Title: Improvements in or relating to liquid level regulators, more especially for steam boilers
IPC: F22D5/06
Filed: 1931-11-17
Abstract: 393,984. Feedwater regulators for steam boilers. BRITISH ARCA REGULATORS, Ltd., HENDERSON, W., and LINDSAY, T., Windsor House, Victoria Street, London. Nov. 17, 1931, No. 31899. [Class 123 (ii).] In apparatus for regulating the level of liquids, for example in steam boilers, an overflow pipe b<2> from the steam space of a boiler a leads through a condenser bl to a pipe b containing a constant head of water. A chambered block d pivoted at e has a short arm f on one side, and a tubular arm g containing mercury on the other communicating by a pipe c with the water space in the boiler. The mercury assumes a position balancing the constant head of water in the pipe b and static head of the water in the boiler. The short arm f is connected to an arm j carrying a checking member j<2> pressed towards a discharge aperture k by a spring j<1>. Thus, on decrease of the water level in the boiler the mercury will pass along the tube g, decreasing the pressure of the spring on the arm j and drawing the checking member away from the discharge aperture k which permits a servomotor l to pull a cable m which opens a valve o to admit steam to a boiler feed pump. The spring q, by variably assisting in supporting the screw i, prevents hunting of the mechanism as described in Specification 277,088, [Class 51 (i), Furnaces and kilns, Combustion apparatus of]. Specification 116,074*, [Class 69 (ii), Hydraulic presses &c.], also is referred to.

Title: Respiration belt
IPC: A63B23/18
Filed: 1926-12-17
Abstract: 270,596. K÷nig, O. Dec. 17, 1926. Respiration, appliances for promoting.-An appliance for use in respiration exercises, particularly by asthmatic, tuberculous, and other patients, comprises a belt or belts adapted to be passed around the chest and secured in front by a buckle c which yields resiliently to normal respiratory movements of the chest but is locked against subsequent inhalation if exhalation is incomplete. The buckle c comprises a rectangular or circular casing, a plate g slidable in the casing and resiliently connected with it by spiral springs or rubber strips h, and a cover (not shown) carrying a resilient pawl f. The plate g has secured to it a member n of inverted L section having oblique slots o in its upper edge. The plate g and the casing of the buckle c are connected respectively to opposite ends of the belt by straps such as i engaging eyes such as m. During inhalation the plate g slides in the casing against the action of the resilient strips h ; the pawl at the same time is pressed beneath the slots o and rises, by reason of its resilient mounting, beyond them. If exhalation is complete the pawl f is drawn back over the slots o and returns to initial position. Incomplete exhalation, however, allows the pawl f to engage one of the slots and thus prevents expansion of the buckle until exhalation has been completed.

Title: Improvements in or relating to data processing apparatus
Inventor: LEWIS CHARLES HENRY
IPC: G06F7/38
Filed: 1958-10-09
Abstract: 873,936. Digital electric calculating-apparatus. GAS COUNCIL. Jan. 8, 1960 [Oct. 9, 1958], No. 32281/58. Class 106 (1). The average value of a physical variable is calculated under each of a number of different conditions by means of apparatus comprising means arranged to sample in cyclic sequence the values of the variable in each of the different conditions and to apply the successive sampled values for each particular condition in digital form to a corresponding calculating means providing an indication of the number of samples applied thereto and their sum, or giving a direct indication of the average value of the variable under that condition. The variable may be temperature whose average value is to be found at each of a number of different locations. A code disc 1 coupled to a pen recorder feeds a binary-coded output signal representing the values of the variable under the different conditions in cyclic sequence to a sampler 3 comprising a number of gas-filled or cold-cathode trigger tubes of which selected ones are primed by the output of disc 1. Each trigger tube has a relay in its anode circuit having contacts arranged to convert the binary input to a decimal output on units, tens and hundreds conductors 4, 5, 6. A trigger pulse applied to sampler 3 fires the primed tubes and selects the appropriate output conductor in each of groups 4, 5, 6, and the delayed trigger pulse triggers one-shot pulse generator 8 to energize the selected conductors. Three - decade counter 9 is set to the value sampled, and the trigger pulse after a further delay then operates switch unit 10 to cut off the supply to sampler 3 whereby the relays are deenergized ready for the next sample. The energizing pulse from generator 8 is also delayed and fed to pulse generator 13 which triggers pulse generator 14 whose output train recycles counter 9 back to zero. Detector 15 stops generator 14 when each decade tube of counter 9 registers zero. The output of generator 14 is fed through selector 17 to the counter 16 corresponding to the condition appertaining to the sample. The inhibit pulse from detector 15 also steps selector 17 to the next position and registers a count in the counter 18 corresponding to the counter 16 in which the last sample was stored, so that counters 16 register the sum of the sampled values under the respective conditions and counters 18 register the number of samples taken in each of the conditions. Counters 16, 18 may be associated with computing means giving a direct indication of the average values.

