Title: Tobacco stemming machines
IPC: A24B5/06
Filed: 1931-10-15
Abstract: 383,021. Tobacco-stemming machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Comas Cigarette Machine Co.; Salem, Virginia, U.S.A.) Oct. 15, 1931, No. 28703. [Class 130.] The tobacco leaves are fed from left to right in Fig. 1 by two sets of conveyer bands 84, 83, the first of which holds the leaves so that their butt ends are stemmed by a stripping- device 23, after which the butt ends are gripped by the second conveyer 83 so that the remaining portions of the leaves are stemmed by a second stripping-device 22. The stripping-devices 22, 23 each comprise superposed pairs of sprocket chains 35, 24, Fig. 5, each pair being connected by short stripping-members 61 composed of wire bristles with their outer ends bent backwards. These members meet together along the adjacent runs of the chains and engage the tobacco leaves between them. The chains are tensioned by sprockets 29, 47 adjusted by screws 34, 52. The upper sprocket chains are supported by a yoke 38, 42 adjustably connected at its upper end by a bolt 44 to a fixed yoke 43. By this means, the strippers 61 can be adjusted as shown in Fig. 5, so as to be farther apart at one end than the other, in accordance with the taper of the leaf stems. A pressure plate 54 arranged between the lower runs of the upper chains is also adjustable in inclination about its pivot 56 by means of a cam 58. The strippers are cleaned by rotary brushes 72, 78 driven from the sprockets 47, 29. The conveyers 83, 84 each comprise superposed endless belts 144, 145, Figs. 1, 12, and 13, carried by plates 121 jointed together and fitted with rollers 126 which engage sprockets 117. The adjacent runs of the superposed belts are pressed together, so as to grip the tobacco leaves, by endless roller chains 130 which bear against supports 139, 140, the upper of which 139 is pivotally mounted and adjustable to vary the pressure on the leaves. The upper belts 144 are formed of rubber backed with fabric, and the lower ones 145 of leather. If the tips of the stems are to be removed with the leaf portions, a pair of superposed scoring- discs 146 are provided adjacent the first conveyer 84 so as to weaken the stems near the tips. The tobacco leaves are fed to the conveyer 84 by a belt 163 and by extensions of the lower belts 145 of the conveyer 84 arranged alongside the belt 163 as shown in Fig. 1.

Title: Method of measuring frequency dependent group delay distortion
Inventor: HOFFMANN GUNTHER
IPC: H04B3/462
Filed: 1965-07-13
Abstract: 1,117,475. Measuring group delay. U. GOLTERMANN [trading as WANDEL U. GOLTEBMANN]. July 13, 1965 [Aug. 8, 1964], No.29674/65. Heading G1U. Group delay distortion occurring in the transmission of a signal through a four terminal network is measured by applying to the network a carrier frequency amplitude modulated by a constant split frequency which is recovered by demodulation at the network output. The carrier frequency is periodically changed at a changeover frequency between a measuring frequency and a standard frequency, the standard being transmitted with an identification frequency. The size of the periodic phase variation indicates the difference of the group delay at the measuring frequency and the group delay at the standard frequency. All the auxiliary frequencies required at the transmitter (split, identification and changeover frequency) are derived from one auxiliary frequency generator in the transmitter and similarly the auxiliary frequencies required at the receiver are derived from one auxiliary frequency generator in the receiver locked in frequency to the received split frequency. In order that the measurement may be made in a very short time, it is arranged by means of gating circuits operated from divider chains providing signals having frequencies related to the auxiliary frequencies that a measurement shall be carried out immediately prior to a change over between carrier frequencies, so that transients induced by a preceding change will have died away. Fig. 4 shows a suitable receiver circuit. The carrier signal received from the network under test is demodulated at 10 to provide the split frequency and passed via a band pass filter 13 to a phase sensitive circuit 14 which must also be provided with a zero phase shifted signal b at the split frequency. This is developed by the generator 16 and binary dividing circuits 17, 26. The identification signal on the second carrier is passed via the band pass filter 11 and shaping circuit 12 to lock the divider chain 26, 27, 28, 29 and two signals from this chain operate an AND gate 30 to provide a signal which operates the gate switch 25 at an appropriate time for measurement purposes. The output from the phase sensitive circuit 14 is passed to a controlled rectifier 15 operated at the change over frequency provided by signal e. The rectifier output indicates the required group delay. The circuitry for transmitting the appropriate measuring signals to the input of the network under test is arranged to ensure that the identification signal is applied to the second carrier at predetermined times only, related to the times of change over between the carrier frequencies, so that the correct sequences at the receiver will be achieved.

