Title: Process for improving the activity of silver-support catalysts.
IPC: C07D301/10
Filed: 1980-09-15
Abstract: Supported silver catalysts, which should have as high an activity as possible, are employed for the manufacture of ethylene oxide by oxidizing ethylene by means of oxygen or air. A process is described for improving the activity of supported silver catalysts which have already been used, in which the used catalyst is first washed with an inert liquid containing ammonia and/or aliphatic amines and 1 to 1,000 parts, per 1 million parts of catalyst, of cesium, rubidium or a mixture thereof is then deposited on the washed catalyst. The deposition is generally effected with the aid of an impregnating solution containing the cesium and/or rubidium compounds in a suitable quantity. This process makes it possible to improve considerably the activity of supported silver catalysts which have already been in use for the oxidation of ethylene by means of oxygen or air.

Title: Device for the production of coated products such as biscuits and the like.
IPC: A21C9/04
Filed: 1982-12-15
Abstract: A sandwiching machine is disclosed providing equal filler flow rates to nozzles in a rotational stencil and regular flow regardless of the speed of displacement of an associated conveyor passing by upstream and downstream cookie supply stations and a filler depositing station therebetween, the filler flow rate being regulated as a function of the speed of diplacement of the conveyor. The machine provides synchronization of the rotational speed of the rotational drives for the conveyor chains by means of a mechanical connection comprising clutches associated with a speed change device. The pressure of filler at the admission sides of volumetric pumps is maintained constant by means of a pressure regulator and accumulator. The feeding of the stencil cylinder is effected through two separate inlets. One inlet feeds filler into a hollow shaft fixed to the body of a valve member through a radial channel for communication through ports in the stencil cylinder with orifices in the rotational stencil. The other inlet carries filler into the delivery box at one end of the stencil cylinder between the latter and the hollow shaft. The ports may be selectively closed off by angular movement of the valve member.

Title: Brake actuation assembly.
IPC: B60T11/16
Filed: 1983-10-28
Abstract: A brake actuation assembly 10 having a master cylinder 12 attached to a stationary wall (14) of a vehicle and a power assist apparatus 16. Linkage 66 connects a movable wall 125 in the power assist apparatus 16 with pistons 64 and 68 in chambers 60 and 62 in the master cylinder 12.

Title: Melt dispensers.
IPC: B05C17/005
Filed: 1985-07-26
Abstract: A melt body (16) for a melt dispenser is disclosed which is particularly suitable for use in a hand held hot melt glue gun for use with rods of hot melt glue. The melt body including a melt chamber (17) provided with a series of fin elements (23) which define passageways terminating at an outlet (21). The fin elements increase in size progressively from an inlet (19) of the melt chamber to the outlet and ensure good transfer of heat to material to be melted. Edge surfaces of the fin elements provide surface portions of an opening adapted to receive the central portion of a rod as the rod is fed into the melt chamber. The shaping of the fin elements is such as to permit convenient manufacture by a die casting process. The spacing of the fin elements is selected so that melted material flows from the outlet when its viscosity has been reduced to an appropriate value to ensure good adhesive bonding. The arrangement permits improved consistency of heating the material and thus improved control of temperature of dispensed material. Also described is an improved hand held hot melt glue gun incorporation such a melt chamber, and incorporating a trigger operated feeding means (14).

Patent ES-8704685-A1 (ES)
Title: Analog-to-digital encoder and digital-to-analog decoder.
IPC: H03G9/02
Filed: 1985-11-16
Abstract: In the encoder an audio input signal is firstly given an adaptive pre-emphasis characteristic by a pre-processing circuit (16) and is then converted to a digital signal for transmission by a delta-modulator (22). In order to minimise the digital bit rate the delta-modulator (22) is rendered adaptive by deriving a step-size control signal in a circuit (18) responsive to the slope of the input signal, and applying the control signal to vary the step-size of the delta-modulator (22). The bandwidth of the control signal is limited to say 50 Hz by the step-size circuit (18) itself or a subsequent low pass filter (24) in order to render the encoder insensitive to random step-size errors. The slow response of the control signal is compensated for by a delay circuit (20) preceding the delta-modulator (22). The corresponding decoder comprises an adaptive delta-modulator and a circuit complementary to the pre-processing circuit (16). In order to keep the decoder as simple as possible it has no step-size derivation circuit. Instead, the step-size control signal is transmitted in conjunction with the main digital signal by way of an analog to digital converter (26). In the encoder a complementary digital to analog converter is followed by another bandwidth limiting filter to reduce the effect of transmission bit errors. The slow response of the decoder control signal is compensated for by transmitting the step-size information from the encoder with a time advance relative to the main digital signal.

Title: Composition for the production of white and coloured discharges on synthetic hydrophilic fibre material.
IPC: D06P5/13

Abstract: Ready-dyed dyeings with hot-fixed dyes on polyester fabrics have hitherto not been dischargeable with aqueous discharge print pastes since the discharging agent of a purely aqueous system cannot penetrate into the interior of the hydrophobic textile fibre. It is now been found that fast discharge prints can be produced on dyed polyester materials if the print pastes, in addition to hydrophilic solvents and discharging agents, contain hydrophobic copolymer mixtures.
