Title: Pulse generator
Inventor: SITTIG KONRAD
IPC: H03K3/282
Filed: 1967-09-26
Abstract: 1,149,135. Transistor pulse generators. STARKSTROM-ANLAGENBAU KARL-MARX. STADT VEB. 26 Sept., 1967, No. 43670/67. Heading H3T. In a pulse generator having a sawtooth Schmitt trigger generator I with a variable time constant R.C. integrating network R1/I, C1/I feeding via an impedance transformer II a further Schmitt trigger III, the Schmitt trigger III has its common emitter resistor replaced by a transistor T8 which has its collector current adjustable to a constant value by means of a voltage divider III.1 and the base of the output transistor T7 of the Schmitt trigger III is connected to a potentiometer III.2 for adjustment of the pulse duration to space ratio. When the supply E.M.F. is connected the potential at B rises negatively due to C1/I charging and when a certain value is reached the Schmitt trigger circuit I.1 changes state, T2 turns ON and T3 turns OFF. The negative going output at C is coupled via Zener diode D1 to the base of T4 which together with T5 turn ON so that the capacitor C1/I is discharged via T5. The trigger circuit I.1 then assumes its initial state and the above operation is repeated. When the sawtooth voltage produced at B reaches a certain value the Schmitt trigger III changes state T6 turns ON and T7 turns OFF. T6 remains on until the sawtooth voltage falls in value when the trigger circuit III returns to its initial state. This process is repeated to produce a pulse output at D of constant amplitude, the duration to space ratio being set by the adjustment of III.2. Zener diode D2 maintains the potential at G constant.

Title: Transistor storage cell
IPC: H03K3/356
Filed: 1968-09-13
Abstract: 1,237,288. Matrix stores. RCA CORPORATION. 13 Sept., 1968 [15 Sept., 1967], No 43671/68. Heading G4C. [Also in Division H3] A bi-stable circuit in a matrix store comprises two branches, each including two complementary transistors (shown as field effect transistors) in series, the interconnection in each branch being connected to the input electrodes of the other branch and the circuit being set by signals applied to one end of both branches. Setting is thus effected at high impedance points. In one state Q2 and Q3 are on, the " on " transistor carrying only the leakage current for the other transistor of the branch. The conducting states are reversed by reducing the potential at Y to - 4 volts and increasing that at X to + 4 V. The - 4 volts is transferred through Q2 to the gates of Q1 and Q3 switching on Q1 and reducing the bias on Q3 so that by regenerative action the change of state occurs. During the change both transistors become momentarily conductive and this for one direction of change is detected by a transistor 24 which thus provides a basis for destructive readout. Non-destructive read-out is effected by a smaller input at X and Y e.g. raising Y to + 2 V. and lowering X to - 2 V. If. Q1 and Q4 are " on", point A is thus lowered by its - 2 V. and Q2 becomes forward biased by 4 V. This provides a current through Q2 and Q1 to the output transistor but does not change the state of the circuit. Diode 14, which provides a load similar to the emitter-base path of 24 may be replaced by a further output transistor or omitted, in which case 12 and 18 may be dissimilar. Fig. 3 shows an integrated matrix store formed from such circuits with one bipolar output transistor for the whole store and with load 63 formed separately. Setting, destructive and non-destructive read-out are effected by changing oppositely the voltages on the X and Y lines, as described above.

Title: Improved means for adjusting the rollers of cold-rolling pilgrimming mills
IPC: B21B21/00
Filed: 1969-09-04
Abstract: 1,240,945. Rolling tubes. MANNESMANNMEER A.G. 4 Sept., 1969 [4 Sept., 1968], No. 43740/69. Heading B3M. A cold rolling pilgrim mill is provided with a reciprocable roll stand whose rolls 1 are rotated by the engagement of pinions coupled to the roll ends with fixed racks 2, the racks being movable from their fixed positions to allow adjustment of the rolls. Each roll is provided with two grooves in its periphery, each extending through 180 degrees. When the groove in use becomes worn, it is replaced by the other groove by rotation of the roll through 180 degrees relative to the rack. This relative movement can simply be arranged by unclamping a rack 2 of sufficient length and shifting it axially until the roll has rotated through 180 degrees. Alternatively, a wedge 3 which is used to adjust the meshing clearance between the rack and pinion can be shifted until the rack is moved out of mesh with the pinion. The pinion can then be rotated as desired. In a further form, Fig. 3, each rack is laterally movable out of engagement with the associated pinion by screws 6.

