Abstract: 393,455. Window - cleaning apparatus. WEBER, G., 13, S³dstrasse, Halberstadt, Germany. Sept. 28, 1932, No. 26955. [Class 19.] Apparatus for cleaning windows comprises a number of cleaning tools arranged side by side in a cleaning head and adapted to be rotated by a common drive, cleaning tools in the corner of the head being arranged obliquely to facilitate cleaning the corners of windows. In the construction shown in Figs. 1 and 3, brushes 11 are adapted to be rotated through gearing from a flexible shaft 16 driven by an electric motor. Inclined brushes 12 for cleaning corners of windows are connected through gearing 7, 8 with the shafts 3 of the brushes 11. The casing 1 is provided with an extension 13 connected to a hollow handle leading to a source of suction operated by the electric motor. Cleaning liquid may be fed to the window from a container, through pipes 27, 26, and channels 25 leading to holes 24 in the casing. The cleaning head A is detachable and may be replaced by a polishing head B, Fig. 5, which comprises an endless cloth 32 placed around rollers 30 and a sheet-metal element 31. The cloth is stretched by adjustable rollers 33 and is driven by motion imparted to the rollers 30 by means of the flexible shaft 16. The cloth is kept clean by a fixed brush 41. In a modification shown in Figs. 7 and 9, the electric motor 42 and suction fan 53 are mounted in the cleaning head A. Dust from the windows is sucked up through tubes 51, channels 55 and apertures 54 and led off through a pipe 56. Cleaning is effected by three main brushes 11, four inclined brushes 12, and four small brushes 11a. In a further modification shown in Fig. 11, a central cylindrical brush 59 is located between two sets of three main brushes 11, all of these brushes together with four corner brushes being driven through gearing from the motor 42.

[Also in Group XXXVIII] Apparatus for measuring recurring distances, e.g. tooth pitch on gears or racks, comprises two feelers for engaging surfaces the distance between which is to be measured, one of the feelers being rotatable, each of the feelers being associated with one electrode of a capacitor determining the frequency of an oscillator which is indicative of the spacing. As shown (Fig. 1), the tooth pitch on a gear-wheel 51 is measured by the spacing between a fixed feeler 62 and a spring-loaded feeler 55 rotatable about a pin 58. Fixed arms 64, 65 help to locate the device relative to the gear 51. The feelers and arms are carried by a plate 54 supported by balls on a fixed base-plate 52, so that plate 54 is freely movable manually to the position shown, where the tips of arms 64, 65 engage with the roots 68 of the teeth, and the ends of feelers 55, 62 are in contact with adjacent tooth faces 59, 69, and plate 54 moves with the gear 51 while the measurement is being made. Feeler 55 carries an electrode 60 (Fig. 3) which co-operates with a fixed electrode 61 to form a capacitor determining the frequency of an oscillator whose output is mixed with that from a fixed frequency oscillator, and the beat frequency, which is recorded and indicated on a meter, indicates the variation in tooth pitch.

As shown in connection with a vertical-flued regenerative oven, in which reversal is effected between two half-wall groups of the heating-flues E and the gas is supplied through conduits H, HA extending from the two sides of the bench, the decarbonizing air is supplied through pipes H<3>, HA<3> beneath the regenerators, and vertical passages H<2> opening into the conduits H, HA at their inner ends. To prevent choking of the passages H<2> by broken gas nozzles, their upper ends are made in the form of narrow slots, and catch-pits H<6> are provided at their lower ends for the reception of small fragments which may pass the slots. The reversal of the air supply between the passages H<3>, HA<3> is controlled by valves L adjacent to, and operated simultaneously with, the ordinary reversing-valves, J, and the supplies of air are regulated by interchangeable perforated diaphragms fitted in the pipe connections beteen the valves and the passages H<3>, HA<3>. When the combustion air for the oven is supplied under pressure, the right-hand vertical flue H<2> leading to the gas conduit HA is connected to the left-hand air main, and vice versa.

Abstract: 1482820 A tee-off device K A POORTMAN 1 July 1975 [4 July 1974] 27753/75 Heading A6D A tee-off device for inducing golfers to keep their "eye on the ball" emits a flash of light when the ball is teed off, the colour of the light flash being detained by the relative position of a number of transparent differently coloured windows to a light source. In the embodiment shown, a ball 26 placed on a tee 25 in turn placed on a platform 4 causes downward axial movement of shaft 11 relative to housing 1, the axial movement being limited by a pivoted lever 15, 16 connected at one end to a cam 27 on shaft 11 and having a weight 18 at the opposite end. A further pivotally mounted lever 12, 13 engages at one end with a cam 28 on shaft 11 and at the other end selectively with gear wheel 5 by means of projection 19. When the ball is placed on the tee, projection 19 is caused to disengage from gear wheel 5 allowing rotation by clockwork or battery operated drive mechanism 2, via shaft 7. Also mounted on shaft 7 is gear wheel 6 engaging a gear wheel 9 which has a number of differently coloured transparent windows 10. Rotation of gear 9 causes the different windows 10 to pass between bulb 10" and opening 10' in cover 1'. When the ball is teed off platform 4 moves axially upwardly with respect to the housing 1 under the influence of weight 18 and projection 19 on lever 12, 13 engages with gear wheel 5 to cease rotation of shaft 7 and have gear 9. The flash of light is caused by the upward movement of a cam 21 on shaft 11 momentarily engaging electrical contacts 22, 23. The colour of the light flash in dependent on which window 10 is between bulb 10" and opening 10'. To check if the player has seen the flash of light and its colour the platform 4 may be depressed such that cam 21 engages contacts 22, 23 without operating the drive means. The housing is constructed to enable it to be placed in a hole in the ground and retained therein. Other embodiments described include the replacement of lever 15, 16 and weight 18 by a spring, the use of rubber tees of varying sizes provided with a length of cord having a pin attached, providing cover 1' with a layer of artificial turf, and the provision of a transmission having discrete teeth, e.g. a maltese cross transmission, for ensuring correct alignment of a widow 10 between bulb 10" and opening 10'.
