Patent EP-0338351-A2 (EP)
Inventor: BIRKE JOSEF
IPC: A43B7/28
Filed: 1989-04-08
Abstract: To produce custom-made orthopaedic shoes, a plaster cast (2) is first taken in the correction or bedding mould of the rear foot of the foot sole of the patient. Then the bedding mould (1.1) required is shaped to a rough last (1). Subsequently, a plastic film (4) is drawn over the sole and side surfaces of the last (1) and a foot bed (13) and cut in the manner of a sole with a rear cap (4'). A trial shaft (5) is pulled over the last (1) and lasted and glued to the plastic film (4), so that a trial shoe is produced. Under this, a heel (6) is fastened. After trial by the patient, the last (1) is if necessary corrected. Finally, on the corrected last (1), with the aid of a prefabricated leather shaft, the size and shape of which are determined using the trial shaft (5), the custom-made shoe is finished. The time-consuming transfer of the last shape to the leather with the aid of paper templates etc. is eliminated completely. Use can be made of shoe parts, in particular insoles (3), front and rear caps, leather shafts, outsoles, heels (6), eyelets, shoelaces etc., which are prefabricated in series production and matched to one another. As a result, high rationalisation, excellent fit and modern fashionable appearance are ensured. <IMAGE>

Abstract: One of the routes to prepare optically active 2-(4-aryloxphenoxy)propionic acid ester herbicide is to couple optically active 2-(4-hydrophenoxy)propionic acid esters with halogenated aromatic or heteroaromatic compound. Conversion of the optically active 2-(4-hydroxyphenoxy)propionic acid ester into the acid salt prior to the coupling step effectively prevents the racemization that unexpectedly occurs otherwise.

Abstract: A cesium oscillator includes a cesium beam tube (115), and an oscillator circuit (111, 113) which generates an oscillation signal of a frequency to be supplied to the cesium beam tube. A frequency control circuit (151, 117) including a sweep circuit and a feedback loop circuit continuously varies the frequency of the oscillation signal. The frequency of the oscillation signal is continuously varied two times when the frequency of the oscillation signal is to be adjusted. A hold circuit (131) holds the highest signal level of the resonance signal supplied from the cesium beam tube when the frequency control circuit continuously varies the frequency of the oscillation signal first. A control circuit (121, 141) controls the frequency control circuit so as to stop continuously varying the frequency when a signal level of the resonance signal obtained by continuously varying the frequency of the oscillation signal by the frequency control circuit for the second time becomes equal to the highest signal level held by the hold circuit.

Abstract: The application refers to is a system for transferring audio and/or video information via an information carrier e.g. DAT, CD or CDV. In the R-W subcode channel of the CD-signal textual information about the audio and/or video signal has been recorded. This information is divided in packets. Packets containing information of different categories are interleaved. After reading the information from disc the packets of a selected category are separated from information read. This system of transferring additional information allows the use of an own packet category for each of a number of different languages, so that a user can select language with which he is familiar at most. 
     Further, menu information, comprising coded menu text lines and commande codes, are recorded in the R-W subcode channel for interactive control of the read-out of the audio and/or video information or the control of other connected devices.

Abstract: A process for manufacturing fluid cracking catalysts by an  in situ  procedure. Sodium zeolite Y (synthetic faujasite) is crystallized in pores of a physical mixture of preformed, highly porous precursor microspheres, one portion of the microspheres is composed of metakaolin and the other portion of the mixture of microspheres being composed of kaolin calcined to undergo the exotherm (the latter sometimes being referred to as spinel calcined clay or simply spinel). In particular, by the present invention the precursor microspheres have enhanced porosity (e.g., 0.3 to 0.5 cc/g as measured by mercury porosimetry) and are obtained by spray drying a slurry of hydrous (raw) kaolin clay which is characterized by presence of a major amount of large (plus 2 micron) kaolin stacks, which when spray dried, result in microspheres having the desired high content of macropores in which zeolite Y can grow. Relatively high levels of metakaolin containing microspheres are used in the synthesis.