Title: Radiation shielding
IPC: G21F1/08
Filed: 1967-09-28
Abstract: 1,200,926. Radiation absorbing materials. CHEMTREE CORP. 28 Sept., 1967 [30 Sept., 1966], No. 44168/67. Heading G6R. A radiation shielding composition comprises a compound of one or more metallic elements with an atomic number from 57 to 71 inclusive (rare earth elements). The carbonates of these metals, in powder form, may be used in which case they are mixed with water to a paste consistency and formed into a desired shape, whereupon they set upon standing into a structural material comparable in strength to wall plaster. A highly effective neutron shield is obtained by combining dysprosium carbonate and gadolinium carbonate in this manner, the dysprosium and carbon acting as moderators with the gadolinium capturing the neutrons after reduction to thermal energy. Against a high energy flux the materials may be laminated with dysprosium carbonate for the source face layer, followed by a layer largely of dysprosium carbonate with some gadolinium carbonate, a layer of equal parts, a layer largely of gadolinium carbonate with some dysprosium carbonate, and finally a layer entirely of gadolinium carbonate. Such a laminate may be used to advantage for shielding space vehicles and missiles. Combination of the carbonates with lead powder is desirable in some cases because addition of the lead powder improves the structural characteristics and also adds the attenuating properties of lead. The metallic elements may be in the form of the carbonate of a mixture of rare eath elements as contained in an ore concentrate or tailings. Where gadolinium oxide is used, admixture with lead powder is essential if good setting is to be obtained.

Abstract: 1464030 Image intensifier tubes; ion sources PHILIPS GLOEILAMPENFABRIEKEN NV 15 Oct 1974 [17 Oct 1973] 44613/74 Heading HID [Also in Division C1] A display tube includes a photocathode having an emissive surface in the form of an array of concave recesses 4, 5, 6, 7 facing and aligned with a closely adjacent channel multiplier plate 2 such that with the operating voltage applied between the photocathode and the entrance surface of the channel plate, the electron stream from each recess is focused at the entrance of its corresponding multiplier channel 8, 9, 10, 11, whereby to improve the resolution of the image produced on the fluorescent screen 3. The glass substrate for the photocathode may be constituted by a fibre bundle light guide, cut from the same fibre bundle as the channel plate, the fibres having a core glass which is more readily etchable than the surrounding glass, to permit formation of the depressions by slight etching. Photographic (see Division C1) and sputtering methods of producing the depressions, using the channel multiplier plate as an optical collimator, and as an ion source, respectively, are also described. In the sputtering method, Fig. 2, the channel plate 22 is mounted opposite the glass slab 21 in a chamber filled with argon, and a high potential is applied across the faces of the plate, to produce positive ions therein which issue as a corresponding plurality of beams directed at the glass plate to induce sputter etching thereof. When assembling the tube, the end face forming the photocathode may be liquid sealed to the tube body, e.g. using gallium, permitting subsequent transverse relative movement to produce exact alignment of the photocathode with the channel multiplier plate, as judged by a microscope, whereafter the end face and the tube body are rigidly secured together using a setting resin or cement.

[Also in Division A2] Apparatus for sampling and measuring physical characteristics, e.g. parameters, of discrete objects, particularly biscuits, comprises means, such as the upper flight of an endless, travelling conveyer 12 Fig. 2, for conveying a plurality of streams of the objects; a sampling line, e.g. an endless travelling conveyer 14, or a plurality of, e.g. three, conveyers in series, for continuously withdrawing at least one stream of objects as a sample stream from said plurality of streams; means, such as a photocell counter 30 controlling a gate 32, for selecting a number of objects from said sample stream and means, such as a shoot 34, for returning objects which are not selected to the conveying means at a point downstream of the position where the sample stream is withdrawn, said downstream point being also located so that returned objects take up vacant spaces on the conveying means created by withdrawal of objects by the sampling line; means for measuring at least one physical characteristic of at least one object in the selected number of objects, and means such as a gate 58 and shoot 60, co-operating with said returning means for non-selected objects, for returning selected objects to said downstream point at an instant when non-selected objects are not being returned to the conveying means. Examples of physical characteristics which may be measured by the apparatus according to the invention are: the length, width or diameter of a single object; the overall length of a plurality of objects arranged in line with their edges touching; the colour of an object; the height of a single object or a stack of objects; the weight of a single object or a plurality, e.g. stack, of objects. For example a gate 40, Figs. and 5, may be actuated to allow a number of sampled objects to pass to a clockwise rotating wheel 46, which forms the objects into a stack on the rails 48 of a weighbridge 50. The stack is compacted by a member 52 sliding along the rails 48. The length (height) of the stack is measured by a transducer 54 associated with the member 52. The weight of the stack is measured by transducers associated with the weighbridge 50. The wheel 46 is then rotated counter-clockwise to unstack the tested objects, and return them, through a shoot 56, to the conveyer 14. A colour comparator 44 associated with a colour reference source may be located before the gate 40, or before the gate 58, to assess the reflectance and colour of an object. A gate 38 controlled by a photo-cell counter 36 may allow ten sampled objects to be lined up, in edge-toedge contact on a tilted part of the conveyer 14 before the gate 40, to intercept parallel beams of light directed on to a line of photo-cells and thus provide a measurement of the length of the ten objects.
