Title: A machine for applying a sleeve to a packet
Inventor: SKIRDE BERNHARD
IPC: B65B43/30
Filed: 1965-09-30
Abstract: 1,048,508. Packaging. INSTITUT FUR SCHIFFBAUTECHNIK WOLGAST. Sept. 30, 1965, No. 41577/65. Heading B8C. An apparatus for inserting packets 8 in closure sleeves comprises a magazine of sleeves 1 which are fed one at a time on to a platform where suction arms 13 erect the sleeve, into which the packet 8 is moved after passing between guides 21 on a movable frame 20. The closure sleeves 1 are stacked in the magazine 2 and are released individually by a pair of separating devices 3. Each separating device 3 consists of a pair of vanes 6, 6<SP>1</SP> which are spaced along a spindle 7, Fig. 2 (not shown), by the thickness of a folded up sleeve and lie on opposite sides of the spindle 7. As the spindle 7 oscillates only one sleeve 1 is released at a time. The oscillations of the spindle 7 are effected by a pneumatic servo 5. Each closure sleeve 1 drops on to the platform 10, Fig. 2 (not shown), and is held by suckers 11 while suckers 16 on the suction arms 13 are lowered on to the sleeve by a parallelogram linkage 12 operated by a pneumatic servo 15. The sleeve 1 is then opened by retraction of the parallelogram linkage 12 and the suckers 16 at the same time as a thrust plate 18 is retracted by a scissor linkwork 19. The filled packet 8 is inserted in front of the thrust plate 18 and the movable frame 20 moved to introduce the guides 21 into the sleeve 1. The guides 21, which are in the form of spring-loaded plates, hinge outwards as the packet 8 is pushed into the sleeve 1 by the thrust plate 18 and are finally removed from between the packet and the sleeve when the frame 20 is withdrawn. The upper flaps of the packet are held closed by a plate 27 during the insertion. The sleeved packet is then pushed out by a reciprocating thrust arm 30, driven by a pneumatic servo 33, Fig. 2 (not shown), through sprockets 31, 32, and a chain 35. The servos are operated either pneumatically or alternatively hydraulically, and are controlled automatically by switches and pneumatically operated multiway valves.

Title: Electronic signal processing
IPC: H04N9/68
Filed: 1973-09-05
Abstract: 1419873 Television; pulse shaping circuits ELLANIN INVESTMENTS Ltd 5 Sept 1973 [5 Sept 1972] 41824/73 Headings H4F and H3P The transition time of a signal, e.g. a lowbandwidth chroma signal I or Q, is reduced by averaging selected samples of the signal from one side of the transition and then from the other side of the transition, the transition of a corresponding signal having a shorter transition time, e.g. the luminance component, being determined and used to switch the sample averaging from one side to the other side of the transition. In this manner the apparent band width at the transition of the chroma signals substantially equals the luminance signal and a sharp edge is produced between different coloured objects. In addition registration errors between the chroma components are visually corrected. In the embodiment described the luminance signal and the I and Q signals are supplied to respective chains of series-connected signal delay devices, the value of the luminance signal at the delay device chain to which it is applied being compared with the value at the other locations between the delay devices in the chain, and only the signal values of the I and Q signals at the corresponding locations of the delay device chains to which they are applied are connected to the respective output lines where no substantial difference is sensed between the compared luminance samples. If one I (or Q) signal value is blocked then all the I (or Q) signal values on the same side of and more remote from the delay device chain centre are also blocked. The gates or switches which are controlled to pass the chrominance signal samples are designed so as to be normally conducting and to gradually cut off as the difference sensed between luminance signal samples goes from zero to a few per cent of the maximum value of the luminance signal. The upper limit of the cut-off range is preferably chosen to lie slightly above the noise level so that the circuit also acts as a noise-reducing circuit. The circuit shortens the chroma transitions by actually lengthening the transition as a whole but shortening its centre portion. Special effects may be produced; e.g. cartoon like pictures, by using the luminance signal to control itself instead of a chroma signal and by raising the cut-off threshold.

Abstract: 1,214,391. Teaching machines. TESLA NARODNI PODNIK. 9 Sept., 1968 [9 Sept., 1967], No. 42811/68. Heading G5G. A teaching machine includes a student response entry keyboard, a control memory, e.g. a film, with cells containing information for display and for control purposes, one or more peripheral memories such as tape recorders, film projectors, and a unit for controlling the operation of the peripheral memories 10 and the shifting of the control memory in either direction. A student response entry a 1 -a k  and the corresponding signals g 1 -g k  from a cell of the control memory are compared, and depending on the result of the comparison, the film in the control memory may be driven forwards or backwards through a succession of cells until one bearing a particular control bit (h 5  or h 6 ) is reached. The system may then call for a further student response and may subsequently advance the control memory film in single cell steps. A control bit (h 7 ) on the cell arrived at any stage of the operation initiates operation of a peripheral memory 10, and this memory, on completion of a cycle of operation, may cause a further one cell advance of the control memory or a return to the initial state of the apparatus awaiting a further student response, depending on a control bit (h 8 ) in the memory cell at present in the display position. Other control functions, both internal and external, are provided. One of the response keys (a k+1 ) is for "interrogation" when the student is unable to decide which response a 1 - a k  to choose, and this, depending on a control bit (h 3 ) in the current control memory cell, causes the control memory to be shifted forward one cell or backwards through a succession of cells until one containing a control bit (h 6 ) is reached, so as to provide the student with a partial or complete solution or explanation. The keys a k+2 , a k+3  initiate forward and backward shifting of the control memory by one cell if corresponding control bits g k+2 , g k+3  are present, but shifting by arbitrary amounts may be allowed under certain conditions.

Title: Improvements in or relating to fuel for nuclear reactors
Inventor: STEELE BERNARD ROBERT
IPC: C01G43/025
Filed: 1963-10-30
Abstract: A nuclear fuel body of uranium dioxide, which is suitable for incorporation in nuclear reactor fuel elements, is produced by mixing uranium dioxide powder with powder of a higher oxide of uranium, compacting the mixed powders, and sintering the resulting compact in a reducing atmosphere.  The uranium dioxide, which is predominant in the mixture, is of a form which after compaction sinters to a high density.  The mixing of the powders is so limited that agglomerates of the higher oxide powder exist in a continuous matrix of the uranium dioxide powder, the higher oxide being reduced to dioxide prior to actual sintering and in so doing shrinking more than does the dioxide originally present, thereby producing a body of high-density uranium dioxide containing discrete regions of internal porosity.  Preferably, the surface area of the uranium dioxide is from 2 to 6 square metres per gram and of the higher oxide is from 0.5 to 12 square metres per gram, the higher oxide, which may be U3O8, UO3 or UO4, constituting from 5 to 30% by weight of the mixed powders.  Advantageously, the uranium dioxide has a natural U-235 content and the higher oxide is enriched in U-235.
