Filed: 1919-12-31
Abstract: 155,713. Sokal, S., (Maschinenwerk zu Frankfurt a/Main, vorm. Kolb, Rieber, & Co.). Dec. 31, 1919. Area meters.-In leather-measuring machines of the Sawyer type in which the registering arcs are operated by pinions lifted into engagement with them when goods pass under the feed wheels, means are provided for increasing the depth of such engagement and for disengaging the arcs and pinions. The usual lever 5 supporting the spindle 13 of the registering arc 4 is perforated as shown at c, d, e, f, so that the link 8 connecting it to the lever 3 carrying the spindle of the feed-wheel 1 may be attached at different points thus varying the depth of engagement between the pinions 2 of the feed-wheel and the arc. A turn-buckle inserted in the link 8 gives further adjustability. Two holding pawls are fitted differing half a tooth of the arc in engagement and are both released simultaneously by a linkage 23, 22, from the arm 20 connected to the treadle chain 27. A link 29 simultaneously rocks a shaft 32 having an adjustable stop for rocking the lever 5 to disengage the arc 4 and its actuating-pinion. A pair of holding pawls 14, 15, Fig. 2, on the same spindle 16 may be employed.

Abstract: 982,382. Cigarette-making machines. AMERICAN MACHINE & FOUNDRY CO. Sept. 14, 1961, No. 33076/61. Heading A2C. To convert a non-uniform tobacco stream 10 into a uniform stream first the density, and then the dimensions, of the stream are made uniform. The non-uniform stream 10 is trimmed to a uniform cross-section by a trimmer 14 and the density of the stream then measured by a detector 20. A control mechanism 22 operates in response to the signal from the detector 20 to operate an arm 32, having a compacting shoe 34, which presses on the stream to make the density uniform. The uneven, but uniformally dense, stream is then trimmed to uniform cross-section by a second trimmer 35. In an alternative arrangement the trimmer 35 may be arranged to rotate in the same direction as the stream travels and the arm 32 may have a bifurcated end, the trimmer being positioned between the bifurcations. Specification 780,108 is referred to.

Title: Improvements in or relating to electric discharge devices
IPC: H01J19/00
Filed: 1956-10-30
Abstract: 823,095. Making grids for electric discharge tubes; angular bending. M-O VALVE CO. Ltd., GORE, D. C., and WIDDOWSON, A. E. Oct. 30, 1957 [Oct. 30, 1956], No. 33150/56. Classes 83 (2) and 83 (4). [Also in Group XL (a)] The apparatus used for manufacturing electric discharge tube grids as described in Specification 741,621, is modified for producing grids (e.g. control and screen grids) whose wires have to be in alignment after assembly of the electrode structure. Fig. 3 shows an apparatus similar to that of Fig. 1 of the prior Specification, the method of manufacture of the grids being generally similar to that previously described. Between the pairs of threaded nickel tubes 37 are mounted pairs of accurately machined cylindrical pegs 39 perpendicular to the grid wires. The grid frame 1 is extended at one end into accurately dimensioned locating sockets 8, 9 which engage with the pegs 39. The grid wires are then wound and brazed in position as previously described. A further grid is subsequently manufactured in the same position, its locating sockets engaging with the same two pegs, so that its grid wires will fall in exactly the same positions as the wires for the first grid. In assembling the electrode structure, two ceramic rods, corresponding in size and position to the locating pegs, pass through the respective locating sockets of the grid frames, so that the grid wires are automatically in alignment. One of each pair of pegs 39 is eccentrically mounted on a block 40 having an actuating arm 41, so that the peg can move in a direction transverse to the grid wires. A fine adjustment can be made by a threaded rod (not shown) passing through hole 42 to engage against arm 41. To test whether the axes of the pegs 39 are in a plane parallel to the grid windings 43, a method of testing with a master grid is described. In view of the very close inter-electrode spacings required, it is necessary to bend the central part of the grid frame out of the plane of the grid wires. Fig. 4 shows a press for performing this operation; 6 and 7 are the sides of the grid frame, across which are stretched the grid wires 44. Spacing strips 45 are attached to the frame sides. The lower die block 47 has a raised platform 49 on which the grid rests. The upper die block 48 carries two cylindrical punches 50 (only one shown) which are sliding fits within cavities 51. The upper part of each punch consists of compressible rubber pads 55 between metal plates 56 and 52. On pressing down die block 48, a small projection 57 on the punch 50 makes contact first with the grid frame, and is pressed into it. The the shoulder 59 engages the side of the frame and bends it downwards (Fig. 5, not shown), at the same time reducing strip 45 to a predetermined thickness. The grid is reversed, and the other side similarly bent. Specifications 684,846, [Group XXIV], and 789,904 also are referred to.

