IPC: G05D16/10
Filed: 1951-05-24
Abstract: 733,335. Fluid-pressure servomotors; valves. SPERRY GYROSCOPE CO., Ltd. May 16, 1952 [May 24, 1951], No. 12171/51. Class 135. A pressure-regulating valve for controlling the supply of liquid to hydraulic apparatus such as a servomotor system for controlling the attitude and direction of flight of an aircraft and functioning to provide a gradual rise of pressure to the working value when the supply is initiated comprises differential pistons 2, 8 of which the piston 2 controls an inlet 1 from the source of pressure liquid and the space between the pistons is subject to the controlled pressure whereby an upward or valve-closing thrust is produced which is opposed by a spring 14. The outlet conduit 3 from the valve passes to a piston valve 4, 6 controlled by a variable-torque clutch 17 and arranged to connect a conduit 5 leading to the hydraulic apparatus with either the conduit 3 or an exhaust 7. Pressure in the conduit 5 communicates through a passage 10 containing a restriction 11 with a piston 13 serving as an abutment for the spring 14 whereby a gradual increase in the spring- loading on the pistons 2, 8 is obtained after the valve 4, 6 has been set to interconnect the conduits 3, 5.

Title: Arrangement for introducing voltages into alternating current circuits
IPC: G05F1/253
Filed: 1928-04-26
Abstract: 290,278. Siemens - Schuckertwerke Akt.-Ges., (Assignees of Siemens-Schuckertwerke Ges.). May 12, 1927, [Convention date]. Bcosting by dynamo-electric machines; systems depending on two or more machines; neutralizing self-induction.-Two frequency converters coupled together and connected in series are used to inject a desired voltage into an a.c. circuit. A voltage proportional to the current in a system 1, Fig. 1, is injected therein by a pair of rotary frequency changers 2, 3 having their commutators connected together through a transformer 5, one of the machines having a compensating winding 6. An induction motor 4 supplies the no-load driving losses. In the system shown in Fig. 2, the frequency changer 2 is used to influence either the induction L or resistance R of a circuit, and the machine 3 is excited by the potential drop across an ohmic resistance r. The phase of the injected voltage is determined by the setting of the commutator brushes or the adjustment of the coupling between the machines, and its value by the excitation conditions and by the coupling transformer, which may be a regulating transformer. Self-induction may be neutralized, notwithstanding variations in circuit frequency, by using a circuit transformer to excite one of the machines, and this arrangement may be applied in the exciting circuit of a cascaded commutator machine.

Filed: 1928-04-26
Abstract: 320,914. Hamilton, M., and Sutton, G. J. April 26, 1928. Pleating.-In a device for forming pleats in material in the direction in which relative movement occurs between the device and the material, a pair of grooved co-operating surfaces form upstanding pleats which are guided into inclined slots for overturning said pleats after which they may be pressed flat. One form of the invention is shown in Fig. 2 in section and in Fig. 3 in plan as seen from below. The device comprises a part 11 over which the fabric passes and a part 10 with an extension 17 under which the fabric passes. To the part 11 is attached a roll 13 and to the part 10 a roll 12, the two rolls having complementary interengaging surfaces for forming the pleats. A sole plate 23 terminates in bent-up fingers, which project between recesses in the roll 12 and serves to lead the pleats into appropriate slots 21 in a guide member 19. A plate 20 with inclined slots 21 turn the pleats over and they may be flattened by an iron. The iron is mounted on a plate 15 and is retained in position thereon by shaped gripping parts 29 of the part 10. The guide member 19 and plate 20 may be replaced by a single unit. In operation the device is either moved longitudinally of the cloth or the latter is pulled through the device. The guiding and turning over device may be arranged with slots inclined in any direction and in one form shown in Fig. 9 one set of slots 35 is arranged oppositely to another set 35<1> on the same turning over member 32. When used in the production of box pleats this results in separating oppositely set pleats.

