Patent DE-2160828-B2 (DE)
Title: Four-car raisable chained platform parking assembly - with two hoist platforms at minimum interval after lowering bottom platform
IPC: E04H6/18
Filed: 1971-12-08
Abstract: The assembly for dealing with four parked cars comprises raisable and lowerable hoist platforms one above the other on chains, freely cantilevered from the chains on both sides and with guide-arms to lead them on rails. The platforms can be raised and lowered only on one side of the chains, and entry is at the level of the furthest depressed top platform. Connection between platforms and chains is by a carrier device comprising carriers fixed to the chain, with stops on the guide-arms-carriers and stops being brought together by the chain's hoisting action leading to an increased interval between two platforms, the interval being reduced to min. after the bottom platform has been set down. Mechanisms may be assembled in rows for a series garage, with partitions, or one above the other with separate entries. Min. mechanical appliances are involved.
Patent DE-2212220-B2 (DE)
Title: Multiplier for variable frequency input signals - has ninety degree phase shift and uses specified power series for analogue multiplication
IPC: H03B19/06
Filed: 1972-03-14
Abstract: The frequency multiplier has a generator (17) to produce two 90 deg. phase-shifted sinusoidal voltages of the same frequency. A frequency multiplier circuit (1) multiplies these two voltages without altering their phase relationship. The analog multiplier circuit frequency multiplies according to two specified sine and cosine power series. Frequency multiplication according to these two power series can continue by any factor by repeating the multiplication stages. The advantage of the system lies in its being able to frequency multiply input signals whose frequency is continuously altering.
Patent DE-2227571-B2 (DE)
Title: Electrical brake lining wear indicator - has angle plates broken off by friction producing resistance change
IPC: F16D66/02
Filed: 1972-06-07
Abstract: The electrical indicator for motor vehicles is used to test brake linings. There are three angle plates (2, 3, 4) connected in a line to a common plate (1) with bolt holes drilled for brake linings. There are grooves (5, 6, 7) between the angle plates and long plate (1). The height of the upstanding limb increases from (8) to (10), so that if the lining is worn down as far as limb (10) so that it touches the friction surface of the brake drum, then the angle section breaks off at the grooves. Subsequent wear breaks off the shorter limbs too. The rear faces (13, 14, 15) form current branch paths, and are interconnected through the common plate (1), and to a display device with a voltage supply. Any change in resistance due to breaking off of one plate indicates the limiting wear of the lining.
Patent DE-2805453-B2 (DE)
IPC: G04C3/00
Filed: 1978-02-07
Abstract: An improved shock absorber for a watch movement and a method of making the same. The watch has a molded casing and a movement with a molded baseplate. A plurality of shock absorbers permanently mount the movement in the casing. Each shock absorber has a first portion molded in the watch casing, a second portion molded in baseplate of the watch movement, and an elastically deformable shock absorber connecting portion extending between the first portion and the second portion free of the casing and the baseplate. The method includes molding the first portion in the casing and molding the second portion in the baseplate with the connecting portion free of the baseplate and casing and the baseplate and casing free from one another.
Patent IE-S68845-B2 (IE)
Title: A mains powered alarm device having a rechargeable battery backup
Inventor: BYRNE MICHAEL
IPC: G01R31/36
Filed: 1996-04-15
Abstract: A smoke or fire alarm system is supplied from the mains or from vanadium pentoxide lithium batteries BAT1-3 charged through regulator U2 and protected by diodes CR8-10. A variable resistor VR1 sets normal voltage about 10% above nominal battery voltage. A battery testing circuit 15 draws 10msec current pulses from the batteries every 40 seconds through an LED and a resistor. If the battery voltage falls below a preset level, an alarm is sounded. During testing, a diode 13 reduces the output voltage from regulator U2 to prevent current flow to the batteries through resistor R4.

Granted: 1997-11-19
Abstract: The heat absorbing member formed by connecting to the bottom portion of the inlet header (1) with that of the outlet header (2) through the heat absorbing tube is installed so that the heat absorbing tube is located in the heating container (9), the heat absorbing tube (16) is comprised of a plurality of the down tubes (3, 4) and down tubes (5, 6) all with lower ends closed and connected under the inlet header (1) and outlet header (2) respectively, and the spiral tubes (7, 8) which connect to the top with the bottom portion of the down tubes (3, 4) and down tubes (5, 6), and the spiral tubes (7, 8) are the same length. <IMAGE>
Patent JP-H0370912-B2 (JP)
IPC: H01L27/148
Filed: 1983-03-03
Abstract: A multi-colour or other multi-level infra-red detector comprises at least one first detector element (10) formed in a first portion (11) of a lower body (11, 12, 13), e.g. of cadmium mercury telluride, and at least one second detector element (20) having different detector characteristics formed in an upper body (21) e.g. of cadmium mercury telluride. The lower body is divided preferably by ion-milling into at least two (and more usually three or more) portions (11, 12 and 13) separated from each other by gaps (14, 15) which are bridged by the upper body (21). Electrical connections to the second detector element(s) comprise the separate second (and further) portions (12 and 13) of the lower body and preferably include metallization layers (2 and 3) extending from the top to the substrate (1) on which the lower body (11, 12, 13) is mounted. The substrate (1) may be of insulating material, e.g. sapphire, or it may be for example a silicon CCD for processing signals from the detector elements (10 and 20).
Patent JP-3115338-B2 (JP)
IPC: B01D57/02
Filed: 1991-03-04
Granted: 2000-12-04
Abstract: A preparative scale multi-mode electrical separator, which is matrix-free and may be operated in both a batch mode and a continuous, flow-through mode is provided. It may be scaled according to the solution quantities which are to be processed. An internal cooling system whereby the process fluid is always in close proximity to a chilled surface assures an efficient heat dissipation during the separation and concentration processes and also allows the use of higher voltage gradients and shorter separation times than prior designs of electrophoretic separators. Electroosmotic mixing is reduced by providing internal, compartmentation of sample fractions, focusing is improved and focusing times are decreased. Different electrophoretic methods, including zone electrophoresis, isoelectric focusing, counterflow gradient focusing or electrodialysis, may be used with the separator. It may be applied to the purification of proteins, ions, and microorganisms, and for water purification. <IMAGE>
Patent JP-3325597-B2 (JP)
IPC: C12R1/19
Filed: 1992-02-26
Granted: 2002-09-17
Abstract: Processes for preparing polypeptides such as ricin A such that soluble polypeptide may be obtained. The pH may be adjusted during the process or the temperature decreased during the terminal portion of the cultivation, and yeast extract may be added to the growth medium during the cultivation. In the case of ricin A the pH is generally adjusted by lowering the pH from a first value such as 6.7 to a second value such as a value between about 5.5 and 6.7.