Title: Improvements in kathode ray oscillographs
IPC: G01R13/20
Filed: 1922-12-06
Abstract: 212,305. Ramsay, F. R. F. Dec. 6, 1922. Electromagnetic current and pressure meters; electrostatic meters. - In a cathode-ray oscillograph the ray is deflected by two forces acting at right-angles, one being proportional to the instantaneous value of the current or electromotive force under examination, and the other being proportional to the instantaneous value of the rate of change of this quantity. In the construction shown the current to be measured is passed through two stationary coils F arranged in parallel with one another outside the cathode-ray tube D so as to deflect the ray proportionally to the current. A deflection of the ray at right-angles to this and proportional to the rate of change of the current. is obtained by the electrostatic field between a pair of plates G arranged inside the tube D and connected, either directly or through an inductive coupling, across the coils F. In another construction two pairs of plates at right-angles to one another are arranged inside the tube D, one pair being connected across a non-inductive resistance, either directly or through a transformer and the other pair being connected across an inductance in series with this resistance, either directly or through an inductive coupling. In another modification a condenser and a non-inductive resistance are arranged in series in the current circuit, one pair of plates being connected across the condenser in series with a small variable condenser and the other pair being connected, either directly or through a transformer, across the resistance.

Abstract: 1397201 Automatic control of dynamoelectric machines SIEMENS AG 16 July 1973 [14 July 1972] 33832/73 Heading G3R  In an A.C.-D.C.-A.C. frequency changer connected to an A.C. electrical machine, the current in the D.C. link is controlled according to the sensed current in the link and the machine torque. As shown, an asynchronous machine 2 e.g. driving a rail vehicle, is fed from a 3-phase supply 5 via rectifier 7, D.C. link 8 and inverter 6. The current is controlled, by control of rectifier 7 in synchronism with the supply, according to the difference between the link current I, sensed by current transformer 10, and a speed dependent current reference I* as modified by the machine torque error. This error #D is obtained by differencing the absolute values of a speed dependent desired torque D* and the actual machine torque D measured directly or (as shown) as calculated from the measured machine voltage and current. The torque error is also used to modify the desired speed value n", which is compared with speed dependent signal n from machine driven tachogenerator 4, any difference being used to control the machine speed by control of frequency of inverter 6. The desired torque may, alternatively, be constant e.g. set on a potentiometer. The system is said to smooth the torque to, or from, the machine when it is generating or motoring respectively.

Title: Method for producing cyanomethyl esters of organic acids, particularly n-acylated amino acids or peptides with configuration retained
Inventor: RZESZOTARSKA BARBARA
IPC: C07K1/08
Filed: 1965-08-09
Abstract: Cyanomethyl esters of carboxylic acids are prepared with retention of configuration by treating the acid with bromoacetonitrile in the presence of a tertiary amine.  The process is especially applicable where the carboxylic acid is an N-acylated amino acid or peptide.  In a comparative experiment, chloroacetonitrile is employed in place of bromoacetonitrile and gives rise to a product having less retention of configuration. The dipeptide phenylalanine-valine is prepared from the cyanomethyl ester of N-formyl-L-phenylalanine and the tert.butyl ester of L-valine.
