Title: Height adjustment for garden tools
Inventor: TRELFORD ALAN
IPC: A01D34/54
Filed: 1984-09-28
Abstract: A height adjustment mechanism for a garden tool comprises a cylindrical height adjustment member (7, Figure 1) rotatably mounted in the body of the tool and coupled at its inner end to a roller 40 of the tool. An axle 14 on member 7 co-operates with a centrally located bore 14a of roller 40 whereby the axis of rotation of the roller 40 is off set from that of the cylindrical member 7 so that, by rotating the latter, the height of the tool body from the ground can be adjusted. A locking projection (19, Figure 2) is formed on a tongue (15) in the cylindrical member (7) and can engage in a plurality of recesses 37 in the tool body to lock the cylindrical member (7) in a plurality of discrete rotational positions. The tongue (15) carries a button (18) by which it can be depressed, to release the lock and permit rotation of the cylindrical member. <IMAGE>

Patent GB-850654-A (GB)
Abstract: 850,654. Photo-electric telemetering control. LANDIS & GYR A. G. Jan. 26, 1957 [June 27, 1956], No. 20200/57. Class 40(3). [Also in Group XXXVI] In a telemetering transmitter a photocell is connected in the control circuit of an unstable multivibrator having a pulsed output of variable frequency, and a current or torque balance compares the electrical quantity to be measured with an electrical quantity fed back from the output of the multivibrator, the movable member of the balance being provided with an attenuator arranged to move between a light source and the photo-cell to control the amount of light passing to the cell. A current fed to a measuring coil 12 of a current balance 11 causes deflection of an attenuator 14 to influence the light reaching a photo-cell 16 from a source 15, the amplified output of the photo-cell being applied to the grid resistors 28, 29 of an unstable multivabrator 25 which is arranged to operate at a frequency dependent upon the voltage applied to the resistors 28, 29. The output of the multivibrator is fed to a transmission line through a condenser 34, and to a transformer 35 which is brought into the saturated state by the impulses. The secondary of the transformer 35 feeds through an adjustable resistance 39 to a rectifier 38 which supplies to a compensating coil 13 of the current balance 11 a current proportional to the impulse frequency of the multivibrator. By the feedback of current to the coil 13 the impulse frequency of the multivibrator is maintained proportional to the input current applied to the measuring coil 12, irrespective of fluctuations in temperature and in the operating voltage.

Abstract: A container for flowable material such as liquids or powdered material comprises an outer shell and an inner shell, the outer shell being of rigid or semi-rigid construction and having a generally prismatic shape 10 and the inner shell being flexible or rigid and receiving the material to be contained. The outer shell is formed as a tube open at the top and bottom ends and has a closure element such as a bottom or lid 18 or support element for a detachable lid (Fig. 5) secured to one of the open ends by a rolled seam joint. The top of each side wall is rolled to produce a double thickness seam 20 parallel to but jogged inwardly of the main wall portion and an upwardly standing flange 22 defining a narrow socket between it and the seam 20 into which a lip of the lid fits, the projecting part of flange 22 being turned over onto the top of the lid. An optional outlet pipe may be provided (36, Figs. 6-8) and the lid may include a central opening for a screw threaded ring shaped adapter for receiving a threaded cap (Fig. 2). The inner shell may be of cross laminated high and low density polyethylene film, a rigid planar sustaining element being secured to at least one side to prevent creasing (Fig. 6). The outer shell may comprise two L-shaped members welded together at diagonally opposite corners. The inner shell may be attached to the outer shell in the region of the opening in the lid. <IMAGE>

Title: Central heating boiler arrangement
Inventor: VERNON JOHN RICHARD
IPC: F24D19/10
Filed: 1986-01-17
Abstract: A central heating boiler arrangement has a flue gas condensation economiser 12 fitted to the exhaust gas flue 11 of the boiler 10, to recover heat from the exhaust gases. To maintain the economiser surfaces cool enough to ensure condensation takes place, the outlet flow from the boiler is divided into two portions one of which (from B to A) is circulated through the radiators and the other of which is fed along path 21 back to the boiler inlet. The return flow 14 from the radiators is passed through the economiser 12 and is then mixed with the portion fed back to the boiler, in a mixing chamber 15. The division ratio of the boiler outlet flow is adjusted, for example by valve 24 or by temperature-sensitive valve 23, to ensure that the flow rate through, inlet temperature to and temperature rise across the boiler are all within the design ranges therefor, whilst allowing a radiator return temperature substantially below the dew point of the flue gases. <IMAGE>

Patent GB-2177847-A (GB)
Title: Electron lithography
Inventor: TURNER DAVID WARREN
IPC: H01J37/317
Filed: 1986-06-06
Abstract: A method of electron lithography is described, in which electrons emitted from a source (1) in a pattern are directed onto a target (21) in a corresponding pattern by being constrained to follow magnetic lines of force (17) generated at (9), (11) and extending between the source and target. The target pattern may be a reduced form of the source pattern. The lines of force may be parallel to one another for a limited distance from the source and/or target, to eliminate depth of field problems. A detector (29) may detect electrons leaving the target, for use in the correction of registration errors between the source and target. Additional magnetic fields, and electrostatic fields, may be applied by components (23), (25), (27). The source and electrostatic fields may be pulsed. <IMAGE>
Patent GB-2382414-A (GB)
Title: Signal detection
Inventor: GARDNER BRIAN R
IPC: G01S7/02
Filed: 1986-07-11
Abstract: A wideband signal detection system includes an antenna array which feeds at least one receiver channel (6, 8). In each channel (6) the received signal is mixed with a linearly swept reference frequency generated by a local oscillator (16), to convert any signal received by the antenna array into a chirp signal with a timing relative to the sweep rate of the local oscillator which represents its frequency. The series of chirps is mixed in at least one further mixer and filter stage (26, 28) and then fed to an A-D converter (38) which is connected to an input of a digital filter (40) which effectivley carries out a Chirp Z Transform on the input series of chirps. The filter (40) is matched to the sweep rate of the local oscillator (16) so that each input chirp is compressed into a pulse and the output of each receiver channel is a pulse train in which each pulse represents a received signal. The coefficients of the filter (40) are adaptively set out so that a desired pulse input is always produced for a mid-band carrier input training signal. For DF purposes, if the input signals to the receiver channel are the zero and first order outputs of a Butler matrix (4), a processing means (42) compares the phases of each corresponding pulse to derive the bearing of the source of that received signal.
