Title: Improvements in electrical systems involving three electrode thermionic tube elements
IPC: H03F1/40
Filed: 1920-07-12
Abstract: 148,995. Latour, M. Dec. 16, 1918, [Convention date]. Void [Published under Sect. 91 of the Act]. Thermionic relays and repeaters.-Relates to a thermionic tube system intended to create the effect of a negative resistance. The plate circuit of the tube 1 comprises two batteries 3, 5, and .a resistance 12, and the voltage of the battery 5 is arranged to compensate normally for the drop of potential between the terminals 10, 11 of the resistance 12 so that normally the voltage between the terminals is zero. The two batteries 4, 6 and the resistance 15 are similarly connected in the plate circuit of the tube 2 so that the voltage between terminals 13, 14 of the resistance 15 is zero. If a current (value i) flows through imped- .ance 9 (value z) it produces a voltage z i between the grid and filament of tube 1, and it is stated that this voltage, successively amplified by the two tubes 1, 2, results in producing the equivalent of a negative resistance between the terminals 13, 14. This negative resistance may be obtained of any desired value by making impedance 9 of a suitable value and any desired number of pairs of tubes may be used. The device may be inserted in a telephone line to balance the impedance of the line.

Title: Improvements in or relating to Logic Circuits
IPC: H03K19/096
Filed: 1968-05-06
Abstract: 1,190,121. Transistor logic circuits. NATIONAL CASH REGISTER CO. 6 May, 1968 [9 June, 1967], No. 21290/68. Heading H3T. [Also in Division G4] In a logic circuit having three stages each consisting of three M.O.S. field effect transistors 76, 84, 90; 96, 102, 108; 114, 122, 128, connected as shown three sets of clock pulses # 1 , # 2  and # 3  are applied in first, second and third time intervals t 1 , t 2 , t 3  (Fig. 3) so that an output is obtained at B 3  in response to a logical input " 1 " or " 0 " at X under the control of the clock pulses # 1 , # 2  and # 3 . The operation of the circuit can be seen from Fig. 3. When the clock pulse # 1  is applied transistor 76 turns ON and allows the gate-substrate and stray capacitance 70 to charge at B 1  to - V. Similarly when # 2  occurs transistor 96 turns ON to charge similar capacitance 72; also # 2  turns ON transistor 84 and depending on the logical input X, " 1 " or " 0 " represented by - V or 0 volts, transistor 90 turns ON or OFF respectively so as to discharge or unaffect the capacitor 70. The clock pulses # 1  and # 3  similarly cause the transistors 122, 102 to turn ON and depending on the charge on the capacitors 72, 70 either cause the transistors 128, 108 to turn ON or OFF so as to discharge or unaffect the capacitors 72, 70. The output voltages B 1 , B 2 , B 3  are dependent on the signals at X, B 1  and B 2  and the clock pulses respectively. The output B3 can be connected to the input of similar stages and the input X may be taken from the output B 3  of a preceding stage. The transistors 90, 108, 128 in any one or more of the stages may be replaced by a series and parallel complex logic transistor network (66, Fig. 4, not shown), requiring a plurality of inputs X m,1 -X m,n ; X 1,1 -X 1n . The substrates of all the transistors are connected to a common reference potential. The Specification states that the field effect transistors can be employed in integrated circuitry. Reference has been directed by the Comptroller to Specifications 1,130,055 and 1,122,411.

Title: Improvements in and relating to tobacco feeding mechanism for cigarette making machines
IPC: A24C5/39
Filed: 1935-07-27
Abstract: 446,719. Cigarette-making machines. AMERICAN MACHINE & FOUNDRY CO., 511, 5th Avenue, New York, U.S.A. July 27, 1935, No. 21411. Convention date, April 13. [Class 130] Long and short tobacco shreds are fed by separate mechanisms to a common means arranged to receive or remove tobaccofrom both, to comingle the long and short shreds and to deliver a single stream or shower of the co-mingled shreds. A feed roll 27 showers short shreds S from a hopper 19 between the blades 16 of a rapidly rotating picker and winnower 16, 17 which has removed from a carded roller 6 a layer of long shreds T supplied from a hopper 5. A comb 8 presses the long shreds on to the roller 6 and a pivoted plate 31 lies on the card of that roller to grip any abnormally large lumps of tobacco while pins 17 on the blades 16 tear them up. The winnower co-operates with a curved plate 18 to shower the tobacco on to a conveyer 10, heavier unwanted particles being caught in a removable tray 18a. The conveyer 10 leads to feed rollers 11 .. 13 which shower the tobacco on to the cigarette paper P. The sides of the hopper 19 are adjustable towards or away from each other to determine the width of the shower of the short shreds and deliver a narrower, central stream of tobacco on to the longer shreds to permit these entirely to surround the short shreds in the cigarette. Cam operated agitating rods 32 dip into the short shreds S.

