Abstract: Novel phosphoric acid derivtives represented by general formula (I):
      wherein X is a halogen and R is -(CH₂) n CH₃ (n = 0 to 3), or salts thereof are stable to non-enzymatic hydrolysis and are capable of specifically reacting with acid phos­phatase.

Abstract: The body (24) of a recreational vehicle (RV) is disclosed with a stowage compartment within the body interior but separated from the interior occupant space. The stowage compartment contains a tank (50) which serves as a waste holding tank for a water use sanitary toilet within the RV. The stowage compartment is partially disposed beneath the toilet (44,46) and has an opening (40) provided through the sidewall (36c) from the stowage space to the exterior. The opening (40) is displaced longitudinally relative to the toilet (44,46) such that when moving the waste holding tank (50) into and out of the stowage compartment, the tank travels in a generally horizontal arcuate path. The holding tank (50) is curved as seen in a plan view to accommodate the arcuate path. A track guide in the stowage compartment guides the path of the tank.

Abstract: A codeless digital method and apparatus for obtaining measured phase from a plurality of L2 signal transmissions. An intermediate frequency signal is derived by mixing (22) the L2 transmissions (16) with a local oscillator (32). That signal is hardlimited (28) and employed to terminate the count of a divide-by-32 counter (30) that is clocked by the local oscillator signal and initiated by a signal in synchronization therewith whose frequency is a fraction (40) of the local oscillator. The state of the counter (30) is applied to a four bit latch (38). The state of the latch, which effectively discards the most significant bit of the count, provides the measured phase of the L2 transmissions from which position can be obtained by reference to the satellite phase and delta range values derived therefrom.

IPC: F16D55/224
Filed: 1989-04-26
Abstract: The present specification discloses a friction pad assembly comprising a planar backing plate (2) to which a pad (3) of friction material is secured. To resiliently hold the pad assembly in position in a disc brake a resilient spring (19) is secured in the assembly. In known brakes the spring (19) projects beyond the profile and sides of the backing plate (2) and thus requires space within the overall design, available space being limited and critical to brake design. 
     The present invention provides a friction pad assembly (1) wherein an edge region (9) of the backing plate has two recesses (13) located symmetrically about a centre line (11) of the assembly with a resilient leaf spring (19) secured across each recess (13). In use, in a disc brake retaining pins engage against the springs (19) to hold the assembly in position. This pad assembly design thus minimises the required space by locating the resilient pad anti-rattle springs within the profile and sides of the backing plate (2), and by using the necessarily relatively short springs (19), the tendency for the springs (19) to be buckled or distorted, or affected by heat, is minimised.

Abstract: Le convertisseur amélioré (10) permet d'effectuer la conversion d'une tension à courant alternatif à fréquence variable à phase multiple ayant un degré élevé de bruit et produite par une source de tension à phase multiple et à fréquence variable en une tension à courant continu. Des impulsions de déclenchement pour un pont de redressement d'onde pleine sont générées par un filtre passe-bas (62) qui filtre un signal de sortie provenant de la source (12) de tension à fréquence variable et à phase multiple qui introduit un déphasage constant indépendant de la fréquence. Une forme d'onde rectangulaire est produite dont la fréquence est synchronisée avec des points de croisement zéro du signal de sortie provenant du filtre. Un compensateur de déphasage numérique (64) déphase la forme d'onde rectangulaire pour produire un signal de synchronisation ayant un déphasage fixe sur toute la plage de fréquence variable pour compenser le déphasage introduit par le filtre. Des impulsions de commutation pour des commutateurs dans le pont de redressement d'onde pleine (16) sont produites en traitant le signal de synchronisation résultant produit par le compensateur de déphasage numérique (64) pour obtenir un fonctionnement qui ne soit pas affecté par la présence de bruit dans le signal de sortie provenant de la source de tension à phase multiple (14).
