Title: Improvements in and relating to spacebands for matrix composing and type line casting machines
IPC: B41B11/00
Filed: 1934-02-26
Abstract: 419,638. Type-bar-making machines. FEENY, V. F., 73A, Queen Victoria Street, London.-(Intertype Corporation; 360, Furman Street, Brooklyn, New York, U.S.A.) Feb. 26, 1934, No. 6217. [Class 100 (iii).] Spacers.-The short wedge-member E, Figs. 1 and 4, of a spaceband especially suitable for hand composition has at least one projecting ear G at or near its lower end. The necessity for assembling matrices and spacebands at different levels in a hand composing-stick is thereby avoided. One of the ears G underlies the usual matrix-aligning rail P, Fig. 3, of the first elevator, and the wedge-member is thereby held against upward movement during justification. The usual upper ears of the wedgemember, which engage grooves R, S in the elevator and prevent upward movement, can therefore be replaced by ears F, which correspond to the upper ears of a matrix, and rest on the usual matrix-supporting rails J, K. When a line is assembled on a hand composing-stick T, Fig. 4, comprising two walls at right-angles to each other, the lower ears of both the matrices and the spacebands are aligned by a common rail U. The short wedge-members are preferably bevelled at the upper end, to facilitate their entry between the matrices. Spacebands for use with matrices of abnormal length' may have short wedge-members of corresponding length, the lower lugs being then located above the lower ends of the wedge-members. Specification 14582/90, [Class 100], is referred to.

Patent GB-629118-A (GB)
Title: Manufacture of hydrophenanthrene monocarboxylic acids and derivatives thereof
IPC: C07C62/32
Filed: 1947-03-06
Abstract: Hydrophenanthrene monocarboxylic acids and derivatives thereof are made by converting the carboxyl group of the fatty acid residue in a hydrophenanthryl-1-fatty acid (which contains in the 7-position a substituted hydroxyl group and in the 2-position an alkyl residue and an esterified carboxyl group) into an acid halide group, reducing this first to an aldehyde group and then to a methyl group, and if desired hydrolysing the groups in the 2- and 7-positions; the products may be esterified, etherified and converted into salts.  The starting materials may be obtained by partial hydrolysis of diesters of the corresponding 2-carboxy-hydrophenanthryl-1-fatty acids, the latter being obtained by the oxidative degradation of steroids.  The starting materials are heated with oxalyl chloride to yield the acid chloride and the latter reduced to the aldehyde by treatment with hydrogen in the presence of a catalyst (e.g. palladium).  The aldehyde may be isolated by conversion into the pyridiniumacetic acid hydrazide.  Reduction of the aldehyde group to a methyl group may be effected with zinc and hydrochloric acid, with chromous salts, or with hydrazine and an alkali alcoholate (or glycolate); alternatively, the reduction may take place indirectly via the hydrazone or semi-carbazone.  The product may be obtained in the optically-active or racemic form, and may be converted into a therapeutically-active stereoisomer.  Examples show the preparation of the 1-ethyl-2-methyl-tetrahydro -, 1 - ethyl - 2 : 13 - dimethyl-dodecahydro, 1 - ethyl - 2 - methyl - octahydro-and 1 - propyl - 2 - methyl - tetrahydro - compounds, and the use of a hydrophenanthryl-1-formic acid is mentioned as a starting material. The Specification as open to inspection under Sect. 91 is not confined to compounds substituted in the 7-position or carrying an alkyl substituent in the 2-position and mentions also as starting materials (a) compounds with a free hydroxyl group in the 7-position, and (b) compounds containing in the 2-position any substituent convertible by hydrolysis into a carboxyl group, e.g. acid amide or nitrile group.  Alternative methods of converting the aldehyde group into a methyl group are via the carbinol, p  thioacetal and dihalide. In a modification of the process, the acid halide is converted into a thioester and the latter catalytically reduced.  This subject-matter does not appear in the Specification as accepted.

[Class 138 (ii)] [Also in Groups II and XXXII] The centrifugal drying, or spinner basket 71 of a domestic washing-machine discharges into an annular trough 26 communicating through an aperture 32 with the wash tub 1, and an overflow pipe 40 drains the trough and controls the liquid level in the tub. The overflow pipe is connected to the suction side of a pump 41, which is continuously driven by a motor 47, and discharges to a drain. The pump is also. connected with the bottom of the tube by way of a pipe 49 and a manually-operated dump valve. An oscillating agitator 58 in the tub is driven by means of a crank arm 63, connecting rod 64, eccentric 65 and belt gearing 66, 69 and 70 from the motor. The rim of the spinner basket overlaps the trough 26 at 72, and has discharge apertures 74 in an annular cover 73. The basket has its moment of inertia about its axis of rotation increased by a balance ring 75, and it is resiliently carried by a spring-steel ring 76 having a three-point connection with the basket and also with a three-armed spider 79 on a shaft 80. This shaft is journalled in a sleeve 81 secured to a hemisphere 84 which is mounted to swivel on a fixed hemisphere 85 against the action of a rubber ring 87 and under the control of friction linings 86 between the hemipheres. By this means static unbalance is neutralized by the tilting of shaft 80 against the rubber ring 87, and dynamic unbalance by tilting of the basket relative to shaft 80 as permitted by the spring ring 76. Gyroscopic precession is damped by the friction linings 86. The drive to shaft 80 is by way of resilient couplings 95 and 99, an intermediate shaft 91, and a friction pulley 92 which can be engaged either with the motor pulley 46 or a fixed brake block 109 by operating a lever. The whole mechanism is carried by a frame 11 bolted to a sheet metal skirt 3 in which the tub 1 and spinner basket casing 2 are seated.

Abstract: 762,211. Automatic shuttle changing. BUTIN, E. A. March 5, 1954 [March 24, 1953], No. 6564/54. Class 142 (2). Shuttle changing is effected with the shuttle box disconnected from the slay and kept at back centre, the mechanism being actuated by a continuously-rotating cam shaft 42 mounted in the loom frame. During normal running, a cam 47 operates a cop feeler (not shown) through a follower 57, link 58, and lever 59, and a cam 52 operates the shuttle box swell (not shown) through a follower 61, link 62, and lever 63. When the feeler detects weft depletion, it releases a lever 75 coupled by a link 74 to an arm 73 on a shaft 69, allowing a follower 72 to enter a cam groove 48, whereby the shaft 42 is moved endwise; this movement is permitted by a notched disc 49, which passes over a stud 100 and prevents return movement of the shaft for one revolution. A cam 53, acting through a follower 64 and link 65, pulls arms 82 downwards, whereby a locking rod 93 is disengaged from lugs 94 on the slay 92 ; as the slay swings forward, it leaves the shuttle box 46 at rear centre, where it is located under the shuttle magazine by a roller 96 co-operating with a cam 54. Depression of the arms 82 also rocks a shaft 78 on the back of the shuttle box, causing a link 86 to lift a latch 87 clear of a rod 80, and causing a nose 99 to press on lugs 97 on the shuttle box wall 83 to open it. Meanwhile, an arm 76 on the shaft 69 has pulled a link 77 to release a shuttle from the magazine; a cam 56 acting through a follower 66 and a link 67, causes L-shaped stirrups to lower the fresh shuttle into the shuttle box, the movable wall 83 being slotted at 103 to clear the stirrups. At this stage, a cam 51 raises the arm 73, whereupon the parts return to their normal positions, the shuttle box closing and being re-coupled to the slay when the latter reaches rear centre. Specification 644,363, and French Specification 1,054,627 are referred to.