Title: Improvements relating to the Automatic Control of Rolling Mills
Inventor: PECK PHILLIP ELWORTHY
IPC: B21B37/46
Filed: 1965-07-29
Abstract: 1,154,035. Automatic control of rolling mills. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 10, 1966 [July 29, 1965], No.32480/65. Heading G3R. In a system for automatically controlling the thickness of a batch of strip material being rolled in a cold rolling mill, automatic screw-down adjustments are recorded while the first strip is accelerated slowly through the mill and the recording utilized to assist screw-down adjustment when the remaining strips are accelerated at a normal rate through the mill. As shown, cold strip S passes through stands S 1 -S 3 , and interstand tensions are stabilized by detectors TR 1 , TR 3  automatically controlling the speeds of motors MR 1 , MR 3  driving stands S 1 , S 3 . The thickness of strip leaving the mill is maintained constant by a gauge GSH which automatically controls the tension stabilized by detector TR 3  and, through a limit gate TLG, the setting of a screw-down motor SD1 for stand S 1 . The first of a number of strips is accelerated slowly up to speed by operation of a rheostat RH controlling the speed of all driving motors, and a magnetic recording drum MD rotated with rheostat RH records screw-down settings corresponding to different speeds, the tension control being reduced to a minimum for this strip. Then when, subsequently, similar strips are being rolled, the mill is accelerated more rapidly by operation of rheostat RH and the recorder controls screw-down motor SD1 to reduce the duty on the automatic thickness control which then acts as a fine control.

Title: Improvements in bumpers or collision guards for vehicles
IPC: B60R19/28
Filed: 1928-11-09
Abstract: 324,434. Woodhead, G. A. Nov. 9, 1928. Collision guards or bumpers for vehicles are made from a single bar with integral supporting arms or brackets which are formed either by reducing the width of the bar at one or more places and bending these portions backwards behind the bar and/or by slitting the bar so as to leave integral portions which are free to be bent out of the plane of the bar so as to constitute supporting arms having a certain degree of resilience. In the construction shown in Figs. 3 and 4, the reduced ends b of the bar a are bent rearwardly to form integral supporting arms, while the main or central portion a is reduced in weight either by punching out a part a<1> or by reducing the thickness of the bar at this part. In various other constructions two or more portions b. formed by slitting the bar at a<1> may be displaced rearwardly with both ends remaining attached to the bar as shown in Fig. 5, or by welding the outer ends of the strips b to the rearwardly bent ends c of the bar a as shown in Fig. 7, or by dividing the strips b as shown in Fig. 9. Rear half-bumpers may also be constructed with supporting arms b formed by reducing and bending back the bar a, or by punching out strips b, or by both methods as shown in Fig. 18. Several other modifications are described, while the initial cross-section of the bar may also be varied.

Abstract: Organic compounds containing at least one terminal gem dinitro grouping of the formula <FORM:1077065/C2/1> wherein M is hydrogen or a metal, are fluorinated by reaction with fluorine in the presence of a moderator which is less reactive with fluorine than the compound being fluorinated. The terminal grouping is converted to <FORM:1077065/C2/2> Suitable moderators are water, alkanols, alkylene glycols, alkanes, haloalkanes, aromatic hydrocarbons, chlorinated aromatic hydrocarbons, ketones, ethers, and alkyl substituted amides; many suitable organic moderators are specified.  The organic radical attached to the terminal gem dinitro grouping may be a substituted or unsubstituted alkyl, cycloalkyl, aryl, or heterocyclic radical or a radical interrupted by a hetero atom, e.g. S, N, or O, or by an ester grouping.  When the organic compound treated contains two gem dinitro groups, the link between these groups may be a substituted or unsubstituted alkylene or arylene radical which may be interrupted by nitrogen, nitraza, sulphur, or oxygen.  The dinitro compound may be dissolved or suspended in the moderator; fluorine, diluted if desired, with helium or nitrogen, is passed through the liquid.  Many fluoro compounds which may be formed are specified and examples are given of the preparation of the following: 1-fluoro-1,1 dinitroethanol, phenyl dinitro fluoromethane, 1 - fluoro - 1,1 - dinitroethane, 1,3 - difluoro-1,1,3,3 - tetranitro - propane, bis - (3 - fluoro-3,3 - dinitropropyl) maleate, N,N1 - bis - (2-fluoro - 2,2 - dinitroethyl) hydrazine, di - (3-fluoro - 3,3 - dinitropropyl) ether, -N - nitro-2,21 - difluoro - 2,2,21,21 - tetranitrodiethylamine, 1 - fluoro - 1,1 - dinitro - 3,3 - dichloropropane, 1 - fluoro - 1,1,3,3 - tetranitrobutane, 4 - fluoro-2,2,4,4 - tetranitrobutylacetate, 3,31 - difluoro -3,3,31,31 - tetranitro - 2,21 - dichlorodipropylamine, 1 - fluoro - 1,1 - dinitro - 4 - nitraza heptane, 2 - fluoro - 2,2 - dinitroethyl benzoate. Moderators used in the examples are water, chloroform, ethylene glycol, benzene, dimethyl acetamide, hexane, 1-propanol, diethyl ether, nonane, dimethyl ketone, dimethyl formamide. The fluoro dinitro compounds are useful as explosives, for example in a missile as described in United States Specification 2,470,162, or as oxidizers for liquid rocket fuels such as hydrazine.  In Example 5, bis-(3,3-dinitropropyl) maleate is prepared by esterification of the alcohol with the acid, and is subsequently converted to its barium salt by reaction with barium hydroxide.  In Example 14, 2,2-dinitroethyl benzoate is prepared by esterification of the acid with the alcohol.
