Title: Improvements in or relating to apparatus for drying sisal and similar fibrous materials
IPC: F26B15/22
Filed: 1948-12-17
Abstract: 651,388. Drying apparatus. PEROTTI, C., and BONOMO, P. Dec. 17, 1948, No. 32721. [Class 34(ii)] Apparatus for drying sisal and like materials has two vertical drying chambers in spaced parallel relationship through which containers or trays are moved successively, each chamber being flanked by a heating flue and an exhaust flue at opposite sides, the chambers communicating with each of the flues through a series of ports. Air, heated by heat exchange relationship with combustion products from a furnace, passes through the flues and chambers to dry the material. As shown, a tower structure has a furnace! 10 and hot gases and combustion products therefrom flow through a passage 12 into a flue 13 which extends upwardly in zig-zag formation through an air heating chamber 11 lying between the drying chamber 21, 22 and thence escape to the atmosphere. Air enters the chamber 11 by an adjustable inlet 15, flows downwardly through passages 16 in the flue 13, by contact with which it is heated, and is directed in a circuitous path by baffles 17 and passes into vertical heating flues 19, 20 through openings 18. Exhaust flues 23, 24 on the opposite sides of the drying chambers 21, 22 are, with the flues 19, 20 connected to the chambers 21, 22 by damper controlled ports 25, the latter being relatively staggered so that air flows upwardly or downwardly, its direction of motion being opposed to that of the trays 28. The air circulation is effected by a fan 26 communicating with the exhaust flues. The trays move progressively upwardly through one chamber, across the top of the chamber 11 and into the second chamber wherein they are moved progressively downwards to a discharge point at the bottom of the chamber. The temperatures of the drying chambers may be adjusted by controlling the entry of the hot air by adjusting the valves of the ports 25.

Title: Improvements in or relating to lace machines
IPC: D04C5/02
Filed: 1948-12-18
Abstract: 717,741. Lace machines. HALLCROFT ELECTRICAL & MECHANICAL APPARATUS CO., Ltd.; and WOOLLEY, E. Dec. 19, 1949 [Dec. 18, 1948], No. 32790/48. Class 74(1). A fault detecting and indicating means for a textile machine consuming a multiplicity of threads, comprises a movable detector incorporating a member common to a group of the threads and influenced by breakage or slackness of any of the threads, and electrical alarm means so influenced by the detector that the alarm means is operated to indicate such slackness only when the detector has been operated continuously for a predetermined period. When a lingot 1 of a lace machine descends it rests on a tray 102 and, by its weight, rocks levers 13 about a rod 4, against the action of counterweights 105, to close a mercury switch 7, adjustable by a spring 116 and screw 106. The rod 4 is carried by an arm 123 pivoted to parallel members 10, 110, themselves pivoted on a bracket 9, so that the unit as a whole may be pushed away from the lingot to facilitate repair of a broken thread. Operation of the alarm means before expiration of the predetermined period is prevented by an electrical time delay mechanism, AP BP A AL H Fig. 6, in which relays -, -, -, -, -, when 2 2 3 2 1 energized, operate to move the associated contacts from the full-line to the dotted-line positions. AP BP Relays - and - are slow-acting. When switch 2 2 AP S1 is closed, relay - is energized, to close contact 2 BP AP1 and so cause operation of relay -, after 2 about 150 milli-seconds, to open contacts BP1' AP causing relay - to release after an interval of up 2 to 40 seconds. This release will open contacts AP1, BP causing relay - to release, again after about 150 2 milli-seconds, so re-closing contacts BP1, Thus, since relays AP/2 and BP/2 control contacts AP2, BP2. a circuit controlling lamps LP1, LP2, and a bell BL is modified at regular intervals. If a mercury switch 7, indicated at MC1, closes after the opera- AP BP tion of relay - and before that of relay -, the 2 2 circuit of relay A will be made through contact BP2, contacts A2 will close to lock the relay A, contacts A3 will close to prepare the circuit of the alarm lamp LP1, and contacts A1 will close to H energize -, which will close contacts H, to 1 AL prepare partially the circuit of relay -. Opera- 2 BP tion of relay - will now move contacts BP2 to 2 the dotted-line position, to complete the circuit of AL relay -. If, now, the mercury switch remains 2 AP closed until relay - releases, contact AP2 will 2 BP resume the full-line position and, relay - not 2 AL having yet released, the circuit of relay - will 2 be completed through contacts AP2, BP2 and the relay will be locked by closing of contact AL2. The contact AL1 is simultaneously closed to complete the circuit through section lamp LP1, alarm lamp LP2 and bell BL. Switch CO is connected mechanically with the machine starting handle and prevents the bell ringing while a fault is receiving attention.

Title: Cooking apparatus for use with gas, liquid fuel or electricity
IPC: A47J27/62
Filed: 1920-11-29
Abstract: 154,604. Svenska Aktiebolaget Gasaccumulator. Dec. 3, 1919, [Convention date]. Thermostats.-The supply of gas, liquid fuel, or electricity for heating cooking-apparatus is adapted to be controlled by the effect of the steam generated in the heated receptacle on a thermostatic device which increases or decreases the gas &c. supply, and is applied to the edge of the receptacle so as to be affected by the steam flowing out through an opening near the edge. In the construction shown in Fig. 1, a fluid-containing casing affected 'by the steam communi. cates with a second casing 2 carrying a diaphragm 6 which, by seating on a shoulder 9 of the casing, serves as a valve to regulate the flow of gas or liquid fuel to a burner through the passages 7, 8. A spring 10 tends normally to press the valve away from its seating, and a small passage 11 allows a small quantity of gas &c. to pass to the burner when the valve is closed. The casing 1 may be attached to the side wall of the receptacle 12 or, as shown in Fig. 2, to the cover 13 by means of a balance arm 15 and a projection 16 which passes between the receptacle and its cover, so as to allow the steam generated to be directed on to the casing 1. In a modified construction, Fig. 5, the diaphragm 6 is combined with the casing 1 for controlling an electric heating-circuit, contacts 19, 20 normally in engagement, being mounted on the diaphragm and casing respectively, and adapted to break the heating circuit when the fluid in the casing 1 expands. In order to prevent sparking, the contact pieces 19, 20 are made of soft iron, and the contact 20 forms part of an electro-magnet, whereby a magnetic force is added to that of the spring 23 for keeping the circuit (closed. In a 'further construction, an element 26, such as a piece of wood, adapted to be deformed by the action of the moist steam, is mounted in a holder 25, and may act directly upon the gas tubing 27, or may indirectly, through the action of levers, control the supply of heating medium. The Specification as open to inspection under Sect. 91 (3) (a) comprises also that in the first constructions described, the casing 1 may be shaped in the form of an arc conforming the shape of the side of the receptacle so that a larger surface of the casing is exposed to the action of the steam. This subject-matter does not appear in the Specification as accepted,
