Abstract: The claims cover surface-modified inorganic oxide material (I) for chromatography and its prodn. in stages by: a) reacting an alkoxysilane (II) contg. an epoxide gp. in the omega-position to the Si atom with an amine or amide of the formula H-NRR' (III); R and R' = alkyl, aryl or acyl and R may also be H; in aq. medium to introduce an N-contg. gp. acting as ligand in chromatography into (II); b) reacting the prod. from (a) with an inorg. oxide material (IV) useful as chromatographic carrier; and c) thermal treatment and stabilisation of the reaction prod. from (b) after sepg. it from the aq. medium. In an example, 1.6 g glycidoxypropyltrimethoxysilane (IIIB) were dripped into a stirred soln. of 1.35 g NaOH and 0.9 g iminodiacetic acid (IDA) in 25 ml water in an ice-water bath. The mixt. was stirred 4 h at room temp. and overnight in a bath at 333 K, when IDA reacted with (IIB) to form a tert. amine (V). After cooling to room temp., the soln. was acidified to pH 3.5 with 25% HCl, then 5 g 'Polygosil 500-1525' (RIM) (IVA) were added. The suspension was degassed and stirred 3 h at 368 K, when most of the OH gps. on the surface of (IVA) reacted with the silane (V) to form siloxane gps. The modified (IVA) was filtered, washed and dried in vacuo, then heated 16 hr at 413 K and 20 Pa, when some of the unreacted OH gps. of (V) reacted with OH gps. on the surface of (IVA) and some with one another, forming siloxane gps. USE/ADVANTAGE - (I) is used in chromatography, esp. for sepg. cpds. of low or high mol. wt. It is biologically selective, stable and reproducible and has good chromatographic properties, high ligand density and can be produced easily and economically. It is useful e.g. for sepg. proteins, polypeptides and other biologically active cpds.

Inventor: BALLACH REINHOLD
IPC: B23Q3/155
Filed: 1993-01-14
Abstract: The tool gripper (3) can slide along the splined shaft (2). A follower pin (7) on the gripper engages in the track (6) of a drum cam (4) mounted on a parallel shaft (5) which is rotatable through a gear pair (18,19) by a hydraulic cylinder (15).

Title: Combination dual purpose bubbling bath
Inventor: FRENKEL WALTER
IPC: A61H33/02
Filed: 1993-03-12
Abstract: Besides the turbine (2), a compressor (3) is built into the housing (1) of a bubbling bath device. Consequently, it delivers either bubbling air at a high volume stream and low pressure or bubbling air at a low volume stream and high pressure. The two types of compressed air are fed, preferably via a double hose (5), to the feed line (6a) of the bubbling mat (6) and distributed there. The bubbles are produced, for example, either by bubble nozzles (6c) in the upper sheet of the mat, or by a perforated sponge rubber hose (6e) woven in between seating supports (6b). Since the indications for the massage bubbling bath and the other bubbling bath hardly overlap, a combination of the two principles is worthwhile. Symptoms from both lists of indications can be treated, simultaneously or consecutively, during a bath with one device. <IMAGE>
