Title: Improvements in dough moulding machines
IPC: A21C9/00
Filed: 1936-01-24
Abstract: 469,454. Moulding dough. HUMIDOR, Ltd., and MAAS, L. J. P. Jan. 24, 1936, No. 2345. [Class 87 (ii)] In a dough-moulding machine a flattened piece of dough is fed onto a table or carrier and folded on itself by relative reciprocation between the feeding means and the table, a flap pivoted on the table being provided to receive a portion of the dough and to fold it over. A dough lump 8 in the hopper 5 is fed by rolls 6 between pairs of rollers 1, 3 which flatten it. The flattened piece falls on to a reciprocating carrier 28 which comprises an endless belt stretched on rollers 29, and is carried by a pivoted lever 34 which is oscillated by a cam 37 and spring 38. A wooden flap 39 is pivoted on a shaft 40 which is connected through gearing 41, 42 with a lever 44 whose end runs in a cam slot 46 in an adjustable plate 47<1>. The front end 27 of the dough is deposited on the flap 39 and then on the carrier 28 as it reciprocates. As the roller 45 enters the part 46<1> of the slot 46 the flap is caused to swing over and fold the dough on to the carrier 28. When the carrier moves in the reverse direction the flap is moved back and the last portion of dough is deposited on the first as shown in Fig. 9. The cam slot 46 is so shaped that the flap 39 slightly compresses the dough when it swings over. The ends of the rollers 29 are provided with clutch members 49 which engage driven members 50 in the extreme position of movement so that the belt 28 is started and delivers the folded dough piece for further treatment. The flap 39 may be provided with spikes 66 to grip the dough. A pocket wheel 59 may be provided to feed lumps of dough to the hopper 5 at the desired moment. In order to produce a folded piece with inclined edges the axes of the rolls 3 and the shaft 40 may be inclined to the direction of movement of the carrier 28. Alternatively the rolls 3 may be conical as in Fig. 12. In a further modification the carrier 28 may be inclined to the horizontal in a transverse direction.

Title: Improvements in or relating to electron discharge devices of the beam storage type
IPC: H01J31/60
Filed: 1956-01-27
Abstract: 785,578. Electric digital-data-storage apparatus. WESTERN ELECTRIC CO., Inc. Jan. 27, 1956 [Feb. 4, 1955], No. 2743/56. Class 106 (1). [Also in Group XL (a)] The dielectric target of a storage tube has the back plate and the barrier or field equalizing grid electrode connected respectively to inner and outer conductors which are electromagnetically coupled together as in a coiled coaxial line. In Fig. 1, the beam from a focusing and deflecting system 11-17 scans a dielectric sheet 23 which is enclosed with the back plate 22 in a shielding member 26 to which the barrier grid 24 is attached. The back plate is raised temporarily to a positive potential by a writing signal, the incident beam charging the elemental area negatively until it reaches equilibrium at the potential of the barrier grid. The writing circuit is applied to the inner and outer conductors 29, 30 of a coaxial line 28, the inner conductor 29 being connected to back plate 22 and the outer conductor 30 which is of thick brass to reduce resistance, is connected to the barrier grid 24. During writing, the flow of currents in the coiled portion 32 are in opposite directions and it behaves as a non- inductive winding. During reading, the negatively charged elemental areas are discharged by secondary emission greater than unity and current flows in both conductors in the same direction producing a signal voltage across the coiled portion and the load 34 for feeding to amplifier 35. The writing signal induces little or no signal in the reading amplifier. A magnetic or ferrite core may be included in the coiled conductors 32. A cancelling pulse generator operated by the writing source may feed to the amplifier 35 to correct the residual error due to the unbalance of current flow in the two conductors of the coaxial line. The storage target may be a back plate carrying small spots or islands of dielectric material and the coil portion of the coaxial line may be connected by a transformer coupling to the output amplifier (Fig. 4, not shown). Specification 701,010, [Group XL (a)], is referred to.

