Title: Improvements in or relating to the attachment of beading strips to articles
IPC: A45C13/00
Filed: 1936-03-21
Abstract: 472,178. Sewing-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., and RICKS, F. March 21, 1936, No. 8510. [Class 112] In a sewing-machine for sewing together parts of suit-cases or the like, a beading strip, comprising a cord covered with thin material which forms a flange on the strip, is introduced between the parts of the case so as to be sewn in place by the seam which sews the parts together. The work-guide comprises walls 2, 4 which guide the respective parts of the case and have apertures 8, 10 through which the needle 6 passes. The beading strip is fed through a guide member 3 carried by the wall 2, and this wall has a guiding groove 19 for the strip ; the part 21 of the wall 4 is inclined downwardly to allow 'the case part guided thereby to clear the member 3. In the form shown, the guide member 3 is pivoted to the wall 2, so that when the seam round the bottom of a case, for example, is being completed the member 3 can be turned up out of the way, the last part of the beading strip being sewn in without using the guide member. Preferably, however, the member 3 is made open at its wide end, so that it can be withdrawn laterally from the beading strip, and is either made of spring strip and sprung into a suitable aperture in the wall 2 or is held in an aperture in that wall by a spring catch, so as to be easily removed when required without disturbing the parts being sewn or the beading strip. Specifications 198,430, 330,521, [both in Class 112], 415,480, and 430,984 are referred to.

Abstract: 794,624. Valves. ESCHLER, M., [trading as ESCHLER URANIA-ACCESSOIRES, M.]. March 20, 1956 [March 21, 1955], No. 8595/56. Class 135. A valve comprises a cylindrical piston slidable in a bore in a casing and filled with a rubber or like closure member 6, which as the closure member moves from one limiting position to another alternately closes a port 7 with one of its ends and a passage 8 with the other end. The hollow piston 2 has an inwardly projecting ridge 5 which lies in a complementary groove in the closure member 6. The lower projecting part of the closure member 6 may have an upwardly curved lip which lies resiliently against the wall of the bore in the casing and prevents back flow of oil from the outlet port 10 to the inlet port 7. Fluid under pressure enters through the port 7, lifts the valve against the action of a spring 4 and presses the upper end of the closure member 6 against the passage 8 to close it. The fluid can then pass through port 10 to charge a dosing chamber. When the dosing chamber contains the desired quantity the flow of fluid through passage 7 is interrupted so that the spring 4 presses the piston 3 downwardly to close passage 7 and open passage 8 to permit the dosing chamber to discharge.

Filed: 1962-03-07
Abstract: 968,621. Fluid-pressure servomotor systems. WEATHERHEAD CO. March 7, 1962 [April 25, 1961], No. 8781/62. Heading G3P. [Also in Division F1] In an axial piston pump of the type in which the output is regulated by axial adjustment of the cylinder block whereby spill through each piston controlled inlet port is varied from a maximum to zero, the cylinder block is further axially adjustable whereby the effective area of the inlet ports is controlled. From the position shown in Fig. 1 movement of the cylinder block 62 to the left by the manually actuated shaft 117 causes increased spill from the inlet ports 85 during the pressure stroke; movement of the block 62 to the right causes the face 86 of the inlet port 85 to approach and finally coincide with the bottom dead centre position of the heads 71 of the pistons whereby the port 85 is progressively and finally totally closed by the pistons. In a modification the block is moved to regulate the output by spill by a servodevice actuated by outlet pressure and manually to regulate the output by controlling the effective inlet port area.

Title: Monophonic electronic musical instrument
IPC: G10H1/22
Filed: 1975-03-04
Abstract: 1506272 Electronic musical instruments HAMMOND CORP 4 March 1975 [4 March 1974] 8928/75 Heading G5J [Also in Division H3] In a monophonic instrument, such as a synthesizer, keys produce control signals on note busses which signals are encoded into a binary word which is stored in a memory, the stored word being used to gate from a tone generator a particular tone signal corresponding to a depressed key. In a complete system (Fig. 2) which is for instance associated with one keyboard 10 of a polyphonic instrument (Fig. 1, not shown), the key switches are coupled by diodes and preference circuits (Fig. 5, not shown) so that one line out of a group of 12 is marked to signal the note name of the higher key operated and one out of a further group of 6 to signal the octave of that note. The 12 and 6 lines respectively are applied to diode matrices which encode the signals to provide a four bit binary number representing the note and three bit number representing the octave; the two numbers are set into 7 bi-stable latches (Fig. 6, not shown). A generator 100 (Fig. 3, not shown) provides a set of top octave frequencies and the four bit number from the latches is decoded (Fig. 4, not shown) to gate an appropriate one of the frequencies to a set of dividers 170. The three bit number is decoded (Fig. 8, not shown) to gate the output from an appropriate one of the dividers to the amplifier and output circuits. The output of the latches is also applied to a D/A converter 230, which comprises seven different constant current generators (Fig. 8, not shown), which produces a voltage uniquely identifying the actuated key. This voltage may be applied by a log. function generator to a voltage controlled oscillator to provide tone signals (not described). The voltage is used to control other functions; the step in the voltage is used to generate a pulse at the start of each new note which may be used to trigger an envelope generator to provide for instance percussive tones. Tones played may also be prolonged after the key is released until the pulse signifies that a new key has been depressed. The direction of the voltage step may also be used to control pitch slide whereby the tone starts above or below the keyed note and slides down or up to it depending on whether it is higher or lower than the last note played. Voltage controlled filter and amplifier arrangements 210, 220 are also described (Figs. 9, 11, not shown). Full circuit details are given for all parts of the system. Specifications 1,506,271 and 1,506273 are referred to.

Abstract: 797,319. Automatic voltage control systems. BENDIX AVIATION CORPORATION. March 22, 1956 [March 31, 1955], No. 9016/56. Class 38 (4). [Also in Group XXXVI] A carbon pile regulator comprises two parallel, connected piles one having fewer and thicker carbon discs than the other, and means for simultaneously compressing the two piles. The resistance-elongation characteristics of the piles are arranged to intersect in the operating range of the regulator. Fig. 1 shows the lowresistance pile 8 of relatively thick discs and high-resistance pile 9 of thinner discs in a, housing 15 having cooling fins 16. An armature assembly 7 is associated with a spring diaphragm 35 and electromagnetic coil 6 and is adapted to compress the piles through contact plugs 31 and 33. The armature assembly is balanced. by counterweight 46 through spring member 47. The housing comprises cooling fins 16. Fig. 2 shows a regulator system for generator 51 embodying the regulator comprising the two piles 8 and 9 in series with the shunt field coil 54. Under high. speed no-load conditions only the high-resistance pile 9 is effective, the low-resistance pile 8 being open. As the total resistance of the regulator is decreased the low-resistance pile 8 enters into circuit, and at full load, low speed is carrying most of the load. Under conditions of in-. creasing resistance when the low-resistance pile opens, the high-resistance pile still provides a shunt resistance so that any tendency for arcs across the low resistance pile is decreased.
