Title: Cooling tower
IPC: E04H5/12
Filed: 1979-04-12
Abstract: A cooling tower has a shell 1 which is tapered upwardly in the crown region. The angle  alpha  between the tangent to the internal contour and the vertical in the upper part 6 of said crown region of the shell is chosen to be not smaller than results from the following equation:   <IMAGE> in which is  alpha  is the angle in question, g is the acceleration due to gravity,  rho i and  rho a are the gas densities inside (i) and outside (a) of the cooling tower, z is the vertical coordinate, d0 and d(z) are the diameters of the internal shell contour at the level z = o and z, respectively, and w0 is the gas velocity at the level z = o. For example the internal shell contour in the tapered crown region may be arcuate and concave. The cooling tower designer thereby gets a means to provide for shell contours which for all sizes of cooling towers on the one hand safely prevent cold air penetration and on the other hand ensure a minimum of draught losses in operation of the cooling tower. <IMAGE>

Patent GB-2055945-A (GB)
Title: Safety belt stop
IPC: A44B11/08
Filed: 1979-08-03

The stop comprises a body (10) in which a slide (30), carrying a knurled roller (50) is slidable between a clamped position in which the roller engages the run (6) of the belt thus clamping the stop (9) to the belt, and a released position in which the roller (50) is free to rotate and the stop (9) is therefore slidable along the run (6) of the belt.
Patent GB-2030208-A (GB)
Title: Permutation lock
IPC: E05B37/12
Filed: 1979-08-24
Abstract: The permutation lock has at least two blocking devices each containing a blocking disc 20 provided with an engagement opening 50 cooperating via an indexing device with a selection disc 14. Each engagement opening 50 is engaged by a blocking tongue 48 which is arranged on a blocking slide member 46 spring biased against the blocking disc 20. The blocking slide member 46 has a shoulder 62 which cooperates with an operating slide member 68. When the operating slide member 68 is in the locked position, the shoulder 62, when the blocking tongue 48 is displaced from the engagement position 50 engages a recess 64 of the operating slide member 68. When the operating slide member 68 is in the unlocked position, the shoulder 62 rests against abutment 66 of the operating slide member 68 thereby preventing the blocking tongue 48 from leaving the engagement opening 50, so that the blocking disc 20 is prevented from turning while a new opening code number can be selected by rotating the selection disc 14 relative to the blocking disc 20. The lock is intended primarily for briefcases and suitcases. <IMAGE>

A frame comprises circular elements (20) formed by at least two segments (21, 22) whereof one of the segments (21, 22) is intended to install the thin edge of the lens and a nose strap (24) installed with due regard for the required face angle. A refraction measuring method comprises focusing a sight tube (37) at an object (44), placing an ophthalmic lens (43) under test between the sight tube (37) and the object (44), making the center of the entry pupil (41) of the sight tube (37) coincide with the center of rotation of the lens (43), turning the lens (43) about its center of rotation until thickness is obtained corresponding to the distance from the front surface of said lens to the object (44), measuring the lens power by the method of compensating the lens power of the lens (43) using a reference lens (45) until a sharp image of the object (44) is obtained in the focal plane of the eyepiece (39) of the sight tube (37), and subsequent determination of refraction by the lens power so measured. <IMAGE>
Patent GB-2227107-A (GB)
Title: Equipment for electronically storing data
Inventor: SLOAN ROBERT COLIN
IPC: G06F21/32
Filed: 1979-10-05
Abstract: In order to make the stored data secure, the equipment comprises one or more sensors (a, b, c) which sense a predetermined characteristic of an authorised user and cause erasure of the stored data if this characteristic is absent e.g. for more than a predetermined time. For example sensor a senses a life function such as heart beat, sensor b compares a spoken word with a predetermined word spoken by the authorised user, and sensor c compares a code with a predetermined code associated with the authorised user. In the case of sensor a, a timer 12 causes erasure of data stored in a RAM 15 if the life function is below a threshold level for a preset time. In the case of sensors b and c, the timer 12 causes erasure of the data if successful comparisons are not regularly performed. In the case of sensor c a predetermined number of unsuccessful comparisons causes erasure. Furthermore, a sensor 17 is sensitive to breaking- open of the equipment, to cause erasure of the data. <IMAGE>
Patent GB-2035828-A (GB)
Title: Apparatus and method for desorption of gas from a liquid
IPC: B01D19/00
Filed: 1979-11-22
Abstract: The apparatus comprises a chamber 11 from which a liquid is withdrawn by a pump 21 and returned to the chamber 11 through a line 13 after passing through an external system (not shown). An aspirator 15 is powered by a part of the liquid delivered by the pump and has an inlet 18 which draws liquid from the chamber 11. The aspirator is arranged to deliver the liquid through a vertical outlet which opens into the chamber 11. The rate of flow through the aspirator 15, effecting desorption of gas in the liquid, is thus not limited to the rate of flow through the external system. <IMAGE>

Patent GB-2045924-A (GB)
Title: Spectrophotometer
IPC: G06G7/48
Filed: 1980-02-22
Abstract: A dual beam ratio recording spectrophotometer has signal processing circuitry for determining the transmittance of a substance. The signal processing circuitry has a bandwidth which is dependent on the magnitude of the radiation passing through a reference cell and includes control logic circuitry 7 which produces a pulse on line m whose width is proportional to the square of the magnitude of the radiation detected when the beam passes through the reference cell. A sample and hold circuit 22 whose sample time is controlled by the pulse on line m samples the output of an integrator 20 which produces at regular intervals a signal representative of the transmittance of the substance. Thus the response time of the sample and hold circuit and hence the bandwidth of the signal processing circuitry depends on the magnitude of the radiation passing through the reference cell. <IMAGE>

Title: Improvements in heat treatment of liquids having a significant gas loading
IPC: C12H1/18
Filed: 1981-01-20
Abstract: In the heat treatment of liquids with a significant gas loading, e.g. the pasteurization of heavily gasified beer, it has hitherto been felt necessary to provide recirculation of insufficiently treated liquid from the outlet of the plant where the liquid is cold, rather than from the hot section, because of the risk of gas breakout. In accordance with the present invention, there are provided two feed pumps 17 and 18 in series and a diversion valve 15 located in a line 5 between the heating section 4 and the holding section 6. The diversion valve 15 diverts insufficiently heated liquid via a line 16 to a point between the pumps 17 and 18 at which the pressure is sufficient to prevent gas breakout at the temperature concerned. A bleed line 19 is provided to give recirculation round the first pump 17 when it is operating under conditions of no forward flow during diversion. <IMAGE>