Title: Improvements in or relating to control systems for aircraft
Inventor: PATEMAN JACK EDWARD
IPC: G05D1/00
Filed: 1953-10-27
Abstract: 777,938. Automatic steering control systems. ELLIOTT BROS. (LONDON), Ltd. Jan. 27, 1955 [Oct. 27, 1953], No. 29700/53. Class 38 (4). [Also in Group XXIX] An aircraft control system in which movement of the pilot's control 4 connected to a pilot valve 3 operates the control surface 1 through the intermediary of an hydraulic servomotor 2 and which includes artificial feel at 5, comprises a first linkage system 13, 15 and 16 connecting the control to the movable member of the servomotor whereby movement of the member is transmitted to the control through this first linkage which has a constant length under normal load conditions but which varies in length under excess loads, a second linkage system 17, 19 and 11 connecting the control to the movable member and pilot valve, and operable, upon variation in length of the first linkage, to operate the pilot valve, and means controlled by an automatic pilot 22 and connected to the second linkage system whereby the latter is operated independently of the first linkage system to operate the pilot valve. With the friction or hydraulic clutch 16 engaged, a signal from the automatic pilot passes through an amplifier 23 and controller 24 to position a piston valve 20 whereby the piston 19 moves in its cylinder 17 and through the lever 11 moves the pilot valve, servomotor and control surface. Movement of potentiometer contacts 26, 29 on the two pistons send signals to the amplifier. As the control surface approaches its setting the signal from the potentiometer 26 tends to balance that from the automatic pilot and the signal from the potentiometer 29 adjusts the valve 20 to centralize the piston 19 and close the valve 3. Movement of the servomotor is transmitted through the clutch 16 and lever 13 to the control 4. For manual control, the switch 27 is opened and the parts 17, 19 become a rigid link. Since the points of connection of the levers 11, 13 to the piston 12 are fixed, movement of the control 4 makes the clutch slip when it positions the valve 3 and movement of the piston 12 recentres the valve 3 through the lever 11. In another embodiment one end of the cylinder 17 and of the clutch 16 is anchored, the other end of the clutch and piston 19 are connected to the ends of another pair of levers, one having a fixed fulcrum and the other pivoted to the valve 3 and having their other ends connected to the piston 12.

Title: Improvements in or relating to inserted blade cutters for milling-machines, lathes and other metal-cutting machines
IPC: B23C5/24
Filed: 1928-10-15
Abstract: 304,117. O. K. Tool Co., Inc., (Assignees of Weddell, R. R.). Jan. 14, 1928, [Covention date]. Milling-cutters ; tools and tool-holders. - The inserted teeth of machine tool cutters, whether rotary or non-rotary, are tapered and are held in similar recesses in a body by wedge action, transverse movement of the teeth being prevented by one or more serrations on the teeth and recesses. The serrations are arranged parallel to the direction of taper of the recesses but inclined to both of two angularly disposed cutting edges so that lateral adjustment of a tooth by means of the serrations will give simultaneous individual adjustment to the two cutting edges on the tooth. As applied to a face milling- cutter the body 10 has tapered recesses 12 for the reception of teeth 11 which have cutting edges at 18 and 19. Fig. 4. The recesses are inclined to radii of the body and at an angle d to an axial plane in order to provide cutting rake for both edges. Serrations 15 on the. teeth, of V-shaped or other section, coact with similar serrations on one side of each recess and are arranged at such an angle to the cutting edges that in moving a tooth from one serration to the vent in order to compensate for grinding, the two cutting edges will be moved to the dotted line positions in Fig. 4, thus giving each its correct adjustment according to the amount of wear which it usually receives. The serrations may vary progressively round the cutter in their distances from the axis of the body so that in moving a tooth from one recess to an adjacent. one it may be adjusted by a small portion of the pitch of the serrations. As applied to a side or grooving cutter the teeth 22, Fig. 8, are parallel in the axial direction of the cutter and tapered radially. In moving a tooth axially the cutting edges are adjusted to the dotted line positions shown. The teeth are arranged with their radial edges 22<1> alternately on opposite sides of the cutter and alternate teeth are inclined in opposite directions to the axis of the cutter. In a non-rotary tool also the tooth has two cutting edges which are adjusted simultaneously with respect to a shank when the tooth is moved from one serration to the next.
