Title: Improvements in domestic washing machines
IPC: D06F23/04
Filed: 1941-02-19
Abstract: 547,194. Centrifugal - machines. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 19, 1941, No. 2274. Convention date, Feb. 21, 1940. [Class 23] [Also in Group VIII] In a washing machine in which an agitator 24 is oscillated for washing clothes in a tub 4, and the tub 4 is rotated for centrifugally drying the clothes, by a shaft 29 operated as by the mechanism described in Specification 452,402, the liquid being circulated during washing by a pump 18, the tub 4 is provided on its downwardly flaring side walls with an annular filter 15 for receiving liquid overflowing through openings 14, apertures 6, 28 in the base 5 and a lower chamber 7, extending outwardly beyond the side walls and having an opening 10 in the bottom. On rotating the tub after the washing operation, some of the liquid is discharged through the openings 14 and flushes the filter and some is discharged through the openings 6 until an annular layer indicated by the dotted line 32 remains. The tub is then stopped and allowed to drain, and the washing liquid may be pumped to a drain on connecting the pipe 22 thereto. Rinsing liquid is then introduced through a pipe 31 and the tub rotated, stopped, allowed to drain and finally again rotated to dry the clothes, the chamber 7 being adapted to hold all the water absorbed by the clothes. In a modification, the intake pump 18 is connected by a pipe to a trough on the inner walls of the casing 1 to catch liquid centrifugally discharged from the tub and a valve is provided in the intake pipe, the valve being closed before rinsing is effected. In addition, the openings 14 extend closer to the side walls of the tub thereby reducing the amount of liquid held in the tub during its rotation. Specification 535,318, [Group VIII], also is referred to.

Title: Thread supervision device
Inventor: REINERS WALTER
IPC: B65H63/06
Filed: 1969-01-16
Abstract: 1,241,084. Photo-electric investigation of running threads. W. REINERS. Jan.16, 1969 [Jan.20, 1968], No.2569/69. Heading G1A. The thickness of a running thread is measured by a photo-electric arrangement, the arrangement being such that while the thread is running it is kept pressed against the transparent cover 5 for the photo-cell 4 (position F 1 ), but if there is no movement in the longitudinal direction e.g. during insertion of the thread or when the thread has stopped, the tension on the thread is relaxed and it abuts against the end of prism 3 (position F 2 ), where it is held by air suction tubes 6, 7. In this latter position (F 2 ) the shadow of the thread thrown by light from at least two directions towards the photo-cell surface either falls outside the sensitive area of the cell or is minimal compared with the shadow for the thread in position F 1  and so a measurement signal is not produced. Instead of a single light source 1, a number of sources may be provided to give light beams falling on the thread from various directions. Instead of prism 3, a diffusing plate may be provided.
