Title: Improvements relating to bladed rotors for flow machines
IPC: F04D29/28
Filed: 1961-02-14
Abstract: 980,685. Transverse-flow and radial-flow blowers. FIRTH CLEVELAND Ltd. Feb. 14, 1961 [Feb. 15, 1960], No. 5439/61. Heading F1C. [Also in Divisions B3 and F2] A cylindrical bladed rotor comprises a onepiece body defining continuous annular end portions at top and bottom, blades running between and twisted inwardly from the end portions, an integral inturned bottom wall extending in a radial plane and continuous with the bottom annular end portion; and a support element at the bottom end of the body for mounting the rotor on a shaft, the support element being locked between the inwardly twisted blades and the bottom wall. A transverseflow rotor comprises a cylindrical pot B, Fig. 6, drawn from sheet metal or formed by extusion. A ring or, as shown, a disc 20 is inserted into the pot to reinforce the base 4. Longitudinal slits are then cut in the cylindrical wall of the pot by a knife or like tool, leaving unslit annular portions 2, 10 at the ends, and the cut portions are bent inwards to form blades 8. The blades hold the ring or disc 20 against the base 4. The blades can be formed by rotating the pot B intermittently through a punching station, one blade being formed at each stroke of the punch. The top of the pot B may be closed by spinning it over at 24 to lock a disc 23 against the ends of the blades 8. Alternatively, a dished disc 25 is held in place by friction. The shaft passes through a hub 21 and a hole 26<SP>1</SP> (or another hub). For a radial-flow rotor the disc 23 or 25 is omitted. Fig. 8 shows a rotor formed by nesting the portion 2 of one pot C 2  within the portion 10 of another pot C 1 . For this purpose, the portion 2 is of reduced diameter as shown. Alternatively, the portion 10 is of increased diameter. Tabs 31 at the top of pot C 1  are bent inwardly between the blades 8 of pot C 2  to overlie a reinforcing ring 5. Discs as shown in Fig. 6 may be used at each end of the composite rotor. Slight misalignment between the rotor and a driving or supporting shaft may be accommodated by a flexible connection (see Division F2) between the shaft and a rotor end disc. For the same purpose, the bearing of a support shaft may be mounted in a rubber sleeve.

Abstract: 855,795. Electric tests. GILBERT & BARKER MANUFACTURING CO. Feb. 19,1957 [April 10, 1956], No. 5565/57. Class 37 The level-sensing element of the apparatus described in Specificatior 750,858 for indicating the level of liquid in a tank is modified for the sensing of the position of a liquid interface by sealing off the interior of shield 5, either by the use of an insulating cap 30 (Fig. 3) in which the tip of sensing wire 1 is embedded, or by filling the shield with insulating material 34 such as a resin (Fig. 2). The wire 1 may have a horizontal portion at its lower end, protected from direct contact with liquid by the material sealing off the shield interior, to increase the capacitative sensing effect. By these means the interface f between a petroleum product p and water w is detected by the different capacitative loads on wire 1, the sensing element being made to follow the interface automatically by apparatus described in divisional Specification 855,796.

Title: Punching apparatus
IPC: B21D28/24
Filed: 1975-02-10
Abstract: 1493513 Punching UNIPUNCH PRODUCTS Inc 10 Feb 1975 [5 March 1974] 5578/75 Heading B3W In a punching machine, a vertically movable ram 68 is mounted at the free end of the upper arm 14 of a C frame and a tool support-arm 84, pivoted to the frame arm 14 at 76 and located between the ram and a work-table 37, is movable in a horizontal plane away from its operative position in which a tool mounted at its free end is in vertical alignment with the ram, for tool changing. A tool holder 92 has a dovetail connection (98), (100), Fig. 7 (not shown), with the arm 84 and is moved between clamp and release positions by means of a cam actuated gripper shoe (103) by a pivot lever 106. The whole arm may be changed by removing a lock nut (188) from shaft 176. The arm 84 is locked in operative position by engagement of a pin 220, mounted on the housing 70 of ram 68 and actuated by a fluid cylinder 220 in a bore 218 in the arm. A punch 112, reciprocable in a bush 122 in the holder 92, includes a spring stripper 126 and is raised after a punching stroke by a lifter device 138. A die 198 is mounted in the table 37 in retaining means including an adaptor 178 for small dies. Relative movement of the die retaining means is prevented by keys 174, 188 and 200. The ram 68 is reciprocated via a pitman 62 by an eccentric 56 angularly adjustable on a motor-driven shaft 50. On movement of the arm 84 out of operative position, a bracket (268), Fig. 4 (not shown), disengages a cam (264) on the frame arm 14 and allows a valve (262) to close. This causes fluid to maintain the pin 220 within the ram housing 70 which prevents closing of a switch 238 and thus breaks the punch circuit by disengaging a solenoid-operated clutch (not shown) between the motor 40 and the shaft 50. For use in punching a workpiece according to a template 290 clamped to a table 36, a carriage (300), Fig. 3 (not shown), supporting a gauge bar 306 is reciprocable along a rail 298 between tables 36 and 37. A stylus 328, Fig. 2, is mounted on a copying arm 318 reciprocable along gauge bar 306 and having clamps for supporting a workpiece. A normally retracted probe 330 is manually extended when the stylus has been aligned with the required hole in the template. A signal from a microswitch (334), Fig. 3 connected to the probe, when the probe engages in a hole energizes the punch circuit. Micrometer bars 336, 338 facilitate gauging.

Title: Improvements in and relating to signalling systems particularly the provision of duplex radio communication
IPC: H01Q5/48
Filed: 1921-02-21
Abstract: 180,069. Taggart, J. Scott-, and Radio- Communication Co., Ltd. Feb. 21, 1921. Duplex signalling is effected by employing two radiating aerials A1, A2 simultaneously energized by the generator b, when transmitting, the receiving circuit L3 being coupled to both aerials in such a way that the transmitting currents produce a balanced effect on the receiver. Received waves produce a predominating effect on one of the aerials and so operate the receiver. The receiver may as shown be connected to a coil L, coupled to both aerial coils L1, L2; or it may be directly connected across the points Y, Z. The inductances L1, L2 may be replaced by condensers. The aerials A1, A2 may differ in height, size, or directive properties; but it is preferred to use two identical aerials one placed for directive reception from the desired station and the other arranged to give an inferior reception.
