Title: Improvements in or relating to cutlery grinding machines
IPC: B24B19/00
Filed: 1921-03-10
Abstract: 181,459. Anderson, T., and Pearson, J. W. March 10, 1921. Disc apparatus; cutting-edges, shaping and treating.-A cutlery-grinding machine comprising a grinder 2 and a blade-holder 3, which is mounted on a table 4 pivoted to a reciprocating carriage 6, is arranged so that the table is moved towards the grinder at the end of its idle stroke and the beginning of its grinding stroke by an angularly moving subsidiary cam 16 so that the path of the blade-holder conforms to the shape of the bolster of the blade. A main cam is formed of two drums 27, 30 connected respectively by radial webs or spokes to hubs 24, 28 keyed to a shaft 25; or the hub 28 may be mounted on the hub 24. The shaped edges of the drums 27, 30 form between them a cam-groove 8, any wear of which can be taken up by moving one drum relatively to the other. The main cam may be driven by a pinion 32 gearing with an internally-toothed ring 33 secured to the drum 30. A member 10 of a pair of members 10, 11 secured to a rocking- shaft 9 engages the cam 8, the member 11 being adjustably linked to the table 4, which is thereby reciprocated. The table 4 is moved away from the grinder about its pivot 5 by a spring 13, and towards the grinder by an arm 15, which may carry a roller, by the cam 16 acting on an adjustable sliding bar 16<B>. The cam 16 is mounted in bearings adjustable in a slot 16<A>, and is operated by a spring-controlled bar 19 from a facecam 21 detachably secured to the drum 27. An adjustable face 22 on the cam 16 may be used in addition to or as a substitute for the adjustable bar 16<B>. At the end of the grinding stroke, the arm 15 is freed by contact with an adjustable abutment 23. The grinder 2 is moved axially by a screw rotated by gears 34, 35 from a hand-wheel 36. A spring-controlled belt-shifter 38 is moved by a pedal 39 and is held by a pawl 41, which is released at the end of a cycle of operations by a detent 43 carried by the drum 30. A brake-shoe 44 is carried by the belt-shifter. The bladeholder 3 may be mounted on pivots 45 and oscillated by an arm 47 engaging an inclined plane 46 or slotted member, which may be reciprocated. " Whittening " may be rendered unnecessary by making the face of the grinder to cover the major portion of the blade and by shaping the cam 8 as a sine curve so as to vibrate the carriage 6 during its grinding stroke. According to the Provisional Specification, a hand-lever may be connected to the carriage, after disconnecting the latter from the means for automatically reciprocating it, so that the carriage may be reciprocated by hand for " whittening " the blades; also the means for moving the arm 15 may be rendered inoperative so that the blade is held against the grinder when travelling in either direction.

Title: Traffic-measuring systems
IPC: G08G1/01
Filed: 1973-02-16
Abstract: 1419563 Detecting passage of road vehicles SIEMENS AG 16 Feb 1973 [17 Feb 1972] 7655/73 Heading G4Q A traffic measuring system for use on a road, such as a motorway, having two lanes F1, F2 in which traffic moves in the same direction P comprises respective detectors 1, 2 at at least one measuring position A and a storage and averaging circuit which forms an average time interval between vehicles on each lane, and means for deriving lane comparison data. As shown, further detectors 3, 4 are provided at a second measuring position B. The output of each detector passes to a counter ZM in the form of pulses. Each time a vehicle is detected, the counter is reset to zero and its count simultaneously transferred to an averaging device MW1. Here, successive inputs are averaged and the results stored in registers R1, R2. A differencing device in device MW1 forms the difference between the old average Za of time intervals and a new interval Zn. This difference is multiplied by a factor α and then added to the contents of the registers R1, R2. Simultaneously, the difference (Zn-Za) is fed to a squaring device PB1 and thence to a second averaging device MW2 connected to registers R3, R4 in a manner similar to the device MW1 and registers R1, R2. The contents of registers R2, R4 (i.e. Zn and Sn) are supplied to a multiplier PB2 upon the production, at 60 second intervals, of sampling pulses. The circuit so far described is duplicated so that each detector 1-4 provides signals processed as above. The output a 1  from device PB2 is applied to a quotient-forming device QB together with a similar output a 2  derived from detector 2. The quotient thus formed passes to another averaging device MW3 connected to a register R5 to produce and store an average Kn(A) of the quotients derived from signals obtained at position A. A similar average Kn(B) from signals obtained at position B is fed, simultaneously with the average Kn(A) to a differencing device DB1. For normal traffic flow, X A  # X B  and Y A  # Y B  where whereas, for traffic flow with an obstacle Hi present, Z B3  > Z A1  and Z B4  < Z B2  (because of density changes due to lane swapping) and, thus, and S B3  > S A1  and S B4  < S A2  (because S B3  corresponds to free-moving, low density traffic and S B4  to restricted, high density traffic) and, thus, and hence The difference (Kn(A)-Kn(B)) is fed to an analyser AW from which a "zero" output shows no restriction to traffic flow. Moreover, for an individual measuring position, say the position A, a difference between the quotients Kn, Ka is formed by unit DB2 between sampling intervals to show the degree of change of restriction with time.  The output of the system may be used to control traffic signs.

