Title: Clasped link garment fastener made from continuous strip - by cutting suitable lengths and attaching actuating lock
Inventor: ROESSELER KARL HEINZ
IPC: A44B19/62
Filed: 1973-08-09
Abstract: The clasped link fastener is supplied in closed condition in long lengths in coiled form. The fasteners are separated by punching out a length of clasp links at the separation area while the fastener strip is closed. The sliding lock is pushed into this slot and it engages with the clasped links of the fastener. The sliding lock opens the fastener and closes it behind it so that the end of the fastener is once again closed. This end is firmly closed by ultrasonic welding of the thermoplastics links. A piece of thermoplastics is inserted before welding and this is welded together with the links and a reinforced closed end is formed. The upper, open end is welded so that the two rows of links remain free but the tops are sealed. This method is used for continuous and rational production of clasp link fasteners in large quantities.

Title: Catalytic hydrogenation of carbon monoxide to hydrocarbons - using multiple catalyst layers in a sloping reactor
Inventor: FRANKE WILLY DR
IPC: C07C29/151

Abstract: CO is hydrogenated to hydrocarbons and their derivs. in a reactor contg. multiple catalyst layers and sloping down in the direction of flow at an angle of 0-50 (3-30) degrees to the horizontal, depending on the viscosity of the liquid products. High yields are obtained with a substantial increase in reactor output. The relation between number of layers and ratio of recycled (hot) gas and fresh (cold) gas can be pre-calculated. Liquid products draining from each layer run down the bottom of the reactor without blocking subsequent layers. Pyrophoric catalysts can be charged into and discharged from individual layers under an inert gas without dismantling the whole reactor. Number of catalyst layers (x) is 2-40 (4-30) and is related to ratio (y) between recycled and fresh gas by Y=.

Title: Automatically controlled microreactor - coupled to chromatograph having flow, pressure and temp. controls
Inventor: KOEGLER HELMUT DIPL CHEM DR
IPC: G01N31/10
Filed: 1974-05-24
Abstract: Experimental investigation of catalytic reactions is carried out in microreactor. Accurate metering of liquids is achieved by measuring their flow in control capillary with constant pressure drop. Gas is fed from cylinder to regulator with spring tensioned diaphragm, this giving an outlet pressure pi. There is a pressure backloading from this via a solenoid valve and manometer to the other side of the diaphragm and a similar signal is fed forward to two other regulators. The manometer controls opening of the solenoid valve and a purge valve. The spring on the first regulator has a screw adjustment. Gas then feeds forward via the regulator finishing with a pressure (p + p2). (P is press. at reactor; p2 pi). Top of capillary is at pressure (p + p1), so difference is controlled at (pi-p2). This allows flow to be measured. Liquid is injected into gas stream and combined stream enters heating capillary. This together with reactor plus regulator and sampler are in temp. controlled enclosure. The gas then enters the reactor which has 2ml. capacity and is filled with catalyst. Pressure across it is controlled so that outlet pressure is p. The reactor is of steel with electric heating and suitable insulation. The still gaseous reaction products than pass to sampler which on a time cycle which injects a sample into carrier gas stream which then enters separation column followed by detector and flow controller. The carrier gas can be taken from container via regulators if suitable, or an independent supply can be used. Regulator ensures that a constant pressure is maintained even when a sample is being injected.

The key is engaged with the locking insert by a relatively long lever which is provided in the front with latching lugs for the key. The other end of this lever is in contact with a roller. The combined latching and pressure point lever is also provided with a ratcheting locking insert which ensures that the key is readily withdrawn. The upwards movement of the front end of the lever is limited by a transverse lug. This combined lever is provided with a locking lug and, in conjunction with a locking lug in the housing, it prevents the key from being released from contact with the combined lever.

Title: Compressor for domestic waste - has die lowered into tannnk while operating a disinfectant spray
Inventor: BOCK WILLY
IPC: B30B9/30
Filed: 1974-06-26
Abstract: The waste compressor consists of a housing (10) in which a waste tank (13) is mounted. A die (11) is lowered into the tank by two screw spindles driven from a motor mounted in the base of the frame. A bracket (22) is attached to the side of the die.

Title: Child's chair adaptable to growth of child - has height adjustable standard seat acting temporarily as foot rest for extra seat panel
Inventor: HESS EUGEN
IPC: A47D1/00
Filed: 1974-08-08
Abstract: The chair is constructed basically as a standard chair wherein the seat (10) is detachably fastened to the chair frame whilst an additional seat panel (16) is mounted halfway up the back rest where it is possible for it to be suspended from the arm rests by means of side members.

Title: Stand for setting-up of poster - has two gable-roof-shaped stand sides at a slope towards each other
Inventor: BUBB MAX DIPL KFM DR
IPC: G09F1/10
Filed: 1974-09-16
Abstract: The stand sides (10) are at a slope towards each other and linked by means of a connecting arrangement (12) in the centre. The connecting arrangement (12) features a support (24, 20) for the lower edge of the poster (22) to be set up. The support (24, 20) serves for centring and by so doing, the upper edges (16) of the stand sides (10) apply themselves against the surfaces of the poster (22) under the effect of the spreading-out action exercised by the weight of the poster on the sides (10) of the stand. The connecting arrangement (12) consists of a butt strap which in the operating position extends horizontally from side to side.