Title: Improvements in or relating to pulse generator circuits
IPC: H02M7/537
Filed: 1958-04-21
Abstract: 837,509. Magnetic amplifiers. WESTING- HOUSE ELECTRIC CORPORATION. April 21, 1958 [April 29, 1957], No. 12541/58. Class 40 (9). The output from a magnetic amplifier to a load is obtained from a direct-current power source, the circuit of which is gated by transistors so as to provide a train of pulses, the duration of each pulse being determined by the amplifier control signal. As shown in Fig. 1, a direct current source 51 and a load 59 are connected to the amplifier load windings 13, 23, and each load winding is energized in turn by completion of a current path through a transistor 60, 70, the transistors being made conductive alternately by alternating pulses applied over a transformer 100 from a source 110. The amplifier includes control windings 12, 22 which act in the opposite sense to the load windings, and the duration of the unidirectional pulses in the load is inversely proportional to the control signal applied to terminals A, B. In a modification, Fig. 3, each load winding is connected in series with a separate direct current source 52, 53, and since the two sources are of opposite polarities a train of alternating pulses is established in the load. An alternative embodiment is shown in Fig. 2 comprising two similar amplifiers each with its own direct-current source 54, 55 and gating transistors 60, 70, 80 90. The amplifiers are connected in push-pull relationship to a common load, and include a bias circuit comprising windings 14, 24, 34, 44 which is arranged to disable one or other amplifier depending on the polarity of the control signal applied to windings 12, 22, 32, 42. In a modification, Fig. 4, the polarities of the control windirgs 22 and 32 and the secondary windings 108, 109 of the transformer 100 are reversed and an alternating pulse output is established in the load as a result.

Title: Process and apparatus for the production of artificial filaments
IPC: D01D5/253
Filed: 1957-04-17
Abstract: The process of the parent Specification (wherein monofilaments of a thermoplastic organic high polymer, such as polystyrene, discharged from an extrusion die head are adjusted to their orientation temperature by contacting the filaments with a heated moving surface and are thereafter stretched at this temperature) is modified in that the cross-section of the filaments comprises at least three webs or ribs radially disposed with respect to a central core portion, the diameter of which is of the same order of magnitude as the thickness of the webs or ribs, the monofilaments being formed by melt-spinning the polymer through orifices having a shape adapted to impart to the filaments the desired cross-section.  The filaments are stretched while being maintained at the temperature at which they are to be oriented, which may be between 210 DEG  and 300 DEG F.  The web or rib portions of the monofilaments are preferably of considerable radial length compared with the diameter of the core portion and are preferably regularly disposed radially to the core of the monofilament.  The webs or ribs may all be of equal thickness and of uniform thickness from their roots to their free ends.  They are also preferably of equal length radially.  The unoriented extruded filaments may be brought to the desired orientation temperature by passing them in a sinuous path over a series of hollow driven rolls maintained at a predetermined temperature by the circulation of steam through them.  The filaments of the invention retain more liquid and are stiffer per unit weight and length than filaments of circular cross-section and are thus more suitable for the manufacture of paint brushes and scrubbing brushes.  They are also more easily split longitudinally at their ends.

Title: Record card verifying machine
IPC: G06K5/00
Filed: 1966-03-23
Abstract: 1,081,828. Verifiers. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 23, 1966 [May 3, 1965], No. 12714/66. Heading G4M. Automatic verification of non-significant zeros and blank columns is performed under the control of a programme card. The machine described is basically similar to that disclosed in Specification 688,438 in which data is set up on interposers from a manual keyboard, and as each column of a detail card is sensed by pins, the setting of the pins and interposers is mechanically compared, verify contacts being opened if disagreement occurs. In the machine as modified by the present invention, a zero or blank is set up on the interposers in response to the sensing of a control hole in the programme card. Automatic left (or non-significant) zero verification.-The sensing of a 2-hole in the programme card initiates a dummy cycle and prevents the keyboard being operative. In the dummy cycle, the zero interposer is set and the programme and detail cards are advanced one column, the programme card being one column in advance of the detail card. A function set up by the programme card is continued by the presence of 12-holes in subsequent columns of this card. The zero is set up on the interposers in each cycle, and both cards are advanced column-by-column while agreement exists. When disagreement is detected, the machine performs a further " false " cycle in which the control circuitry is conditioned for manual verification; and then stops. The operator should then check that the first non-zero digit on the detail card appears in the correct column before proceeding with manual verification in the normal way. Blank column verification.-This operation is also initiated by a 2-hole in the programme card. A dummy cycle is performed as in the ALZ operation. Since the zero interposer has been set, the first blank column of the detail card causes the verify contacts to open when the detail card is sensed in the next cycle, and a " false " cycle is performed as in the ALZ operation. The operator now presses a key such as the " skip " or " space " key to select blank column verification, and subsequent cycles are performed automatically to verify the blank columns, none of the interposers being set in these cycles. When a non-blank column on the detail card is sensed, the machine performs a further " false " cycle and is again conditioned for manual verification unless a further automatic function has been programmed.
