Abstract: In a process for tanning and re-tanning hides, pelts, e.g pickled pelts having a pH between 2.0 and 3.5, wool-skins, fur-skins and leathers, they are treated with a tanning agent comprising zirconium, aluminium and chromium salts, the proportion of these salts, computed as the proportion of the oxides ZrO2:Al2O3:Cr2O3, bein 100: 5-50: 2-30, preferably 100: 10-20: 3-8, by weight. The tanning agent may be a mixed complex of Zr, Al and Cr salts obtained by heating and/or dehydrating, e.g. evaporating, spray-drying or roller-drying, an aqueous solution containing them.  According to Example 1, a powdered Al-Cr mixed complex is prepared and mixed with aqueous, technical zirconium sulphate, the mixture is heated to 80 DEG  C., then cooled and spray-dried to yield a powdered tanning agent, in which the proportion of the oxides ZrO2:Al2O3: Cr2O3 is 100: 14: 7. Tanning may be effected first with a zirconium salt, and then with aluminium and chromium salts, e.g. in the form of a mixed Al-Cr complex described in French Specification 1,244,477.  The tanning agent may be in the form of an aqueous paste, a highly concentrated aqueous solution, or a powder.  Specified zirconium salts are: zirconium sulphate, e.g. containing finely divided silica gel, and zirconium oxychloride containing sodium sulphate. Specified aluminium salts are the sulphate, chloride and acetate. Specified chromium salts are the sulphate, nitrate, chloride, acetate and formate, and chrome alum. The tanning agent may also comprise one or more of the following acids and their sodium salts: sulphuric, phthalic, sulphophthalic, sulphosuccinic, tartaric, formic, acetic, lactic, glycollic and citric.  Resulting leathers may be re-tanned or after-treated with a mineral, vegetable, synthetic or resinous tanning agent, then dyed, fatliquored, filled and dried.  A suitable synthetic re-tanning agent is described in U.K. Specification 443,967. The following types of leather may be prepared using the process according to the invention: full grain leather, suede leather, nubuk, white or dyed glove leather, white splits, white belt leather, sole leather, aniline dyed kid leather and shrunk leather.

Patent NL-7203353-A (NL)
IPC: A47C1/0355
Filed: 1972-03-14
Abstract: The chair back is reclined independently of movement of the footrest which is operated by a handle. Detents associated with the handle mechanism allow the footrest to be extended and retracted into any four positions including fully extended, fully retracted and two intermediate positions. As the back is reclined, the seat and arms which constitute a unit, are first tilted to a predetermined "bucketing" angle by the locking mechanism, forward rocking is inhibited then rearward rocking is also prevented by the novel locking mechanism. The locking mechanism mounts on the underside of the cam frame, between the cams and works off a torque tube that moves angularly about its long axis as the footrest is operated and which moves forward and upwardly and rotates angularly as the chair back is reclined. The seat and frame unit also move forwardly and upwardly as the chair is reclined. In the preferred form, the chair is a platform rocker; it may also be mounted on a swivel platform rocker base. The back is provided with tapered sleeves which fit over tapered tongues on the mechanism to allow the chair to be shipped knocked down, and then set-up. The footrest includes two sections which store one behind the other when retracted, then move to coplanar relationship as the footrest is extended to its first position to provide greater extension. The lazy tongs action of the footrest extending and retracting part of the mechanism is skewed to permit exposed front rail and/or high leg styling for the base. The design of the mechanism permits a particularly cushioning seat filling to be used.

Title: Edging tape having tassels prodn. - in which tassels are separated by lines of tying yarns which are automatically cut
IPC: D04D7/08
Filed: 1974-08-23
Abstract: A decorative edging tape comprises a support band from which hang a number of tassels which are held separated during prodn. by lines of tying yarns (e.g. elastic polyamide gimped yarns) passing around and extending between the tassels. To finish the tape it is advanced over a roller together with a strip of toothed material (e.g. card clothing on the roller surface) which immobilises the tassels and a sensor (e.g. a feeler arm) detects passage of the tassels over the roller and actuates e.g. an electromagnet to drive a cutter (e.g. an electrically heated) to cut the tying yarns between adjacent tassels. The tying yarns can be cut accurately, thereby eliminating a previously manual operation.

