Title: A process and apparatus for making dough rolls
IPC: A21C3/06
Filed: 1944-02-08
Abstract: 594,695. Moulding dough rolls. BUECHEK, J., and McMURTRIE, U. Feb. 8, 1944. No. 2312. [Class 87 (ii)] [Also in Groups XXX and XXXVII] In making a dough roll by rolling up a continuously advancing sheet of dough, oil is applied to the whole width of the sheet except for the longitudinal edge portion which is to be last rolled, and water is applied to the said longitudinal edge portion to form a roll-sealing surface, the oiled edge being progressively turned upwardly and then progressively turned inwardly to roll up the sheet until the watered edge is finally turned upon the resulting roll, the second turning being accompanied by continuous application of uniform pressure to the roll as it is formed and regardless of roll diameter. The baker pushes a hand-formed flat sheet of dough on to a conveyer belt 23 leading to a vertically-reciprocating beater 25 which flattens out the dough. The flattened dough piece then passes between two pairs of rollers 36, 37 and 38, 39, and drops on to an endless conveyer 70 which takes it forward to a rotating roller 127 which forms the dough sheet into a roll. As the roll is being formed another rotating roller 128, resiliently mounted to yield vertically and adjustably counterweighted at 129a, presses on the roll and controls the tightness of the latter. As the dough travels from left to right along the machine, (a) it is dusted with flour at 48, (b) it is sprayed with oil from spray heads 77 and water from spray head 78, and (c) sugar, cinnamon, nuts, raisins, cream &c. are applied to the oiled surface from one or more hoppers 92 (see Group XXX). When the roll has been formed it travels to the right, passes between two vertically disposed belts 132, 137, drops into a vertically disposed cylinder 148, and is cut into lengths by the bars 150 of a cutting wheel 149. This wheel is turned intermittently by pawl-and-ratchet mechanism 151 operated by a solenoid 155 which is intermittently energised by a make-and-break switch (see Group XXXVII) which may be adjusted to vary the length cut off the roll.

Title: Improvements in or relating to traction arrangements for agricultural implements
IPC: A01B63/24
Filed: 1937-01-26
Abstract: 494,750. Implements for working land. CHARRUES MELOTTE. Jan. 26,1937, No. 2336. Void. Convention date, Feb. 15, 1936. [Class 6 (i)] The draw-bar or guide-beam of a reversible agricultural implement is adapted to be fixed in any one of a number of inclined positions with respect to the direction of travel by means of a control lever pivoted on it and engaging in a notch in one of two ears adjustably fixed on a perforated sector. This sector 6 is shown mounted on a crossmember 4 pivotally mounted on longitudinal members 5. The notched ears 9 are adjustably secured by pins 8 and the spring-controlled control lever 14 is pivoted on projections 17 on the upper part 12 of the double draw-bar or guide-beam 11 and passes through slots in it. At the end of a furrow, the draw-bar 11 is moved to bring the lever 14 into engagement with the other notched ear 9, to offset the plough in the opposite direction relative to the tractor to which it is connected. The drawbar may be unlocked manually or automatically. For unlocking it automatically as the plough is raised, a cam member 20 on the axle 19 may have a projection 21 to engage a projection 22 on a bar 23 connected to the lever 14, so as to actuate the lever 14 as the axle 19 is rotated. Relative adjustment of the projections 21, 22 may be effected by a screw 25.

Title: Process for manufacturing multilayer film circuits
IPC: H05K3/46
Filed: 1965-01-19
Abstract: <PICT:1092071/C6-C7/1> In the manufacture of cryotrons involving the formation of successive films of conductive and insulating material selected areas of the conductive films are removed to form parts of the cryotron, and holes are formed in the insulating films through which electrical contact between adjacent films is established. The flip-flop shown schematically in Fig. 1 may be formed on a substrate of glass or plastic by subjecting it to a glow discharge in oxygen or argon and then vapour depositing lead to form a ground plate.  This is reduced to the required form by standard positive photo-resist masking and etching techniques.  After removing the photo-resist a negative photo-resist material is applied and apertures formed in it by similar techniques.  A tin layer is then deposited over this layer to contact the ground plane through the holes.  The layer is then reduced by photo-resist masking and etching techniques to leave the gates 34, 36, 46, 48 and the tin in the aperture.  After removing the photo-resist a further layer of photo-resist is applied and apertured and a second layer of lead vapour deposited and reduced by etching using photo-resist masking.  Finally the assembly is covered with a layer of insulating photo-resist. The number of processing steps may be reduced by using the same photo-resist layer for the formation of masks for each metal shaping and subsequent aperture forming process. If required the order in which the layers are deposited may be reversed and the metals deposited by sputtering.

Title: Pilot controlled gain regulator for communication circuits
IPC: H04B3/10
Filed: 1953-01-28
Abstract: 725,947. Automatic volume control. AUTOMATIC ELECTRIC LABORATORIES, Inc. Jan. 28, 1953 [Feb. 4, 1952], No. 2466/53. Class 40 (4). A pilot-controlled gain regulating device for a line transmission system comprises a bridge circuit including a variable impedance element and a frequency-selective network in one arm thereof, wherein the input is applied across one diagonal and the output, which includes a second variable impedance element, is taken from across the other. The arrangement, which is designed to correct for the difference in the rate of change of transmission constants with frequency for different weather conditions, compensates for over attenuation of lower frequencies by equaliser 3, Fig. 1, during dry conditions. The bridge comprises the two halves of secondary winding 7 of the hybrid transformer, a resistor 9 of approximately 300# and a circuit including a tungsten filament lamp 17 shunted by a 300# resistor 19 and a large blocking condenser 20, and a tuned network comprising condensers 23, 27 and resistors 25, 29. The pilot frequency which is at the upper end of the band is selected by a filter 45, rectified in a rectifier 49 and applied to the grid of a valve 55 to control the current in its anode circuit which includes the variable resistance lamps 17 and 43. The network which is tuned to the higher frequencies reduces the level of high frequencies at dry conditions and lamp 43 which is shunted across the line effects gain control. Alternative types of variable impedance element may be used in which the resistive changes are +ve orve and the bridge would be modified accordingly.
