Patent GB-733465-A (GB)
Title: Polar relay
IPC: H01H51/22
Filed: 1953-08-14
Abstract: 733,465. Magnetic compositions. STANDARD TELEPHONES & CABLES, Ltd. Aug. 14, 1953 [Aug. 27, 1952], No. 22497/53. Drawings to Specification. Class 38 (2). [Also in Group XXXVII] In an electromagnetic relay, a ball constitutes an armature as well as a contact and moves into engagement with rod contacts which are also of magnetic material. Both the ball and the rods may be produced by powdered metallurgy techniques, a suitable mixture being tungsten carbide, iron powder and copper particles. After compacting and sintering a thin wrapping or wire of copper, silver, chromium or rhodium is wound round a rod which is then heated so that the wrapping melts and flows into any interstices. In place of or in addition to tungsten carbide, there may be used chromium or tungsten and in place of iron there may be cobalt or nickel.

Title: Improvements in photographic developing agents
IPC: C07D231/08
Filed: 1954-08-03
Abstract: The invention comprises pyrazolidones of the formula <FORM:0757271/IV(a)/1> where R is alkyl, hydroxyalkyl, carboxyalkyl, or aryl and R1 and R2 are alkyl (same or different), and their preparation from R.NH.NH2 and Hal-CH2-CR1R2-CO-Hal with an acid-binding agent mixed at 0-10 DEG  C. and then heated, e.g. to 100 DEG  C. for 1-10 hours.  Substituents in the aryl group R may then be modified, e.g. acyloxyalkyl, acyloxy and acylamino hydrolysed to hydroxyalkyl, hydroxy or amino respectively, or nitro reduced to amino.  Examples are given of the preparation of 1-phenyl-4 : 4-dimethyl-3-pyrazolidone, 1 - p - tolyl - 4 : 4 - dimethyl - 3-pyrazolidone and 1 - (p - b  - acetoxyethylphenyl) - 4 : 4 - dimethyl - 3 - pyrazolidone, hydrolysed to the b -hydroxyethyl compound.  The products are photographic developing agents, in which process they are oxidized to bimolecular compounds, probably bis-[1-(alkyl or aryl) - 4 : 4 - dialkyl - 3 - pyrazolidon - 5-yls]. The product from 1-phenyl-4 : 4-di-methyl-3-pyrazolidone is isolated. Other specified products of the invention are 1-(p-aminophenyl) - 4 - methyl - 4 - propyl - 3 - pyrazolidone, 1 - (p - chlorophenyl) - 4 - methyl - 4-ethyl - 3 - pyrazolidone, 1 - (p - acetamidophenyl) - 4 : 4 - diethyl - 3 - pyrazolidone, 1-(p - methoxyphenyl) - 4 : 4 - diethyl - 3 - pyrazolidone, 1 - (7 - hydroxy - 2 - naphthyl) - 4-methyl - 4 - propyl - 3 - pyrazolidone, 1 - (mchlorophenyl) - 4 - methyl - 4 - ethyl - 3 - pyrazolidone, 1 - (m - acetamidophenyl) - 4 : 4-dimethyl - 3 - pyrazolidones: 1 - (p - nitrophenyl), 1 - (p - cyanophenyl), 1 - (p - acetamidophenyl), 1 - (p - benzylphenyl), 1 - (pcarboxyphenyl), 1 - (m - aminophenyl), 1-methyl, 1-carboxymethyl and 1-hydroxyethyl.  Other groups specified for R are ethyl, propyl, isobutyl, carboxyethyl, o- and m-tolyl, o- and m - methoxyphenyl, p - dialkylaminophenyl, o- and m-nitrophenyl, bromophenyl, o-chlorophenyl, o- and m-carboxyphenyl, hydroxyalkylphenyl, hydroxyphenyl and a - and b -naphthyl.  b -Halofatty acid halides of the above formula are made from aldehydes CHR1R2-CHO by treatment with alkaline formaldehyde to give HO-CH2-CR1R2-CHO, oxidation to the acid HO-CH2-CR1R2-COOH and treatment of the latter with thionyl chloride.  Compounds in which R1 and R2 are identical can also be made from CH2-CR1R2-COOH and sulphuryl chloride.  The preparation of b -chlorotrimethylacetyl chloride is exemplified. Other products are mentioned.  p - (b  - Acetoxyethyl) - phenylhydrazine hydrochloride is made by diazotizing p-(b -acetoxy-ethyl)-aniline and reducing the product with stannous chloride.

Abstract: 717,424. Overload release positive clutches. MIAG VERTRIEBSGES. Sept. 27, 1951 [Oct. 3, 1950], No. 22552/51. Class 80 (2) A drive for bucket wheel sluices and like machines includes, between each bucket wheel and a common driving shaft, an automatic overload release clutch of the type which is so constructed that. if the torque required to drive one of the machines rises beyond a safe value, the bucket wheel sluice, &c. concerned is brought to a standstill without interrupting the drive to the other bucket wheel sluices, &c., the common driving shaft consisting of several removable shaft parts. such as 9, connected by axially disengageable and completely releasable couplings such as 10, 14 to succeeding parts 9<SP>1</SP>, &c. of the common shaft, each automatic overload release clutch having a coupling .sleeve 5, limitedly movably both axially and rotatably on its shaft part 9, held in the clutch engaged position by a spring 6. Torque is transmitted from the shaft 9 to the sleeve 5 by a pin 4 in the shaft engaging an L- or T-shaped slot 3 in the sleeve, which latter has teeth, &c. 2 co-operating with similarly shaped recesses in the runner 1 of the bucket wheel sluice &c. from which recesses the teeth ride out should the torque absorbed by the bucket wheel sluice become excessive. The pin 4 is then engaged with the circumferentially directed part of the slot 3 to hold the clutch disengaged. If the bucket wheel sluice is out of action for reasons which necessitate its having an extensive overhaul, the main drive may be stopped, the machine dismantled and its removable shaft part 9 or a similar substitute shaft inserted in the common shaft so that the drive may be recommenced to the remaining machines. Each disengageable coupling between succeeding shaft parts is constituted by the axially slidably' sleeve 10 having a slot 11. engaged by a pin 8 fast in the shaft part 9 and abutted by the spring 6, this sleeve having radial slots receiving one of two pins 14 in a universal joint member 13.

Abstract: 217,113. Nordstr÷m, O. Sept. 25, 1923. Filtering.-Dust is removed from gases by passing them through a filtering tower containing granular filtering material which is constantly removed, the whole of the purified gases being allowed to escape while the filtering material is cleaned as it leaves the base of the tower by passing it through a suction chamber communicating on one side with the atmosphere and on the other with a suction means which draws off the dust. Gas from a rotary cement furnace 1 passes along a conduit 5, through an annular filter comprising perforated walls 6, 7 between which granular material falls continuously, and along a conduit 10 to the chimney. The outer wall 6 of the annular chamber terminates above the bottom plate 11, while the inner wall ends in a conical plate 12 formed with air inlet openings 120 leading to the space 15 between the conical walls 16, 17 of a chamber which communicates with a fan 18 discharging into a dust separator 21.
