Abstract: A rotatable disk (28) has circumferential rows of seed apertures (34). The back side of the disk confronts a seed chamber. Seeds picked up at the apertures (34) are carried round to a discharge zone and drop through a shoot (58). On the front side of the disk (28), when a hinged cover (16) is closed, a vacuum chamber (46) sucks the seeds to the apertures (34). The vacuum chamber is partitioned from a third chamber (62) which is opposed to the discharge zone; the vacuum is interrupted in the third chamber. Within the third chamber a cleaning device (64) acts on the front face of the disc to dislodge debris and clean the apertures (34). The cleaning device comprises a brush 66 with two circular brushes which rotate against the front face of the disk so that the bristles poke into the apertures (34). Upstream of the brush (66) there is a resiliently mounted scraper blade (68). The scraper blade alone may suffice for large seed apertures. The brush alone may suffice for small seed apertures. Both are preferably provided to cater for seed discs with different size apertures.

Abstract: A printing ribbon spool (10) for maintaining the print-out density or consistency of a printing ribbon (26) contains a sealed reservoir of ink. Within the reservoir there is provided a sealed container (40) of ink which communicates with the reservoir when it is desired to use the spool (10). Such communication can be achieved by a screw (50) piercing the sealed container. A wick (38) extends from the reservoir, past the sealed container (40), and through an opening (39) to a pad (28) in contact with the ribbon (26). Both the reservoir and container (40) are substantially sealed against the entry of air after the transfer of ink.

Abstract: A heat exchanger comprises a number of first heat transmission members (1a-1c) having apertures (13) formed therethrough, the heat transmission members extending in the direction of a secondary fluid flow (A). Second heat transmission members (2) are coupled thermally to the first heat transmission members and carry a primary fluid. The heat transmission is enhanced by producing a pressure difference between opposite sides of each first heat transmission member. Part of the secondary fluid flow passes through the apertures due to the pressure difference, but the main flow of the secondary fluid is guided along the first heat transmission members. The flow through the apertures improves the heat transfer to the secondary fluid. The pressure difference may be produced by corrugating the first heat transmission members so that the corrugations lie across the secondary fluid flow and by arranging the corrugations of each member so that they are out of phase with those of the adjacent members. This produces regions of alternately high and low pressure along each flow path between adjacent members, so that the direction of the pressure difference across the apertures reverses from one region to the next. The corrugations are preferably trapezoidal. Alternatively, the pressure difference may be produced by mounting fans in the flow paths and/or by throttling one or more of the paths.

Abstract: A control pedal apparatus for adjusting a control pedal of a motor vehicle such for example as a brake pedal or an accelerator pedal. The mechanism includes a pedal arm (14f), an adjustor member (12), and a bracket (10) secured to the fire wall of the vehicle. The mechanism allows the position of the pedal pad (22) to be adjusted slidably on the adjustor member (12) without disturbing the position of the particular control element actuated by the pedal assembly, and selectively moves the pivot axis of the pedal assembly to maintain a fixed mechanical advantage of the pedal assembly irrespective of the position of adjustment of the pedal arm (14f) on the adjustor member (12). Coacting, intersecting slots (12d, 12e) in the adjustor member and pedal arm allow the pivot axis to selectively move during adjustment of the assembly and fix the position of the pivot axis in any adjusted position of the pedal arm so that the pedal assembly pivots positively about the instantaneous assembly axis in any adjusted position of the pedal arm. One disclosed embodiment is intended for control of the push rod of the brake master cylinder and another disclosed embodiment is intended to control the throttle cable of the throttle mechanism. In each case, the adjustment of the pedal arm is accomplished by the rotation of a screw (24) engaging a nut (14e) on the pedal arm with the screw being driven by a motor (26) mounted on the bracket of the pedal assembly.

Abstract: A take-away device for a flattened tubing foil forming machine having an improved foil edge position control. The take-away device for tubing foil is formed by an extruder with a tubing blow head carrying out a blowing process. The tubing foil is flattened between a pair of squeeze rollers, which pair of rollers can reversingly turn about a vertical axis of rotation. At least two turning rods are disposed following the squeeze rollers. The turning rods are pivotable about at least one vertical axis, and have, if necessary, at least one deflecting rod. The rods are pivoted by a frame member about a horizontal axis of rotation. A winding-up device receives the flattened tubing foil from the turning rod. A measuring instrument is disposed between the final turning rod from which the tubing foil is guided to the wind-up device, and the wind-up device. The measuring instrument determines the flow position of the edge of the tubing foil and, when the flow position of the edge deviates from a normal flow position, produces a measurement signal which is dependent on the deviation. The signal is conducted to a control means which converts the measurement signal into a control signal. A frame member supporting at least one rod is connected to a servomotor for receiving the control signal for turning the frame member about a pivot having a vertical axis of rotation, in response to the control signal.

A first and a second shift register member (SR1 and SR2) are coupled via first and second storage members (MP1, MP2), respectively to the picture pick-up member (PP). The first and second shift register members (SR1, SR2) have capacitive couplings (FG1, FG2) with first and second outputs (FT1, FT2), respectively of the sensor (FT) for supplying a signal with picture information and smear as interference and for supplying only smear as interference, respectively. The sensor outputs (FT1 and FT2) are connected to res­pective inputs (AT1 and AT2) of a differential amplifier (A). It is essential that during the performance of the interference reduction the second (FT2) or the first sensor output having a DC connection (FT2, AT2) with an electrically floating potential to a (+) amplifier input (AT2) and that the first (FT1) or the second sensor output have a DC connection to the (-) amplifier input (AT1) and that both sensor outputs (FT1 and FT2) have a capa­citive output impedance. As a result an optimum inter­ference reduction at the sensor outputs (FT) is obtained by means of a charge packet comparison.
