The shaft assembly is automatically returned to its non- rotatable position by the bias spring upon release of the actuating knob. The shaft assembly is in two parts which are screwed together and is hollow for limited axial movement on a spigot (15) formed on the backplate of the housing. The actuating knob (7) may be locked on to the spigot by key 54 such as to allow only limited axial movement between the knob and the spigot and to retain the cover (2) on the back plate (1), so preventing unauthorised removal of a roll. <IMAGE>
Patent GB-2115349-A (GB)
Title: Debit card
Inventor: SOTHCOTT PETER
IPC: G06K19/14
Filed: 1981-08-25
Abstract: A debit card, e.g. for telephone call-making purposes, has its value indicated by a number of value-unit indicating patches or spots of a material which changes its state significantly in response to the application of a burst of light or heat. One such material which is normally translucent goes dark when thus irradiated. When the card is placed in - or adjacent to - the reader, the latter first checks for the presence of unchanged spots, and then when it finds such a spot it reverses its state. This detection followed by reversal indicates that the card is valid, and an output is sent to the associated equipment - e.g. a telephone exchange.

Title: Improved DC machine control system
Inventor: OHBA SHUNJIRO
IPC: H02P7/298
Filed: 1981-12-24
Abstract: Whilst DC electric traction motors are widely used because of the relative simplicity of operation and ability to provide high torque, there are many applications where the output power of the motor is significantly limited at higher cruising or passing speeds if the motor is designed to achieve optimum efficiency at immediate speeds such as those used in city driving, and vice versa. In order to obviate the above disadvantage, the control system comprises generator means for generating (at 26 and 40) a pulse signal having a predetermined frequency and pulse width, demand signal means for producing (at 32) an electrical demand signal corresponding to the demand on said DC machine, armature current sensing means coupled to said armature winding for producing (at 20) an electrical drive signal corresponding to the armature current in said DC machine, control circuit means (24) coupled to said generator means and responsive to said demand signal and said drive signal for adjusting said pulse width of said pulse signal (at 26) control circuit means (36) coupled to the generator means and responsive to the demand signal for adjusting the pulse width of the pulse signal (at 40), and means coupled between said control circuit means (24 and 36) and said armature winding and said field winding, and responsive to said pulse signals for applying signals to said armature winding and said field winding which vary in accordance with said adjusted pulse width, whereby the coefficient of field excitation is varied in accordance with the corresponding demand and armature current to substantially increase the efficiency of the DC machine. <IMAGE>

Title: Valves assembly for pressurised dispensers
IPC: B65D83/14
Filed: 1982-02-23
Abstract: In a valve assembly for an aerosol can, the spray button 1, is pressed into sealing engagement with the mounting cup 4 during the 'gassing' process (see Fig. 2). An inwardly directed annular shoulder 18 formed in the top wall 4 of the ferrule or centre boss 5 is engaged by an outwardly facing annular surface 20 on the underside of the spray button 1, and the higher the pressure the better the seal. As the spray button no longer needs to be as flexible as hitherto it can be made of polypropylene. A complementary outward-facing shoulder 22 on the underside of the top wall 4 helps to locate the rim of the valve shell 11 and thereby to resist displacement of the gasket 10 during gassing. <IMAGE>

Patent GB-2111578-A (GB)
Title: Plastics push-in hook
Inventor: HARROD RONALD
IPC: F16B45/00
Filed: 1982-09-03
Abstract: The hook comprises a moulded plastics assembly consisting of a hook portion 10a shank 11a and nose portion 12a. The nose portion 12a is tapered and has a thread in it which effectively reduces its diameter progressively. The hook in use is screwed into a pre-tapped hole 13a in for example a cross-bar or goal-post 15a. A series of hooks are arranged along the cross-bar and goal-posts so that a net can be attached thereto. Because the hook is made of weakened plastics material it will break easily if an undue strain is applied to it. The fact that one end of the hook is of reducing diameter and has a thread in it produces an area of weakness where the hook is more liable to break. In an alternative arrangement the hook has a reduced section near the nose portion and the nose portion is arranged to be a push -in type such that no thread is required. The reduced diameter portion again provides a weak area where the hook will readily break if undue strain is applied. <IMAGE>

Title: Photometric measurement of liquids in reaction vessels
Inventor: KAYHKO KIMMO
IPC: G01N21/03
Filed: 1983-02-03
Abstract: A procedure for photometric measurement of liquids in a reaction vessel in an automatic analyser with a radiation flow perpendicular to a row of reaction vessels is characterized in that the radiation flow and the reaction vessel (1) are in movement relative to each other during the measurement. The distance between the reaction vessels is measured and the radiation flow is measured over the effective length of each vessel. By calculating the mean of the radiant flux over accepted parts of the signal, error of measurement introduced by a dirt particle or by a scratch is eliminated. A row of reaction vessels employed in the procedure, as each reaction vessel is continuous to the next, separated by a wall and the bottom of each reaction vessel (1) consists of a lens (8) focussing luminescent radiation which can be measured simultaneously with the photometric measurement. The row of vessels has an engagement member 3 with a bevel 5 engaging an engagement member 6. Alternatively magnetic engagement may be used. <IMAGE>
