Patent GB-1165248-A (GB)
Title: Lock Actuators
Inventor: THOMAS GORDON FREDERICK FRANK
IPC: B60T11/04
Filed: 1967-06-19
Abstract: 1,165,248. Brake actuators. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. 22 May, 1968 [19 June, 1967], No. 28227/67. Headings F2E and F2F. In a fluid pressure operated brake actuator having a fluid pressure operated locking means to provide a parking brake; jamming of the locking means due to shrinkage of the brake drum after application of the parking brake is prevented by including in the actuator a resiliently collapsible means to limit the maximum brake application which can be locked into a value below that at which jamming would occur. As shown in Fig. 1, the brake operating member 2 comprises two telescopically slidable parts 12, 17 and the resiliently collapsible means comprises a stack of belleville washers 22. During normal application of the brakes, the loads are not sufficient to compress the washers and the member 2 therefore acts as a rigid rod. However, when a brake application is locked in when the brake drums are hot, subsequent contraction of the brake drums may impose loads on the member 2 greater than those obtainable in normal braking and the belleville washers 22 will then yield to prevent the load on member 2 rising to a level at which the locking means 3 would jam. In another arrangement, Fig. 3 (not shown), belleville washers (36) are included between the housing (1) of the brake actuator and a mounting means therefor. Helical springs or rubber springs may be used instead of belleville washers.

Title: Apparatus for winding of sewing thread upon bobbins
IPC: D05B59/00
Filed: 1971-06-16
Abstract: 1321932 Securing start of winding E L JOHANSSON 16 June 1971 [16 June 1970] 28257/71 Heading D1J A machine for winding sewing-machine bobbins 25 (Fig. 1) comprises a rotor 11, driven via belt 21 from motor 19, with a central stem 23 on which the bobbin 25 is mounted, means for attaching the thread end to the rotor (in this embodiment a spring clip 65) at a greater radius than that of the bobbin, and a catching member 89 movable into the path of a thread extending between clip 65 and the bobbin as the rotor rotates, so as to draw the thread end out of the clip. In operation, thread is stretched between tensioner 33 and clip 65 in the Fig. 3 position, where the rotor automatically stops due to a pin 55 thereon engaging a portion of a starting lever 37. Lever 37 is depressed, starting the motor and causing a pressing arm 51 to engage the surface of the thread, which commences winding on the bobbin. Initially catching member 89 is held out of the path of the rotating thread end by a projection on the arm 51, which, as the winding grows, releases member 89 to free the thread end from clip 65. Further growth of the package moves arm 51 to a point where lever 37 is allowed to spring up once more, and package rotation is halted. The wound bobbin is removed manually, the thread linking it to the supply being then again tucked under clip 65 and cut on a knife edge 77. A new bobbin is placed on the stem, and the operation re-started.

Patent GB-832060-A (GB)
Title: Process and apparatus for purifying hydrogen
IPC: C01B3/52
Filed: 1958-09-05
Abstract: <PICT:0832060/III/1> Hydrogen is freed from gaseous impurities including carbon monoxide and nitrogen by washing at superatmospheric pressure and a temperature of less than - 180 DEG  C. with a liquid having a vapour pressure of less than 1/500 th of that of nitrogen at said temperature, the liquid being recycled to the washing step after desorption impurities.  The washing liquid preferably comprises one or more C2 and/or C3 aliphatic hydrocarbons, e.g. ethane, ethylene, propane, or propylene.  Proportions, washing temperatures, and rates of flow are specified.  The impure hydrogen may be subjected to a preliminary treatment to remove most of the water and carbon dioxide, it may be supplied for use in the present invention at a pressure of below 25 p.s.i.g., preferably 300-400 p.s.i.g., and may be cooled to the washing temperature by heat exchange with the product hydrogen and desorbed gaseous impurities, the remaining water and carbon dioxide thereby being removed.  After the washing step, partial desorption of impurities may be effected by warming the wash liquid, e.g. from - 185 DEG  to - 120 DEG  C., and reducing the pressure, e.g. from 300 p.s.i.g. to 6 p.s.i.g.  Further removal of impurities may be effected by passage of a portion of the hydrogen product through the partially purified wash liquid.  As shown, impure hydrogen passes from a heat-exchanger 12 via line 16 to a wash tower 17 most of the washed hydrogen passing back through the heat-exchanger via line 20, the remainder being passed via line 20a to separator 29.  Separated gaseous impurities together with hydrogen pass from the separator to the heat exchanger via line 30, while regenerated washing liquid passes via line 34 through a pump 33, and heat exchangers 24-25 and 26a-27a, to washing tower 17.  The washing liquid passes from the washing tower to the separator via line 21, heatexchangers 24-25 and 26-27, and expansion valve 28.  Recooling of the washing liquid may be effected in heat-exchanger 26a-27a with the washed hydrogen after expansion (Fig. 2, not shown), or with liquid nitrogen (Fig. 3, not shown), which may be recycled after recooling (Fig. 4, not shown).  A portion of the impure hydrogen may be cooled before passing to heatexchanger 12 by heat-exchange with the impurity-containing wash liquid (Figs. 2 and 3).

