Filed: 1967-11-22
Abstract: 1,202,264. Producing concrete elements. B. BERGE. 22 Nov., 1967, No. 53238/67. Heading B5A. Concrete elements are formed by casting the correct amount of concrete between upstanding mould sides at a lesser separation than that required in the finished article, and pressing this preform downwards and outwards to the required shape. As shown, to form an element 8 the required amount of concrete 4 is first cast into a mould comprising a base 1 and upstanding side portions 2, 3; the separation between the portions 2, 2 and 3, 3 being less than the width of the final object. The first mould sides 2 and 3 are then removed and a second mould comprising sides 6 and an upper section 7 is placed over the preform. The upper mould section 7 is lowered by rams 10 and under vibration from vibrator 11 forces the concrete downwards and outwards to the dimensions of the element 8. Small gaps may be left in the top of the mould to permit expulsion of air. The apparatus may be used for line production, the moulds being raised on bar 14 and moved along to the next element.

Title: Tabletting machines
IPC: B30B11/12
Filed: 1973-11-17
Abstract: 1481797 Tabletting machine MANESTY MACHINES Ltd 11 Nov 1974 [17 Nov 1973] 53494/73 Heading B5A Granular material from a hopper 160 is fed into dies 30 spaced around a rotary cylindrical die table 32 and compressed into a tablet in each die between a pair of punches 38, 40 individual to the die, the punch 40 being subsequently withdrawn and the punch 38 pushed through the die to eject the formed tablet. The punches are slidable in flanges 36, 34 of the table and moved radially with respect to the axis of rotation 14 of the table; the outer punches 38 are moved under the control or radial deflections of a flexible hoop 52 rotating with the table and which is constrained and guided by rollers 54, 56, 58 so as to assume a non-circular shape. The rollers 54 are adjustable radially of the table axis to vary the quantity of material fed into the dies and the roller 56 is radially adjustable to adjust the thickness of the tablets. The heads of punches 38 are held in engagement with the hoop by a spring ring 60. The heads 42 of the inner punches engage in a circular cam track formed between freely rotatable concentric circular parts 44, 46 the axes of which are offset from the axis 14. After die filling, the punches are brought to their extreme compressing positions at the roller 56 and the outer punches are brought to the tablet ejecting position at the roller 58 where tablets are received by a shoot. A tablet is thereby produced by each die during a single revolution of the table; by using additional flexible hoop deflectors or rollers more than one tablet per die for each revolution may be produced. The hopper feeds the material to a stationary framework including spaced vertical walls which, at their lower edges, have a radial clearance with the surface 24 of the die table against which the material is centrifugally held. Material is deflected over the dies to fill them, and scrapers, not shown, deflect excess material to an annular channel 84 of the table. Such excess is re-deflected by the feed framework to join further material supplied by the hopper. The table axis could extend vertically; the machine may comprise two tables rotating about a common axis.

Title: Process for the isolation of cholecalciferol
IPC: C07C401/00
Filed: 1965-12-20
Abstract: In a process for the isolation of cholecalciferol from a mixture obtained by irradiation of 7-dehydrocholesterol and subsequent conversion of the precholecalciferol obtained into cholecalciferol, the cholecalciferol is precipitated as a cholecalciferol - 7 - dehydrocholesterol complex and the cholecalciferol is subsequently separated from the complex.  A solution of 7-dehydrocholesterol, e.g. in benzene, is irradiated with ultra-violet rays, the solvent is removed at reduced pressure, an alcohol, e.g. methanol, is added to precipitate unreacted 7-dehydrocholesterol, which is removed, the alcoholic solution is heated to convert precholecalciferol into cholecalciferol, 7-dehydrocholesterol is added to obtain a proportion by weight between the cholecalciferol and 7-dehydrocholesterol of 1:1, and the solution is concentrated under reduced pressure and cooled to precipitate the complex.  The complex is dissolved in benzene and passed through a column of active adsorbent, e.g. aluminium oxide, which is then eluted, first with benzene and then with a mixture of benzene and ethanol to obtain a fraction containing pure cholecalciferol.  An example is given.

Title: Mobile radio telecommunication system
IPC: H04W88/02
Filed: 1968-11-14
Abstract: 1,210,149. Automatic exchange systems; radio signalling. INTERNATIONAL STANDARD ELECTRIC CORP. 14 Nov., 1968 [17 Nov., 1967], No. 53995/68. Headings H4K and H4L. In a system for interconnecting mobile radio subscribers equipped with transceivers and/or call warner sets, with a wired exchange, the exchange employs a plurality of fixed radio telephone base stations, each associated with a different service channel upon which selective calls to mobiles are transmitted and with a different group of conversation channels, each transceiver being adapted in response to a selective call to tune to an available conversation channel in the group associated with the service channel on which the selective call was received. The network of fixed radio stations allows the system to cover a large area. Three sets of signalling frequencies are employed, with some non-adjacent fixed stations employing the same frequencies. Each fixed station employs a first frequency tone to mark its service channel, which is modulated with a work tone to effect dialling, and a second frequency tone to mark a free conversation channel as the one to be used for the next call. A transceiver having six. filters one tuned to each of the first and second tones of each of the three sets is detailed. When the transceiver is free it tunes to the service channel of a fixed station in its area and one of three bi-stables is set to characterize the set of frequencies employed. In the event of a call incoming to the transceiver. the transceiver responds to the recognition of its selective call signal by tuning to the marked conversation channel in that set, an AND gate enabled by the set bi-stable and connected to the filter tuned to that channel responding when the channel is scanned. In the event of a call outgoing from the transceiver it tunes to any conversation channel marked free by any fixed station in the area. If while tuned to a service channel the tone on that channel drops to an unacceptable level a supervisory device in the signaller of the transceiver causes the transceiver to search for another channel. The transceivers use different seizure signals when seizing a conversation channel for terminating and for outgoing calls allowing the exchange to refuse seizure of a channel required for use in a terminating call to transceiver initiating an outgoing call.
