Title: Gas chromatography method and apparatus
IPC: G01N30/80
Filed: 1972-09-21
Abstract: 1378807 Gas chromatography TEXACO DEVELOPMENT CORP 21 Sept 1972 43736/ 72 Heading B1H A method of gas chromatography in which a sample is separated into components that are spaced apart chronologically at the outlet from a separation column, the effluent from the column being divided into first and second portions, the first portion of the effluent is trapped at said outlet with a physical separation corresponding to the spacing of peaks on a graphic record made simultaneously with the trapping of a characteristic of the second portion of said effluent comprises directing the first portion of said effluent into impingement against a moving surface for retaining some of said components thereon and moving said surface at the same speed as said graphic record whereby said retained components may be related to said record peaks. In an exemplary apparatus the effluent from the column is split into two parts; one goes to an ionisation detector the output of which gives a normal type of chromatogram, the other is trapped on a tape of paper, foil or coated fibre-glass; the tape is driven at the same speed as the material in which the normal chromatogram is produced, so that when the two are subsequently laid side by side the peaks of the chromatogram indicate the location on the tape of separated components which may be removed for analysis.

Filed: 1967-09-27
Abstract: 1,204,153. Electro-chemical machining electrode. SIEMENS A.G. Sept.27, 1967, No.44064/67. Heading C7B. An electro-chemical machining electrode has face (which in use is opposed to the workpiece) bounded by a periphery, that defines a corner. At the periphery, the electrode has strip-form edge regions, e.g. 24 in Fig. 2a, substantially perpendicular to the said face and narrowed towards the corner so that, when the electrode is in use, substantially the same anode current density can be obtained adjacent to the corner as at the remainder of the periphery. As shown, the narrowing of the strip-form edge regions is achieved by tapering the foot of an electrode assembly. Alternatively, the narrowing could be achieved if the foot were suitably coated at its edge regions with insulating lacquer, e.g. epoxy resin, or with material which is more highly cathodically polarizable than the remainder of the foot, e.g. lead applied by electro-deposition. In use, the electrolyte may be supplied through a hollow support stem and the foot. As shown, the stem and top of the foot have a coating of insulating material. Whereas Fig. 2a shows a tool for producing cavities, Figs 4a-c (not shown) illustrates a tool electrode for producing projections of triangular cross-section.

Patent GB-1481336-A (GB)
Title: Electronic timepiece
IPC: H03L1/02
Filed: 1974-10-14
Abstract: In addition to an oscillating circuit constructed as a clock pulse generator (91) and having a temperature frequency response as low as possible, the time-measuring instrument has a further oscillating circuit (92) which has a temperature frequency response deviating therefrom and preferably higher. A counter (98) counts the pulses of this further oscillating circuit and a temperature-dependent signal is formed by arranging for the counter results to be stored in a memory during a period which is essentially determined by a time counter (912) driven essentially by the clock pulse generator (91). Said signal is transmitted periodically to a frequency converter (91) whose output signal is used to correct the signal transmitted by the clock pulse generator to a reduction mechanism (911) which drives the time counter (912). At least some of the said circuit parts consist of CMOS integrated circuits. <IMAGE>

