Title: Improvements relating to radio directional apparatus
IPC: G01S13/86
Filed: 1953-08-04
Abstract: 726,392. Radar. GENERAL ELECTRIC CO. Aug. 4, 1953 [Aug. 9, 1952], No. 21532/53. Class 40 (7). In a ground radar displaying the plan position of aircraft, the bearing of a particular aircraft transmitting a frequency different from that of the radar is displayed as an intensified radial line on the P.P.I. by a separate directionfinder whose aerial rotates at a speed of f2= 1800 r.p.m., which is greater than the speed of rotation, f1 = 30 r.p.m., of the radar aerial, the signals from the direction-finder being recorded on an annular magnetizable strip or wire recording element 34 by a recording head 32 rotating relative to the element at a speed of f2 and the recorded signals being applied to the cathode-ray tube by a pick-up head 43 rotating relative to the element at a speed of f r.p.m. As described, the pick-up head is stationary and the recording head and element rotate in opposite directions at speeds of (f2 - f1) and f1 respectively, but alternatively the element may be stationary and the two heads rotated in the same direction at speeds of f2 and f1 respectively. As shown, the radar aerial 10 and the D.F. loop aerial 21 are rotated by motors 18, 24 controlled from a power supply 19 by units 20, 25, the magnetic element 34 and time-base coil 16 of the display cathode-ray tube 14 being rotated synchronously with aerial 10 at a speed off and the radial arm 33 carrying the recording head 32 being rotated at a speed of (f2 - f1 ) by the output shaft 42 of a differential 38 whose input shafts 39, 37 rotate synchronously with aerials 10 and 21 at speeds of f1 and f2 respectively. The output B from the D.F. receiver 23 is applied via amplifier 27, rectifier 28, clipper 29 (pulse output D), and slip-rings 31 to the recording head 32 and the output from the pick-up head 43 is shaped and differentiated at 45, 46 (outputs E and F) to trigger a monostable flip-flop 47 giving a pulse output G of duration twice that of the sweep waveform A, which is applied to intensify the cathode-ray trace. Alternatively the waveform F may condition the flip-flop 47 so that it is triggered by the succeeding sweep waveform, the duration of the output G being then equal to the sweep waveform A. An erasing head 49 energized from A.C. source 50 is located adjacent the pick-up head. Magnetic recorder. As shown in Fig. 2, the magnetic tape 34 is wound round the cylindrical flange 58 of a disc 55 attached to a shaft 51. The pick-up head 43 is fixed outside the flange 58 and the recording head 32 is mounted inside the flange 58 on a disc 59 rotated by the output from differential 38 via gearing 67, 63, 65 and 66, the head 32 being dynamically balanced by a counterweight 61. In a modification, Fig. 3 (not shown), the magnetic tape is replaced by a wire embedded in the flange 58.

Title: Improvements in gravity ways for the conveyance of parcels and other goods
IPC: B65G9/00
Filed: 1919-09-04
Abstract: 161,998. Doherty, J. H. Sept. 4, 1919. Mechanical dispatch apparatus.- Relates to gravity ways suitable for conveying small parcels, and, in particular, mail packets in large post offices, in which a carriage can be loaded at a low lever, hoisted up to the track, sent along the latter to its destination, automatically discharged, and returned to the starting-point. As shown in Fig. 1, the runway consists of an upper track 9 sloping downwards towards the discharge end, with a counterweighted pivoted portion 13, and an extension 15, which guides the carriage on to a lower track 10, inclined downwards to the loading end. The hoist, shown at the right-hand side of Fig. 1, consists of a short length of track 5, fixed to a bracket pivoted on a frame w, and is raised by hand or power hoisting-gear 2. The weight of the carriage causes the short track 5 to tilt, as shown, thus retaining the carriage. When the short track 5 adjoins the upper track 9, it becomes tilted oppositely, setting the carriage in motion alc.ng the track. The carriage, as shown in Fig. 8, is carried on grooved wheels v, and is pro. vided with a hinged counterweighted bottom b and an end c hinged at e and fitted with an arm f pivoted at g. At the discharge end, the arm f is moved sideways by a bar inclined to the track, releasing it from catch i, and it then comes in contact with a stop, releasing the catch n, and allowing the bottom to open and discharge the contents. The bottom is raised bv the counterweight q, and the catches n, i are replaced by counterweights. The carriage then returns along the lower track 10 to its starting-point, where it runs on to the short track 5, which has already returned from its higher position. The hoist alone is heavier than the weight 26, and is perniitted to fall until opposite the lower track, whereupon the weight 25 functions. The hoist and carriage can finally descend against the action of the combined weights until the loading position is reached.