Filed: 1922-10-21
Abstract: 207,347. Ross, T. W., and Metropolitan- Vickers Electrical Co., Ltd. Oct. 21, 1922. Protective arrangements. - In protective systems employing relays which control the operation of automatic circuit breakers, the relays are provided with a lock-out or retaining coil which prevents the action of the relay when a current greater than the circuit breaker can safely handle is flowing in the circuit to be protected. The induction relay shown in Fig. 1, has a main operating coil 7 mounted on the core 1 and supplied from the primary 8 of a saturable transformer 9 the primary 10 of which may be connected at 12 to the primary of a series current transformer in the circuit to be protected. Shaded poles having a coil 4 are provided on the arc 1, this coil being in series with the energizing coils 5, 6 for the magnetizable core 3. In series with the winding 10 supplied from the main circuit is an opposing coil 11 wound on the core 1 and so arranged that if the main current exceeds the capacity of the. circuit breaker controlled by the relay the action of the coil 11 predominates over that of the coil 7, the current in which is limited by the saturation of the transformer 8, thereby reducing the torque on the disc 3 to a value insufficient to operate the relay disc. In order to prevent the current in the coil 11 being increased with very heavy overloads to an extent which might cause operation of the relay it may also be supplied through a secondary saturable transformer 13 supplied from the main circuit as shown in Fig. 2.

Title: Preparation of amino alcohol esters of disubstituted malonic acids
Filed: 1948-11-05
Abstract: Dialkylmalonic acid alkyl dialkylaminoalkyl esters are prepared by treatment of a dialkylmalonic acid monoalkyl ester with a chloroalkyldialkylamine.  The products have the formula <FORM:0656864/IV (b)/1> where R1 to R5 represent alkyl which may be substituted and R6 is alkylene.  In the examples: (1) di-n-butylcyanacetic acid ethyl ester is hydrolysed to di-n-butylmalonic acid ethyl ester amide, which is treated with acid and sodium nitrite to give di-n-butylmalonic acid monoethyl ester, further reaction of which with b -chloroethyldiethylamine in presence of potassium ethoxide affords di-n-butylmalonic acid ethyl diethylaminoethyl ester; (2) diethylmalonic acid monoethyl ester is similarly treated with b -chloroethyldiethylamine to give the ethyl diethylaminoethyl diester.  It is stated that other substituted malonic acid alkyl monoesters and alkyl dialkylaminoalkyl diesters may be prepared where R2 and R3 are di-n-propyl-, di-isobutyl-, di-n-amyl-, di-isoamyl-, and where R2 is isopropyl and R3 either ethyl or butyl.  The Specification as open to inspection under Sect. 91 comprises the statement that the amine reactant may be the halide or sulphonate of an amino alcohol, which may be piperidine ethanol; in addition the groups R2 and R3 may be aralkyl or aryl, e.g. the compound dibenzylmalonic acid monoethyl ester may be prepared and used in the reaction.  This subject-matter does not appear in the Specification as accepted.

[Also in Group XL (c)] A circuit for producing an alternating current of specified frequency, the amplitude of which is a function of the difference in amplitude between two D.C. inputs consists of two resistances directly connecting the input to the output, the output being shunted by a pair of diodes to which A.C. is fed through either a diode or a triode. In one embodiment, Fig. 2, the D.C. outputs of a discriminator 35, 36 appear across resistors 13, 14 which have a common negative connection. The inputs are connected by the resistors 16, 19 to the A.C. output (the control grids of a push-pull amplifier 37, 38), which is shunted by the diodes 24, 26. The conduction of diodes 24, 26 is controlled by a diode 25 having its anode connected to an A.C. modulatong source. All three diodes have a common cathode connection via resistor 22 to the mid. point of the input circuit. In a modification, Fig. 3 (not shown), the conduction of the diodes 24, 26 is controlled by a triode, the grid/cathode path of which connects the common cathode of diodes 24, 26 to the input, the triode being anode modulated. In a second modification, Fig. 4 (not shown), the triple diode of Fig. 2 is effectively replaced by a double triode using the two grids as two of the diode anodes and strapping the anodes together to form the third diode anode. In a third modification, Fig. 5 (not shown), the modulating diode is replaced by a grid-modulated triode. In a fourth modification, Fig. 6, one D.C. input 50 is compared with a reference source 65, the inputs again being connected by resistors 16, 19 to the output which is shunted by a pair of diodes formed by the cathodes and grids of a double triode 66, 67. The anodes of the triodes are strapped and connected via a diode 63 and resistor 64 to the common input terminal. The modulation is applied to the anodes via a diode 61.
