Title: A Hoist Brake Application Retarding Device
Inventor: WARRY REGINALD FRANK
IPC: B66D5/00
Filed: 1967-07-21
Abstract: 1,178,932. Winching apparatus; brakes; builders' hoists. MARTIN HOIST & ENG. CO. Ltd. 3 July, 1968 [21 July, 1967], No. 33783/67. Headings B8B and B8H. A device for retarding the speed of application of a winding drum brake in the event of overspeed of the drum or at the end of a wind, comprises a shock-absorbing unit 25 which is effective to slow down the movement of a linkage system 11, 14 controlling a combined brake and clutch arrangement for the drum 10. once the said linkage 11,14 has been unlatched from a further linkage system 16, 17 which normally controls the brake and clutch arrangemeat. The unit 25 mounted on the link 11 includes a plunger 26 on a rod 27 which is biased by a spring 28 outwardly of the unit cylinder, the latter having a small diameter orifice 30 and a large diameter pipe 24 for the exhausting of air from the cylinder during normal operation of the brake, whereupon the only retarding of the brake action is due to compression of the spring 28 as the rod 27 moves down to engage an abutment 29. Due to overspeed or at the end of a wind, a latch element 19 is pivoted on the link 17 out of engagement with the link 11 and an abutment 21 on the element 19 then releases a spring- loaded tap 22 on the link 11 into a position in which it closes the air pipe 24. Upward movement of the plunger 26 within the unit 25 and corresponding downward movement of the link 11, is therefore restricted by the airflow through the aperture 30, as the rod 27 engages the abutment 29. The latched linkage system 11, 14, 17 is normally lifted at one end by a control rope attached to an eye 18, to release the brake and engage the clutch, and is lowered by a weight 15 to apply the brake and disengage the clutch. During over-speed of the drum 10, a centrifugal device 31 engages a lever 35 to unlatch the element 19 via a rope 36. At the end of a wind, the element 19 is engaged by a load carrier, to unlatch the links 11 and 17.'

Class 1(1) In an apparatus for degasifying water, particularly boiler feed water, wherein a vessel is provided with a spraying device having circumferential holes in a cylinder through which the water is passed and the number of available holes is controlled by a slide valve, the holes are confined to opposed segments of the cylinder as shown in Figs. I and 2. Joined to the intervening segments are two sector-shaped plates 17 inclined downwards to below the water level at a similar angle to the water screen formed by water fed from pipe 5 and passing through the unmasked spray holes 6. One of the plates 17 is joined to the end wall 18 of the vessel and the opposite plate 17 is joined to the vertical arcuate partition 19 which extends to the circumferential wall of the vessel. Steam is introduced at the point indicated by arrow b so that it discharges below the water level 16 and rises upwards, heating the water screen and driving the gases out of the water, the gas escaping at one or more outlets 23 in the circumferential wall of the vessel above the sector-shaped water screens (see Fig. 2). The relative position of piston 7 and hence the number of holes unmasked is controlled by the difference in pressure of the water introduced at 5 and the steam introduced at b. Alternatively the piston may be controlled via a servo-motor by the water level in vessel 1. Specification 721,037 is referred to.

[Classes 2 (ii), 2 (iii) and 15 (ii)] Coloured-pigments are produced by dyeing a non-resinous precipitate as used in Specification 484,901 and obtained at a temperature not exceeding 60‹C., after it has been precipated. The non-resinous precipitate is the insoluble reaction' product of an aldehyde with urea or ammonium cyanate, thiourea, substituted ureas or urea-like substances, e.g., cyanamide, guanidine or semi-carbazide or bodies containing a similar NCN grouping, there being at least one free hydrogen atom attached to one of the nitrogen-atoms and including tantomeric forms of the substances capable of reacting with an aldehyde in the presence of a precipitant to form a non- resinous precipitate (but excluding ' aminotriazines). The non-resinous precipitate may be formed in the presence of an emulsifying, dispersing or protective agent as described in Specification 484,901. The coloured pigments may be used in the treatment of textile materials as described in Specification 484,901, by simple application or'by incorporation in artificial silk solutions before spinning. The precipitates may be dyed with vat, naphthol azo, sulphoricinoleic acid or other colours used for dyeing cellulose acetate artificial silks, direct, basic or acid colours. In examples (1) urea and aqueous formaldehyde are mixed, aqueous tartaric acid solution added, the whole allowed to stand and the precipitate filtered off, washed and dried ; the precipitate is dyed by immersing in a dye bath containing Indanthrene brilliant orange G.K., sodium hydrosulphite and caustic soda ; (2) semicarbazide hydrochloride is dissolved in water, aqueous -formaldehyde added, the mixture stirred to complete precipitation and the precipitate filtered off; it is dyed by immersion in a bath containing Caledon yellow paste, sodium hydrosulphite and caustic soda ; (3) a cotton fabric is padded with a solution of methyl or glycol cellulose in sodium hydroxide to which a dyed pigment has been added ; the fabric is then partially dried at a low temperature or treated with acid, it can be further treated by means of a hot calender. Specifications 435,767 and 487,835 also are referred to. In the Provisional Specification the pigments are obtained by colouring or simultaneously colouring and producing the insoluble non-resinous reaction products. A mixture of urea and formaldehyde may be added to the dye bath under non-acid conditions and precipitation effected by addition of acid in presence of the dye. The pigments can be used for incorporation with material used for making linoleum, resin blocks, paints and distempers.

Filed: 1935-12-09
Abstract: 464,492. Wireless receiving-apparatus. RADIOAKT.-GES. D. S. LOEWE. Dec. 9, 1935, No. 34103. Convention date, Dec. 10, 1934. [Class 40 (v)] Automatic gain control in a television receiver is effected by a special rectifier 13 independent of the usual rectifier 5 and amplitude filter 9. The rectifier 13 is excited by the synchronizing signal detected by the rectifier 5. The rectifier 13 is coupled to a lead 7 carrying the image potentials by a capacitative or inductive coupling which is preferably tuned to the synchronizing frequency and transmits no direct-current component so that the excitation of the rectifier 13 varies with the received field strength. The coupling may consist of a condenser 14 and resistance 15 of such a magnitude that detrimental capacities in the regulating rectifier do not affect the high-frequency potentials in the lead 7. A bias 17 on the circuit of the rectifier delays the initiation of the controlling action and is adjusted by varying the resistance 16 to produce the desired strength of reception. The detector 5 for the intermediate-frequency amplifier 2 is in the same bulb as, and directly coupled with, the filter 9 for separating the synchronizing signals, and the regulating rectifier is a separate valve, crystal detector, or contact rectifier. Specification 464,483 is referred to.
