Title: Improvements in or connected with means for recording user of apparatus
IPC: E05B35/00
Filed: 1924-10-02
Abstract: 245,487. Fullarton, H. N., and Brown, M. S. Oct. 2, 1924. Recording particular operations. - In means for recording the use of an apparatus a locking device is provided which is released by an operator's key, and after the setting for use has been completed is operated to prevent further setting until the lock device is again released by the same or a different key. During the setting operation an identification record of the key used is effected, and after the setting operation is completed the key is free to be removed. The means may be associated with a fluid or other meter, telephone, &c. As shown in Figs. 1, 2 applied to a gas meter for controlling the valve mechanism the operating spindle A of the valve has a pinion 2 gearing with a pinion 7 freely mounted on a shaft 3. Integral with the pinion 7 is a notched locking disc C and a cam disc 9 the parts being connected by a pin 10 to which is secured one end of a spring 8. The spring 8 is attached at its other end to the shaft 3 and on the said shaft is fixed a second locking disc B, a cam disc 4, a ratchet wheel 5, and a setting hand wheel 6. In the normal position the notches in the locking discs are engaged by a bolt D adapted to be released by the action of any one of a series of keys F. Each of the keys acts upon a corresponding set of levers E in such a manner as to turn the appropriate lever further than the rest so as to present a type 13 to an inking-ribbon and record-strip. The ribbon and strip are fed by means of pawls 19 mounted on a rod G adapted to be reciprocated by means of an eccentric 18 on the shaft 3. The impression is effected by a hammer 20 retracted by a pawl 21 having faces 23, 25 bearing on the cam discs 9, 4 respectively. A pin 12 on the bolt D is adapted to engage recesses in the levers E to hold them in set position. In operation the key releases the bolt D whereupon the hand wheel 6 is operated to rotate the notched disc B so as to retain the bolt in the withdrawn position and to apply torque to the spring 8. During this setting the disc C is held stationary until the pawl 21 is rocked to free the face 23 from the cam disc 9 whereupon the spring effects the rotation of the disc C and thereby actuates the spindle A, the disc C being arrested in the normal position whereupon the bolt is returned to locking position.

Abstract: 1,117,736. Nuclear power plant. BROWN BOVERI/KRUPP REAKTORBAU G.m.b.H. 25 May, 1966, No. 23475/66. Heading G6C. A nuclear power plant comprises a heterogeneous nuclear reactor having a core with two separate cooling channels, at least one of which may consist of groups of channel elements connected in parallel, the first cooling channel carrying a coolant introduced in the liquid state and the second cooling channel carrying a gaseous coolant, wherein the liquid coolant is evaporated in the reactor core and the vapour mixed with the gaseous coolant leaving the second channel, the gas-vapour mixture led to a heat engine, e.g. a turbine, and the gasvapour mixture leaving the heat engine separated into its components which are subsequently returned to their respective cooling channels. In one example, the reactor core 2 is surrounded by a reflector 3, an inner vessel 5 forming the first cooling channel and an annular channel 4 between the reflector 3 and the vessel 5 forming the second cooling channel. The channel 4 and the inner vessel 5 both discharge into a mixing chamber 6 in which gas from the channel 4 and saturated steam from the vessel 5 are intimately mixed and the steam superheated. The gassteam mixture issues from the chamber 6 through a pipe 7 and enters a turbine 8 from where it is led to a condenser 10. The gas leaving the condenser 10 still contains a volume of steam corresponding to the saturation steam pressure and is pumped by a pump 11 into a supplementary condenser 12 where more water is condensed. The water from the condensers 10, 12 is forced into a feed-water tank 14 by feed pumps 13, 15 and the return of the cooling water from the tank 14 to the inner vessel 5 is effected by a feed pump 19. Gas from the supplementary condenser 12 is delivered by a gas pump 16 into a gas cleaner 17 before being returned to the channel 4. Water precipitated in the gas cleaner 17 flows through a branch pipe 18 into the tank 14.

Filed: 1931-08-28
Abstract: A coating-composition for application as a top coat to coated textile or other flexible fabrics such as artificial leather consists of an asphalt, a drying-oil-modified polyhydric alcohol-polybasic acid resin and a solvent, with or without driers and pigments, the composition being particularly applicable to fabrics coated with uncured rubber.  An intermediate coat of oil varnish is preferably applied and the fabric may be baked at a vulcanizing temperature. The coating compositions may consist of petroleum asphalt, an artificial resin formed from glycerol or glycol, phthalic anhydride or succinic acid, linseed and chinawood or perilla oil acids or perilla oil, a solvent, such as naphtha or turpentine, and a cobalt or lead-manganese drier.  Varnishes suitable for the intermediate coating contain carbon black, bodied linseed or chinawood oil, or both, a drier, asphalt and turpentine substitute.  The coating is preferably applied to the unvulcanized rubber coating which is baked for such a time and at such a temperature as to dry the varnish without completely vulcanizing the rubber.  After this, the coat of asphalt varnish is applied and baked so as to complete the vulcanization and dry the asphalt varnish.  When only a single coat of asphalt varnish is used, this is applied preferably to the unvulcanized rubber coating and treated as described above.  The invention may be applied to fabrics coated with nitrocellulose or linseed oil.

Abstract: 1,043,456. X-ray tubes. MACHLETT LABORATORIES Inc. June 11, 1964 [June 14, 1963], No. 24312/64. Heading H1D. An X-ray tube for use in stereo-fluoroscopy includes within an evacuated envelope a rotatable target, and means for directing electrons alternately on to two spaced spots on the target, the resulting X-rays from the two spots passing to a common irradiation zone. Two cathodes 12, 12a are mounted in the same envelope 10 opposite a tungsten anode disc 11 rotatable on shaft 14 by an inductor 17 disposed outside the envelope. The cathode support tubes, 19, 19a are offset, Fig. 2, such that X- rays produced at the corresponding focal points 28, 28a-which are spaced by the interpupillary distance-are emitted through the window 29. The apertured blocks 21, 21a act as control electrodes, normally biasing the treated cathodes 24, 24a to cut-off, but being alternately pulsed to permit the impingement of an electron beam alternately on the corresponding focal points 28, 28a. The control electrodes may alternatively be parallel wire or mesh grids, and each cathode may have two filaments (Fig. 6, not shown). In an alternative embodiment (Fig. 3, not shown) the electron beam from a single cathode is deflected repetitively from one focal point to the other, by deflection electrodes. The X-ray images corresponding to the two focal points are received upon the screen of an image intensifier, and are viewed through a binocular viewer provided with a shutter which is operated synchronously with the operation of the two cathodes, or the deflection of the beam from the single cathode. A pulsing circuit for the cathodes is described (Fig. 7, not shown).
