Title: Confectionery coating compositions
IPC: A23G3/34
Filed: 1960-05-03
Abstract: A confectionery coating includes hard fat containing, in dispersion and substantially free from soaps, sugar esters of fatty acids having 10 to 24 carbon atoms per molecule, there being 1 to 8 acid radicals in each molecule of said esters.  Preferably 0.5% to 10% and usually 1% to 5% of the ester, based on the hard fat content, is used.  With hard butters formed by esterification of fatty acids with glycerine, sucrose tri- and hexa-stearate are preferred whereas, with hard butters made by the molecular rearrangement of the glycerides of fatty oils, sucrose mono- and di-palmitate are preferred.  Sucrose, di-, tri- and tetra-stearates are used with hard butter made from the glycerides of a coconut-type fat and a vegetable oil containing combined fatty acids with 16 to 18 carbon atoms per molecule. Sucrose di- and octa-stearates are used with mixed hard butters and sucrose tristearate with hard butters compatible with cocoa butter and chocolate liquor.  Mono-and dipalmitate sucrose esters are satisfactory with hard butters of high softening point.  The sugar esters of fatty acids with 14 to 24 carbon atoms, which are preferred from the point of view of stability colour and odour, are solids and have to be melted before being added to the hard butter.  The sugar esters of fatty acids with 10 to 12 carbon atoms per molecule are sufficiently soft to be mixed in cold.  In an example, a coating composition is made from the following (parts being by weight): 197.5 parts hard butter, 2.5 parts purified sugar ester, 400 parts of a mixture of sugar, cocoa and flavouring and 1.25 parts lecithin.  The results of a series of tests on the coating, when made with different esters, are given.

Title: Improvements in and relating to prepayment meters
IPC: G07F15/06
Filed: 1937-06-07
Abstract: 485,815. Prepayment mechanism for meters. BRITISH THOMSON-HOUSTON CO., Ltd. June 7, 1937, No. 15737. Convention date, June 6, 1936. [Class 27j Mechanism for collecting basic charges ; indicators.-A prepayment meter is provided with an additional differential gear between the coin and quantity mechanisms, which gear registers, and subsequently secures payment for, arrears of basic charge which accumulate after prepayment is exhausted. As shown, a sun-wheel 1 of the quantity mechanism is driven jointly by the commodity meter and a constant speed motor, whilst the planet shaft 2a carries a switch tripping element 3 and a pointer 4 showing the credit standing to the consumer. The coin operated sun-wheel 7 is connected through gears 8 and 9 to a sunwheel 10 of an additional differential gear whose other sun-wheel 14 is connected with the coin mechanism, and whose planet shaft 11a carries a pointer 12 indicating arrears of basic charge. Locking devices 16 and 17 prevent accidental rotation of the sun-wheels 7 and 10. When prepayment is exhausted, the pointer 4 engages a fixed stop 6 at its zero position, and the shaft 2a is arrested after having tripped the supply switch. The continued drive of the constant speed motor is then transmitted from the sun-wheel 1 through planet pinion 2 revolving on its own axis, sunwheel 7, gears 8 and 9, and sun-wheel 10 to the planet shaft 11a, the pointer 12 moving away from its zero position as arrears of basic charge accumulate. When further prepayment is made, the rotation of the sun-wheel 14 is first transmitted by the planet pinion 11 to the shaft 11a, the sun-wheel 10 being held by stop 17 so that no drive is transmitted to the quantity mechanism. When arrears of basic charge have been paid, the pointer 12 engages a stop 15 at its zero position and shaft 11a is secured against continued rotation. Further operation of sun-wheel 14 is then transmitted through the planet-pinion 11 revolving on its own axis, sun-wheel 10, and gears 9 and 8 to the sun-wheel 7 of the quantity mechanism whose shaft 2a is rotated to allow a further supply of electricity. In the modified arrangements of Figs. 2 and 3 (not shown), the two differential gears are arranged coaxially. The arrears indicator 12 is in the form of a graduated disc rotatable behind an aperture in a fixed plate, over a scale on the front of which the credit pointer 4 works, being coaxial with the arrears disc.

Abstract: 221,581. Bradshaw, C., and Sherston, G. W. June 19, 1923. Shuttle-changing mechanism.-When the weftfork mechanism operates to turn a'shaft j<1>, a pin 4 on an arm 5 on an arm 6 on this shaft raises a catch 3 on a spring-controlled lever x, u into the path of a projection 10 on a lay arm 11. The lever x, u is thus turned and a slotted bell crank lever 8 pivoted on the lever x, u and engaging a pin r on a plunger q operates this plunger to transfer a shuttle from the magazine into the shuttle box under the raised front b thereof. A spring-controlled catch-rod 12 carried by a pivoted bracket 13 is raised by a spring-controlled plunger 15 resting on the catch 3 into position to engage a rod j connecting pivoted bent arms g. Arms k on the rod are thus caused to raise guide-pins &c. c against the action of one or more springs, and thus to raise the shuttle box front b, which is attached thereto and slides upwardly in guideways in the lay to allow the fresh shuttle to enter beneath it. An adjustable arm 19 on the lay next contacts with an inclined face 20 on the bracket 13 thereby depressing this and disengaging the catch 12 from the rod j. The springs then return the box front to normal position. A spring w connecting the levers s and u, x, yields in case of obstruction. The arm 6 carries a spring-controlled hook 7 operating in conjunction with a hooked member 8 to move the pivoted box back into position to deflect the old shutle from the shuttle box.
