Filed: 1938-02-14
Abstract: 511,430. Aminonitriles. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.). Feb. 14, 1938, No. 4556. [Class 2 (iii)] alpha-Dimethylaminoacrylic acid nitrile is manufactured by causing dimethylamine to act upon a #-halogenacetaldehyde cyanhydrin, which may be in the form of an aqueous solution obtained by the action of an equimolecular proportion or an excess of hydrocyanic acid on a halogenacetaldehyde in the presence of water and a feebly alkaline agent. The product is an intermediate for pharmaceutical purposes, for adjuvants in the textile industry and for making artificial materials. On treatment with water it yields dimethylacetamide, which compound -may also . be formed as a by-product of the reaction. In examples :-(1) an aqueous solution of dimethylamine is added gradually with stirring to an aqueous solution of alpha-hydroxy-#-chloropropionitrile (obtainable by reacting #-chloracetaldehydewith anhydrous hydrocyanic acid in the presence of potassium cyanide) ; (2) a solution obtained by stirring chloracetaldehyde and hydrocyanic acid in water in the presence of a feebly alkaline agent, such as an alkali cyanide, e.g., potassium cyanide, or an alkali carbonate, is added gradually to an aqueous solution of dimethylamine.

Title: Improvements in or relating to change-speed gearing
IPC: F16H61/02
Filed: 1929-02-12
Abstract: 306,139. Holmgren, S. A. Feb. 16, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Variable-speed gearing. - Comprises a separate friction clutch for each speed put into action selectively by a governor 42 driven from the driven shaft 21. There are four countershafts 6, 7, 8, 9 for three forward speeds and reversed driving, each shaft being adapted when moved to the right of Fig. 1 by a spring 25 to put in a friction clutch 22 between the selected shaft and a gear 16, 17, 18, or 19 upon it. The gears 16 - - 19 are constantly in mesh with a gear 20 fast on driven shaft 21. The shafts 6 - - 9 are geared to a driving-shaft 1 by pairs of different ratio with a reversing idler 14 in the case of shaft 9. The springs 25 press upon plates 24 fast on the shafts 6 - - 9. Normally an annulus 26 retains all the plates 24 so as to maintain all the clutches 22 inactive. The governor 42 acts through a gear train 30, Fig. 3, to turn the annulus 26 so as to bring gaps 44 opposite the plates 24, and so allow the shaft 6 - - 9 corresponding to be thrust by its spring to engage the clutch 22 upon it. The annulus 26 may alternatively be turned manually.

Title: Improvements in or relating to apparatus for winding web on and unwinding web from aspool
Inventor: KLEMENT FRANZ JOHANNES
IPC: G11B15/32
Filed: 1957-02-12
Abstract: 878,009. Feeding magnetic tapes. ELECTRIC & MUSICAL INDUSTRIES Ltd. Feb. 6, 1958 [Feb. 12, 1957], No. 4708/57. Class 40 (2). [Also in Groups XVI and XXIV] An apparatus for winding and unwinding a magnetic tape 1 from a spool 2 comprises a shaft 6 for carrying the spool, means for driving the shaft in one direction to wind tape on the spool, means for unwinding tape from the spool, the driving means being inoperative to drive the spool when the unwinding means is operative to unwind tape from the spool and a torsionally resilient coupling between the shaft and the driving means, the arrangement being such that when the unwinding means is operative, to unwind tape the coupling is stressed and when the unwinding means is inoperative the coupling tends to rotate the spool to wind tape thereon, thus tensioning the tape between the spool and unwinding means. The web 1 is unwound from the spool 2 by a capstan roller 4. The spool 2 supported on a shaft 6, is coupled to a shaft 11 by a resilient coupling comprising spring fingers 7 on the shaft 6 engaging pins 8 projecting from a disc 9 carried by a sleeve 10 rotatable on the shaft 11. The sleeve 10 has a disc 12 fitted between felt rings 13 fitted between a driving flange 14 and a disc 15 urged together by springs 17 on pins 16. The flange 14 is rotatably mounted on the shaft 11 and is driven through a one-way clutch by a crank 18 having a crank-pin 19. The crank 18 has a boss 20 which is locked during clockwise rotation to an annular flange 23 on the flange 14 by balls 22 engaging inclined flats 21 on the boss 20. Thus, when the crank is driven clockwise, the drive is transmitted to the spool 2. When tape is to be unwound from the spool the crank is driven counterclockwise, the annular flange being held stationary by a pivoted arm 25 having a curved end 26. When the capstan roller is stopped the spool 2 tends to overrun thereby stressing the springs 7 which then cause reverse rotation to prevent slackness of the tape between the spool 2 and roller 4. The spool 3 may be driven in the same manner as the spool 2. Specification 878,008 is referred to.

