A lace making apparatus comprises means for feeding a plurality of continuous strands, means for applying tip material to each strand, means to direct the strands to a severing station, means for engaging and positioning the strands on an anvil block, means adjacent the block for locating the tip material on the block and a cutter blade movable towards the block for severing the strands. Braids 30, 30<SP>1</SP> are fed from reels 20, 20<SP>1</SP> over grooved rods 21, 211 and co-operating driven drums 23, 23<SP>1</SP> to tipping mechanism 40, 40<SP>1</SP> where tipping material is wrapped round the braids then are guided over selected pulleys of a series of pairs of pulleys 47, 47<SP>1</SP> &c. or over one pair of pulleys adjustably positioned according to lace length then passes between a pair of solenoid operated arms of an aligning device 33 with slotted guide 30 to a severing device and a transfer dial for the gripping jaws 69 of a packaging machine. The dial 50 supports a braid clamp at diametral notches. Each clamp comprises two jaws centrally connected by a finger; spring urged together at the lower end. One jaw is pivotally mounted adjacent a notch on the dial 50. One clamp is opened by a pair of shoes exerting pressure on the lower ends of the jaws, the shoes being actuated by two plungers pivotally connected by linkage to the plunger of a solenoid 70<SP>1</SP> acting through one dial notch. One jaw of the other clamp abuts the disc and is opened by one shoe actuated by solenoid 70. The clamps are controlled as the disc rotates through 180 degrees by an arcuate guide 215 over the dial and by a pivoting guide surface 216 conducting the laces to the gripping jaws. A pulley 102 on rotatable arm 103 bears down upon the laces to take up any slack as the dial rotates. A solenoid operated cutter projects through an aperture in the dial and severs the laces against an anvil block slidable in a guideway in a bracket adjustably positioned by a solenoid. The braids are guided to the cutter by a finger 98 extending parallel to block and by a stop adjacent the block on the bracket. After severing the laces lie across a pin 101 on the bracket over a flexible deflector and over a pulley on an arm 105. The arm moves downwardly and outwardly and the braids engage fingers 241 and 243 and cam 245 on finger 241, the arm moves the finger inwardly displacing the laces from the pulley 104 and out of the path of the subsequent braids. The clamp 52 returns to its initial position, the jaws are opened by actuating solenoid 70<SP>1</SP> to grip the braids and the cycle of operations repeats. The mechanism is operated automatically by motor 15.

Filed: 1956-04-13
Abstract: Di-isobutyl malate is prepared by refluxing racemic malic acid with excess of isobutanol in the presence of p-toluene sulphonic acid as catalyst.  The water liberated and isobutanol are continuously distilled off and the water is separated from the azeotropic mixture before recycling the isobutanol.  Diisopropyl and diisoamyl malates are prepared by refluxing racemic malic acid with isopropanol and isoamyl alcohol, respectively, using p-toluene sulphonic acid as catalyst and benzene as reaction medium.  Optically-active esters may be prepared by substituting d or l malic acid for the racemic acid used above.  Reference is also made to esters prepared by esterifying the hydroxyl group of malic acid with acetic, propionic or benzoic acid and esterifying the carboxyl groups with isopropanol, isobutanol or isoamyl alcohol.  The esters are plasticizers (see Group IV (a)).ALSO:A plastic composition comprises a water-insoluble, organic film-forming polymer plasticized with a neutral ester of malic acid with isopropanol, isobutanol, or isoamyl alcohol, the alcoholic hydrogen atom of the malic acid being unsubstituted or substituted by a methyl, ethyl, acetyl, propionyl or benzoyl group.  Specified organic film - forming polymers are cellulose esters of saturated monocarboxylic acids of 2-4 carbon atoms, e.g. cellulose acetate of acetyl value 37-54%, polyvinyl acetate, polymethylmethacrylate, polyethyl acrylate and copolymers of vinyl acetate with vinyl chloride, vinyl propionate, isopropenyl acetate and the esters of acrylic, methacrylic, maleic, fumaric, crotonic, itaconic and citraconic acids.  Optically active neutral esters may be employed in the compositions, i.e. derivatives of d- or l-malic acid.  Films, moulding and other products may be made from such compositions.  In addition to the specified plasticizers above conventional plasticizers may be incorporated in compositions including a cellulose derivative, e.g. dimethyl phthalate, diethyl phthalate, dibutyl phthalate, dimethoxyethyl phthalate, triacetin, methylphthalyl ethyl glycollate, ethyl phthalyl ethyl glycollate, dibutyl tartrate, triethyl citrate, and acetyl triethyl citrate.

Title: Improvements in or relating to remote selection
Inventor: EDMONDS PETER HICKS
IPC: H04Q9/14
Filed: 1966-03-17
Abstract: 1,179,842. Electric selective signalling. ELECTRIC & MUSICAL INDUSTRIES Ltd. 17 March, 1967 [17 March, 1966], No. 11660/66. Heading G4H. One of a number of units is selected by a control station by transmitting over a number of parallel lines an address code, decoding means at the selected address giving an output when the corresponding address code is received which enables coded reply signals, identifying the address, to be sent back to the control station over the same conductors. The invention is described as applied to the control of hydraulic chocks in a coal mine. Each chock has a different address and one is selected by transmitting an appropriate combination of "1's" and "0's" over the eight leads 2‹-2<SP>7</SP>. The chock control circuit comprises a decoder comprising a series of diodes A1-A4, A7 and A8 acting as an Or gate connecting the "0" leads to the base of transistor VT1, and diodes A5, A6 connected to the "1" leads and acting as an And gate. If the correct pattern of digits is received a signal is applied to set a trigger circuit VT2, VT3. If a "1" is present on one of the "0" leads transistor VT1 conducts to connect the signal to ground so that the trigger is not set. When the trigger is set transistors VT6 and VT10 conduct and the circuit will now respond to interrogation which checks that the correct chock has been selected. Before interrogation an inhibit signal is applied to prevent any of the other chock circuits responding to the reply signals. The "1" digits are then checked by a signal on the "interrogate '1' " lead. This turns on transistor VT7 so that 9 v. is applied through transistor VT8 to diodes B5, B6 corresponding to the "1" diodes A5, A6. The "1" digits are detected at the control station. The signal on the interrogate "1" lead is then removed and a signal applied to the interrogate "0" lead to turn on transistor VT9 and apply a signal to the "0" diodes B1-B4, B7 and B8. These signals are also detected at the central station. Control signals may now be applied at the "Push valve supply" and "Advance valve supply" leads to control corresponding control valves, the circuits being enabled by the output from the trigger VT2, VT3. When a chock is selected the trigger output energizes a loudspeaker circuit by turning on transistors VT14, VT15. The output of VT15 applies a signal to an oscillator VT16, VT17 which supplies loudspeaker LS. If, when a chock is selected it is not properly set against the roof, a pressure switch SW1 is transferred so that transistor VT4 is turned on and a signal is sent to the control station on the "Chock not set" lead. A ram potentiometer RV1 is connected to the central station when a chock is selected, by transistors VT12 and VT13. If the switch SW1 is not operated it will cause the transmission of the "1's" of the address code to indicate at the central station that further adjustment is necessary before the chock can be operated.
