Title: Improvements relating to electrical devices for producing a controlled and reversibleforce or movement in a linear direction
Inventor: HAMILTON RALPH FREDERIC GILBER
IPC: H01F7/122
Filed: 1961-03-21
Abstract: 1,008,735. Electromagnets. ELLIOT BROS. (LONDON) Ltd. June 21, 1962 [March 2], 1961], No. 10243/61. Heading H1P. A linear movement of shaft 1 occurs when the number of lines of flux traversing air gaps 13, 14 changes due to coil 11 being energized, the direction of movement being such as to equalize the air gap flux densities. In the unoperated position annular permanent magnets 4, 5 produce fluxes # m1 , # m2 , Fig. 2 (not shown), which cross air gaps 13, 14 between pole pins 8, 9 and armature 12 and return through end plates 6, 7 so that armature 12 will move to the balance position where the flux density in each air gap is the same. When coil 11 is energized an additional unidirectional flux is produced which will boost the flux density in one air gap and reduce it in the other and the armature will move in a direction necessary to equalize the air-gap flux densities. If the current in the coil is reversed the shaft will move in the reverse direction and the force produced will be proportional to the exciting current. The permanent magnet flux paths may change due to the additional flux and thus further increase the flux in one air gap, Fig. 4 (not shown). In a modification, a single central permanent magnet may be used with two separate exciting coils, Fig. 5 (not shown) and the shaft may be made of uniform external diameter under the poles and end plates, the intermediate portions being of reduced diameter. In a further modification, the light-weight low-inertia armature comprises a hollow concentric polepiece attached by non-magnetic supports to the shaft and moving under the influence of the magnetic field produced between the longitudinally extending annular magnets and polepieces.

Title: Dealkylation of branched-chain ªÐ-alkylated phenols
IPC: C07C37/50
Filed: 1960-03-24
Abstract: Phenols containing a secondary or tertiary alkyl group in the p-position are dealkylated by heating them with an aluminium phenoxide in a proportion of 0.1-10% by weight (based on aluminium content) at 150-400 DEG C. at a pressure up to about 10 atm. for a period of at least 1 hour. The process may be applied to mono- or polycyclic mono- or polyhydroxy phenols which may be further alkylated, reference being made to the treatment of o- and m-cresols, xylenols, ethylphenols, cyclohexylphenols, benzylphenols, phenylphenols, naphthols, hydroxyanthracenes and hydroxyphenanthrenes, all containing a branched-chain alkyl group in a p-position. Specified compounds which may be treated are 4-isopropylphenol, 4-sec.- and 4-t butylphenol, 4-t.-butyl-o-cresol, 4-(1,1-dimethylbutyl)-o-cresol, 2,6-dimethyl-4-t.-butylphenol, 2,5-dimethyl-4-t.-butylphenol, 2-ethyl-4-t.-butylphenol, 2-methyl-6-ethyl-4-t.-butylphenol, 2,6-dimethyl-4-(1,1,3,3-tetramethylbutyl) phenol, 4-sec.-nonylphenol, 2,4-di-t.-butylphenol, 4,6-di-t.-butyl-o-cresol, 2-ethyl-4, 6-di-t.-butylphenol, 2, 4, 6-tri-t-butylphenol, 4, 6-di-t.-butyl-m-cresol, 2, 4-dinonyl-phenol, 4,6-dinonyl-o-cresol and 2, 4-di-(1,1,3,3-tetramethylbutyl) phenol.  The process is particularly applicable to the treatment of the butylation products of o-cresol from which 6-t.-butyl-o-cresol is to be recovered as the primary product and in this case, after separating the primary product by distillation, the residue containing 4-t.- and 4,6-di-t.-butyl-o-cresol is dealkylated as described above to yield o-cresol and isobutylene for re-use.  The aluminium phenoxide may be pre-formed or produced in situ from metallic aluminium and a phenol, preferably the phenol to be dealkylated or the expected dealkylation product.  Examples are given in which (1) p-t.-butylphenol yields phenol and isobutylene, (2) 4-t.-butyl-o-cresol or a mixture of 4-t.-and 4,6-di-t.-butyl-o-cresol yield o-cresol and isobutylene, (3) 4,6-di-t.-butyl-m-cresol yield m-cresol and isobutylene and (4) 4,6-dinonyl-o-cresol yield o-cresol and nonenes.