Abstract: 737,696. Fluid-actuated valves. AVERYHARDOLL, Ltd. Feb. 15, 1954 [Feb. 19, 1953], No. 4716/53. Class 135. A liquid meter operated 'controlling means for a main valve 69 has a pilot valve 77, Fig. 1, held open by resiliently-loaded retaining means 39, Fig. 3, e.g. acting through a crank 31, link 59 and crank 61, 62, 78, and released for closing by movement of one element 33 of a screw and nut which is restrained against rotation by the retaining means, e.g. by a rod 32 on crank 31 engaging a lug 34 on nut 33, the other screw element 30 being driven by the meter 10, e.g. through bevel gears. 17, 18, clutch 19, cyclometer counter 22, pins 24, starwheel 25 and gears 27, 28, to rotate the screw until co-operating abutments 35, 37 on the elements engage and the crank 31 is turned by the meter to disengage the retaining means. As shown, a half revolution of a pin 24 corresponds to the flow of a unit quantity of liquid. A handle 48 is pushed in to engage and rotate a shaft 29 to screw the nut 33 a certain distance to the left along the screw 30 corresponding to the quantity of liquid to be delivered which is indicated by a counter 46, 47. A pump is started to supply liquid via pipe 14, the meter and valve inlet 64 so that liquid passes an orifice 73, behind a main valve piston 71, and orifice 76 to chamber 75. The crank 31 is moved manually to engage the detent 39 and open valve 77 so that pressure behind the piston is relieved via pipe 74 and the main valve opens. During delivery of the last unit quantity of liquid the engaged abutments 35, 37 through the rod 32 force the part 38 on crank 31 under the detent 39 so that a follower 43 pivoted on the crank rides a cam 44 which allows the pilot valve and the main valve to close gradually until a complete cut-off occurs at a point 45 on the cam when the last unit finishes.

Title: Improvements relating to the production of alkylated thioureas and alkylammonium alkyldithiocarbamates
Inventor: KENDALL CHARLES EDWIN
IPC: A47G27/04
Filed: 1961-02-09
Abstract: Alkylated thioureas RR1N.CS.NRR1 and alkylammonium alkyldithiocarbamates RR1N. CS.S-RR1NH2+, wherein R and R1 are alkyl or cycloalkyl, or R1 may be H, are made by reacting together CCl4, a source of sulphide ions such as H2S or Na2S and the amine RR1NH. Generally, low temperature reaction using H2S and an inert non-aqueous solvent favours dithiocarbamate formation, while the use of Na or other alkali metal sulphide, water and somewhat higher temperatures favour alkylthiourea formation. In examples:-(1) reaction of CCl4, n-hexylamine, Na2S and water, the temperature rising to 76 DEG C., gave di-n-hexylthiourea and some n-hexylammonium n-hexyldithiocarbamate; (2) reaction of CCl4 and diethylamine in iso-octane with H2S at ordinary temperatures gave diethylammonium diethylthiocarbamate.

Title: Electrical signal-translating system
IPC: G06F11/00
Filed: 1961-02-09
Abstract: 894,248. Electric selective signalling systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 9, 1961 [Feb. 10, 1960], No. 4816/61. Class 40 (1). [Also in Group XL (b)] A system for automatically detecting, indicating and replacing a faulty component in logical circuits and for changing the logical function performed by the circuits includes a plurality of amplifiers 1-4, Fig. 5a, which are normally maintained in one signal translating condition, and a plurality of switching elements such as photo-contacts, which couple individual outputs of amplifiers 1-4 to individual inputs of the amplifiers, and are responsive to selectable patterns of applied control effects, e.g. illumination, to modify the signal translating condition of selected ones of amplifiers 1-4. Each amplifier 1-4 may form part of a NOR circuit, as shown in Fig. 2b, in which the transistor is normally biased to a non-conducting condition, but the negative bias is reduced and the transistor rendered conducting if one of the photocontacts # is illuminated. The NOR circuits may be interconnected to perform any logical function as desired by selectively illuminating the photo-contacts, for example by means of a pattern of holes or transparent areas in a card. film or tape. In Fig. 5a, amplifiers 1, 2, 3 are connected in a closed loop to form an oscillator whose output is taken from amplifier 3 on line 46 which is connected to line 49 through an illuminated photo-contact. If one of amplifiers 1, 2, 3 becomes faulty there is no input to amplifier 55, relay 57 operates to close contacts 58 and a pulse is transmitted to a pattern-shifting mechanism 43 which then advances card 29 in the direction shown by arrow 66 so that a fresh pattern of holes is selected, the function performed by amplifiers 1-4 being the same but with the faulty component replaced by another. For example, if amplifier 1 was faulty, amplifiers 2, 3, 4 may be connected in a closed loop, the output being taken from amplifier 4 on lines 45, 49. The system not only provides automatic replacement of faulty components, but may also indicate which component is faulty, e.g. by displaying a number on the side of the card showing which amplifier is not connected in the circuit. It is stated that the system may be used as a substitute for a plugboard in a computer, for example for controlling the arithmetic unit functions.
