Title: Improvements in or relating to transistor bistable circuits
IPC: H03K3/012
Filed: 1962-12-11
Abstract: 1,006,719. Electronic counter. ROCHAR ELECTRONIQUE. Dec. 11, 1962 [Dec. 26, 1961], No. 46712/62. Heading G4A. [Also in Division H3] A transistor bi-stable circuit of the type comprising at least one pair of main cross-coupled trigger transistors and a pair of auxiliary gating transistors which steer trigger pulses to the main transistors to cause switching includes a further pair of auxiliary transistors, one of which feeds the gating pair with triggering signals and the other feeds the trigger pair with triggering current signals. As shown in the figure if transistor 1 of the main trigger pair is conducting the other transistor 2 of the pair is cut off, the current for transistor 1 flowing through conducting transistor 6 from constant current source 26, 27. In the absence of any input signal at terminal 25 transistor 5 will be biased off by the current flowing through resistor 26 and hence gating transistors 3, 4 will also be cut off. If a negative input pulse is applied to terminal 25 of appropriate amplitude transistor 5 will delivery a current pulse resulting in transistor 6 and hence transistor 1 being cut off. Since transistor 1 was conducting and transistor 2 blocked at the instant of applying the negative input pulse, the base of transistor 3 was more negative than that of transistor 4 and so the current pulse from transistor 5 passes through transistor 3, diode 10 and resistor 16 causing the base of transistor 1 to become less negative than that of transistor 2. At the end of the input pulse at 25 the current output from source 27 is transferred from transistor 5 to transistor 6 and since the base of transistor 2 is now more negative than that of transistor 1, transistor 2 is switched on and transistor I is switched off. The waveforms transmitted by the gating transistors 3, 4 are delayed so as to avoid their interference with a previously initiated and uncompleted changeover of state by the " Boucherot " circuits 14, 15, 16, 17 and 18, 19, 20, 21, the values of the components being such that the circuits when viewed from the points M and P respectively have a pure resistance equal to resistances 14 or 18. The output of the circuit is taken via coils 21, 22 to the base of the input transistor of the following bi-stable stage of a counter arrangement.

Abstract: 1,271,220. Earth drills. INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS. 1 Oct., 1970 [6 Oct., 1969], No. 46779/70. Heading E1F. Rotary drill is associated with a penetro meter for testing the soil, consisting of a probe 4 which may be pushed downwards through a central opening of the drill, and means (not described) for measuring the force required to insert the probe to a predetermined depth. The drill has a fixed bit 2 which leaves a central core 16 for the penetrometer, and a cutter 8 is provided to remove the core when the probe 4 is retracted. The cutter 8 (Fig. 1) is mounted on a pivot 7, and is swung inwards to cut the core, by, centrifugal force on a weight 6; the cutter is offset so that friction on the cutting edge urges the cutter inwards. When the drill is stopped, the cutter is swung outwards to clear the probe by a spring 11 connected to a balancing weight 9.  The drill may also have nozzles 30 (Fig. 4) for jet drilling with the probe continuously extended. In this embodiment the cutter 8 is fixed to a vertical pivot 7 and a spring loaded piston 20 acts as a valve so that with a high drilling mud flow rate, it is forced downwards to close passages 23, so that the drilling and mud flows through the jet drilling nozzles 30. If the drill is rotating however, a projection 35 (Fig. 5, not shown) on the weight, projects an opening in the wall 18 to obstruct the piston. The drilling mud then flows also through passages 33, 31, a screen 32, and passages 38. Operation of the drill may be controlled by pressure pulses transmitted up the drill string through the drilling mud.

Abstract: Apparatus for playing a game simulating golf comprises a playing box providing a transparent playing surface, means for positioning a sheet of material having a plurality of symbols thereon representative of a golf hole under the playing surface, means for moving the sheet with respect to the playing surface, said playing surface having at one end, thereof a plurality of concentric circles. In the particular apparatus described, the sheet of material is in the form of a roll which is on a windable spool at one end of the box and is wound onto a spool at the further end of the box.  The green of the hole is positioned under the concentric circles.  In play, a player selects a fan-shaped card representing a particular golf club, places this on the transparent sheet and then from a number obtained by chance (e.g. a rotating pointer on a numbered disc) and tables indicating distance and direction, marks the surface of the playing sheet through an appropriate hole on the "club".  Successive "strokes" are made with selected "clubs" until the green is reached when a table is used together with the chance means to establish the number of putts required.  The avoiding of hazards on the course using markings on the "clubs" and further tables is also described.

Abstract: Removing catalyst residues from polyolefines obtained by polymerizing olefins in an inert diluent in the presence of a Ziegler-Natta type catalyst, wherein the slurry of the polymer obtained from the polymerization is treated with an alkanol to solubilize the residues, under an atmosphere substantially free of oxygen and water, following which a phenol, which is defined later, is added to the alkanoltreated slurry, the polymer then separated from the slurry, and subsequently washed with an inert liquid hydrocarbon.  The phenol has the formula <FORM:1058354/C3/1> where R1, R2, R3, R4 and R5 are selected from alkyl, aryl, alkaryl, aralkyl, alkoxy, aryloxy, alkylaryloxy, carboalkoxy, carboaryloxy, or carboalkylaryloxy radicals, and hydrogen atoms, and the substituents are selected so that the reactivity of the phenolic hydroxyl group is substantially unhindered.  The slurry may also be treated with an alkylene oxide, e.g. propylene oxide.  The exemplified polyolefin is polypropylene, and the alkanol n-butanol and isopropanol. The Specification contains a long list of phenols of which are exemplified nonylphenol, octylphenyl salicylate, phenyl salicylate, 2,6 - di - t - butyl - p - cresol, a nonylphenol - acetone condensate, ortho - tert.-butyl-phenol, salicylic acid and phenol.  A small amount of an antioxidant may be added to the slurry prior to filtration.  The preferred diluents are aliphatic hydrocarbons boiling in the range of 70-250 DEG  C.
