Title: Safety device for nuts on bolts
IPC: F16B39/32
Filed: 1924-07-24
Abstract: 228,786. Jasper, C. H. July 24, 1924. Locking nuts; covers for nuts; nuts, tightening by vibration. - A lock-nut device comprises a protective cap having an internal coiled-spring secured thereto, one end of the spring engaging a slot in the bolt. The spring is given an initial tension and automatically takes up any slackness in the nut due to vibration. The cap 5, Fig. 1, has one end of a spring 3 secured thereto by a bridge-piece 9. the other end being bent to engage a slot 4 in the bolt 1. The spring is tensioned by turning the cap in a contra-clockwise direction, with the cap partially covering the nut. The cap is then pushed downwards until pins 7 on the nut 2 engage a bayonet groove 6 in the cap and secure the cap in position. Modifications in which the methods of engagement of the cap with the nut are varied are shown and described. In one the cap has an inwardly projecting flange, corresponding in shape to the outer periphery of the nut, which can turn freely in an annular groove at the base of the nut when tension is being applied to the spring, but engages the nut when the cap is subsequently raised. In another modification one end of the coiled spring is adapted to slide in an extended bridge piece 9, Fig. 3. and the spring is tensioned before the cap is pushed down into engagement with the nut. In a still further modification the inner end of the spring is gripped and drawn out axially until it is flush with the open end of the cap. It is then introduced into the groove in the end of the bolt and tends to draw the cap down as the spring is tensioned. The lower end of the cap in this case is adapted to snugly fit the nut. Fig. 5 shows a device for locking the cap to the nut. A ring 13 is placed between the nut and the inner wall of the cap. The wall of the cap 5 is provided with a hole 14 containing a spring-pressed ball 15. Any tendency of the cap to slack back is resisted by the ball 15. To release this lock, a nail &c. is inserted into a hole 19. In a modification of this locking device the ring 13 is omitted and the hole 14 drilled tangentially to the inner wall of the cap. In this case the ball engages a flat on the nut to lock, but rides over the flats when the coiled spring is being tensioned. The ball may be replaced by a roller, or by a spring-pressed pawl engaging ratchet-teeth on the ring.

Title: Devices for sensing punched cards or the like
IPC: G06K7/08
Filed: 1955-06-20
Abstract: 769,875. Statistical apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 20, 1955 [June 19, 1954], No. 17740/55. Class 106 (1). A sensing device for record cards or the like, e.g. having perforations, comprises one or more pairs of electrodes arranged to receive the cards between them and means for detecting changes in the electrical capacity between the electrodes. As shown in Fig. 1, the electrodes 2, 3 are connected with a balancing condenser 12 to the secondary winding of a radio-frequency, transformer so as to form a bridge. The centre of the transformer winding is connected to earth and the condenser 12 is chosen so that when the electrodes 2, 3 are registered with an imperforate part of the card the bridge is balanced and no voltage appears at point 13. When a perforation passes between electrodes 2, 3, the capacitance falls and a R.F. voltage appears at point 13. This voltage is applied through a coupling condenser 14 to the grid of a valve 15 for rectification and amplification. The voltage applied to the grid causes a change in the plate current. A circuit 17 tuned to the frequency of the source 7 is also connected to the condenser 14 and feedback is provided from the screen grid coupled to circuit 17 through coil 18. The plate of the valve 15 is connected through a commutator 21 with twelve segments to a sorting magnet 23 and a plate current source A. The commutator rotates in 'synchronism with the card feeding means. Each of the segments can be disconnected from the magnet 23 when desired and the machine will then operate as though corresponding card perforations were not present. The electrodes 2, 3 are shielded from external influences by rings 4, 5 connected to earth. Where electrodes are provided for each of a number of card columns they may be arranged as shown in Fig. 3. A common upper electrode 3c co-operates with a series of separate lower electrodes 2a-2i. These are shielded from each other by an earthed screen 6. The upper electrode may be combshaped as shown or it may be a plain straight plate or wire. The changes in capacity may be derived from characters marked on the card in dielectric ink instead of from perforations.