Title: Improvements relating to devices for delivering measured quantities of material
Inventor: SMITH ARTHUR HENRY
IPC: G01G13/00
Filed: 1960-06-18
Abstract: 969,612. Weighing apparatus. BENFORD Ltd. Sept. 4, 1961 [June 18, 1960], No. 21486/60. Heading G1W. A batch weigher comprising a weighing receptacle carried by a support structure 15 permitting movement between loading and discharge positions and including an indicator 58 to show the weight of material delivered to the weighing receptacle has a hydraulic capsule 41 to which a pre-load can be applied which is reduced as material is delivered into the weighing receptacle. The structure 15 is a triangular frame which is swung on a vertical pivot 32 between a position where the weighing receptacle is under a material storage container e.g. a cement silo, and a position where the weighing receptacle is discharged by opening a pivoted flap in its base against a spring or counterweight. By the turning of a handle 48 an internally threaded spindle 47 is caused to co-operate with a screw threaded shank 50a and apply a load to the hydraulic capsule 41 by means of a spring 52. A weighbeam 43 is fulcrumed on a horizontal spindle 37 at the end of the structure 15 remote from the pivot 32 and extending outwards from it are laterally spaced limbs 56 from which the weighing receptacle is suspended on trunnions. One arm 54 of the weighbeam reacts on the capsule 41 and has a socket 55 in which the bottom end of the spring 52 rests. The handle 48 is operated to set a gauge reading by pre-loading the hydraulic capsule; then, as cement is delivered into the weighing receptacle, the weighing beam arm 54 exerts an up-thrust against the lower end of the spring 52 until the weight balances the pit load, this condition being indicated by zero reading on the gauge. Micro switches may be arranged to operate when the pointer of the gauge reaches its zero position and initiate means to shut the outlet of the hopper, lock the support 15 against movement unless the gauge is at zero and/or lock the flap at the base of the weighing receptacle. Pneumatic or hydraulic control may be substituted for electrical. Specification 605,558 is referred to.

Title: Improvements in dimension measuring devices
IPC: G01B11/08
Filed: 1963-05-30
Abstract: 1,040,068. Machine tool details. MAVILOR MANUFACTURE DE VILEBREQUINS DE LORETTE. May 30, 1963 [June 6, 1962], No. 21620/63. Heading B3B. [Also in Division G1] Dimension measuring apparatus comprises means for forming an image of a slit at a first surface element of a test object, a pair of optical reflecting means, at least one of which is movable, forming from the portion of said first image not cut off by the object a second image at a second surface element, and means for displacing said optical reflecting means until the second image is just being formed. Light from a source 1, Fig. 1, forms an image I of a slit 2 at a point S 1  on a cylindrical test object P. The light not cut off by the object P is made parallel by a lens 6, reflected by prisms 4, 5 and focused by a lens 6a to form an image I 1  at the point S 2 . When the axis T 1 , T 2  are further apart than the diameter of object P, the photo-cell 8 receives light and produces a signal which actuates a controller 27 to feed a high-speed motor 21 which moves the light source 1, photo-cell 8 and prisms 4, 5 simultaneously by means of a Selsyn coupling 19, 14 to reduce the photo-cell output. When the output falls to a preset level, a discriminator 25 switches off motor 21, engages a clutch 23 and energizes a slow-speed motor 22. This anticipation of the measuring position may be effected by a prism 31 which deflects the image S 2  towards a photo-cell 8a. The output of which on reaching zero changes over from motor 21 to motor 22 and removes prism 31 from the light path. The position of the prisms 4 and 5 is measured using the system described in Specification 1,040,070. To measure different diameters, the object P is rotated and the light source flashed in synchronism, the phase of the flashing being made adjustable. The system is adaptable to measure axial dimensions such as the distance between shoulders, Figs. 2, 3 and 4 (not shown), and eccentricities, Fig. 5 (not shown). In certain cases only the light source and the prism 4 need be movable. The light source 59, Fig. 6, detector system 60 and prism arrangements A, B may be mounted on a bracket 55a which is supported on a carriage 53 allowing movement in two dimensions for setting up. Reference has been directed by the Comptroller to Specification 826,846.

Title: Hardening polymerisable compositions
IPC: C08G75/045
Filed: 1966-05-16
Abstract: 1,145,159. Polymerizable compositions hardenable in air. SCM CORP. 16 May, 1966 [14 May, 1965], No. 21735/66. Headings C3C and C3P. A composition which can be polymerized in air comprises one or more liquid vinyl or vinylidene monomers containing at least one hetero atom and/or an aromatic ring and 0-40% by weight of a vinyl or vinylidene polymer, which may or may not correspond with the monomer(s), together with a peroxide-free redox catalyst system whose oxidizing component is a lipo. philic organic vanadium compound, in which the vanadium has an oxidation state greater than II, and whose reducing component is a mercaptan. Suitable monomers include acrylic, methacrylic and vinyl esters, and styrene and its derivatives such as α-methyl-styrene and pvinyltoluene; these may be used, if desired, in admixture with 1-10% by weight of a crosslinking monomer such as ethylene glycol dimethacrylate, diallyl phthalate or diethylene glycol bis-allyl carbonate. When the monomer is used together with preformed polymer, the combination may be obtained (as illustrated in the examples) by prepolymerizing the monomer. The vanadium compound may be a complex of tri- or tetra-valent vanadium with a tautomeric compound such as acetyl acetone, benzoyl acetone, an acetoacetic ester or a benzoyl acetic ester; also suitable are vanadium derivatives of 5-chloro-8-hydroxyquinoline, 5,7-dibromo-8-hydroxyquinoline, di- (2- ethylhexyl ) - phosphate and p-toluenesulphonic acid. Suitable mercaptan reducing components are aliphatic straight-chain primary mercaptans having 4-16 carbon atoms. The catalyst components may be added simultaneously to the monomer or, alternatively, the oxidizing component may be added after the reducing component; the mercaptans serve to stabilize the monomer for storage purposes. The composition may include an additional stabilizer such as 2-mercaptobenzthiazole or 2-mercaptothiazoline. The composition may be polymerized at a relatively low temperature, e.g. room temperature or 30 C. Suitable applications of the compositions include glass fibre laminating, adhesives for acrylic glasses, foams, casting of acrylic resins, and encapsulation of electronic components. The composition can be foamed by including a foaming agent, e.g. azobisisobutyronitrile, therein and heating at elevated temperature after completion of polymerization. This is illustrated in Example 1.
