Filed: 1959-08-27
Abstract: 932,738. Binaural reproduction. BLAUPUNKT-WERKE G.m.b.H. Aug. 27, 1959 [Sept. 13, 1958], No. 29282/59. Class 40 (4). [Also in Group XL (c)] The cabinet of sound-reproduction apparatus for the selective reproduction of monaural or stereophonic signals has in respective side walls 4, 5 wide range loud-speakers 2, 3 and, in each of the two regions of the front wall 8 adjacent the side walls, a treble loud-speaker 6, 7 connected to the wide range loud-speaker in the adjacent side wall. For monaural reproduction the four loud-speakers are connected to amplifier 9 while for stereophonic reproduction loud-speakers 2, 6 are connected to amplifier 9 and loud-speakers 3, 7 are connected to amplifier 10. The connections are altered by a switch 11 connected to the amplifier outputs. A change-over switch (not shown) may be inserted at input of amplifier 10 in order to adapt the amplifier input conditions to monaural or stereophonic signals as required.
Patent GB-1138169-A (GB)
Title: High speed printers
IPC: C10L3/04
Filed: 1966-06-29
Abstract: 1,138,169. Electrically controlled printers. ANELEX CORP. 29 June, 1966 [22 July, 1965], No. 29286/66. Heading G4H. [Also in Division H3] In a high-speed printer of the kind in which the print hammers 17 are actuated from a power supply source 41 via capacitors 39, the charge on which falls when the hammers are actuated at a high rate in printing a line, there are sensing means to detect when the potential of the supply falls below a predetermined value to prevent the printing of the next line for a predetermined period. The type rotates with roll 1, a shaft encoder generating a series of codes identifying the characters as they come into printing position. Character codes are read out of memory 35 in succession by timing means 33 and compared at 31 with each of the successive character codes from encoder 7. Upon agreement the corresponding hammer magnet 21 is actuated, the current being supplied over line 23 from the bank of capacitors 39 charged by the source 41. The more rapidly the hammers are actuated the more discharged the capacitors become. The available potential is applied to a divider comprising Zener diode 61 and resistor 63. The diode subtracts a constant voltage, and the remainder is applied via diode 71 to resistor 73, and via diode 65 to capacitor 69, shunted by resistor 67. When the charge in capacitors 39 falls, the voltage across resistor 73 falls immediately, while that across resistor 67 is held up by capacitor 69. A difference amplifier 75 receiving these two voltages sets a monostable 77 if the difference is large enough, applying a positive signal of the predetermined period to the a input of NOR gate 79, which accordingly provides no advance signal for the paper feed mechanism. Interlock circuits, connected via switch 83, prevent the next line being printed until the paper has been moved. A form control device 55 controlled, for example, by a photoelectrically sensed punched tape, governs the extent of movement of the paper, to cause the next line to be printed in the next position.

Title: Improvements in or relating to the shaping of shoe uppers to lasts
IPC: A43D21/12
Filed: 1932-10-20
Abstract: 410,803. Boots and shoes. UNITED SHOE MACHINERY CORPORATION, 140, Federal Street, Boston, U.S.A.-(Assignees of Pym, C. F.; Beverly, Massachusetts, U.S.A.) Oct. 20, 1932, No. 29327. Convention date, Oct. 26,1931. [Classes 17 (i) and 17 (ii).] Lasting.-Especially for shoes wherein the margin of the upper is secured to the margin of the insole by adhesive, the upper is shaped to the shape of the last and the marginal portion of the upper laid inwardly over the insole, this marginal portion being thereafter wiped inwardly from the edge of the shoe bottom by a heated ironing tool. A shoe previously lasted at the toe and heel ends is positioned by a last pin 28 secured in a block 24 carried by a rubber apron 20 extending along the sides of the last and secured to plates 22 shaped to conform with the sides of the last bottom. The last is forced downwardly by a member 30 while clamping members 27 are swung inwardly to maintain the block upright, and the overlaying members are moved inwardly towards the shoe. The upper is thus wiped heightwise of the last to shape it to the last, distortion of the heel end being prevented by members 29 of rubber or leather, engaging the upper at this portion carried by a resilient plate 31 secured to the block. Adhesive may then be applied to the margins of the upper materials, or adhesive previously applied cut with a solvent, and the last further depressed below the level of the plates 22, which are then moved inwardly to lay the margin of the upper over the insole. A spring-pressed plunger 35 is then allowed to raise the last by slight lift of the member 30 to press the margin of the overlaid upper hard against the members 22. After a short period, to allow the cement to set sufficiently to hold the upper against displacement, the work is removed and positioned in a second machine having electrically-heated ironing members 32 shaped to the contour of the last bottom, the last being forced against these members while they are moved towards each other. If cement with a rubber base is used, it may be first softened and then vulcanized by the hot members. If a slow setting cement is used, a few tacks may be inserted at the edge of the upper while this is under the pressure of the members 22, which tacks may be engaged by the members 32 further to tighten the upper.

Title: Improvements in and relating to carburettors

Filed: 1931-10-24
Abstract: 382,065. Spray carburetters. BOSCH AKT.-GES., R., 4, Militarstrasse, Stuttgart, Germany. Oct. 24, 1931, No. 29536. Convention date, Nov. 8, 1930. [Class 7 (iii).] A spraying tube a extends transversely across the mixing chamber 10, is traversed by an adjustable plunger tube e, and dips into fuel in an auxiliary chamber 12, Fig. 6, which communicates with the float chamber 11. The space between the spraying and plunger tubes is divided by an enlargement h on the plunger tube into a spraying passage k with outlet orifice d, and a passage m which communicates with the interior of the plunger tube by an aperture n, Fig. 1, and with the slow-running outlet 14 by a conduit 15 and aperture o. The spraying tube is provided with an aperture p which places the passage m in communication with the choke tube, the extent of the communication being variable by adjustment of the tube e and the enlargement h thereon. At light loads, with throttle nearly closed, the suction is intense in conduit 15 and would result in too great a fuel supply through aperture n were it not for the aperture p. At intermediate loads spraying first occurs at 14, and then with increased throttle opening a reverse flow of air occurs from 14 towards p. At full loads the intense lowering of pressure at the spraying orifice d, Fig. 6, causes auxiliary air to be drawn from the passage m past the enlargement h to mix with the fuel and prevent excessive flow.

The inner end has a sealing-ring, e.g. 16, elastically retained in a groove 18 in the journal so as to rotate therewith which cooperates with an elastic sealing-ring, e.g. 14, in a groove of the sleeve 4, or with an annular recess in the sleeve to provide sealing-gaps and contact seals at various points. Various configurations of the two sealing-rings are described. Particularly when the roll is a single roll mounted by trunnions at its ends, the cover 9 is replaced by a similar arrangement of sealing-rings. A resilient cot 8 is provided.
