Patent EP-0105673-A2 (EP)
Inventor: HARDY FREDERICK EDWARD
IPC: C07C67/08
Filed: 1983-09-22
Abstract: A hydrophilic phenol ester derivative, especially a sulphonated or carboxylated phenol ester is prepared by reacting a C<sub>6</sub>-C<sub>18</sub> substituted or unsubstituted aliphatic carboxylic acid with a C<sub>2</sub>-C<sub>3</sub> alkanoic anhydride, and reacting the resultant C<sub>6</sub>-C<sub>18</sub> acid anhydride with a substituted phenol such as an alkali metal phenol sulphonate salt or hydroxybenzene carboxylic acid to give a C<sub>6</sub>-C<sub>18</sub> acyloxy derivative of a substituted benzene. The two stage process may be carried out in the same reaction vessel without the use of solvents. The products are useful as peroxyacid bleach precursors.

Abstract: @ The circuit arrangement comprises a speed control system responsive to a speed signal indicative of the rotational speed of an arm shaft driving the sewing needle in the same manner as in known arrangements. Although the circuit arrangement operates in the same manner as in the known arrangement when a foot pedal is other than a neutral position, once the foot pedal is released to be in the neutral position, particularly provided speed setting data is used where the speed setting data value decreases as the  J  rotational angle of the arm shaft increases. With this arrangement the sewing machine is capable of operating at a speed higher than conventional one during needle positioning with the speed being sufficiently reduced just before the needle is stopped. Thus a time length requried for the last stitch has been remarkably reduced, providing efficient sewing work without deteriorating positioning accuracy. The sewing machine speed damping curve slope may be manually selected so that a user can set a desired positioning time. Furtheromore, by selecting a needle position signal, the needle may be stopped at either at an uppermost position or a lowermost position.

Title: A tape transport device for moving the magnetic tape in both the directions of motion, particularly for microcassette decks
Inventor: PERA VITTORIO
IPC: G11B15/44

Abstract: A tape transport device for moving the magnetic tape in both the directions of motion, particularly for micro-cassette decks, in which a tilting unit (62, 62') carries one of two gear wheels (74, 74'), meshing with a pinion (58) integral with the capstan (24) and the flywheel (56), to mesh also with the main wheel (118, 118') of the related friction unit, according to the rotational direction of the capstan, in order to carry out the winding of the tape, dragged by the capstan at the normal speed, onto the take-up reel. 
     The tilting unit can comprise two plates (62, 62') separately movable in order to carry the related gear wheel (74, 74') to mesh, besides with the main wheel (118, 118'), also with an internal gear (60) provided at the flywheel (56), in order to carry out a fast search of tape passeges. 
     In order to carry out fast searches in both the two directions without reversing the rotation direction of the motor, a satellite gear (94, 94') can be placed between the internal gear (60) and the gear wheel (74,74') only in one of the two rotation directions of the flywheel (56).

Abstract: The invention relates to the field of bookbinding machines, and in particular to a device controlling gripper members arranged to transfer books, magazines, and the like. 
     The technical problem to be solved was that of providing a simple and accurate form of mesh engagement of gear wheels, constituting power drives for said movable gripper members, with stationary racks arranged in a discontinuous fashion along the path of movement of said gripper members. 
     The solution to the problem is provided by positioning members (15, 16) projecting eccentrically from said gear wheels (4) and being adapted for engagement in an entry channel (18) located at one end of said stationary racks (14). Said entry channel (18) is made gradually narrower and has an oscillating portion (20) at that portion where said positioning members tend to move as the gear wheels engage with said racks (14).

Abstract: In high-pressure cleaning units with heating stages, i.e. with a possibility for circulating a partial flow of the forwardly pumped water through a constricted, heat-generating nozzle (74) in a return conduit to the pump's inlet side, the problem occurs that the entire water flow circulates at high pump pressure upon temporary interruption of ejection, which causes an inexpediently high heating of the water. By the invention, means are provided for sensing this situation and thus block the return conduit (70,72), so that the pressure tends to rise; in this way, however, the cleaning unit's ordinary bypass valve (12) will sense that delivery from the pump (P) is totally blocked, whereby it connects the pump in bypass state in the ordinary way through a non-constricted bypass connection (14). In this way, ejection can be interrupted temporarily without any substantial heat accumulation in the circulating water, and another advantage is that the ejection conduit itself is pressure relieved in the said situation.

Or, a single photodetector is positioned within the scanning region, and the scanning time from the start of scanning to the photodetector is detected by use of the photodetector. The initial position of scanning is controlled so that a predetermined number of pulses of the pulse signal having a predetermined period are input within the scanning time.

Abstract: An optical recording medium (10) including a thin film photosensitive layer (12) provided on a base (11) and having a protective layer (14), is disclosed. 
     The thin film photosensitive layer may vary between a low optical density state and a high optical density state when optical energy is applied thereto.

Abstract: An image sensing device has an optical shield (170), in front of an image sensing array (110) of the device, with a multi-aperture structure. The optical shield (170) has many shield elements (177) forming a grid-like or cellular structure. With such a structure, the solid angle of the field of view is almost the same for each sensing element (120) of a sensing array (110), resulting in the reduction of 'shading' effects and an improvement in signal or noise ratio. The distance (H) between the shield (170) and the array (110) can be reduced as compared with previous devices. The sensing elements (120) are not shielded individually, so the pitch of the shield elements (177) can be larger than that of the sensing elements (120), which makes it easier and less costly to fabricate the shield.