Title: Electric incandescent lamp
Inventor: FOK MIKHAIL VLADIMIROVICH
IPC: H01K13/00
Filed: 1967-02-20
Abstract: 1,127,956. Electric incandescent lamps. FIZICHESKY INSTITUT IMENI P.N. LEBEOEVA AKADEMII NAUK SSSR. 20 Feb., 1967, No. 7944/67. Heading H1F. The incandescent element of an electric lamp is made of semiconductor material doped with donor or acceptor impurities having a concentration in the range 10<SP>17</SP> to 10<SP>20</SP> atoms per c.c. and providing energy levels not deeper than 0À5 ev from the conduction or valence bands. This concentration is sufficiently heavy to ensure that even at the working temperature of the element its conductivity is still impurity conductivity. The maximum luminous efficiency of the element occurs at higher temperatures as the width of the forbidden band increases, but the practical working temperature is determined by the thermal stability of the element, and the optimum width of the forbidden band is therefore found to be about 3 ev. Suitable semi-conductor materials having such a forbidden band width are hexagonal silicon carbide, aluminium nitride, thorium dioxide and titanium dioxide. The element is preferably self-striking (i.e. electrically conductive when cold) and if the energy levels of the impurity are about 0À3 ev deep the lamp will be self-striking above 0 C. Such levels may be produced by doping silicon carbide with aluminium. Alternatively, if the silicon carbide is doped with nitrogen or phosphorus the impurity energy levels are about 0À15 ev deep and the lamp is self-striking even at -70 C. Silicon carbide may also be doped with boron. The element is preferably mounted in a glass or quartz envelope formed with double walls, on the principle of the Dewar flask, to reduce heat losses.

Title: An improved burglar or thief alarm
Inventor: CRESSALL FREDERICK
IPC: B60R25/10
Filed: 1919-03-31
Abstract: 148,602. Cressall, F. March 31, 1919. Theft and like alarms.-In alarms of the kind in which a circuit is closed by movement of a rolling ball or a pendulum from its central position, the support for the ball or pendulum is itself mounted to allow a swinging movement independent of the movement of the pendulum &c., and of the article to which the device is attached. Means may be provided for damping such movement of the support. The device is described as particularly applicable to motor-cars, and the independent movement above referred to allows the device to adjust itself, for example, when the car is inclined by the camber of the road, without operating the pendulum or ball contact. Fig. 1 shows a contact ball a<7> normally resting in a recess or seating in a ball a<5> itself forming the upper end of a pendulum b, which tends to hang so as to keep the seating horizontal. Movement of the member b is damped by fins b<1> immersed in a viscid liquid such as glycerine. When the ball is displaced by a sudden movement, it closes circuit between the support a<4> on which it rests and an insulated contact ring b<4>. The ball is attached to a light chain b<5> secured to the inner member of a Bowden mechanism, the outer member being secured to a telescopically-mounted sleeve c<2> carrying a rubber ring c<3>. By this means the ball a' can be raised out of action or reset on its seat. Fig. 5 shows a tubular pendulum e with a heavy ring e<1> mounted to swing on a central support e<5> carried by the closure e<4> of a hollow member e<3> which is itself mounted to swing on an eye support g<2>. The member e<3> is immersed in viscid liquid in an outer casing g. Modifications are also described in which a pendulum swings about an axis only slightly inclined to the vertical and two such devices may be used normally in vertical planes at rightangles to one another. Closing of the circuit by the ball or pendulum device may sound the alarm directly, or may operate a relay which closes the alarm circuit so that the alarm continues to sound until stopped by the opening of a preferably key-operated switch. A switch may be arranged so that either direct or relay operation may be used at will, or the device put out of use. The alarm, which may be an electric horn, is preferably covered by a grating provided with spikes or otherwise given an irregular surface to make it difficult to apply a cover with a view to stopping egress of sound. The batteries, horn, relay, and contact closing device may be disposed in a locked casing.

Title: Crystalline formation
IPC: G02B5/30
Filed: 1940-05-06
Abstract: 545,185. Crystallizing. MARKS. A. May 6, 1940, No. 8123. [Class 32] [Also in Group XX] A crystalline layer deposited on a glass plate suitable for use as a polarizing agent is obtained by first forming on the plate a base unitary crystalline field having the properties of a single crystal but having " meshed " or open spaces and then filling in the open spaces by further crystal growth by momentarily flowing over the base field a super-saturated solution of the material used to form the base field or a material isomorphous therewith. The base field is preferably formed by immersing the plate support in a solution of the material, e.g. iodocinchonidine sulphate and like iodoalkaloid compounds. and gradually lowering the level of the liquid relative to the support by allowing the solution to flow out of the container at a controlled rate. The crystalline coating is applied to a stack of glass plates 51 by immersing the plates in the saturated solution contained in a suspended glass tank 50 and then lowering the tank to withdraw the liquid from the surface of the plates, leaving a crystalline film thereon. The tank is suspended on a rigid frame 69 from pontoons 71. 73 which float in liquid in a closed tank 53 and descend on guides 81 as the liquid is withdrawn through off take 67 at a rate controlled by valve 66. A layer of oil 63 floating on the surface of the water in the tank prevents evaporation. A vibrator is mounted on the bar 103 extending from the cross piece 95 supporting the plates and may be arranged to give a 60 cycle vibration to the plates. The water in the tank may be heated by burners 111, 113, 115 controlled by a thermostat attached to one of the floats. The process is described with reference to the crystallization of iodocinchonidine sulphate and three types of lacework crystal fields may be obtained by varying (a) per cent. saturation of solution, (b) temperature, (c) distance between plates, (d) relative movement between plates and solution. An equation showing the relation between the velocity of evaporation, the mass velocity, the temperature, and the solubility is given. Methods of controlling the alignment of the crystalline structure with respect to the plane of the solution surface are described. The crystalline films obtained are " intensified," i.e. the gaps in the mesh are filled in, by placing a plate covered with the film as described above on a table over which a super-saturated solution of the iodoinchonidine sulphate in water and ethyl alcohol is flowed. Several coats may be applied and the plate is finally sprayed with a jet of nitro-cellulose lacquer. Specification 450,090 is referred to.
