IPC: F01D5/14
Filed: 1967-07-19
Abstract: 1,198,515. Turbine and compressor blading. W. DETTMERING. July 19, 1967 [July 21, 1966], No.33237/67. Heading F1T. A deceleration blade lattice for supersonic inflow, for the rotor or stator of a turbo machine, such as an axial-flow compressor or turbine, comprises two inter-digitated rows of blades. The supersonic inflow is retarded to subsonic in region A by a normal shock wave stabilized by throttling. Thereafter, the flow is deflected in region B which is of substantially constant crosssection, and passes through regions C and D of constant or slightly divergent cross-section to a deceleration region E of divergent cross-section. The flow-path may be slightly deflected in the reverse direction in region D, as shown, to substantially equalize, by centrifugal effects, the pressures at point 2 and the directions of flow of the part-flows issuing from regions C and D. The discharge flow may be purely axial as shown or may include a peripheral component. In the embodiment of Fig. 3 (not shown), the deflecting and deceleration regions are both arranged in the downstream blade row, the blades of the upstream row being very thin and substantially straight with their leading edges each defining an included angle of about 6 degrees or less.

Title: Fluid flow proportioning valve
IPC: F15B13/02
Filed: 1957-10-28
Abstract: 852,687. Valves. NEW YORK AIR BRAKE CO. Oct. 28, 1957 [Nov. 16, 1956], No. 33512/57. Class 135. A flow proportioning valve comprises a common line 11 communicating with branch lines 13, 14, wherein each branch line has an adjustable needle type restrictor and a throttling valve 46, 44 and 47, 45 respectively, arranged in series and producing a control pressure therebetween in response to flow. Motor means associated with each throttling valve are responsive to unbalance of the control pressures to move the valves to maintain a constant pressure ratio between the control pressures, as set by the restrictors, and hence a constant flow ratio through the valve, whether it is acting as a mixing or dividing valve. The throttling valves may be formed on a common spool 24 and the ends 26, 27 of the spool acting in cylinders 36, 37 which also house movable piston-like abutments 34 form the motor means, the outer ends of the cylinders communicating with common line pressure through passages 33 and the inner ends with the control pressures through passages 31, 32. When the valve is acting as a mixing valve the abutments 34, 35 move to the outer ends of the cylinder under the pressure difference between the common line and control pressures caused by the restrictors 46, 47 and the valve spool is operated directly by the control pressures, but when the valve is acting as a dividing valve the pressure difference causes the abutments abut the ends of the valve spool to provide a balanced loading which reverses the effect of the control pressures on the valve spool.

A method of setting a tubular rivet comprises assembling the rivet and a mandrel to the workpieces, forming a pull groove in the mandrel, gripping the mandrel at the pull groove and applying an axial force to set the rivet. An apparatus for performing the method comprises a nose assembly 12 for fitting to a standard pull gun 11. The nose assembly 12 includes an outer tube 20 having an anvil 24, and slidable upon a collet 28 which is attached to the piston rod 30 of the pull gun. The collet has a frusto-conical bore 32 and a relief groove 34 and contains a plurality of chuck jaws 54, Fig. 2 (not shown), each of which has a single tooth 56, the jaws being urged forward by a spring 40 acting on a chuck follower 46. Telescopic tubular members 44 and 52 define a passage-way through which the broken-off mandrel portions are ejected. A rivet 66 and mandrel 72 are passed through workpieces 16 and 18 and the shank 76 of the mandrel inserted axially between the jaws 54. When the collet 28 is moved axially away from the anvil the jaw teeth 56 indent the mandrel and form a combined pull- and break-off groove 76. The radial inward movement of the jaws is limited by the jaws abutting in the bore 32, to determine the root diameter of the groove 76. The cross-sectional shape of the groove is determined by the tooth-shape, and teeth which are chamfered on the front and rear surfaces are described, Figs. 4, 6, 7 (not shown).

