Title: A photographic material for the production of photographic records with tone value correction
IPC: G03C1/46
Filed: 1957-06-20
Abstract: 845,217. Photographic silver halide materials. AGFA A. G. June 20, 1957 [June 26, 1956], No. 19467/57. Drawings to Specification. Class 98(2) Material for production of records with tone valve correction comprises a support having an inner layer of gamma valve of 0À5 to 0À9, and an outer layer thereover of gamma valve at least 1¢ times that of the inner layer and a speed of 1/20 to 1/80 of such inner layer. The two layers may be sensitive to the same or different regions of the spectrum, with both panchromatic they may be used for production of colour separation records of improved highlight reproduction, the image in the outer layer constituting a mask and such can be reduced if desired with Farmer's reducer without the lower image suffering. In a single example the emulsion disclosed in BIOS-Bericht 1355 page 35 green sensitised with 3, 31, 9-triethyl-5, 51-diphenyl oxacarbocyanine iodide is cast on an acetyl cellulose support and the emulsion of the Fiat Final Report 360, page 24 is cast thereover, and this material is exposed as in a process camera to a black and white original and treated in a specified developer to produce images of gamma valves 2À8 and 0À9 respectively, if exposure is made to a negative original tone valve correction in the shadows is achieved.

Abstract: 187,339. Buggs, H. J. July 21, 1921. Nozzles for producing whirling sprays; nozzles with regulable orifices.- A nozzle, more particularly for horticultural purposes, of the kind in which a whirling motion is imparted to the liquid before passing the jet, has one or more, preferably two, defecting vanes or surfaces formed bv edges K, Fig. 2, of openings G, Figs. 1 and 2, in a plate E arranged more or less to cover an equal number of passages F in the body A of the sprayer. The body A is threaded to carrv a. sleeve B, which carries the deflector plate E and also a centrally perforated cap C to form a whirl chamber D. By rotating the sleeve B, the openings F are more or less covered by the deflector plate, the amount of rotation being limited by a pin J engaging the edges of a slot in the sleeve B. Fig. 3 shows a modified form of deflector plate, in which the deflecting-surfaces K<1> are formed by straight portions of an opening G<1>. In a further modification, the sleeve is dispensed with, the whirl chamber being formed in the body of the nozzle, and the deflector plate is rotatable to the required extent in the body and retained in position by a screw, access to which is obtained by removing the jet.

Title: Production of aromatic nitriles
Inventor: KROEPER HUGO
IPC: C07C255/49
Filed: 1963-05-17
Abstract: A process for the production of aromatic nitriles comprises contacting (a) an aromatic hydrocarbon selected from the group consisting of alkyl-substituted benzenes with 1-3 alkyl groups of 1-4 C atoms, alkyl substituted naphthalenes with 1-2 alkyl groups of 1-4 C atoms and alkyl substituted diphenyls with 1-2 alkyl groups of 1-4 C atoms, (b) oxygen, and (c) ammonia at a temperature of from 300 DEG -500 DEG C. and at a pressure of from 400 mm Hg to 2 atmospheres with a catalyst consisting substantially of a member selected from the group consisting of vanadium oxide and a mixture of vanadium oxide and chromium oxide, the catalyst being supported on an alumina carrier made up of at least one member of the group consisting of g -, d -, c -, K- and X-alumina.  The reaction may be carried out for example by passing the gas mixture at the reaction temperature over the catalyst, then cooling the reaction gas and separating the nitriles by condensation, if desired by spraying in water. Several examples are given using xylene, toluene, diisopropylbenzene, 3,4-dimethyldiphenyl, 1 methyl naphthalene and mesitylene as starting materials.

Filed: 1960-06-03
Abstract: 913,823. Knitting. WIRKMASCHINENBAU APOLDA VEB. June 3, 1960, No. 19822/60. Addition to 891,132. Class 74 (2). To produce the plush fabric described in the parent Specification the ground yarn guides are mounted so that they extend horizontally leaving the plush yarn guides 7 alone extending substantially in line with the needles. The plush yarn guides are manipulated to wrap their yarns around the needles as the needles approach tuck height so that the further raising of the needles clears these yarns beneath the latches. The ground yarn guides are subsequently operated to feed their yarns to the needles which are then lowered to draw loops and cast off the plush yarns together with the previous course loops. Latch guards in the form of plates 14, 15 are associated with the ground yarn guides to ensure that the latches remain open during the feeding of the ground yarns.

Filed: 1937-07-23
Abstract: 497,105. Control of motors. DICKINSON, S., and EDWARDS, J. W. July 23, 1937, No. 20411. [Class 38 (iii)] [Also in Groups XL and XVI] Travelling to predetermined Limits.-In an apparatus for automatically folding a stack of sheets after a given number of sheets have been stacked, the folder is periodically operated by an electric motor 36 controlled as follows. As each sheet is fed to the stack, it is detected photo-electrically and causes a relay 5 to operate a relay 10 to rotate a ratchet wheel 17 one step. On the spindle 18 of this ratchet wheel there are four contact arms 19, 21, 24, 25 rotating over four rings of contacts 20, 22, 26, 27, some of which are blanks and some interconnected as shown. Switches 23, 23a are mounted on a common spindle and operated simultaneously to put in operation either the pair of contacts 20, 26 or the pair 22, 27. The first pair is used for stacking the sheets in threes, and the second pair for stacking the sheets in sixes. While the sheets are being stacked, the contact arms travel over blank contacts one step at a time, and, after the desired number of sheets has passed, the contact arm 19 or 21 comes over interconnected contacts 20 or 22, and current from the mains 6, 7 passes through these contacts to coil 30 through contacts 29. The armature 11 controlled by a spring 31 is then operated and rotates the ratchet wheel 17 a number of steps until the arm again reaches a blank contact, this operation being caused by the periodic opening and closing of the contacts 39. During this period, the contact arm 24 or 25 passes over the contacts 26 or 27, are interconnected, and current from the mains passes through these contacts, switch 23a, and contacts 39 to a coil 33, which closes contacts 35 to start the motor 36 driving the folding mechanism. When an eccentric i of this mechanism nearly completes a revolution, an adjustable pin 38 thereon opens the contacts 39 and the motor is stopped by a quick-acting brake 37, but not before the pin 38 has moved clear of the contacts 39 and the arm 24 or 25 has moved clear of the connected contacts 26 or 27.

One tappet 6 is connected by a link 5 to the catch rod 2 and by a link 9 to the fixed pivot 10. The other tappet 8 is connected by the link 7 to the hand-lever 1. The tappets fit together so as to be relatively slidable longitudinally, and at the upper ends, a yoke on one surrounds the other so that the link 9 guides both. The total travel of each tappet is the same. The weight of the parts acts to cause the tappets to fall in the interlocking box B if any part breaks; thereby the use of springs is avoided.
