Abstract: The two portions (1,20) of casing are in the form of hollow half-cylinders with semicircular ends (3,4). Equidistant from these on one portion (1) are cantilevered elastic catches (5,6) of similar shape and rectangular section with bars (7,8) projecting at right angles from their centres. Recesses (11, 12) are formed in the ends (9,10) of the catches (5,6) beyond the sloping surfaces (13,14) of the bars (7,8). Stops (15,16) with ramps (17.18) are spaced (x) away from the catches (5,6) on the side wall (2). When the portions (1,20) are engaged the catches (5,6) slide between elastic counterparts (25,26) on the other portion (20) until the bars (7,8) enter holes (27,28) and the cantilever ends (9,10;29,30) are held against the stops (35,36;15,16).

Abstract: An air conditioning system for a vehicle has a coolant circuit with high and low pressure sections. To prevent overpressure, a venting valve dumps coolant into a low pressure store (11). On pressure reduction this stored coolant is valved back into the system. The dumping valve and the re-entry valve (13,14) are integrated into the same assembly for space saving and to reduce pipework. The size of the storage reservoir depends on the type of coolant used and the size of the system.

Abstract: The mould or core housing (1) filled with foundry sand and binder is cured by means of a reagent which is vaporised. The reagent is introduced into the housing (1) from a cylindrical container (7) using a propellant flow delivered from a pressure source (15). The reagent is conveyed by a metering pump (27) into the container (7), in which a subatmospheric pressure produced by a vacuum pump (33) prevails. Due to the subatmospheric pressure, the reagent vaporises more rapidly than at atmospheric pressure. It is thereby possible to use reagents with a high boiling point, as a result of which the curing of the moulds and cores can be effected more economically and with less smell.

Date Oct. 5, 1989.The chromic anhydride contained in soluble form (chromic acid) in exhausted, polluted chromium plating baths is recovered by alkalizing the exhausted chromium plating liquid to a pH comprised between 3 and 7 at a temperature of 70 DEG  C. with a commercial sodium hydroxide solution, keeping the mass in reaction at this temperature for an hour and filtration separating the precipitate obtained. The filtered solution having a specific gravity of 1.25 kg/l, contains CrO3 (22% in weight) which is then reduced with sulphur dioxide to obtain a solution containing basic chromium sulphate and sodium sulphate, suitable for use as a tanning bath; in this manner pollution is avoided and the waste chromium is exploited.

Abstract: Ionisation current, flowing in an earth return path from a cylinder in which ignition has occurred, is measured. The current is passed through a bandpass filter, tuned to pass frequencies which occur during knocking, and the filtered current is plotted against crankshaft angle. At a given time, when the unfiltered ionisation current reaches a threshold value (Is), a window is initiated during which the filtered signal is sampled over a fixed crankshaft rotation angle (delta-alpha F). Provided that the unfiltered ionisation current remains above the threshold value throughout a given period following initiation of the given crankshaft rotation angle, then the filtered ionisation current (I') throughout the period of the given crankshaft rotation angle is investigated. It may be determined whether the peak signal value has exceeded a critical value.

Abstract: Optical-recording medium having a light-transmitting substrate layer. 
<??>CDs are such recording media, on which data are stored in so-called pits, that is to say depressions in a light-reflecting layer following the light-transmitting layer. In the case of magneto-optical discs, data are stored in a magneto-optical layer by magnetising in the one or the other direction of magnetisation. For reading the data stored in this way, use is made of the Kerr effect, which produces a measurable rotation of the polarisation plane when a linearly polarised light beam is reflected at the magneto-optical layer. Although both recording media - CD and magneto-optical disc - already have a high storage capacity, a considerable increase in the storage capacity is of great benefit, in particular for computer applications and as a video disc. 
<??>In order to increase the storage capacity considerably, the light-transmitting substrate layer (1) is followed by a light-reflecting magneto-optical layer (2), in which data can be stored on the one hand by magnetising and on the other hand by means of depressions (3), so-called pits. The light-transmitting substrate layer (1) may also be followed by a partially transmitting magneto-optical layer (2) without pits (3), which is then followed by a light-transmitting layer (10). In this or a following layer (11), data can be stored by means of pits (3).

Abstract: The present invention suggests the introduction of an additional protocol element for a preventive display of transmission costs in the case of Internet and on-line services, at least for the transmission of larger quantities of data, such as, for example FTP files, sent by the provider, which can, at least, contain the scope of the data in the pending transmission, as well as other price criteria, optionally, which is recognized as such by the nodes (routers) that are involved in the transmission, and which may be expanded by its own proportional transmission prices, such that, ultimately, in the recipient's PC, on the browser for example, an evaluation of the protocol element, with a display of the costs, accordingly, appears on the screen, after which the subscriber can institute a transmission or disrupt it and optionally, take additional measures, such as, for example, activating the automatic instigation of the transmission at a later, more favorable time from the standpoint of costs. In particular, the introduction of the protocol element for all pending transmissions of data, including, for example, HTML pages, makes sense as an option that affords protection against the senseless delivery of large numbers of illustrated pages, especially in cases of rapid Internet access.
