Patent GB-926513-A (GB)
Title: A printing mechanism for electronic counters
Inventor: MULLER HANS EBERHARD
IPC: G06C11/00
Filed: 1960-02-26
Abstract: 926,513. Selective printing. BUCHUNGSMASCHINENWERKE KARL-MARX-STADT VEB. Feb. 26, 1960, No. 6825/60. Class 100 (4). [Also in Group XXXVIII] An adding machine is modified for printing numbers registered in an electronic counter. Each number is printed as two or more groups of digits, the digits of each group being printed in parallel but the groups being printed successively and the paper carriage being tabulated in between so that the groups are printed side by side. Negative numbers registered as complements are converted into their true form by using the machine's  totalizer. The digits of the first of two groups of digits making up a positive number are read from the electronic counter by applying ten pulses to each order of that group in synchronism with the rotation of a shaft 40, Fig. 2, frictionally driving segments 35 and applying the carry pulses to solenoids 43 to raise slides 42 so as to arrest the segments 35 in differential positions corresponding to the complements of the digits registered in the electronic counter. Wheels 28 are then disengaged from the segments 35 and engaged with racks 88 of the adding machine, Fig. 1. A cycle of the latter is then initiated under the control of the read-out mechanism and the wheels 28 are driven further by the racks 88 until projections 90 abut against stops 29. The racks 88 and type bars 61 coupled to them are thus set in accordance with the digits registered in the electronic counter and those digits are printed in known manner. The carriage then tabulates and closes a pair of contacts in its new columnar position so as to cause a further cycle of the read-out mechanism, Fig. 2, again followed by operation of the adding machine so as to print the second group of digits. When the number registered in the electronic counter is a negative number in complementary form, a signal from the counter energizes a magnet Mg, Fig. 3, which so conditions mechanism actuated by the read-out mechanism that the latter rocks a shaft 22 in the adding machine from a first normal position to a second position in which it sets the machine for addition and also blocks operation of the printing, line-spacing and tabulating mechanisms. Also mechanism, Fig. 4 (not shown), is conditioned to cause a further cycle of the adding machine following its first cycle and to cause the control shaft 22 to move to a third position, in which its sets the machine for total taking and also rocks a negative control member 39. During the first cycle, the complement stored in the electronic counter is entered into the totalizer 63. During the second cycle, the amount is printed correctly as a negative total. This procedure is repeated, as in the case of a positive number, for each group of digits.

Title: Spinning and twisting apparatus
IPC: D01H9/02
Filed: 1961-02-24
Abstract: 904,840. Winding reserve-lengths. CHEMSTRAND CORPORATION. Feb. 24, 1961 [March 11, 1960], No. 6923/61. Class 120 (2). In spinning &c. apparatus, to facilitate the transfer of the yarn to a fresh bobbin without interrupting the delivery of the yarn, a transfer spool is rotatably mounted on the spindle, and the traverse-means is movable to direct yarn on to the spool, means being provided for rotating the spool at a speed different from that of the spindle, so that the yarn between the bobbin and spool is severed by cutting-devices provided on the spindle and spool. In the case of a ring- twister, Fig. 1, a transfer spool 30 is frictionally mounted by bearings 32 on a spindle 14 and has an upper flange with cutting-spurs 34, and a friction-ring 34. A spindle-wheel 22 has a flange 26 with cutting-spurs 28 and a brake 25. A roller 44, Fig. 2, carrying a disc 38 and driven by a belt 72 passing around an idler 74 is carried by a shaft 46 mounted eccentrically in a base 50 in a recess in a base-plate. Shaft 46 carries a handle 64 which in position B takes the disc 38 out of contact with ring 34 on spool 30, it being held in this position by a stop 82. When the stop is depressed against spring- pressure, the handle 64 is pulled to position A by a spring 68 so that shaft 46 is rotated to bring the disc and ring into engagement. When winding is taking place, the mounting of spool 30 on the spindle allows the two to rotate together. When the bobbin is filled, the ring-rail is lowered to a position where it surrounds the spool 30 so that a few turns are wound thereon ; handle 64 is now moved to position A so that the ring 36 engages the disc so that the bobbin and spool rotate at different rates, so that the cutters 28, 34 likewise rotate at different speeds to sever the yarn between the bobbin and spool. The spindle is braked at 25, the bobbin is removed and replaced by an empty one, the ring-rail is moved to normal starting position, and the spindle-brake is released. The yarn now falls across the flanges 34, 26 and is severed by the cutters, whereupon lever 64 is moved to position B to disengage disc 38 from the spool, the upper face of stop 82 being shaped to allow the lever to slide past the stop. The belt 72 and the disc 38 and associated parts are enclosed by a protective cover 96.

