Abstract: 1,237,928. Degreasing leather, &c. FERENTZI & KESSLER. 18 Nov., 1968, No. 54637/68. Heading DIL. [Also in Division C6] Sheep skins, or other skins, hides or leather, preferably sewn together as in Specification 1,237,929, are wet treated by being passed between a pair of endless belts 17, 18 the juxtaposed runs of which pass between pairs of rollers 3 and 6, 4 and 7, 5 and 8 immersed in the treating liquid in a bath 1, each pair of rollers being held together under pressure. The liquid may be a degreasing solvent, a tanning liquid, or other liquid used for steeping, washing, currying, pickling or dyeing. The liquid enters the bath via inlet pipe 21 and is removed by pipe 22; flowing counter to the direction of travel of the skins, so that the skins encounter fresh liquid just prior to leaving the bath. A pair of rollers 11, 12 urged together under a higher pressure than the immersed rollers squeeze out the liquid from the issuing skins. A pair of inlet rollers 9, 10 is also provided. The belts 17, 18 are preferably porous.

Abstract: 1,257,475. Snow clearing apparatus. J. HARTLIEB. 22 Nov., 1968 [22 Nov., 1967; 5 Feb., 1968], No. 55608/68. Heading E1G. In vehicle-mounted snow-clearing apparatus for roads, railways &c. some of the snow 43a, Fig. 7, in front of plough blade 40 is picked up by a rotor 49 and introduced into a pumped circulation system comprising a container 23 for salt or like solution and a heated melting and mixing chamber 44-8 having an overflow 47 to the ground underneath, whereby the remaining snow 67 in front of the plough 40 is flooded with a hot solution of salt and melted snow. The apparatus is bolted on the front of a vehicle and comprises one or more transverse or longitudinal boiler cylinders 14 heated by burners. The Specification discloses numerous diagrammatically illustrated modifications. Figs. 1, 2 and 4 (not shown) illustrate three different arrangements of longitudinal boilers (60, 60a), and different-height snow baffles (70) for directing snow into several melting chambers. In Fig. 7 the water in chamber 8 is heated in part by gases escaping from a corrugated heat exchanger 27 on a perforated transverse boiler cylinder 14. The salt container 23 incorporates a fine mesh screen 39 below which is an inlet 32 for pumped water. The chamber 44-8 has outlets leading to the pump and to various fixed sprays (e.g. for clearing under parked vehicles) and flexible hoses. The rotor 49, Fig. 8, comprises preferably two drums each composed of cutting discs 73 and angularly displaced paddle wheels 72 having semi-cylindrical pick-up vanes. The drum(s) cooperate with a deflector 121, an adjustable-height cutting blade 2, and a regulating flap 50, the assembly being retractably mounted on inclined guide rails 71. Snow passing forward of the flap 50 is laterally expelled through an angularly adjustable outlet 51-52, or may be ducted rearwardly for discharge into the vehicle itself or a trailer. The oblique plough 40, Fig. 5, may be vertically spring-loaded and may carry extensions 106 and spray nozzles 38. Additional retractable ploughs 55 may be provided in front of the rotor, together with fixed baffles 24, hot air blowers 37, and suction nozzles 110.

Abstract: 1,264,069. Character recognition. GENERAL ELECTRIC CO. 23 July, 1970 [12 Aug., 1969], No. 35653/70. Heading G4R. Apparatus for recognizing magnetic ink symbols comprises means for D.C. magnetizing the symbols and means for moving each symbol relative to a transducer, integrator means coupled to the transducer providing a waveshape having a variable voltage amplitude representing the total quantity of ink of the symbol, and means comparing successive average signal levels. A single-slit magnetic head has an inductance coil which, together with an amplifier having a negative feedback resistor, forms the integrator. The integrated waveshape signal is passed down a tapped delay line, a correlation network responding to tap outputs to identify the symbol. A first and last tap are also connected to the negative input of a summing amplifier and intervening taps are connected to the positive input, via resistors, to provide a signal representing the average level of the wave-shape signal. Another summing amplifier has its positive input connected to the penultimate tap and its negative input connected to other taps, via resistors, to detect registration of the waveshape signal in the delay line. When the outputs of these two summing amplifiers both exceed respective thresholds, a timing circuit starts. A " sample " signal gates the output of the correlation network into latches. A factor recognition system includes summing amplifiers each having its positive and negative inputs connected via resistors to taps on the delay line, the summing amplifier outputs being thresholded and gated at a " test time " to reset selected (initially-set) " test " bi-stables according to features recognized. The " test " bistables provide reset signals for some of the latches mentioned to delete results from the correlation network which are incompatible with the features recognized, and also the " test " bi-stable states are compared appropriately with states of some of the latches to produce a symbol reject signal at a " read time " if incompatible. A symbol reject signal is also produced if other than one of the latches is set, and also if the average level signal (see above) for the symbol is less than half the similar signal for the preceding symbol. At "read time " the latch states are gated to an output if the symbol reject signal is absent. If one of the feature detecting thresholders (see above) produces an output when a photo-cell does not detect a document at the reading station, a " noise indicator " lamp is lit to indicate to the operator that there are magnetic particles on the roller used for driving the document, these particles being sensed by the read head.

Abstract: 1302391 Cheese M A LEPRINO JNR and J G LEPRINO [trading as J & M PROPERTIES] 30 April 1970 20896/70 Heading A2B A process for making mozzarella or pizza cheese comprises cutting, stirring and cooking a mixture of curd and whey, separating the whey from the curd particles when the particles have an internal pH of 6-6.5, and soaking the separated cooked curd in water at 90-130‹F and at a pH of 5-7 until most of the lactose has been extracted and the curd particles have an internal pH of 5-5.5. The curd particles after separation from the water e.g. by a rotating screen, may be subjected to mixing, stretching, compressing, moulding, brining, curing and packing steps. The mixture of curd and whey may be obtained by treating milk with S. lactis, S. thermophilus, L. bulgaricus rennet and pepsin. In the apparatus shown the curd having a pH of 5-5.5 is separated from most of the water by rotating screen 22 and passed through section 24a to auger unit 25 where it is mixed wth the remaining water heated by steam. In section 44 the curd is subjected to back pressure due to the relatively small annular exit opening 48 between rotary or stationary plate 47 and the casing of section 44. The curd is then passed to moulding station 26.
