Abstract: Solid caffeine adsorbent which is made more selective to caffeine by a thin layer of a water-immiscible, caffeine-specific solvent. The caffeine is selectively extracted from the aqueous solution, leaving the solubles necessary for a good tasting beverage, by the solid adsorbent. Because the solvent is selective, the coated adsorbent likewise shows selectivity.

Abstract: This invention relates to the safety of ammunitions. The projectile of a cartridge has a base which houses a safety stop consisting of a transversely slidable valve. A device ensures that the valve cannot be released until the projectile has been subjected to a powerful acceleration. Another safety device very advantageously ensures that the pyrotechnical chain inserted in the base functions only when the pressure of the ejection charge has been able to release a sealing-block. In particular, the invention may be applied to infra red window releasing cartridges.

Abstract: © A cylinder block (10) comprises an upper block deck (18) disposed along whole the periphery of a cylinder-barrel section (12) to securely connect the cylinder-barrel section (12) with a water jacket outer wall section (14). The upper block deck (18) is located below the top of the cylinder block (10) and so positioned that its center (C) lies at the level of an uppermost part (16c) of the skirt section (16b) of a piston (16) which is at a range from TDC to 30 degrees relative to TDC. Additionally, upper and lower water jackets (22, 24) are formed at the upper and lower sides of the upper block deck (18), and communicate with each other through water holes (26) formed through the upper block deck (18). By virtue of the thus located upper block deck (18), the wall of the cylinder-barrel section (12) is effectively prevented from vibration due to piston slap, thereby greatly reducing piston slap noise emitted from the cylinder block (10).

Abstract: A liquid crystal display (1) comprises a layer (10) of cholesteric or smectic liquid crystal material contained between a front (8) and rear (7) wall. A pen 5 having a tip (16, 19) is caused to move across the front wall (8) causing an observable change in the liquid crystal under the pen tip. The change in liquid crystal material may be between its grand jean or planar state and focal conic state. This change may be caused by local pen tip pressure, heat, light or electric field. Erasure of observed information is by flexing of the liquid crystal layer (10). Alternatively heating and cooling, or an electric field may be used to erase the information. A resistive layer (2) covers the front wall (8) so that the instantaneous position of the pen (5) can be fed through bus bars (3,4) to a computer (6). This computer (6) compares the electrical version of an observed signature on the display (1) with a stored signature.

Abstract: This invention provides improved methods of investigating a body by nuclear magnetic resonance wherein nuclear magnetic resonance is preferentially excited in a slice of the body and the resulting free induction decay signals are detected in the presence of a magnetic field having first and second gradients (G y , G x ) in first and second directions respectively in the slice, the sense of the first gradient being periodically reversed. 
     In one proposed method two experiments are performed in which the phase of the first gradient (Gy) reversal is opposite and the detected signals from the two experiments are edited to obtain a set of signals, for Fourier transformation, occuring when the first gradient has one sense. Two such sets may be obtained, one for each sense of the first gradient, and the data obtained after Fourier transformation re-ordered and added. 
     In a second proposed method the second gradient (G x ) is applied only when the first gradient (Gy) has a given sense, and the free induction decay signals obtained when both gradients are present, and when only the first gradient is present, are separately processed. 
     In a third proposed method, the first gradient (Gy) is temporarily removed before each reversal of its sense, and the second gradient (G x ) is reversed while the first gradient is removed, the magnitude of the second gradient being controlled so that the time integral of the second gradient at the beginning of each period when the first gradient has a given sense is the same as at the end of the preceding such period, the free induction decay signals occurring when the first gradient has said given sense only being used for data retrieval.

Abstract: A lock includes a solenoid-operated striker unit (4) for capturing pin-bolts (9) of the shot bolt assembly (3) of a key-operable locking mechanism (1) of a hinged door (2). The pin-bolts (9) are captured within a keep channel-member (13) that slides up and down within a fixed channel-member (10) between an upper, release position in which slots (14) in the member (13) are in register with slots (11) in the member (10) and a lower, locking position in which the slots (14) are out of register with the slots (11). The member (10) is set perpendicularly to the general plane of swing of the door (2), the pin-bolts (9) being free to move into and out of the channel-member (13) through the aligned slots (11,14) when that member has been lifted into its release position by the solenoid (17) or a manually-actuable lever (27). A catch (19) latches the member (13) in this position untii released, allowing the member (13) to move to its locking position under spring action, in response to entry of the uppermost pin-bolt (9) into the striker unit (4). According to a modification a catch (31) is released by a forwardly-offset pin-bolt (32), and a keep member (30) slides up and down behind an apertured bar (29) rather than within a channel member. Also according to an alternative, a solenoid-lifted cylindrical keep-member (41) rotates about its longitudinal axis in admitting pin-bolts (44) to, and releasing them from, axially-directed slots (46) that capture the pin-bolts (44) when the member (41) moves downwardly under resilient bias.

Abstract: A method of determining the electrostatic charge on the surface (2) of an electrically insulating sheet material (3) -e.g. an electrophotographic film - is disclosed. The method uses the fact that an electrode placed against the opposite surface of a charged material will tend to have an opposite charge through induction. Thus an electrode (4) which may be part of the structure of an electrophotographic material is connected to earth through an electrical circuit (6). Two suitable circuits are described, one using the principle of a virtual earth amplifier and the other using a circuit arrangement which gives a measurable voltage which corresponds to the integral with respect to time of the current flowing through the lead (8) from the circuit (6) to the electrode (4).
