IPC: D04B39/00
Filed: 1942-08-11
Abstract: 554,036. Knitting. SMITH, H. N., and SMITH, E. E. Sept. 12, 1941, Nos. 10242/41, 14895/41, 3858/42 and 11254/42. [Class 74 (ii);] A knitting machine having looping devices 4 each arranged to form a loop selectively in either direction successively through each of a series of loops held upon guard members 1 is adapted for fashioning or patterning by periodically changing the number of loops awaiting cooperation with the devices 4. The addition to or subtraction from the number of loops ds under the control of a Jacquard or other patterning mechanism. In one form of machine, two rows of pivoted guard members are provided, mounted in guide grooves in inclined beds and each member having a channel shaped end 2. An additional guard member may be introduced, or a guard member may be withdrawn, for fashioning, and two or more loops may be placed upon a single guard member. To facilitate the formation of the knitted loop, a member 40 is provided for each guard member 1 to accept temporarily the newly formed loop and to cast the old loop off the member 1, and to asssist in transferring the loops back to the guard members 1, plates 93 are provided to push outwardly the fabric already formed. A looping device 4 and a thread guide 5 co-operate with the members 1 in each bed and are mounted upon carriages movable step-by-step along the series of members 1. Jacquard or other patterning mechanism is also provided to determine the direction of rotation of each looping device 4, so that the direction in which a loop is drawn through a loop around any guard member 1 is controlled for patterning by purl knitting. To allow two or more loops to be drawn through a loop around a guard member, e.g., during widening, the bed containing the guard members may be shogged in the direction of the movement of the carriage supporting the looping device. For narrowing purposes the beds containing the temporary accepting members 40 may be shogged. The machine may be arranged to knit at one time either two separate pieces of fabric, or one flat piece by knitting first on one bed of members 1 with a particular thread guide, and then changing over the positions of the two thread guides so that the same thread is supplied to both beds, or tubular fabric. The positioning of the yarn guide is determined by patterning mechanism. Specifications 536,489 and 551,370 are referred to.

Abstract: 1424174 Cheese making CLAUDEL SA 14 March 1974 [16 April 1973 16 Aug 1973] 11326/74 Heading A2B Cheese is made by subjecting milk to ultrafiltration to obtain a liquid product containing all or some of the milk proteins, coagulating the said liquid product by heat, innoculating with suitable ferments and adding rennet, invertical chamber where it is allowed to coagulate until a coherent mass is obtained, displacing the coherent mass upwardly by uniform pressure over the base and after the coagulum has emerged to a predetermined height, cutting off unit slabs each of which will form a cheese. The pressure may be provided by a piston at the base of the vertical chamber. The ultrafiltered milk may be kept in a tank from which it may be fed continuously into the vertical chamber, the filling of the chamber from above and the descent of the piston taking place simultaneously. When skimmed milk is treated by ultrafiltration edible fats such as animal fats (cream of milk or oil of butter) or vegetable fats (peanut oil) may be added prior to the heat treatment. The liquid product may have a non-fat solids content of not more than 18% by weight. The cut slabs of coagulum may be deposited into moulds. If desired, the unit slabs need not be separated but may be left to form a stack. If desired the cut slabs may be fragmented and the fragmented slabs introduced into a mould. The process may be carried out in the apparatus described and claimed in Specification 1424175.

Title: Electronic amplifier
IPC: G05D3/18
Filed: 1949-04-29
Abstract: 684,955. Valve amplifying circuits. BENDIX AVIATION CORPORATION. April 29, 1949 [July 2, 1948], No. 11482/49. Class 40 (vi). In an amplifier providing an output responsive to the phase sense and amplitude of the applied A.C. signal, the input is fed in parallel to the grids of two cathode followers energized in push-pull with A.C. of the same frequency. The cathode followers are connected to two negatively biased valves so that the signal causes one or other to conduct in response to the phase of the fundamental frequency of the input. The system is particularly applicable to the amplification of small error signals which may contain undesired harmonic components that may affect the operation of a servomotor system. The signal from source 11, amplified in valves 13, 14 is fed in parallel to cathode followers 17, 18 energized with A.C. from transformer 32. According to the phase of the input, relative to the reference A.C. source 33, one or other of the cathodes of valves 17, 18 goes positive causing normally non-conducting valve 53 or 54 to pass current. The flow of anode current through the magnetic amplifier 12 results in A.C. appearing at the output, the phase depending on which of the valves 53, 54 is conducting, while the amplitude varies with the current flow in the valve. The leads 72 are connected to a two-phase motor, the second phase being energized from the supply.
