal on the train. At a clear signal. the electromagnet 10 is energized in the direction to set up a flux opposing that of the permanent magnet 1 and thus the two fluxes rise through the pole piece 13 and respectively return downwards through the pole pieces 12, 14 and accordingly all the receiver relays 28 .. 30 are operated thereby setting up a circuit to give the clear signal on the train. The signal circuits, Figs. 7-14 (not shown), in certain cases include slow relays and require that one receiver relay, namely relay 30, be slow acting.

Title: Method and apparatus for drying materials
IPC: F26B23/00
Filed: 1974-01-17
Abstract: 1448762 Drying materials SINTAB SWEDINVENTOR AB 17 Jan 1974 [18 Jan 1973] 02144/74 Heading F4G The invention relates to a method of and apparatus for drying material in liquid, granular, powder or plastic form. The method comprises the steps of feeding a plurality of heated heating elements 55 of high specific heat, e.g. 0À9 cals./grm.‹ C. and the material 25 to be dried together into a tank 1 set under subatmospheric pressure, e.g. 10 mm. of mercury, discharging the mixture of material and elements when the material is dry and separating the material from the elements. As shown the elements 55 are fed from a hot water heat exchanger 5 to a compartment of a primary tank 2 while the material 25 is fed to another compartment thereof through respective valves 58, 26. Before the mixture is fed through a valve 16 to the tank 1 the primary tank 2 is evacuated. In the tank 1 water vapour driven from the material is condensed by sprays 65 of cold water in a compartment at the upper end of the tank. The dried material and elements pass into a secondary tank 3 in which they are separated by a vibrating screen 74.

Title: Improvements in Devices for Coupling Circuits in Wireless Telegraphy and Telephony, so as to Produce Oscillations having a Strictly Single Frequency.
Inventor: BELLINI ETTORE
IPC: H03B11/02
Filed: 1916-02-21
Abstract: 126,978. Bellini, E. Feb. 21., 1916. Wireless signalling; electric oscillations, producing.-Two oscillatory circuits are coupled so as to produce oscillations having a single frequency by a combined magnetic and electric coupling each having the same coupling-coefficient, the electromotive force induced electrically being in the opposite direction to that induced magnetically, and the circuits being tuned to resonance after the electric coupling only has been effected. The general case shown in Fig. 1 comprises a generating-circuit with resistance 9, inductance 1, and capacities 3, 4, and the secondary circuit includes resistance 10, inductance 2, and capacities 5, 6. The coupling-condensers 7, 8 are connected across the capacities 4, 6. In coupling up the circuits, the electric coupling 7, 8 is first established, with no magnetic coupling. The inductance of the secondary circuit is then varied until maximum current is obtained. The magnetic coupling is then established and its direction and amount varied until a wave-meter shows that a single frequency exists. One of the coupling-condensers 7, 8 may be replaced by a conductive coupling, and an inductance 13 may be included in a common branch of the two circuits, as shown in Fig. 3, in which the secondary circuit includes an aerial 11 and earth connexion 12. If both coupling-condensers 7, 8 are short-circuited and the magnetic coupling takes the form of an autotransformer 13, the arrangement shown in Fig. 4 is produced, and the condition for equality of the coupling coefficient necessitates that the natural frequencies of the three branches 1, 3, 9; 13, 14, 15; 2, 10, 11, 12 should be the same. The capacity of the condenser 3 may be made infinite, i.e. the condenser may be short-circuited, and the abovementioned condition then requires that the inductance 1 should be reduced to zero. For receiving- circuits, a detector and telephone may be shunted acrose a condenser in the secondary circuit. The secondary circuit of Fig. 1 may be a closed-circuit directive aerial, the inductances 1, 2 being duplicated at the opposite side of the coupling-condensers.

Abstract: 561,894. Arming devices for bombs, projectiles or the like. HEBARD, H. C., and IMBER RESEARCH, Ltd. March 3, 1941, Nos. 2850 and 7327. [Class 9 (i)]. A safety arming device for a bomb, projectile, or the like, comprises a striker held against movement by balls in a cylindrical ex. tension of the striker, and a wedge adapted to be released by a windvane to release the balls so that i he striker is moved by a spring. The striker a is prevented from movement by a hand-released pin c and also by balls h disposed in recesses g in a cylinder f attached to the striker-rod e. Coact. ing with these balls, to cause them to engage a shoulder i on the casing, is a wedge j normally retained in locking position by a screw k adapted to be moved axially by a wind-vane m, which can screw along the screw k until the nut n<1> on the vane abuts against the head of the screw, whereupon the vane and screw rotate together to release the wedge. If the angle of the wedge is less than the critical angle, the wedge is not forced back to release the balls by the action of the plunger spring c until impact occurs, but if the angle is greater than the critical angle then the force of the plunger spring forces the wedge upwardly by means of the balls as soon as the wedge is released and firing occurs at this time. The detonator d may fire the charge directly or through a time fuze. A protection cap p is held over the wind vane normally by spring arms r, but is released by hand or automatically at the moment of discharge.
