Abstract: 639,915. Sewing-machines. BRANDWEIN & CO., A. Feb. 27, 1948, No. 6047. Convention date, Jan. 30, 1942. [Class 112] A sewing-machine comprises a carriage movable on a pair of ways on a supporting frame, means for intermittently feeding the work past the stitching mechanism, the carriage being adapted to produce relative movement between the work and the stitching mechanism transverse to the direction of feed, and reciprocating means connected with the carriage through lost-motion means rendering the reciprocating means ineffective so that the movement of the carriage is interrupted during feed. Feed.-In the embodiment shown, for making lines of stitching across strips of material forming mattress boxing, a sewing-machine 9 adapted to make stitches with any direction of feed is mounted on a carriage 8 which is moved back and forth along rails 6 to produce the lines of stitching, the work being fed from right to left after each movement of the carriage to position the successive lines ; the sewing-machine operates continuously so that no thread-cutting device or intermittent stop mechanism is required, and the successive transverse lines of stitching are made alternately in opposite directions and are connected by longitudinal lines placed alternately at one end and the other of the transverse lines. A single motor 11 drives the machine 9, the carriage 8, and a pair of geared rollers 61 which feed the work. The carriage is actuated by a pitman of adjustable length from a pin adjustable radially of a rotating disc 45, so that its initial position and length of movement can be varied ; the link has a slot engaging the pin, so that there is some lost motion at each half-revolution of the disc 45, during which the carriage 8 is stationary, and the feed rollers 61 are actuated during this dwell by a cam 77 engaging a lever 79 adjustably connected to a ratchet arm 85 driving the lower roller. Presser wheels : work-guides.-A slightly-inclined presser-wheel with a rounded edge is carried close to the needle on a spring-loaded presser-bar. The work passes between a pair of rollers carried by standards 55, the top roller being spring-loaded, on its way to the sewing-machine, and then passes under a set of holding-down rollers 95 carried on arms 97 pivoted on brackets 90 on the standards 55 ; the set comprises a central roller extending over most of the width of the work (which may enclose padding) and bearing on the work by its own weight, and two side rollers on spring-loaded arms.

Title: Controlling the humidity of a gas
IPC: F24F6/12
Filed: 1963-02-14
Abstract: In a method of regulating the humidity of a gas between an upper and a lower limit the humidity of a part stream of the gas is altered to a controlled extent which is less than the range between the upper and lower limit and the part stream of the gas is passed over a humidistat adapted to operate a device for correcting the humidity of the gas whose humidity is being regulated, thus causing a reduction in the change of humidity required to make the humidistat operate and increasing the effective sensitivity at either the upper or lower limit.  In a described application a motor driven fan exhausts the part stream from the main stream and passes it over a heating element, the arrangement including a humidifying device for increasing the humidity of the gas under control of the humidistat traversed by the heated part stream.

IPC: C07C15/02
Filed: 1930-02-25
Abstract: Cyclic hydrocarbons are obtained by treating phenols in an autoclave with finely divided or spongy iron and water at a temperature of the order of or above 400 DEG  C., the amount of water presence being such that pressures of the order of 200 atmospheres or above are developed.  When higher homologues of phenol are treated products resembling terpene hydrocarbons are obtained. When pure phenol is treated, in addition to cyclo paraffins, condensation products are produced, the product boiling above 360 DEG  C. being suitable as a lubricant.  Gaseous hydrocarbons are also formed.  The formation of condensation products may be prevented by admixture with the phenols of other oils, preferably such as are obtained by or are capable of hydrogenation, for example, tar oils or their hydrogenation products. Materials containing cresols obtained from brown coal or brown coal generator tar may be used as starting materials.  In an example cresol is heated for an hour with water and finely divided iron in an autoclave, at 450-470 DEG  C., the product containing 30-40 per cent of hydrocarbons boiling up to 180 DEG  C.

[Class 40 (iv)] In a double modulation carrier system, two or more signal bands modulate a common oscillation, a single sideband of each modulated oscillation being selected and combined in pairs of upper and lower sidebands to modulate further oscillations, each of a different frequency, a single upper or lower sideband of each further modulated oscillations being finally selected. As shown, four kc/s. signal bands, each band comprising one 2.4 kc/s. speech channel and up to eight 120 c/s. telegraph channels, are applied to input terminals T1 to T4 and modulate at mixers M1 to M4 a common 8 kc/s. oscillation derived from an oscillator O1 High and low-pass filters F2, F1 select respectively an upper and a lower sideband of the modulated oscillations from mixers M1 and M2, the selected sidebands being combined at a mixer M5 to modulate a 208 kc/s. oscillation derived from an oscillator 02. An upper and a lower sideband of the modulated oscillations from mixers M3, M4 are similarly selected by filters F5, F6 and modulate at mixer M6 a 240 kc/s. oscillation from an oscillator 03. Band-pass filters F3, F7 select respectively the upper and lower sidebands of the double modulated carrier oscillations from mixers M5, M6, the selected sidebands being combined and connected through an amplifier A, a directional filter DF and a coupling filter F4 on to a power line P. Similarly derived sidebands produced at a distant station and operating in other frequency ranges are connected through the coupling filter F4 and a directional filter DF2 to an attenuator unit AU. The signal bands are then separated from the carrier by double demodulation in a circuit similar to the modulation circuit, the oscillators 04, 05 operating however at the same frequency as the double modulation stage oscillators at the distant station. The coupling filter F4 includes a band-pass filter F8 covering the whole of the carrier frequency ranges and tuned chokes F9, F10 for directional transmission. The 8 kc/s. oscillator O1 is common to the transmitting and receiving circuits of all signal bands. The apparatus may be arranged to transmit any number of signal bands from two upwards. The Specification also refers to the use of the frequency spacing between the upper and lower sidebands to transmit other signal bands within this band width along adjacent power lines. According to the Provisional Specification a fault protection circuit for a circuit breaker may be connected to the coupling filter F4.