Title: Chlorine recovery
IPC: C01B7/00
Filed: 1958-06-05
Abstract: <PICT:0844115/III/1> In the recovery of chlorine from a stream of hydrogen chloride which contains free chlorine, the stream is contacted with an aqueous hydrochloric acid solution of at least azeotropic concentration, and chlorine is then separated from the gaseous effluent, preferably by cooling to below 0 DEG C., thereby recovering the chlorine as gas, and the aqueous hydrochloric acid thus formed may be employed in the contacting step, which is preferably carried out between 25 DEG C. and 50 DEG C.  In an example, a vapour stream of hydrogen chloride contaminated with chlorine and carbon tetrachloride is fed into scrubbing zone 3 via line 2, where it is scrubbed with aqueous hydrochloric acid of at least azeotropic concentration introduced via line 5.  This zone is maintained between 40 DEG C. and 50 DEG C.  The acid solution is in part recycled via line 8.  The effluent gas enters cooler 10, maintained between 0 DEG C. and -20 DEG C., preferably at -15 DEG C., whence chlorine, free of water, hydrogen chloride, and carbon tetrachloride is separated in 12.  The aqueous hydrochloric acid may be returned to zone 3.

Title: Process for producing synthetic anhydrite
IPC: C04B11/26
Filed: 1958-06-06
Abstract: Synthetic anhydrite is obtained by grinding fluorspar so that not more than 1% remains on a 170 mesh screen (A.S.T.M. Fine Series Mesh), and reacting it with its molar equivalent of concentrated sulphuric acid at 150 DEG  to 200 DEG C., the hydrogen fluoride obtained being passed into water to form hydrofluoric acid, and activating the anhydrite by adding to it material that gives it the property of setting when water is added to it (e.g. an alkali metal sulphate, lime or portland cement).  The fluorspar and sulphuric acid may be continuously mixed in one chamber, where a part of the hydrogen fluoride is removed, and the reaction mixture continuously conveyed to a second chamber gas-sealed from the first chamber, where the remainder of the hydrogen fluoride is removed.  The anhydrite obtained may be mixed with 3% of slaked lime or potassium sulphate. An example is given.

Patent GB-380821-A (GB)
Title: Improvements in or relating to the surface treatment of plasters and cements
IPC: C04B41/70
Filed: 1931-06-23
Abstract: Surfaces of plaster or cement are water-proofed by treatment with a water soluble salt of a higher fatty acid, such as sodium or preferably potassium oleate, stearate or palmitate.  If soluble calcium compounds are absent, the surface may be impregnated with e.g. lime water before impregnation with the salt.  The salt may be applied by brushing, wiping or spraying in aqueous solution or in the form of "soluble soap," or in emulsions with trichlorethylene, alcohol, and water.  Wetting agents such as naphthalene sulphonic acids and turkey red oil may be used with the soap to assist distribution.  The surface may be pretreated with a solution of alkaline silicate, or the silicate may be applied at the same time as the soap, to give a hard surface which may be polished.  It is advantageous to mix up to 10 per cent of portland cement or lime with plasters in general when they are to be water-proofed by the present invention.  White cements, plasters of the accelerated anhydrite type are particularly suitable for treatment.  In an example a 5 per cent aqueous solution of potassium oleate is sprayed upon a plaster obtained as described in Specification 317,672, [Class 22, Cements &c.].  The surface may then be polished but still remains waterproof. Specifications 236,695, 317,672, 337,926, [all in Class 22, Cements &c.], and 374,455 also are referred to.

Filed: 1974-04-26
Abstract: 1467966 Automatic control of seed planters DICKEY-JOHN CORP 26 April 1974 [18 June 1973] 18381/74 Heading AID [Also in Division G3] In order to keep constant the number of seeds per unit area sown by a planter comprising a seed dispenser 13 fed from a hopper 11, the number of seeds planted is counted by a sensor 14 and the ground speed of the planter is measured by a sensor 23, corresponding signals being fed to an electronic circuit which adjusts the speed of motor 32 driving the seed dispenser if the seed density' is not equal to the value set on a selector 25. As shown the two sensors are a photoelectric sensor and a wheel and produce pulse trains which are fed to respective inputs of an up-down counter 22, the distance pulses being fed via a divider 26 which is set by switches 25 to the desired planting density. The output of the counter 22 is converted to an analogue signal and used to control a servo valve 29 in circuit with the motor 32. The latter is a hydraulic motor supplied from a pump driven by tractor 10. When the tractor is stopped, a circuit 27 detects the absence of distance pulses and opens a bypass valve 31 to prevent creeping of the dispenser motor. If the distance pulse rate exceeds the planting pulse rate sufficiently to return the counter 22 to zero, a "clear" pulse is derived from the counter via an inverter (64, Fig. 3 not shown) and clears the counter to prevent the next down pulse producing a full count and closing the valve 29.
