Title: Combination Brush Stripping and Liquid Sealing Insert for Containers
Inventor: KELLETT LEO LAWRENCE
IPC: A45D40/26
Filed: 1967-12-12
Abstract: 1,189,498. Container closures; brush scrapers. L. L. KELLETT. 12 Dec., 1967 [12 Dec., 1966], No. 56489/67. Headings B8D and B8T. A flexible plastics insert 14, particularly for a screw-capped container, comprises a cylindrical body 16 for fitting tightly into the container neck 10, with a flange 18 for overlying the neck 10, and the lower end of the insert 14 terminates in a pair of elongated lips 24, which converge to form a generally elliptical opening bounded by coplanar wiping edges 34 which remove excess liquid from a brush applicator (not shown) during withdrawal. Owing to its viscosity the liquid takes some time to drain back, thus forming a temporary liquid seal. Specification 683,932 is referred to.

Title: Sun baths
IPC: A47C1/14
Filed: 1972-10-11
Abstract: 1374798 Sunbathing platform R OSBORNE 11 Oct 1972 [7 Dec 1971] 56875/71 Heading A4J [Also in Division H4]  A platform for sunbathing is rotatable about horizontal or vertical axes to align the surface perpendicular to the sun's rays and includes means for indicating that the rays are perpendicular to the platform. The platform 15 Fig. 4 has a foot rest 16 and is mounted on an axle fitted to a yoke 12 which itself is rotatably mounted on vertical pole 11. A detector 27 consists of an array of photo-cells 31 Fig. 3, which receive a spot of light generated from the sun's rays by an apertured disc 30 mounted above. The photo-cell outputs drive reversible motors which rotate the platform and operate piston 25 to correctly position the platform. The tracking may be intermittent and includes delay devices to avoid spurious responses to clouds or momentary blocking of the sun's rays. In an alternative embodiment the photo-cells are replaced by a disc carrying concentric circles, the position of the light spot on the circles providing a purely visual indication of the alignment.

Title: Methods and circuit arrangements for supplying dc loads
Inventor: PERSSON ERIK
IPC: H02P7/29
Filed: 1968-12-24
Abstract: 1,242,099. Control of D.C. motors. ALLMANNA SVENSKA ELEKTRISKA A.B. 24 Dec., 1968 [27 Dec., 1967; 29 April. 1968], No. 61308/68. Heading H2.T. A traction motor is supplied with D.C. pulses having a variable frequency, and means are provided to prevent the development of an A.C. component of a given frequency (f). This avoids disturbances in other equipment, when rails are used both as return conductors for the load current and parts of a signal system, for example. The motor may be supplied with pulses arranged in groups of two, the time-lag between pulses in a group being 1/2 f, and the periods between the groups being variable from 1/2 f upwardly. As shown, a thyristor 1 is connected in series with motor 2 and a D.C. source 4, a pulse generator 6 delivering triggering pulses to the thyristor. An extinguishing thyristor is fired a predetermined period after the thyristor 1 by means of a delay circuit 11. The average value of motor current is determined by signal Ur applied through diode 16 to the pulse generator 6 so that a higher signal produces a higher frequency. A signal Uk determines a pulse frequency at which the period between two pulses is 1/2 f, this signal being applied to the pulse generator 6 through switch 14 and diode 15. The switch 14 is controlled by a bi-stable circuit 20 responsive to pulses from generator 6. When Ur is less than Uk, a pulse from generator 6 closes the switch 14 and the signal Uk is selected to pass to the pulse generator. After an interval 1/2 f an ignition pulse is delivered to the thyristor 1 and switch 14 opens The signal Ur is then supplied to the pulse generator which, after a longer time interval, again delivers an ignition pulse to the thyristor 1. When Ur equals Uk, all the pulse intervals equal 1/2 f, and if Ur is increased still further the pulse frequency will increase but with the same interval between pulses. At a maximum pulse frequency, a signal is transmitted through Zener diode 19 to the unit 11 whereby the pulse length increases until the motor current becomes continuous. At low values of Ur, a selector circuit 21, 22, 23 becomes effective to increase the interval between pulses in each group and so reduce the intervals between each group of pulses for smoother running of the motor. In another arrangement, the system comprises two groups of motors each group including a pair in parallel. Each group is associated with a main thyristor, and ignition pulses are directed alternately to the thyristors, Fig. 5 (not shown).

The cap 19 has straight sides engaged by the limbs of the lever arm 6 so as to be non-rotatable on the rod 14 and guided for axial movement along the rod 14 to adjust the resilience of the spring when the rod is rotated by a handwheel fitted to the square section 20. Rubber buffers 23, 26 clamp downward and upward deflections of the seat, respectively. The mounting may be provided at one end of a bench seat the other end of which may be supported by a third U-section lever arm hinged at opposite ends to the seat shell and to a fixed foot and aligned with the lever arm 7 to which it is connected at the pivot 4 by an axle.
