Patent GB-2045067-A (GB)
Title: A method and apparatus for handling sacks
IPC: F02B3/06
Filed: 1980-01-16
Abstract: In the handling of sacks the stretched out mouth (11) of the filled sack (10) is rolled at least one and a half turns about a rigidifying strip (12) and is fixed in the rolled-up state about this strip eg by stapling. The rolled-up mouth is passed down into an upwardly- open groove (17) in a lifting device (15) preferably a U-profile. The groove (17) is of but slightly greater width than the thickness of the rolled-up mouth (11) so that this is locked in the groove (17) on lifting of the sack by means of the lifting device. <IMAGE>

Title: Basic azo dyes, a process for their manufacture and their use for the colouration of synthetic polymeric materials
IPC: C09B44/04
Filed: 1980-02-04
Abstract: Blue cationic azo dyes for polyacrylonitrile are derived from a substituted 3-amino-2,1-benzisothiazole diazo component and a N-substituted p-aminophenyl coupling component containing a  beta -hydroxy substituent on a C3-6 alkylene group linking a cationic moiety to the N- atom. Unlike Basic Blue 41, the dyes have excellent fastness to steam pleating and dry heat treatments and excellent hydrolytic stability. But like Basic Blue 41 they have excellent build-up properties. Thus they combine the good tinctorial strength and build-up properties of Basic Blue 41 and the excellent fastness of the anthraquinone dyes. They also exhibit excellent light fastness and pH stability.

Title: Strain gauge pressure transducers
Inventor: GREENWOOD JOHN CHRISTOPHER
IPC: G01L9/00
Filed: 1981-10-01
Abstract: A strain gauge pressure transducer comprises a substrate 11 and a silicon layer 12 bonded thereto. The silicon is hollowed out to form a pressure chamber 18 and diaphragm 15, with piezo-resistors formed in it and connected externally 26 via deposited metal strips or runs of doped semiconductor 25.

Title: Non-slip surface coating
Inventor: SHIMMIN BRYAN FRANCIS
IPC: E04F15/12
Filed: 1982-02-12
Abstract: Rounded quartz sand particles (22) are each enclosed in a hardenable resin skin (23) which is integrated with the skins of adjacent particles and which creates an adhesion of the particles to a primed base (20, 21). A significant fraction of the particles may be remote from the base and only integrated with adjacent particles so that a contoured or embossed effect is created to provide a supplementary non-slip feature. In a process for forming such a surface coating the particles are wetted with a functional liquid, mixed with a binder related to the functional liquid and sprayed. The spraying process is powered by a progressive cavity pump with a selection of particle/resin ratio such that the pump operates under a Sigma effect. <IMAGE>

Title: Method and circuit arrangement for controlling the operation of a laundry ironing machine
Inventor: KRAUSS THEO
IPC: D06F67/00
Filed: 1982-10-05
Abstract: In an ironing machine having at least one processing path, on each processing path the distances between successive pieces of laundry are detected as time intervals, namely, seen in the direction of movement, in each case from the trailing edge of one piece of laundry to the leading edge of the next. All detected time intervals within a first time period are totalled and the sum is compared with a predeterminable first comparison value. if, after the first period, the sum is less than the comparison value the existing sum is cleared and renewed totalling takes place starting from zero. if the sum reaches or exceeds the comparison value within the first time period, a signal is emitted, e.g. displayed, to the operator. The time period for the reaching of the end of the first period is displayed. These time intervals are likewise totalled and compared within a second time period, longer than the first, with a second comparison value. If this second comparison value is reached or exceeded, appropriate switches are operated to reduce the energy consumption of the machine and, in the ultimate, to shut-off the machine. The machine may be a double-trough ironer.