Title: Precursor for preparing water-oil fuels - prepd. from a mixt. of carbon, water and oil
IPC: C10L1/32
Filed: 1978-02-09
Abstract: Prodn. of a liq. fuel precursor which can be mixed with H2O and oil to produce a homogeneous fuel is carried out by first heating a 2-phase mixt. of carbon (pref. coke) H2O and oil (specific gravity 1) at 50-100 degrees C (pref. 70-100 degrees C) to evaporate the H2O from the lower phase (H2O + C) into intimate contact with the upper phase (oil+C). The residual liq. is then diluted with 20-60 wt.% of a light oil to form a homogeneous mixt., from which solid C is then sepd. The resulting liq. is then burned in the presence of O2, the flame is quenched by cutting off the O2 supply, and the liq. product is recovered. Fuels produced using the precursor can be used, e.g., for steam or electricity generation. A mixt. of 40% oil (11,000 gal/g), 30% precursor (5500 cal/g) and 30% H2O (0 cal/g) is stated to have a calorific value of 10,766 cal/g instead of the expected 6050 cal/g.

Title: Concentrated foaming agent for cellular concrete mixture - is pumped into water mixing vessel in controlled ratio to diluting water supply
IPC: B28C5/38
Filed: 1981-08-06
Abstract: Hoppers with transport worms supply dry cement and aggregate respectively to a trough (11) provided with a water supply and with a further worm to transfer the watery mixture to the inlet end of a second trough (13) connected with (47) a foaming agent supply system (30). A further worm (14) in this trough (13) transfers the final mixture to a pump (18) with outlet (19) to the mould pouring station. The system (30) contains a supply vessel (23) for concentrated aqueous foaming agent and a variable (32) pump (26) feeding this (27,20,25) to a mixing vessel (28) connected to a water supply line (29) with flow meter (31) controlling (32) the pump (26). A pump (36) connected (33) to the vessel (28) passes the mixed agent to one side (34) of a branch connection (35) whose other side (41) connects to an air pump (45), the joined flows passing (44) to a foam forming vessel (46) connected (47) to the trough (13). The arrangement provides accurate control of the dilution ratio of the foaming agent, thus ensuring homogeneity of the cellular concrete which is of particular importance when manufacturing low-density products.

Title: Gamma-globulin mfr. for intravenous injection to treat infections - involves treatment with pepsin or uropepsin enzymes at neutral ph to reduce anti-complement side-effects
IPC: C07K16/12
Filed: 1982-07-15
Abstract: Prodn. of gamma-globulin, suitable for intravenous injection, comprises treating the gamma-globulin with the enzyme pepsin or uropepsin, at a pH of 6.0-7.5, pref. 6.5-7.0. Pref. both the gamma-globulin and the enzyme are of human origin. Therapeutic agents contg. a gamma-globulin and human uropepsin or uropepsinogen as stabiliser are also claimed. Pref. 0.01-5%, esp. 0.1-1%, of enzyme is used. Used for prophylactic and therapeutic treatment of bacterial and viral infections by intravenous injection of gamma-globulin. Gamma-globulin purified by known methods produces serious side-effects (sudden reduction of blood pressure, chilling, vomitting, pyrexia, cyanosis and shock) when administered intravenously. Treatment of the purified gamma-globulin by known methods (e.g. treatment with proteolytic enzymes (pepsin)) to avoid the side-effects due to complement activation give a product with a very short half-life. The present treatment, with pepin or uropepsin at neutral pH, gives a product suitable for intravenous injection, with a long circulatory half-life and with retention of the opsonic activity of the gamma globulin.
