Abstract: 297,361. British Tabulating Machine Co., Ltd., (Assignees of Decker, S. K., Johnson, G. A., Davis, J. W., and Junor, J. B.). Sept. 19, 1927, [Convention date]. Coupling machines for simultaneous operation; keyboard operators. - In a machine for preparing simultaneously a punched ledger card 5 for statistical purposes and a printed card 3 for a customer of a gas or other company, a Burroughs adding or other machine prints the card 3 and a punching- machine perforates the card 5. The machines are electrically connected so that both printing and punching are controlled from the adding machine keys. The cards are inserted in the respective machines and classification data to be punched on the card 5 and not printed are set up on the first two rows of adding-machine keys and a manual switch is operated. The error key of adding machine is then operated to clear the machine. The readings to be printed on card 3 and punched on card 5 are then set up and the operating key of the adding machine is depressed to effect the printing and to set up the punch selectors. Each key of the adding or other machine is provided with contacts 54 which are closed on depression of a key. A row of contacts 81 for zero punching are normally closed and are opened on depression of a numeral key in the same column or by other mechanism. A contact 74, rotated from the machine, bridges contacts 68, 73 on each rotation. A bar 62 is depressed to close switch 65 to effect printing. The punching machine has a plurality of rows of punches with punch-selecting mechanism on a carriage stepped successively over each row of punches and means for effecting punching when all the punches are selected. Brushes 63, 51 ou the punch-selecting carriage travel over a stationary commutator bar 41, 45. The parts are wired up as shown in Fig. 3. After actuating the keys of columns 1 and 2 of the adding or other machine a switch 53 is depressed. The circuit for the first column is source G, 103, 73, 68, 104, switch 53, 105, 51, contact 47 to the key contacts of column 1 and then through the depressed key contact through the corresponding punch-selecting solenoid 102. The punch-selecting carriage moves one step, the brush 63 engages contact 42, and a circuit is completed independently of switches 53, 62 from source G through 103, 73, 68, 106. 63, 42 to the contacts of row 2, and thence through the depressed key contacts and the corresponding solenoid. The error key 111 is depressed and the machine cleared. A complete reading is then set up and bar 62 is depressed to complete a circuit as for column 1 and afterwards for column 2 for the remaining columns. The carriage stops when a contact 49 is reached. The second set up is then made in a similar way and finally a contact 70 actuates the carriage-return solenoid.

Title: Improvements in or relating to methods of making peroxides of organic acids
IPC: C07C409/34
Filed: 1926-10-26
Abstract: 271,725. McKee, R. H. Oct. 26, 1926. Peroxides of organic acids.-In the manufacture of peroxides of organic acids by the action of a peroxide solution on an organic acid chloride, the hydrogen ion concentration of the reaction mixture is maintained near the neutral point by the use of a buffer compound. Generally, the hydrogen ion concentration is maintained at or about pH 7.5, but benzoyl peroxide is preferably made at or about a concentration pH 8.5, and some other peroxides may be made at or about a concentration pH 6. The preferred buffer compound is disodium phosphate, but other compounds such as sodium bicarbonate or borax may be used. The process may be carried out by adding disodium phosphate to a dilute solution of hydrogen peroxide in such an amount that in the subsequent reaction with the acid chloride, for example phthalyl chloride, about 90 per cent of the disodium phosphate will be converted into monosodium phosphate. The phthalyl chloride is then stirred or sprayed into the mixture, the temperature being kept at 40-65‹ F., whereafter the separated peroxide is washed and dried. For fumaryl peroxide a reaction temperature of 30- 40‹ F. is used. The process may be modified by using less disodium phosphate and, when about half of the acid chloride has been added, adding caustic soda or soda ash in amount sufficient to reconvert into disodium phosphate the monosodium phosphate formed in the reaction. Alternatively. the caustic soda or soda ash may be added slowly during the reaction, in which event the amount of the buffer compound may be further reduced.

Abstract: 633,199. Splitting and gutting fish. ARENCO AKTIEBOLAG. Oct. 10, 1947, No. 27296. Convention date, Oct. 17, 1946. [Class 28(ii)] In a fish-dressing machine the tail pulling jaws 17 are so disposed about their pivots 8 that they are self-locking and any retardation of the fish increases the grip. The jaws are held open until their lever rollers 10 clear fixed cam bars 11 during the conveying pull, whereby a spring 12 is then able to urge the jaws 17 towards each other to grip the tail of a fish. A fish placed in a trough 3 is gripped by its tail grippers 17 on endless conveyer chains 1 and pulled from yielding guide plates 16 through a channel 6 and through further guide 18 to a rotary splitting wheel 4. The tail end of the fish is bent down when the jaws 17 pass the front end of the trough. by a cam roller 24, Fig. 4, engaging a fixed guide bar 26 whereby the jaws 17 rock down about their pivots 22, Fig. 3, of the jaw carriage 2. The fish tail continues to be held down while being split by the wheel 4, until the gills are removed by a gilling wheel 5 and until the guts are removed by a brush. 7, thereafter the jaws are released so that springs 35 may restore them to normal position. The jaws are opened by the roller 10 engaging the fixed guide bar 33. The trough 3 has yielding sides 16 to allow the fish to be pulled out. The jaws 17 are held open by roller 12 engaging fixed cam plates 11 until gripping position is reached, when a spring 12 closes them. The jaws have inter-engaging toothed segment 20 for uniform closing, and are designed so that the pull on the fish tail causes them to grip and close more firmly on the tail.
