Title: Manufacturing razors and shaving units for razors
IPC: B26B21/54
Filed: 1982-01-06
Abstract: A double edged strip (10) of blade metal is parted along a centre line and cropped to form two strips (16) each containing a series of spaced apart blades (17) connected by webs (18) to an elongate backing strip (19) of blade metal. Each strip is fed into a moulding machine in which a razor, or a shaving unit, or a blade-containing component of a shaving unit is moulded directly on to each individual blade (17). Each web is then parted to release the moulded razor, shaving unit, or shaving unit component, from the backing strip. Three modified processes are described in relation to Figures 8, 9 and 10 (not shown). <IMAGE>

Patent GB-2126963-A (GB)
Title: Air powered electrical vehicle
Inventor: BRIERLEY ROGER STUART
IPC: F02B1/04
Filed: 1982-01-20
Abstract: The invention is a method of producing electrical power in situ for use in the propelling of a moving vehicle through an air passage. This is achieved by streamlining the air of the air passage, then channelling the air through into a small cross-sectional area, by appropriate design of the vehicle, so that the air is accelerated to a relatively high velocity, substantially increased over that of the moving vehicle. The forward kinetic energy of the air stream is therefore increased in accordance with Bernoulli's theorem and is therefore capable of producing sufficient energy to not only overcome the air resistance of the vehicle but also most of the other drains on the power consumption of the vehicle, such as frictional forces. The kinetic energy of the air stream so induced is harnessed by placing an air turbine system in the path of the air stream, in an optimised position towards the rear of the vehicle. A generator is connected to the air turbine and the electric energy produced is fed to an electric motor, which propels the vehicle. This electrical energy could either be fed directly to the motor or first be transferred to a battery storage system. Whilst there are a number of air turbine systems that could be employed with this invention a special dual turbine arrangement is described in the request specification.

Title: Rotary mechanical seal
IPC: F16J15/36
Filed: 1982-03-10
Abstract: A seal assembly primarily for use with the stern bearing 4 of a ship comprises inner and outer face seal elements 6 and 7 mounted on a rubber body 8 for rotation with the propeller shaft 1. Any oil from the bearing 4 which leaks past the inner element 6, or sea water which leaks past the outer element 7, enters a void space formed by pockets 9 in the body 8. These pockets are separated by inclined vanes 10 which act as a centrifugal pump to expel the leakage material through a passage 11 in a seat 5. The assembly can also be used in other applications where the leakage material is corrosive or is likely to cause blockages. <IMAGE>

Title: Facilitating the handling and transport of articles in shop trolleys and baskets
Inventor: AIM GERARD
IPC: B62B3/00
Filed: 1982-04-13
Abstract: Pre-cut sheets are transported to the shops, shaped in the form of liners (30a to 30e) and stacked at the entrance to the shops in the form of piles (92) near to the lines of trolleys (95) or hand held baskets. Thus, customers can take hold of a trolley (1e) or hand held basket and introduce inside it a liner (30e) located at the top of the pile (92). The liners (30a to 30e) are made in such a way that they closely match the contour of the basket (8c). Each liner (30e) can be provided with one and the same advertising logo (100) and thus brought repetitively to the view of the customers in the shop. The invention makes it possible to transport articles more easily, especially to the check-out tills. <IMAGE>

Title: Apparatus for unloading radiation-sensitive film from a container and for conveying the film to a developing machine
Inventor: STAHL WERNER
IPC: G03D13/00
Filed: 1982-05-18
Abstract: At an unloading station 5, an X- ray film 22 is removed from a cassette 1 and is fed by rollers 6, 7 at a relatively high speed V1. Subsequently the film is fed to a developing machine 8 at a relatively low speed V2 by a pair of rollers 9, 10. The film is conveyed from the unloading station 5 to the developing machine 8 by means of a conveying system 11 comprising two pairs of rollers 12, 13 and 14, 15 which are driven in unison by a common variable speed drive 18. When a sensor 19 detects a leading end of the film 22 the rollers 12 to 15 are driven at a speed V1 which matches that of the rollers 6, 7, but are slowed to a speed V2 which matches that of the rollers 9, 10 when the sensor 19 detects the trailing end of the film. As illustrated, the system 11 can be arranged along a line between the unloading station 5 and the developing machine 8. Alternatively (Figure 2, not shown) it can be oriented at right-angles to and on one side of this line, with the drive (18') being reversed as well as having its speed changed when the sensor 19 detects the trailing end of the film. In this case, deflectors (23a, 23b) are provided to alter the direction of travel of the film appropriately. In a further embodiment (Figure 3, not shown) a selector device (25) can be provided to deflect the film from the unloading station 5 selectively to the conveying system 11 or to a film storage magazine (24). <IMAGE>

Title: Triphonic sound system
Inventor: TORICK EMIL L
IPC: H04H20/88
Filed: 1983-11-14
Abstract: A triphonic sound system in which three independent stereophonically related audio frequency source signals L, R and C are combined to derived three other audio frequency signals M, S and T which respectively comprise (L+1.4C+R), (L-R) and (-1.4C). In a preferred transmitter embodiment, useful in television broadcasting, the audio signals S and T modulate (14, 16) two quadrature-related sub- carriers of the same frequency to develop two double-sideband, suppressed-carrier signals, the frequency of the subcarriers being sufficiently high as to assure a frequency gap between the lower sidebands of the modulated subcarrier signals and the audio frequency signal (L+1.4C+R). The aforementioned signals, and a pilot signal having a frequency which lies within the frequency gap, are combined (12) and frequency-modulated onto a high frequency carrier for the purpose of transmitting the same to one or more remote receivers. The receiver (Figure 6) is operative in response to reception of the high frequency carrier to reproduce each of the audio frequency source signals L, R and C, and includes means (20) for reproducing conventional monophonic and two-channel broadcasts. <IMAGE>

Title: Mass-spectrometric method of analysis
Inventor: PUUMALAINEN PERTTI
IPC: G01N30/72
Filed: 1982-03-31
Abstract: The ionization chamber (2) of the ion source of the mass spectrometer is constructed in normal manner, applying a sufficiently open geometry so that the chamber contamination caused by the sample might be reduced. This however entrains the drawback that comparatively large sample quantities are required because part of the sample is pumped out from the ionization chamber without being utilizable. The said conflict can be eliminated by applying the method of the invention, when the ion source is provided with a plurality of separate ionization chambers (2), of which whenever desired any one can be rapidly selected for use, without disturbing the vacuum or ion-optical conditions in the mass spectrometer. The method is particularly well applicable when employing a gas chromatograph as sample input unit (4) in analysis situations where the mass spectra of sample components succeeding each other rapidly are measured, or where it is desired to record low intensity mass peaks after the occurrence at the same mass numbers of very powerful mass peaks in the preceding sample component.
