Title: Concrete mixer loading skip - has separate top and bottom compartments for cement sack and aggregates
IPC: B28C7/06
Filed: 1976-03-16
Abstract: The concrete mixer loading skip is in two parts, the first and bottom one accommodating the aggregates, and the second and top one the sack of cement, so that cement and aggregates are kept separate. The sack can be held by hooks on a shaft with a counterweight lever, so as to secure it while emptying. The cement and aggregates are discharged at the same time, but the cement does not interfere with the aggregates. Existing skips can be modified by adding a sack compartment to the to of the aggregate compartment.

Title: Hydraulic motor line leakage controller - has nonreturn valve in parallel with variable choke valve
IPC: F15B11/00
Filed: 1976-10-21
Abstract: A hydraulic motor arrangement prevents an uncontrollable load movement when there is leakage in the hydraulic fluid line between the controlling directional valve and the hydraulic fluid chamber of the motor acted upon by the load pressure. This hydraulic fluid chamber (1) is connected to the hydraulic fluid line (5) by a non-return valve (15) set so that it allows a flow of fluid into the chamber and through a variable choke valve (10) parallel to the non-return valve and controlled by an external setting force. The choke valve (10) is so controlled according to the operation of the direction valve (2) that, corresponding to the valve stem movement, it is opened from its nil position into the direction which produces an exit of fluid from the motor fluid chamber.

Title: Glue and gelatine prodn. from skin, bones etc. - by treatment in a first stage with caustic alkali soln. contg. a swelling inhibitor to give optimum degradation
IPC: C09H3/00
Filed: 1977-01-07
Abstract: Process comprises (1) treating the raw material with a 0.1-1.2 N caustic alkali (pref. NaOH) soln. contg. a swelling inhibitor, to give optimum degradation of the starting material, and (2) eliminating the alkali by washing with water, (3) neutralising to pH 5-8 with an acid and (4) sepg. the glue or gelatine by melting with hot water. The swelling inhibitor may be e.g. Na2SO4, K2SO4, (NH)2SO4, MgSO4, NaCl, KCl, NH4Cl and/or MgCl2.

Title: Piston lock operated by unique and master keys - has laminar pistons split by barrel axis and with indents for keys in alternate zones
Inventor: BOMBLED JEAN
IPC: E05B27/00
Filed: 1977-01-19
Abstract: The piston-lock is of a relatively simple construction and has a wide range of key to lock combinations, and all locks can be operated by a master key. The key has a laminar bit which has two longitudinal zones ie delineated by the longitudinal and central major plane. One zone is reserved for indents describing the master key, and the lock mechanisms are operable by either the master key or the respective individual key. The lock has a casing contg. a rotatable cylindrical barrel. The barrel includes the key-way and laminar radially mobile spring-loaded pistons at longitudinal intervals. The pistons have their major faces in radial planes of the barrel, and have square haunches and a segmental head. The key displaces the pistons to align their heads in the barrel periphery whence the barrel can rotate. The haunch of each piston is bisected by the barrel axis, and the appropriate half widths are notched to reciprocate the geometry of the key or the master key respectively.

Title: Dual purpose periscope system - has optical lens system for daytime use and image intensifier for use at night
Inventor: STAPLES JOHN CHARLES
IPC: G02B23/12
Filed: 1977-02-01
Abstract: The lens and the eyepiece system each contain at least one refracting element. The system transmits both in daytime and in nighttime operation a beam containing an image of the observed object. A mechanism for switching over between daytime and nighttime operation contains an optical system which directs the beam past the image intensifier in daytime operation through an auxiliary lens system. This lens system produces an image virtually in the same plane as that of the image of the nighttime intensifier, but displaced sideways in relation to it.

Title: Safety interlock for hydraulic brake servo - with staggered array of control valves with increasing throughput to reduce hysteresis losses
IPC: B60T17/22
Filed: 1977-03-11
Abstract: The brake servo has the input pedal pressure operating on the servo piston via a control spring and a set of control valves which connect the pressure reservoir to the servo. In order to provide a controlled servo action the valves are set to operate in sequence, and with increasing effect. This reduces the hysteresis effect and also prevents sudden, large braking forces if the pedal is depressed suddenly. The system enables emergency braking to be performed without sudden overbraking. The driver experiences a steady increase in the brake reaction force so that fine braking control is possible.

Title: Centring device for welding cylinder casings - which controls the position of the welding gun relative to the joint
IPC: B23Q35/36
Filed: 1977-05-20
Abstract: A centring device is provided for use in the longitudinal welding of gas cylinder casings by means of a welding gun movable along the longitudinal edges forming the joint in the casing. The device comprises a constant positioning assembly co-operating on one side with fixed abutments integral with the welding machine to enable the axis of the joint and the weld to be located in the same vertical plane. On the other side the assembly co-operates with control fingers which control the axial position of the gun relative to the vertical plane. The assembly activates the welding machine control system. The device functions automatically and enables casings to be welded consistently in an identical manner. Accurate centering is always achieved non-manually so that the weld rod is always positioned accurately in the joint.

Title: Procede de polymerisation de l'anhydride maleique
IPC: C08F2/06
Filed: 1977-07-22
Abstract: Procédé de fabrication d'anhydride polymaléique comprenant la polymérisation d'anhydride maléique dans du xylène comme solvant, dont la teneur en isomère ortho peut s'élever jusqu'à 99 %, avec du peroxyde de tert-butyle comme catalyseur de polymérisation.  Ce procédé est caractérisé en ce que le xylène est utilisé en mélange avec un solvant non réactif dont le point d'ébullition est compris entre 110 et 180 degrés C, notamment le monochlorobenzène. La présence du solvant non réactif conduit à l'obtention d'un produit (anhydride polymaléique) ayant une plus grande activité lorsqu'il est employé par exemple pour empêcher les dépôts de tartre dans des bouilleurs, echangeurs de chaleur et évaporateurs, par exemple les évaporateurs d'eau de mer, ou dans des installations de refroidissement industrielles, ainsi que comme intermédiaire chimique, comme inhibiteur de corrosion pour la protection de surfaces métalliques ou encore comme adjuvant pour détergents.
