Title: Improvements in the manufacture of artificial textile materials
IPC: D06M13/188
Filed: 1935-10-02
Abstract: Fabrics and other products containing cellulose acetate or other artificial filaments lubricated with a salt of an alkylolamine and a higher fatty acid, are weighted by treatment with a water-soluble salt of a metal which forms an insoluble salt with the higher fatty acid.  Suitable alkylolamine salts are triethanolamine stearate, palmitate and oleate, and corresponding salts of propanolamine, butanolamine and dioxypropanolamine.  The metal salts may be barium chloride and cyanide, and calcium chloride.  By removal by solution of a part of the alkylolamine salt during the treatment, delustred products may be obtained, although avoidance of delustring may be secured by the addition of acetic or formic acid or other swelling agent to the metal salt bath.  The alkylolamine salt may be added to the spinning solution or may be incorporated in the filaments by a subsequent treatment.  The Specification as open under Sect. 91 refers to the use of salts which are lubricating agents.  This subject-matter does not appear in the Specification as accepted.

Abstract: 950,249. Converting oscillating into rotary motion; ratchet gearing. NATIONAL CASH REGISTER CO. July 17, 1962, No. 27356/62. Heading F2Q. Oscillatory movement of a handle 3 of a cash register or adding machine is converted into unidirectional rotation of a shaft 30 by means of pawls 16, 17 carried by plates 12, 13 fast with the handle 3 and alternately engaging recesses 19, 21 in ratchet wheels 20, 22 to drive the latter alternately in opposite directions, which wheels 20, 22 are respectively geared through an idler 25 and directly to the shaft 30. The handle 3 and a plate 9 fast therewith are biased by a spring 11 into one extreme position determined by a surface 34 on the plate 9 engaging a stop 33. In this position a spring 27 urges the pawl 16 into a recess 19 in the ratchet wheel 20 so that on anticlockwise, Fig. 1, rotation of the handle 9 against the action of the spring 11 the wheel 20 is rotated anticlockwise and drives through the idler 25 the shaft 30 anticlockwise. The anticlockwise rotation of the handle 3 and wheel 20 is limited to 90 degrees by a surface 35 of the plate 9 engaging the stop 33. In this position the spring 27 urges the pawl 17 into a recess 21 on the ratchet wheel 22 which is rotated clockwise when the handle 3 is released and returned to its original position by the spring 11. The clockwise rotation of the wheel 22 drives the shaft 30 in an anticlockwise direction. The sizes of the gears between the wheels 20, 22 and the shaft 30 are chosen so that for each 90 degree rotation of the wheel 20 or 22 the shaft 30 is rotated through 180 degrees. Diametrically opposite recesses 19, 21 in the wheels 20, 22 ensure that when one pawl is in engagement with one of its associated recesses the other pawl is only adjacent one of its associated recesses when the handle 3 is in one of its extreme positions. In Fig. 3 (not shown) a centrifugal governor driven from the shaft 30 prevents overspeeding of the latter. The Specification also states that a dashpot may prevent overspeeding of the shaft 30.

Title: Improvements in and relating to thermostatic selective heating, cooling and circulating interlocking control systems
IPC: F24F11/08
Filed: 1948-10-28
Abstract: 650,866. Automatic temperature control systems. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 28, 1948, No. 28036. Convention date, Oct. 30, 1947. [Class 38 (iv)] [Also in Group XXIX] In an air-conditioning system for a space 10, having an heater 30 and an air cooler 19 in an intake duct 12, electric or fluid-pressureoperated. thermostatic switching mechanism is provided for selectively operating the air heater or cooler upon temperature deviation from a predetermined value. An air circulator, comprising an electric motor 18 and blower 13, under the control of the thermostatic mechanism, is operated. jointly with the heater or cooler but is maintained in continuous operation after operation of the cooler until subsequent operation of the heater by means of a relay 75. The electric thermostatic switch may comprise a " heating " thermostat 50 and " cooling " thermostat 51, or may be of the single blade dual-contact type (Fig. 2, not shown). When the temperature of the space 10 falls below the predetermined value, thermostat 50 operates to energize a relay 52, thereby closing contacts 60, 64. Closure of contact 60 completes a circuit to fire a boiler 33 operating the heater 30. As the temperature of the air in the duct rises, contacts 72 and 74 of a second thermostat are closed, thereby energizing the motor 18 and blower 13 through line 80, contact 64, and line 81. As soon as the temperature in the space 10 has risen to the predetermined value the thermostat 50 de-energizes the relay 52, opening contacts 60, 64 and de-energizing the blower motor and boiler. If the temperature continues to rise the thermostat 51 causes a relay 57 to be energized, thereby closing contacts 66, 69. Closure of contact 66 completes a circuit to a refrigerant motor 29 operating the cooler 19. As the air in duct 12 cools down the contacts 72, 73 of the second thermostat are closed, thereby energizing the blower motor through line 88 and closed contacts 63, 69. Closure of contact 69 also operates the relay 75, thereby closing contacts 76 and completing a holding circuit so that when the space 10 cools to the predetermined value and relay 57 becomes de-energized, thereby de-energizing the refrigerant motor 29, the blower motor remains energized over closed contacts 76 until a subsequent operation of the heater thermostat causes contacts 63 to be broken. A humidistat 78 is provided for operating a humidifier 38 but is inoperative during periods when the relay 75 is energized owing to the action of a contact 77. The thermostat may be fluid-pressure-operated (Fig. 3, not shown) (see Group XXIX).