Title: Improvements in methods and machines for forming bodies by compression
IPC: B30B11/04
Filed: 1926-09-03
Abstract: 281,406. Claus, C. Sept. 3, 1926. Stationary-mould machines. - Bodies formed by compression and having varying thickness in the direction of compression are made by causing such compression to be so graduated that the parts of lesser thickness are not excessively compressed before the other parts. For this purpose granular material is poured into a mould space 11 in a block 10 which is closed at the lower end by an inner fixed core 14, an intermediate reciprocating die 13 and a resiliently mounted outer auxiliary die 35. An upper die is mounted on a sliding head 16 and on reciprocation of the dies in opposite directions, Fig. 3, the material is compressed to form a hollow shaped body, the auxiliary die yielding at the first part of the compression so as not to compress unduly the lesser thickness in the direction of compression. The article is ejected by continued upward movement of the lower die member 13. In a modification, Fig. 5, the dies are duplicated and both the auxiliary dies 35<a> and the cores 14 are resiliently mounted, the latter on a spring 45. The cores are positively moved by a lever 19 operated by a rod 17 from the upper sliding head 16 so as to dispose the material in the mould into annular form before the compressing operation as described in Specification 281,375. Hollow bodies with outside ribs and toothed projections can be formed in these devices and in one form coacting parts on the upper die and core form a V-depression in the top of the hollow body. In a still further modification of device for forming hollow cup-shaped bodies 130, Fig. 24, the core and upper dies are formed with flat portions to compress the material between them, the core 114 being resiliently mounted to cause the finished product to be uniformly compressed. The dies may be made in duplicate in one machine as previously described. Bodies having internal flanges and projections may be formed in this device by shaping the dies to produce the desired shapes. In a further modification, Fig. 32, the core is clamped by a screw 171 and plate 170 and is wedge-shaped, so that it gives when pressed axially.

Title: Stabilisation of monochlorbutenes
Inventor: NEWMAN FRANK CHRISTOPHER
IPC: C07C17/42
Filed: 1958-06-11
Abstract: A monochlorbutene, e.g. 3-chlorbutene-1 or 1-chlorbutene-2 or mixture thereof, is stabilised by incorporating therewith one or more organic sulphur compounds containing a divalent sulphur atom attached by one of its valencies to a carbon atom and by the second of its valencies either to a second carbon atom or to a hydrogen atom.  Specified organic sulphur compounds are mercaptans, e.g. methyl, ethyl, propyl, isopropyl, butyl, amyl, hexyl, dodecyl and benzyl mercaptans, sulphides such as dimethyl and diethyl sulphides, substituted mercaptans, e.g. thioglycollic acid and mercapto-benzthiazole, and thiodiphenylamine.  The organic sulphur compound functions as a polymerisation inhibitor especially in the presence of iron and may be added to the monochlorbutenes as such or in the form of a solution in an inert solvent such as xylene and concentrations of the organic sulphur compound of between 0,01 and 1% by weight based on the monochlorbutene are suitable.  In one embodiment the reaction product obtained by the substitutive chlorination of n-butene is fractionally distilled in the presence of one or more of the organic sulphur compounds to recover the monochlorbutenes as an overhead fraction and in this embodiment it is preferred to use a stabiliser having a boiling point the same as or lower than that of the monochlorbutene, e.g. isopropyl mercaptan, and to add the stabiliser to the feed to the distillation column so that it is taken along with the monochlorbutene fraction to storage.  A second organic sulphur compound having a boiling point higher than that of the monochlorbutene, e.g. mercapto-benzthiazole, thiodiphenylamine, dodecyl mercaptan, or benzyl mercaptan may also be added to the feed to the distillation column.  The monochlorbutene or monochlorobutene mixture may be obtained by the substitutive chloroination of n-butene or by the chlorination of butene-2 in the presence of butadiene. Reference is made for comparative purposes to the use of water, anisole, hydroquinone and t-butyl catechol as polymerisation inhibitors.  According to the Provisional Specification the sulphur compounds are defined as those having the general formula R-S-R1 wherein R is an alkyl, aryl, or aralkyl radical and R1 is hydrogen or an alkyl, aryl, or aralkyl radical, or where R and R1 together form part of a homocyclic or heterocyclic ring and functional derivatives of such compounds.
