Patent GB-883319-A (GB)
Title: Improvements in or relating to the production of cyanamide
IPC: C01C3/16
Filed: 1958-10-02
Abstract: In a process for producing cyanamide in which calcium cyanamide is subjected to a carbon dioxide neutralization process to produce a dilute aqueous solution of CN.NH2, the Ca ion content of the solution is subsequently reduced to less than 0,2%.  The reduction of the Ca ion content permits the solution to be concentrated without hydrolysis and dimerization of the CN.NH2.  A slurry of CaCN2, in water, or an aqueous solution obtained by extracting CaCN2 with water, is neutralized with CO2 at atmospheric or elevated pressure, and precipitated solids are separated.  CO2 treatment of the filtrate may be repeated.  The filtrate is passed upwardly through a bed of cation exchange resin, e.g. of carboxylic acid type, to effect the Ca ion removal.  The resulting solution may be concentrated at above 40 DEG C., e.g. 70 DEG -90 DEG C., to produce a solution of 70-90% from which crystalline CN.NH2 may be obtained on cooling, or under reduced pressure almost to dryness to obtain crystals.

Title: Improvements in or relating to platen presses for working sheet material
IPC: B26D5/08
Filed: 1959-09-16
Abstract: 890,132. Cutting-out presses. BOBST & FILS S.A., J. Sept. 16, 1959 [Sept. 16, 1958], No. 31623/59. Class 31 (1). [Also in Groups XVI and XXIV] A toggle-actuated platen cutting-out press has two operating speeds and means allowing it to pass automatically from one to the other speed in the course of each working cycle so that the slow speed is engaged during at least a part of the impression dwell of each cycle and the fast speed outside that period. The press has a fixed upper platen 2 and a vertically movable lower platen 4 actuated by toggle levers 5. The toggle levers are connected to eccentric portions of a main shaft 7 by connecting rods 6. The shaft 7 is driven through a worm and pinion arrangement 10, 11 from a shaft 9, a fly wheel 8 connected to the shaft 9 being driven by a motor (not shown). One rotation of the shaft 7 effects a complete cycle of the press. The flywheel 8 is rotatably mounted on the shaft 9 and has integral therewith a clutch plate 17 and a gear 16. The plate 17 can be clutched electromagnetically by means of a coil 24 to a clutch plate 18 keyed to the shaft 9. The gear 16 meshes with a gear 19 integral with a gear 20. The gear 20 meshes with a gear 21 freely rotatable on the shaft 9 and connected to a clutch plate 22 which can be electromagnetically clutched by means of a coil 25 to a clutch plate 23 keyed to the shaft 9. The number of teeth on the gears 16, 19, 20, 21 is such that the ratio of the speeds of the gears 16 and 21 is four to one. Thus if the flywheel 8 is driven at 2400 revolutions per hour and the clutch 17, 18 is engaged, but not the clutch 22, 23, the press will operate at a speed of 2400 cycles per hour. If the conditions of the clutches are reversed the press will operate at 600 cycles per hour. Cams on the main shaft 7 operate an electric control system for the clutches 17, 18 and 22, 23 in such a way that during the period when the platens are actually making an impression the press runs at 600 c.p.h. while at all other times it runs at 2400 c.p.h. The press may be run continuously at 2400 c.p.h.

Title: A manufacture of polynuclear cyclic alcohols
IPC: C07J75/00
Filed: 1935-11-16
Abstract: Polynuclear cyclic alcohols are prepared by a modification of the process of the parent Specification which comprises oxidizing a polynuclear cyclic ketone obtainable as described in Specification 435,563 to a diketone and then reducing in acid, neutral or alkaline solution this diketone to the corresponding di-alcohol.  The process of the present invention furnishes a convenient means of obtaining the hydrogenation product of epi - oxy - aetioallocholanone-(17) which has a high physiological activity.  Since sterols of the epi-series do not occur in nature and it has been found advantageous to apply epimerization to the final product rather than to the parent material.  In an example, 3-oxy-aetio-allocholanone-(17) is oxidized with chromium trioxide in glacial acetic acid solution, and the 3 : 17-dioxo-compound so produced is hydrogenized in alcohol using a platinum oxide catalyst to yield 3-epi-oxy-aetio-allocholanol-(17).

Title: Time-division multiplex telecommunications exchange systems
Inventor: SCHLICHTE M
IPC: H04Q11/04
Filed: 1971-07-08
Abstract: 1313229 Time division multiplex exchange systems SIEMENS AG 8 July 1971 [21 July 1970] 32059/71 Heading H4K The switching of channels between N multiplex highways is effected by gating each channel to a bus-bar corresponding to each highway, each such bus-bar having a store for the channel data and the bus-bars being interconnected by log 2 N switching stages of N/2 switches per stage, the stages being operated, to provide bothway transfer of data between bus-bar stores, in a cycle of the first stage to the last stage and back again to the first stage, the pattern of interconnections between bus-bars in the stages being such that data received on any incoming channel can be switched by the last stage of a channel switching cycle to the store of the busbar of the wanted outgoing highway. Existing patterns of switching may be rearranged to avoid congestion. A single wire system is sufficient to switch delta modulated channels. For pulse code modulation the bus-bars are comprised of multi-wire cables to transfer the codes in parallel. As shown in Fig. 1, 16 highways MS1 to MS16 with GO and RETURN sections MSE and MSS, are interconnected by the four switching stages labelled I, II, III and IV. The first stage divides the bus-bars into two groups of 8 and connects corresponding bars of each group, bar VS1 being connected to VS9, VS2 to VS10, and so on. The second stage divides each of the groups of 8 bus-bars into sub-groups of four and connects corresponding bars of each pair of sub-groups. The third stage divides the sub-groups into groups of two bars each with connection between the corresponding bars of each such pair. The fourth stage provides connection between the pairs of the subgroups. An array of gates US1 to US16 takes incoming channel data, switched previously on to storage capacitors K, and transfers the data to storage capacitors C terminating the bus bars VS, an 8-step cycle then ensues, under the direction of sequence circuit ZR and address registers U, in order to shuttle the data between capacitors C until every piece of incoming data is held in that capacitor corresponding to the wanted outgoing highway. The inter-bus-bar switches US are loss free bothway switches and can be resonant transfer gates. The operating cycle provides switching successively in the first to the fourth stage and then, in reverse order, from the third stage back to the first stage. An example is given of a switching pattern whereby, in one channel slot, bothway paths are switched through with the incoming channel of each bothway channel pair being switched the one to the other.
