Title: Device for counting coins, tokens and similar disc-like articles
IPC: F41A7/08
Filed: 1930-02-17
Abstract: 346,101. Counters for coins. VOGT, C., 21, Luisenstrasse, Berlin. Feb. 17, 1930, No. 5308. [Class 106 (i).] In coin-counting apparatus in which the coins are brought by driving rollers into engagement with a star-wheel, a coin stop is held in an inoperative position by a bar which is moved one step at each revolution of the star-wheel until a predetermined number of coins has passed, whereupon the bar allows the stop to move into such a position that the coin supply is interrupted. The coins leaving a shoot 1 are caused by rotating rollers 2 to actuate a star-wheel 3 connected to counting apparatus (not shown). At each revolution of the wheel 3, a pin 6 thereon engages a cam 8 having a pawl 10 which moves by one step a bar 12. The bar 12 is pulled to the left by a spring 44, a collar 15 enabling it to be set so that one of a number of graduations is adjacent to an index face 14. A locking pawl 21 contacts with the top of the bar 12. One of the arms of a U-shaped sliding member 34 bears on the bar 12, and when the bar has been displaced by the passage of the last coin in the batch for which the bar was set, this member passes through an opening 42 in the bar under the action of a spring 37 and closes the end of the shoot by a stop 31. To reset the device a lever 41 is rocked, the member 34 then being raised above its normal position until a projection 30 rocks a plate 24 pivoted at 23. A projection 29 on the plate then lowers the pawl 10 and a slot 25 therein rocks the locking pawl 21, the bar 12 thus being freed to return to its set position. The plate 24 is normally held by a spring 26 against a stop 27.

Title: Improvements in or relating to process and intermediates for preparing steroid compounds
IPC: C07J75/00
Filed: 1958-02-19
Abstract: The invention comprises 3a ,5b  and 3b ,5a  steroid compounds of the general formula <FORM:0873633/IV (b)/1> wherein R1 represents <FORM:0873633/IV (b)/2> X represents chlorine, bromine or fluorine and "#x" represents a p  bond in the a - or b -position, and a method for epimerizing an 11b -bromo compound having the following formula to the corresponding 11a -bromo compound <FORM:0873633/IV (b)/3> wherein R2 represents <FORM:0873633/IV (b)/4> or -O-acyl and "#x" has the above significance, by treating the said 11b -bromo compound with a strong inorganic or organic acid at a temperature in the range of about 15 DEG  to 40 DEG C., and the process may be extended by reducing the resulting 11a -bromo compound with an alkali metal borohydride or lithium aluminium hydride to form an 11a -bromo-3,12-diol having at the 17-position the R1 group defined above, reacting this compound with a strong inorganic base such as sodium or potassium hydroxide, to form the corresponding 11b ,12b -epoxide, reacting the epoxide with hydrobromic, hydrochloric or hydrofluoric acid to form compounds of the first general formula above.  The above processes may be modified in that the 11b -bromo reactant of the second general formula above is prepared by acylating a compound of the general formula <FORM:0873633/IV (b)/5> wherein R1 and "#x" have the above significance, to form the corresponding compound having acyloxy groups in the 3 and 17 or 20 positions, oxidising this compound, e.g. with chromic acid, to form the corresponding 12-one compound and in the case where the acyloxy groups are inert to bromine, brominating to introduce the 11b -bromine atom, and in the case where the acyloxy groups are reactive to bromine, hydrolysing the 12-one compound to the free diol, acylating to form acyloxy groups which are inert to bromine in the 3 and 17 or 20 positions and brominating to introduce the 11b -bromine atom.  Acyloxy groups reactive to bromine are hemisuccinoyloxy and hemiphthaloyloxy groups. Non-reactive acyloxy groups are aromatic acyloxy groups such as benzoyl and tolyloxy and lower alkanoyloxy groups such as acetyloxy, propionyloxy, and butyryloxy groups. Detailed examples are given.  Pregnane (and allopregnane)-3a ,12a ,20b -triol are prepared by reducing the 20-keto group of pregnane (and allopregnane)-3a ,12a -diol-20-one diacetate, e.g. with a bimetallic anhydride such as sodium borohydride or lithium aluminium hydride with hydrogen in the presence of a hydrogenation catalyst such as Raney nickel, to form pregnane (and allopregnane)-3a ,12a ,20b -trial 3,12-diacetate and hydrolysing these compounds in alkaline solution.  Testane-3a ,12a ,17b -triol is prepared by oxidising pregnane-3a ,12a -diol-20-one diacetate with perbenzoic acid to form testane-,3a ,12a ,17b -triol 3,12-diacetate and then hydrolysing this compound.  Reference has been directed by the Comptroller to Specifications 779,987, 779,988 and 779,989.