Title: Improvements in or relating to maser and laser systems
IPC: H01S1/02
Filed: 1964-02-20
Abstract: 1,044,724. Semi-conductor devices. SIEMENS & HALSKE A.G. Feb. 20, 1964 [Feb. 21, 1963], No. 7065/64. Heading H1K. [Also in Division H3] A semi-conductor laser or maser body is stressed to modify its output. A semi-conductor crystal having a PN junction region is arranged between two flat, parallel plates and a stress is applied by a tensioning screw bearing on one plate. The stress splits a degenerate multiplet level into separate terms, giving an increase in bandwidth, whereas singlet levels are simply shifted to vary the output frequency. To increase the bandwidth from a crystal having only singlet terms a non-uniform stress may be applied by using plates which are not flat. In Fig. 2 a non-uniform stress is produced by bending a semi-conductor bar. Light passes along line 23 and is reflected at surface 24. If reflection at the interface between junction layer 22 and crystal body 21 is necessary, the main body may be so heavily doped that metallic reflection occurs. Additional pumping may be provided by electromagnetic radiation 27, supplementing charge carrier injection. Layer 22 may include a plurality of PN junctions, regions of like conductivity type being connected to common D.C. terminals, or the outermost layers only being connected to an A.C. source so that the intermediate layers constitute capacitor junctions in series with laser junctions.

Patent GB-570374-A (GB)
Title: Chlorination of unsaturated alcohols
IPC: C07C31/34
Filed: 1943-05-05
Abstract: Polychlorinated alcohols are produced by chlorination of an unsaturated alcohol containing an olefinic linkage between two carbon atoms of aliphatic or cycloaliphatic character in the presence of such an amount of a concentrated aqueous hydrogen chloride solution or an approximately saturated aqueous solution of a relatively soluble metal chloride that the number of molecules of hydrogen chloride or metal chloride exceeds the number of molecules of the unsaturated alcohol in the reaction mixture throughout the reaction. Allyl alcohol yields glycerol 1,2-dichlorhydrin.  Allyl-type alcohols of the formula <FORM:0570374/IV/1> where R is hydrogen or an alkyl, aryl, aralkyl, alkenyl, aralkenyl, alicyclic or heterocyclic radical which may be further substituted, may also be reacted, e.g. methyl vinyl, vinyl ethyl, vinyl propyl, vinyl butyl, vinyl pentyl, butenyl, pentenyl, hexenyl, styryl, styryl methyl, styryl ethyl, styryl propyl, styryl phenyl, styryl benzyl, vinyl benzyl, and vinyl phenyl carbinols, crotyl alcohol, and D -2,3-cyclopentenol, -hexenol, and -heptenol.  Chlorination is effected below about 40 DEG  C. and, for allyl alcohol, preferably at about -30 DEG  to 0 DEG  C.  The concentration of chloride ion is increased with rise of temperature, and an approximately saturated solution is preferably used in such quantity that the number of molecules of hydrogen chloride or metal chloride is several times the number of molecules of alcohol.  A batch, intermittent or continuous process can be used at any pressure at which the alcohol remains liquid. Glycerol dichlorhydrin may be separated from the product by a selective solvent, e.g. diethyl or other ether, hydrocarbons, higher alcohols or petroleum ether. Hydrogen chloride should first be removed by extraction with a non-polar solvent, e.g. a hydrocarbon or chlorinated hydrocarbon, or neutralized with a basic compound of, for example, calcium, magnesium or aluminium such as calcium carbonate, the calcium chloride formed salting out the dichlorhydrin as a nonaqueous layer.  The aqueous phase may be recycled.  In examples, a mixture of allyl alcohol with concentrated hydrochloric acid or calcium chloride solution is maintained at about 20 DEG  C. in an ice bath while chlorine is bubbled through.  The product, in the former case after neutralizing with calcium carbonate, is extracted with ethyl ether and the dichlorhydrin recovered.