Title: Process and apparatus for the regular supply of dough to a dough-processing machine
IPC: A21C3/00
Filed: 1962-01-25
Abstract: 998,740. Dough dividing machines. ATELIERS DE CONSTRUCTION GUILLAUME OOMS S.A. Jan. 25, 1962 [Dec. 6, 1961], No. 2947/62. Heading B5A. [Also in Division B8] A large batch of dough is conveyed by a first conveying means to a dividing means where it is divided into a number of relatively small batches of dough which are transferred on to a second conveying means and conveyed to a dough processing machine. A mass of dough 16 is poured on a conveyer 2, which is temporarily accelerated to bring the mass against the dividing device 3, which detaches portions of dough 17 from the mass 16 and deposits them at an adjustable rate on a conveyer 4. The portions 17 are then fed one at a time to a continuously operating processing machine 15. The conveyers 2, 4 and the dividing device 3 are driven from motors 5, 11, 8 respectively, all controlled by a switching gear 14 which also acts as a safety device, instantaneously stopping the machine when the feed supply is in excess. The dividing device consists of a shaft 10 carrying discs 18 . . . 21 all joined together by a cross-bar 22 acting as the dividing knife. An extra conveyer located so as to overhang the forward end of conveyer 4, brings back dough refuse from the processing machine, dropping it on conveyer 4. Advantageously the conveyer 2 has mobile walls consisting of two endless belts driven either by the dough itself or mechanically. A spot-light and a photoelectric cell can be placed along the axis X-X, so that when the conveyer 2 is no longer supplied with dough the light will reach the photo-electric cell causing automatic acceleration of the conveyer 2.

Patent GB-717751-A (GB)
Title: Production of lubricating oil
IPC: C10M101/02
Filed: 1951-02-07
Abstract: Lubricating oil is made by chlorinating petroleum wax to a chlorine content of more than 20 per cent and dehydrochlorinating the product by contact with a silica-alumina catalyst at above 550 DEG  F. although not high enough to cause cracking, preferably about 575-725 DEG  F., for a time sufficient substantially completely to remove the chlorine from the chlorinated wax and to yield a relatively saturated oil.  A "relatively saturated oil" is one in which the molar unsaturation does not exceed 20 per cent.  The oils have high viscosity indices, lower pour points and low bromine numbers. Dewaxing steps are not required.  Waxes of lower molecular weight, e.g. about 350 should be chlorinated to a chlorine content of at least 25 and preferably 25-30 per cent whilst higher molecular weight waxes, e.g. 450-700, should be chlorinated to a chlorine content of at least 20 and preferably about 25 per cent.  Chlorination temperatures of about 100-250 DEG  F. are mentioned but if the wax is substantially free of dissolved oxygen and the chlorination is effected in the absence of air, temperatures up to 300 DEG  F. may be used.  Catalysts mentioned are those used in catalytic cracking, Florida clay or Montmorillonite clay acid treated natural clays, e.g. "Filtrol" (Registered Trade Mark).  A dehydrochlorination time of approximately half an hour is given for about 600 DEG  F. and approximately 10 minutes at 725 DEG  F.  At least 5 per cent of catalyst should be used, usually 8-13 per cent.  In examples (1) slack wax is chlorinated to 26.9 per cent and the product treated with 20 per cent of "Filtrol" at 550 DEG  F. for 5 hours; (2) slack wax is chlorinated to 26.9 per cent and the product treated with 25 per cent of "Filtrol" at 600 DEG  F. for about 3 1/2 hours; (3) white refined paraffin wax of M.W. 480-500 is chlorinated to a content of 20 per cent and the product treated continuously and batchwise with clay at 600 DEG  F. shorter reaction times being required in continuous operation; (4) slack wax is chlorinated to a content of 25 per cent and the product treated with 5 per cent of "Filtrol" at 740 DEG  F. for 20 minutes and in a comparative experiment slack wax of M.W. 490 is chlorinated to 9 per cent and the product treated with 15 per cent of "Filtrol" at 640 DEG  F. for about 3 hours, and dewaxed. Physical characteristics are given of all the product oils of the examples.  Specification 694,488 is referred to.
