Title: Improvements relating to a combination rocking and reclining chair
IPC: A47C1/0355
Filed: 1966-06-21
Abstract: 1,138,327. Seats. AMERICAN METAL PRODUCTS CO. 21 June, 1966 [21 June, 1965], No. 27597/66. Heading A4J. The moment exerted on a reclining and platform rocking chair to rock it about axis 5, in the upright position, is transmitted, by link 48 or a latch (78, Fig. 18, not shown), to rockable base 4, so that the chair can be rocked without altering its disposition. As soon, however as it has been moved, by rearward pressure on backrest 9, into one of the reclined positions, roller 54a is brought into contact with rail 55, fixed to platform 1, to terminate rocking action. Link 48 is simultaneously moved into an horizontal position, in which it is ineffective to transmit vertical thrust, or latch (78) is released. In the transition from the semi-reclined to the fully reclined position, the angle between the seat frame and back-rest is increased, to displace arm (58) forwardly, thus turning link 60 about pivot (66) to raise the front of the seat and to tension return spring (63). Leg rest 28, 29 does not fully participate in this movement, but is kept horizontal by link (42) turning about pivot 16. A modified rocking means (Fig. 19, not shown) is described.

Title: An automatic control arrangement for rudder steering gears
IPC: G05D1/02
Filed: 1951-11-28
Abstract: 709,307. Automatic steering systems. LICENTIA PATENT-VERWALTUNGSGES. Nov. 28, 1951 (Nov. 30, 1950], No. 27924/51. Class 38(4) [Also in Group XXXVIII] An automatic steering system applies one preselectable rudder angle for a variable time for all small deviations from course and a second preselectable angle for all larger deviations. Alternative manual steering is provided. The manual steering comprises a conventional powerassisted system, such as a resistance transmitter 13 and associated rudder follow-up 14 feeding the differential field 16 of a Ward-Leonard rudder drive (not shown). For automatic steering, deviation signals from, e.g. a compass, are applied to valves 19, 20 which operate relays 21, 22 respectively to apply a voltage through a preset resistor 18 to one side of the differential field 16 which causes a dsplacement as in hand steering until resistance 17 in the other arm of the field is adjusted to balance. Large deviations operate relay 27 to shunt the preset resistor 18 and cause a larger rudder displacement.

Title: Process and device for continuously measuring the carbon concentration of a bath of metal during refining by a gaseous blast in a refining vessel
IPC: C21C5/30
Filed: 1962-07-20
Abstract: <PICT:0965973/C6-C7/1> <PICT:0965973/C6-C7/2> In the oxygen-refining of crude iron the progress of the reaction is monitored by continuously measuring the volume of the gases evolved and their content of CO and CO2, and calculating continuously from these values the rate of carbon removal.  The calculating means may furthermore integrate the result to determine the amount of carbon removed, and may also, if adapted for the input of initial carbon content and charge weight, produce a continuous indication of the carbon remaining in the bath.  As shown in Fig. 1, gases collected in hood 3 are extracted through dust-removal plant 5 and fan 7, pressure inside hood 3 being maintained equal to that of the ambient atmosphere by differential pressure gauge 11, regulator 12 and valve 13, to minimize ingress of air.  The CO and CO2 contents of the gas are measured by infra-red analysers 16, 17, and total volume flow by flowmeter 22, the values being fed in the form of electrical voltages to computer 15 the output of which operates recorder 13.  In the modification of Fig. 3, hood 30 is arranged to admit an excess of air so that all CO is burned to CO2, and the gases are exhausted through heat exchanger 102. It is then only necessary to determine the CO2 by analyser 17, and it is preferable in this embodiment to measure change in total volume flow by Pitot tube 103 and pressure gauge 104, and to use this result to correct a previously determined nominal flow volume.

Title: Improvements relating to the colouring of asbestos cement and other products
IPC: C04B41/50
Filed: 1931-10-08
Abstract: Slabs and other articles made from cement and a fibrous material, e.g. asbestos, are coloured by applying a dry mixture of colour and cement and/or fibre to the moist article and consolidating by pressure.  The colour mixture may be applied uniformly or in patterns, e.g. through stencils.  As an example, in the manufacture of asbestos-cement sheets, a dry mixture of colour, asbestos, and cement is sprinkled on to the web just prior to its passing over the suction box, the suction drawing the coloured mixture into the wet felted mass.  The colour is consolidated by the pressure applied when the web is wound on to the forming roll.
