Filed: 1918-10-31
Abstract: 129,542. Higginson, J., and Arundel, H. Oct. 31, 1918. Addition to 128,597. Vacuum apparatus.-Consists in improvements in the apparatus described in the parent Specification, according to which the pipes connecting the pressure and suction control valve with the suction and delivery valve apparatus are used as reservoirs for the liquid to be raised, an air cushion being at all times maintained between the control valve and the liquid. Fig. 7 shows a twinpipe apparatus by which a continuous delivery is maintained. A single-pipe apparatus may be constructed in a similar manner to give an intermittent delivery. To the reservoir n from which liquid is to be raised is attached a casing a containing suction and delivery valves, the casing being connected to pipes j, k, which communicate with the slowly-rotating valve u, Fig. 8, controlling the suction and delivery from the pump r. The casing a contains suction valves b, c and delivery valves d, e. The liquid from the reservoir n flows through a passage m to the under side of the suc. tion valves, and is delivered by a pipe coupled to the branch o. A relief valve p connects the delivery branch with the suction side of the valve casing.

Title: Method and means for compressing helically corrugated tubes and reflexing the corrugation sides
IPC: B21C37/12
Filed: 1943-11-03
Abstract: 569,151. Coiling helical tubes. TITEFLEX METAL CO. Nov. 3, 1943, No. 18233. Convention date, Oct. 31, 1942. [Class 83 (iv)] The pitch of a helically-corrugated tube is altered by feeding it through two spaced helical guides by relative rotation of tube and guides and then moving the guides relatively in an axial direction. A flexible helically-corrugated tube 5 may be made from a metal strip by apparatus, e.g. as described in Specification 333,674, [Class 83 (iv)], including a die 1 and mandrel 2, from which it issues helically continuously. The tube advances between two inclined rollers 19, having each a flange 21 which engages in the groove of the tube. The rollers are pivoted on a frame 14 carried by arms 9 of a shaft 6 carried from the die 1 and held as shown in Fig. 7 by latch 22 pivoted to the die. The latch is then raised to release the arms 9 and these are turned into the position shown in Fig. 1 by a handle 7 to close the grooves 38 of the corrugations intervening between the flanges 21, Fig. 6, and the die 1, the arms 9 &c. being held in this position by the slot 23 of the latch 22. The tube issuing from the die 1 will then be continuously compressed, but the tube will have its groove 38 opened by the flanges 21. In a modification, the flanged rollers are replaced by a roller 28, Fig. 9, having rings 32 free to slide axially thereon between end flanges 34 so that they can be spaced to receive the tube as formed, but, when the frame 14 is moved to the right, they close up, as shown in Fig. 8, the edges of the rings being so formed that, when so closed up, they correspond in shape to the helical groove 38 in the edge of the compressed tube 5. Specification 101,418, [Class 83 (iv)], also is referred to.

Title: Slip frequency control circuit for an asynchronous machine
IPC: H02P23/08
Filed: 1972-04-20
Abstract: 1374037 Preventing overlapping of pulses; pulse oscillators; pulse modulation circuits ROBERT BOSCH GmbH 20 April 1972 [24 April 1971] 18292/72 Headings H3T and H4L [Also in Division H2] Fig. 2 shows an arrangement for preventing pulses which occur on input terminals 44 ... 46 and are independent of each other and therefore may be coincident, from appearing simultaneously on outputs 47 ... 49 (which are connected to a reversible counter in an electric motor control system (see Division H2). Timing pulses for the JK flip-flops 413, 423, 433 and for the D flip-flops 410, 420, 430 (constructed as shown from JK flip-flops and inverters) are produced by an oscillator 330 but are supplied via AND gates 332 ... 334 arranged so that the pulses are applied to the three channels sequentially. Thus, one of a pair of coincident input pulses is delayed more than the other and coincidence cannot occur at the output. The circuit elements are in integrated form. Fig. 7 shows another part of the motor control circuit, in which square pulses are produced at input 57 at a frequency dependent upon an input voltage at 56. The voltage is applied via resistor 522 to an integrator 53 and its inverse (51 is an inverter) via resistor 521, whose value is half that of 522, is also applied to the integrator but through a F.E.T. switch 520. The output of the integrator is connected to a threshold switch 54. With 520 initially off the voltage is integrated upwards until an upper threshold is reached; the threshold switch then produces an output at 57 which is also fed back to turn on 520. The inverse voltage overrides the direct voltage so that the integrator integrates downwards, until the lower threshold is reached when the output pulse ceases and the cycle is repeated.

Filed: 1920-07-02
Abstract: 146,373. Optische Anstalt C. P. Goerz Akt.-Ges. July 22, 1916, [Convention date]. Periscopes.-In an extensible and rotatable periscope having an eyepiece which does not participate in the pulling-out movement, the extensible tube 1 of the instrument is mounted in a closed casing 3 fitted with a rotatable cap 4 carrying the eyepiece 5, the cap being so connected to the tube as to rotate therewith, whereas the elevating-parts, mounted in the casing, do not turn with the tube. The raising is effected by a slidable but non-rotatable ring 6 which engages with the foot 12 of the tube and is carried by chains or ropes 7 adapted to be driven from a motor 11. To alter the horizontal adjustment of the instrument, the cap 4 is turned. The engagement of the cap with a pinion 13 causes the rotation of a shaft 15 and of a pinion 14 which is in permanent mesh with teeth on the foot 12. The extending and rotating adjustments can be effected simultaneously.