Title: Improvements in electro pneumatic valves for compressed air brakes
IPC: B60T13/66
Filed: 1924-03-05
Abstract: 212,898. Compagnie GÚmÚrale d'ElectricitÚ. March 16, 1923, [Convention date]. Fluid-pressure.-In an electromagnetically controlled distributor valve for fluid pressure brakes, the brake cylinder pressure established is dependent upon the intensity of the current supplied to the coil of the valve. The valve may be combined with the usual automatic compressed air brake system. The intensity of the current and thus the braking pressure may be caused to vary according to the load and the speed of a vehicle to which the brake is applied, so as to avoid skidding of the wheels. The rod 16 forming the plunger of a solenoid curries a pair of pistons 6, 7, the area of the piston 7 being twice that of the piston 6 which controls ports 11, 10 leading respectively by connections 3, 4 to the auxiliary reservoir and the exhaust passage of the triple valve of an automatic pressure brake system. The brake cylinder is connected at 2. The coils of the valves for the several vehicles of a train are connected in series and normally with no currert flowing each valve is held by a spring 17 in the position shown in which the brake cylinder is open to exhaust through the triple valve and ports 10, 5, 15. The solenoids of the valves are so designed that the pull on the plunger 16 is independent of the stroke thereof and dependent only upon the current strength. When the solenoid is energized the rod 16 moves upwards so that the piston 6 closes the exhaust port 10 and uncovers the port 11 to admit air from the auxiliarv reservoir to the brake cylinder until the pressure therein acting upon the piston 7 is sufficient to overcome the electromagnet force corresponding to the strength of the current supplied, when the valve is returned to the lap position. By varying the current the braking pressure may thus be graduated upwards or downwards as desired. The brakes may at any time be applied also by reduction of the train-pipe pressure. To render the braking pressure dependent upon the load of a vehicle a resistance arranged in shunt to the solenoid of each valve is adapted to be varied by a lever 21 movable over a sector 19 and actuated by a piston 24 in a cylinder 25 connected to the brake cylinder. As soon as pressure is established in the brake cylinder the lever 21 is moved by the piston 24 until the rod contacts with a part 26 on an axle-box of the vehicle, the amount of this movement and thus the current passing through the solenoid being dependent upon the load. To render the braking pressure dependent upon the speed of the vehicle, the current may be supplied by a dynamo driven from the axle of the vehicle, in series with a battery of accumulators so that that part of the voltage which is due to the dynamo falls gradually to zero, thereby reducing the current strength.

Title: Improvements in distillation processes
IPC: C07C7/08
Filed: 1944-03-29
Abstract: <PICT:0580108/III/1> A liquid mixture is separated into two components by distillation in the presence of two entraining agents, one of which must form a constant boiling mixture of minimum boiling point with one of the components: this upward entrainer is fed to the side of the fractionating column, at least in part, at or below the level at which the mixture to be separated is introduced, while the other entrainer, which must not form constant boiling mixtures with either of the components or with the first entrainer, is fed to the column above this level, whereupon it flows downwards extracting the component which does not form a constant boiling mixture.  Aromatic hydrocarbons may be separated from non-aromatic hydrocarbons using acetone and cresylic acid as upward and downward entrainers respectively.  Alternatively, methanol may be used as upward entrainer, and phenol or aniline or their homologues, may be used as downward entrainer.  The mixture to be separated is fed to column 1 through line 3, the downward entrainer is supplied through line 4 and part of the upward entrainer is introduced through line 6 or 6a.  The bottom product from column 1, which comprises the downward entrainer and one of the components of the feed mixture, is pumped through line 7 into auxiliary column 8 in which this component is separated as a top product and withdrawn via condenser 10 and cooler 11; the separated entrainer is withdrawn from the base of column 8 and returned to column 1 via line 13 and heat exchanger 5.  The top product from column 1, which comprises a vapour mixture of the upward entrainer and the other component of the feed mixture, is condensed and the condensate is divided into two streams, one of which is returned to column 1 as reflux, while the other is sufficiently cooled in cooler 17 to allow it to stratify into two phases in separator 18.  The phase which is richer in the upward entrainer, is returned to column 1 through lines 19 and 6 or 6a. The other phase is distilled in auxiliary column 22, where it is separated into two fractions, one of which is the second component of the original mixture; this is withdrawn from the base through cooler 24.  The heads fraction is in the constant boiling mixture and this is condensed and added to the non-reflux part of the condensate from column 1.  The process may also be applied to the separation of saturated from unsaturated hydrocarbons; of the lower aliphatic alcohols from their mixtures with water; of esters and alcohols; and to the concentration of aqueous solutions of acetic or homologous acids.

Abstract: 1455900 Flash illumination control KONISHIROKU PHOTO INDUSTRY CO Ltd 8 Feb 1974 [9 Feb 1973 (2)] 05803/74 Heading G2A A reflex camera has means for detecting the amount of a pre-emitted light reflected from a subject to be photographed, and for using this to control the amount of light emitted by the main flash. Fig. 1 shows a camera in which the interchangeable lens 2 has a diaphragm-adjusting member 2b which can engage with a corresponding member 1a within the camera. When the shutter release is pressed, member 1a moves downwards to engage member 2b, so closing down the diaphragm to a pre-set value. Then switch 12 is closed, which energizes the pre-emitted light. The light reflected from the subject enters through lens 2 and is reflected up into the viewfinder path, passing through condenser lens 5. Part of the light is reflected from an inclined half-silvered mirror 6 set in lens 5 to a light-sensitive element 11 which matches the light with exposure conditions and controls the output of the main flash accordingly. The mirror 3 now pivots out of the light path, the shutter 10 in front of the film opens, and the main flash is energized. In the modification of Fig. 2 (not shown), the lightsensitive element 11 is positioned in front of the shutter, and retracted out of the light path when the mirror 3 swings up to the exposure position. In this case the movement of the mirror itself actuates the switch 12.