Title: Improvements relating to latch controlled uniselectors
IPC: H01H67/06
Filed: 1949-04-22
Abstract: 660,926. Automatic exchange systems. SIEMENS BROS. & CO., Ltd. March 31, 1950 [April 22, 1949], No. 10779/49. Class 40 (iv). The circuit arrangements of a latch - controlled uniselector, such as that described in Specification 388,173, are modified to ensure that the latching members engage smoothly even when the switch is stopped on its first contacts or is driven stepwise so that it does not reach its normal running speed. In this case a resistance is inserted into the circuit of the latch magnet to bring about a release of the magnet which is slower than it would be if the circuit were opened. In Fig. 1, for normal hunting, the closure of a starting contact s energizes the latch magnet LM to start the motor which drives the switch until the desired position is reached, whereupon a high speed test relay is operated to open a contact t and release the latch magnet. If it is known that the switch is to be stopped on its first contacts, a relay contact x is closed and the subsequent operation of the test relay places a resistance R in series with the latch magnet LM, delaying its release sufficiently for the latching members to engage smoothly at the lower running speed. In Fig. 2, if the switch is to be driven stepwise in response to impulses, earth is not connected to contact t and each closure of the impulsing contact p energizes the latch magnet LM over a switch wiper W whose contacts are interconnected. Between contacts the latch magnet LM holds in series with the low-impedance left-hand winding of a highspeed relay AT which operates and switches in its right-hand winding and a resistance R to cause delayed release of the latch magnet. Relay AT holds over its right-hand winding until contact p opens, ensuring that the switch takes only one step for each impulse. A spark quenching circuit SQ is provided. For hunting, earth is withheld from contact p and connected to contact t which is controlled by a high-speed relay as described with reference to Fig. 1. In a modification, Fig. 3, the relay AT is differential and operates when the wiper W in leaving its contact breaks the circuit for the right-hand winding.

Title: Improvements in wrapping machines
IPC: B65B11/32
Filed: 1928-04-12
Abstract: 315,024. Marks, E.. C. RÀ, (Package Machinery Co.). April 12, 1928. Packeting by wrapping-up.-In a machine for wrapping blocks of plastic material, such as yeast cakes, in tin foil and the like, an assembly B of the articles is placed on a conveyer belt 19, Figs. 1 and 4, which advances them so that the foremost can be gripped by members 78. The members 78 are yieldingly mounted on vertical shafts 77 geared together and adapted to be advanced and retracted by a horizontally reciprocable slide 86. Previously to the gripping and transfer of the article, a wrapper w has been fed in front of a pocket 101<1> in a wrapper wheel 101 by grippers 122, 125, Fig. 2, and is held in position by being clamped between a plate 149 and yieldingly mounted clamps 144. The wrapping material is fed from a roll W, Fig. 1, by feed rolls 104, 105 beneath a weighted roller 110 and over a guide plate 111 to shears 112 which sever a length. Grippers on a frame 121 on a vertically reciprocable slide seize the web at the side and drawit downwards so that the wrapper, when severed, is held between clamps 144, Figs. 1 and 4, and a plate 149. The wrapper grippers return to their upper position by an outward path so as not to interfere with the action of the article grippers 78. The article grippers carry the article and wrapper into a pocket 101<1> in the wheel 101 as shown in Fig. 5, the clamps 144, which are resiliently mounted to engage the wrapper opposite the forward sides of the grippers 78, moving backwards with the assembly. As the forward, upper, and lower edges of the grippers 78 are conterminous with the adjacent edges of the article so as to form flush extensions thereof, mutilation of the article, is thus avoided. The grippers move away from the ends of the article during their withdrawal from the recess. The wrapper and article are now as shown in Fig. 11. The flap b is folded down by a member 153 operated in a downward convex curved path in relation to the article so as to clear the upper corner of the article and yieldingly press the wrapper on to the rear face. During the first intermittent rotation of the wheel 101, a folding blade 152 and brush 166 turn up the flap b, Fig. 11, so that an open-ended tubular formation of the wrapper is produced. At the next position of rest, vertically moving end folders 160 make the end folds shown in Fig. 13, blades 157 turn in the first corner tucks f, Fig. 14, and, at the next rotation, fixed members turn in the second corner tucks g. A slot 168 turns down the last flap i to complete the folding. On arrival at the uppermost position of travel, the packet is transversely ejected into a delivery shoot.