Abstract: 854,512. Weighing apparatus. BIBBY & SONS Ltd., J. Oct. 29, 1958 [Oct. 30, 1957], No. 33813/57. Class 143 [Also in Group XXIX] A machine for delivering material at a constant rate comprises a conveyer belt B on a counterbalanced beam A pivoted at C so that it tends to move down under the load on it, a hopper gate E controlling the feed of material on to the belt, and a force balance unit M sensitive to the downward movement for pneumatically adjusting E via a comparator O, the output from O being made proportional to the increment of pressure detected by M and the time-integral of the increment. The conveyer pivot G, formed by a flexible torsion strip, lies in the plane of the belt B and centrally of the exit of the hopper F and has a balance weight J on one side. The rate of delivery is measured by the weight of material on the belt producing a pneumatic signal from the force balance signal converter M which is compared in the controller O with a demand pressure set by a remote unit Q. A piston N actuates the gates. In a convenient form (Fig. 3, not shown), the unit M is located above the conveyer belt and operated via a lever, the belt drives a device which, should the belt break, shuts down the machine automatically and the belt driving motor is mounted on the balance beam A or may be within the belt pulley C.

Abstract: 1284386 Absolute valve amplifiers; detecting signals within amplitude limits BENDIX CORP 13 July 1970 [17 July 1969] 33861/70 Heading H3T A circuit for detecting whether a signal or the difference between two signals is between amplitude limits comprises an absolute value amplifier arrangement 1 for producing a unipolar signal having an amplitude corresponding to the input signal irrespective of its polarity and a level detector 25 receiving the unipolar signal and a reference signal, the amplifier having two feedback paths respectively for positive and negative signals. The absolute value amplifier arrangement passes positive signals directly to its output 5 via resistor 7, the amplifier having zero gain due to feedback through diode 17. For negative signals the amplifier produces a positive output and the values of the feedback resistor 19 are chosen to produce the same gain between 3 and 5 and an output of the same polarity as for positive signals. The level detector changes its output between its two saturation conditions when the input at E2 passes a threshold value set by a variable resistor 29. Variable hysteresis is provided by an adjustable potentiometer 33, 37. The circuit may also be adapted to indicate when the difference between input signals is within the limits (Fig. 2, not shown). In this case the additional input of the same sign is applied to amplifier 11 through an inverter (45) and a further resistor (39) corresponding to 9 a further feedback resistor (41) corresponding to 7 being connected to the output of the inverter.

Title: Improvements in or relating to electric remote control systems for television apparatus
IPC: B25J3/04
Filed: 1936-12-11
Abstract: 486,604. Electric control systems. OKOLICSANYI, F. VON. Dec. 11, 1936, No. 34058. Convention date, Dec. 12, 1935. [Class 40 (i)] [Also in Groups XXVIII and XL] In a system of remote control for an apparatus, e.g. a robot, incorporating a television transmitter and a sound transmitter, the television transmitter is rotatably mounted and is controlled by signals generated by movements of the television receiver. The apparatus thus facilitates changing of the field of view of the transmitter to correspond to changes in the direction of viewing, e.g. by head movements, of the controlling person. Fig. 1 shows a robot apparatus embodying a sound transmitter k, a television transmitter m and a loudspeaker l mounted on a rotatable support and a movable limb r. The apparatus k, m, l is connected to corresponding receiving and transmitting apparatus b, c, a mounted on the head-band of the controlling person. Movements of the head-band effect the transmission of modulated carrier control currents over the channel h,s and the operation thereby over the circuit o of apparatus for producing corresponding movements of the apparatus k, m, l. An arm f and fingers g may be operated to cause similar movements of the limb r by transmitting modulated carrier currents of different frequencies over the channel h,s. In order to transmit back to the controlling person the effects of external interference on the limb r, e.g. when the limb engages an obstruction, signals are reverted back to the control station by apparatus t to operate apparatus which produces similar effects on the limb f. Fig. 3 shows a system for transmitting such effects. Movements of the hand e vary a resistance f which, through apparatus g, controls a contact arm h co-operating with a pair of resistances i, k on a control glove a. The resistances control magnets m, n which influence the glove a in a manner corresponding to the movements of the contact h and limb e. The movements of the body and feet of a robot may be transmitted in a similar manner and the movements may be recorded on a disc or film and reproduced later if desired. Specification 472,009, [Group XL], is referred to. The Specification as open to inspection under Sect. 91 describes an internal-combustion engine for effecting operation of the limb of a robot constituted by a series of collapsable chambers which are extensible under the action of fuel ignited by a sparking-plug. This subject-matter does not appear in the Specification as accepted.
