Granted: 2001-12-25
Abstract: A scaffold coupler is actuated by an over-centre lever mechanism. The scaffold coupler, which is of resilient plastics, includes a hand lever 13. which is hinged to a jaw 12 that closes upon a base member 11 to clamp tight a scaffolding tube 15. A hook member 14 hinged to the lever 13 engages with a lip 19 of the member 11 so that depression of the lever 13 urges the jaw 12 hard onto the tube 15 and actuates the clamping mechanism by pulling the hook-hinge 22 through 'over-centre' alignment with the lever-jaw hinge 21 and the hook-lip engagement 'hinge' 23. The base-jaw surface 17 subtends more than 180 degrees to snap fit with the tube 15, and opening of the closure jaw 12 is limited by a projection 20 (or otherwise, Figure 7) for support of the tube 15 (Figure 2). Closing of the jaw 12 may be tripped by entry of the tube 15 (Figure 6), and the jaws may be abrasive-surfaced (Figure 5) to improve grip. The lever 13 may be selectively locked in the actuated. condition (Figures 19 to 24), and other configurations of over-centre lever mechanism are possible (Figures 25 to 29). Right-angle, swivel and sleeve couplers (Figures 9, 10-13, 17-18) include two over-centre mechanisms, whereas a putlog coupler (Figures 14-15, 16) includes one, with the second pair of jaws actuated by one or more levers 63 that bear on the tube 62 clamped by the first pair.

Title: Pipe coupling
Inventor: STRAUB IMMANUEL
IPC: F16L23/04
Filed: 1991-03-18
Granted: 1994-08-23
Abstract: The pipe coupling has a cylindrical housing which is split in the longitudinal direction and has inwardly bent end walls and a steel insert sheet of analogous design bridging the housing gap.  With the aid of a closure with  tensioning  screws,  the  housing  can be constricted in the manner of a pipe clip, the sleeve being compressed in the circumferential direction and being brought to bear on the pipes to be sealed off. The closure is offset in the circumferential direction in relation to the housing gap and the end section of the housing projecting through the region of the tensioning screws is overlapped by a slideway anchored on the other end section. By this means, the dimensional stability is increased without increasing the wall thickness or the constrictability of the housing is guaranteed despite increasing the wall thickness.

Filed: 1992-03-27
Granted: 1996-12-10
Abstract: A selective calling receiver includes a decoder having a reference clock oscillator and a CPU having a CPU operating clock oscillator.  The decoder includes a timing control circuit for generating a timing signal in synchronism with a synchronizing signal contained in a POCSAG signal and a BCH error correcting circuit for extracting a message code from the POCSAG signal. If the CPU is supplied with a message code from the decoder when no timing signal is inputted from the decoder, the CPU stores the message code in RAM in the CPU or a buffer memory area of external RAM connected to the CPU. In this case, the CPU operates with a first clock signal generated by the reference clock oscillator. When the CPU is supplied with the timing signal from the decoder, the CPU reads the message code from the RAM or the buffer memory area and processes the message code with a second clock signal generated by the CPU operating clock oscil-lator and the second clock signal has a frequency higher than the frequency of the first clock signal.

Title: Frozen desserts with flavour strands
Inventor: KORTSCHOT CORNELIS
IPC: A23G9/28
Filed: 1992-10-22
Granted: 1996-05-14
Abstract: A frozen dessert such as ice cream, and a process for manufacturing same, are described.  The chocolate or other flavouring composition is injected into the stream of semi-frozen dessert in the form of a pumpable semi-liquid which freezes into ribbons or strands upon contact with the dessert. The fat and oil fractions of the flavouring composition are formulated so that the composition can be conditioned from a solid or semi-solid paste into a high-viscosity semi-liquid composition which can be pumped with a positive-delivery pump, and so that as soon as the composition is cooled a few degrees by being in direct contact with the ice cream, the viscosity rises rapidly and the composition once again becomes a solid or semi-solid.  The conditioning can be accomplished in one of at least two ways.  Firstly, the flavouring composition can be conditioned from the temperature at which is is a semi-solid paste, to a few degrees above that temperature.  Secondly, the flavouring composition can be fully melted at an elevated temperature, and then supercooled to below the temperature at which it would be a semi-solid paste under steady-state conditions, agitating it to prevent crystallization.  The preferred formulation for the flavouring composition is 46.61% fractionated and partially hydrogenated vegetable oils, 32.95% sucrose, 20.04% cocoa powder, and 0.40% lecithin.  The vegetable oil composition is 91.8% Oleic, Stearic and Palmitic fractions, namely 10.8% Palmitic, 7.3% Stearic, and 74.7% Oleic.

Title: Method for quick charging of rechargable batteries
Inventor: AL-ABASSY ISSAM
IPC: H02J7/00
Filed: 1992-05-30
Granted: 2002-11-05
Abstract: A device for quick charging of batteries, whereby the charging current of the battery is directed in constant current impulses. Several charging current strengths of varying strengths are brought into effect, depending on the respective charging condition of the battery, by clock impulses. Assigned to each charging current strength is a battery-specific zone in the electrochemical voltage gradient U=f(t), whereby the individual zones are indicated by voltage set values. The voltage zone assigned to each charging current strength is so chosen that in passing through this zone, no heating or gassing occurs. Thereby, use is made of the fact that the battery at the beginning of the charging can accept a very high current. The charging condition of the battery is measured in each impulse pause, stored and compared with the voltage set value. Where there is a variance, the set-current value assigned to the zone is correspondingly adjusted.

Abstract: A method for stabilizing an agent for contact lenses containing a proteolytic enzyme by adding a surfactant to a solution containing an effective amount of a proteolytic enzyme, the production of a lyophilized agent for contact lenses containing a proteolytic enzyme, which comprises subjecting an aqueous composition containing a proteolytic enzyme to a lyophilizing treatment in the presence of a surfactant, and a lyophilized agent for contact lenses which contains a proteolytic enzyme and a surfactant.  The method of the present invention enables stable preservation of a proteolytic enzyme in a liquid form.  In addition, cleaning, sterilization and preservation can be simultaneously performed with a single solution, wherein an efficient removal of soil is achieved by only immersing contact lenses in the agent in a solution state.          Accordingly, the agent of the present invention is advantageously used with ease by simple handling.  The method for producing the lyophilized agent of the present invention enables stabilization of a proteolytic enzyme during preparation into a lyophilized formulation.  Furthermore, the lyophilized agent of the present invention permits the proteolytic enzyme to remain stable and is extremely superior in solubility.  When preserved as an aqueous solution, the stability of the enzyme can be maintained over a long period of time due to the action of a surfactant contained therein.