Abstract: 1429542 Propelling motor vehicles NISSAN MOTOR CO Ltd 21 Sept 1973 [22 Sept 1972 (2) 31 Oct 1972] 44474/73 Heading B7H A motor vehicle is propelled by a prime mover and/or a flywheel driven by the prime mover through a disengageable coupling, the rotational energy stored in the flywheel being controlled by means responsive to the speeds of the prime mover and flywheel, the prime mover being stopped when the vehicle is halted, the vehicle being driven by energy stored in the flywheel when restarted. A prime mover 20, Fig. 1, e.g. an internal cumbustion engine, has a crank-shaft 22 which drives an intermediate shaft 24 through a torque converter 27. The shaft 24 drives a shaft 26 through a clutch 28, the shaft 26 being connected to a propeller shaft 30. First and second pinions 32 and 34, rotatable on the shaft 24, are associated with first and second clutches 36 and 38. The pinions 32, 34 mesh a bevel gear 40 rotatable on a shaft 42 carrying a gear meshing a gear 50 on a shaft 52 of a flywheel 54. A variable speed drive comprises rotary members 62 and 64 and a roller 66, the first member 62 being secured to the bevel gear 40, while the second member 64 is secured to the shaft 42. The speed ratio is varied by inclining the roller 66 as in a Hayes transmission. The first and second clutches 36 and 38 and the inclination of the rollers 66 are controlled from an electric control unit 76 by means of solenoids 78, 80 and 82. With clutch 36 coupled and clutch 38 uncoupled drive is established from shaft 24 to the flywheel 54 at a speed related to the position of roller 66, the drive from the gear 34 to the shaft being interrupted, so that the power output of the engine 20 is absorbed by the flywheel. With clutch 38 engaged the engine 20 and flywheel 54 drive the intermediate shaft 24, or should the engine be at rest, with clutch 36 uncoupled, only the flywheel drives the shaft 24. The control unit 76 may also take account of engine r.p.m., flywheel r.p.m., vehicle speed, brake pedal position, accelerator and clutch pedal depression. In a modification, a fourth clutch (156), Fig. 4 (not shown), is interposed between intermediate shaft (24) and the crank-shaft 22, the clutch (156) being controlled by means responsive to the position of a brake pedal, the energy stored in the flywheel, and the speed of the motor vehicle, so as to permit braking of the vehicle by the flywheel. In another embodiment, the flywheel 54, Fig. 6, is carried on a shaft directly connected to shaft 42, only one clutch 158 being interposed between the shaft 24 and flywheel 54. In a further embodiment, Fig. 8, a flywheel 194 is axially slidable on an intermediate shaft 160 to engage a clutch face 192 on a disc 190 by means of a control lever 220 actuated by a solenoid 210 against the bias of a spring 206. The solenoid 210 together with other solenoids 178 and 188 are controlled by a control unit 288 responsive to engine r.p.m., r.p.m. of input shaft 164, flywheel r.p.m. and the position of clutch and brake pedals with the aid of vacuum from a source 220.

Abstract: 959,151. Digital data storage. K. A. SUMIDA, and R. C. SADLER. Nov. 26,1962, No. 44655/62. Heading G4C. Magnetic dots are manually recorded on a tape by pressing the tape and a magnetic carbon against "printing" slides. Slides 96 (Fig. 13) are differentially moved by moving fingerpieces 48 (Figs. 1 and 13) until the required numbers are displayed at the bottom of the columns. Each slide is connected to its associated fingerpiece by an arm 104 and a lug and slot connection 105, 106. A pawl 138 holds a slide set against the action of a spring 132. Other printing slides are set by the insertion of two cards 42, 44 which have sets of upstanding lugs which engage the ratchets and move the slides the required distance. The cards are so shaped that printing is prevented unless they have been properly inserted. There is a clear button 56 which rocks an arm which releases the pawls 138 in case of error. The printing operation is caused by sliding a knob 54 to the end of a slot 55 and back again. Full-stroke mechanism is provided. The knob 54 is supported on a carriage to which are attached cables which reciprocate an eccentrically mounted wheel across the printing area. On the upstroke of knob 54 the wheel 66 (Fig. 24) is moved to the left and is rotated against the action of a spring by the engagement of arm 305 with catch 300. Printing takes place during this movement. On the return stroke of knob 54, catch 300 is released and arm 305 engages a lever 116 which is rocked to grip the record and carbon tapes against a wheel 325 and advance them.

Abstract: 1479177 Keyboard device for an electronic musical instrument ROLAND CORP 16 Oct 1974 [26 Oct 1973 5 Aug 1974] 44838/74 Heading G5J A keyboard device for an electronic piano is designed to respond to variations in touch on the key. A key frame 1, pivoted at 6, carries a hammer 11 which on depression of the key, pivots about a point 10 and hook 13 and is thrown in the direction "b" to strike sensor 27. Mechanical damping pad 28 is released on depression of the key so that the sensor, which may be capacitive, piezo-electric or mechanical, modulates the signal generated for the particular note struck, according to the strength of the blow delivered by hammer 11 (Fig. 8, not shown). In a second embodiment (Fig. 9, not shown). The sensor comprises a lever which is shifted from one contact to another so that the time taken for the switch to occur, as measured by the discharge of a capacitor, is a function of the force with which the key was struck. Whilst the key is depressed, damper switch 25 remains open (due to pressure from tip 26 of pack 12) so discharging a capacitor in an attenuation circuit (Figs. 7, 14, not shown), which has the effect of attenuating the volume of the note played. "Double beats" are prevented by lever 21 which prevents hammer 11 from returning to plate 24 before the key is released. Lateral movements of the key are prevented by baseplate 8.
