Title: Improvements in ornaments having a half tone visual effect and a method of making same
IPC: G03F7/00
Filed: 1979-01-12
Abstract: An ornament of the type comprising a sheet of material with a metal face with a dot picture etched thereon is made by a photoresist-etch method. The photoresist mask is formed by enlarging the desired pattern on a smaller scale broken up into a matrix of dots of constant density but varying size so that the lands between even the largest dots is enlarged in width so that the etching does not completely undercut the lands. The metal surface can be plated e.g. with gold or silver, and have a polished or matt finish e.g. of anodized aluminium.

Title: Frequency synthesiser
IPC: H03L7/197
Filed: 1979-06-25
Abstract: In a digital frequency synthesiser the output of a voltage controlled oscillator 1 is divided down to a reference frequency by a variable divider 2. A reference frequency oscillator 3 has its output fed to a phase/frequency detector 4 together with the divided frequency. The detector output is used as a control signal, via a loop bandpass filter 5, for the v.c.o. To obtain fractional division ratios the divider is switched between two adjacent division ratios at a rate higher than the bandpass frequency of the loop filter. Switching is effected by a rectangular wave the mark/space ratio of which is controlled by a variable mark/space ratio pulse generator 8. The generator output is added to the least significant digit output of a binary encoded programme switch 6 used to control the frequency divider 2. Fine adjustment of the oscillator 1 output is obtainable by adjustment of the mark/space ratio. The oscillator 9, instead of being fixed, may have its centre frequency variable in a predetermined or random manner. <IMAGE>

Title: Image reproduction equipment
IPC: H04N1/387
Filed: 1980-07-23
Abstract: To record on a single sheet (9) both a picture image and alphanumeric characters, each character to be recorded is stored (24) in the form of signals representing a multi-column pattern of dots which make up that character. Signals derived in synchronism with the scanning of successive lines on the recording sheet are applied to circuits (19, 20, 23, 25) to derive a column address signal for the character store (24), which is also addressed with a data signal representative of a selected character (32). In this way, signals corresponding to a selected column of the required character are taken from store and are applied to a selector circuit which also receives the picture signals and applies either the picture signals or the character signals to the recording head. <IMAGE>

Title: Production of alkyl methacrylates
IPC: B01J23/31
Filed: 1981-03-16
Abstract: A process for the production of alkyl (especially methyl) methacrylates from propylene is provided which involves fewer steps than hitherto. The propylene is catalytically hydroformylated to isobutyraldehyde and then converted by oxidative dehydrogenation to methacrolein; oxidative esterification of the latter in the presence of alkanol gives alkyl methacrylate. The preferred catalyst for oxidative dehydrogenation comprises optionally doped  gamma -phase bismuth molybdate and for oxidative esterification comprises optionally doped molybdenum oxide. In an alternative route, alkyl isobutyrate is converted by oxidative dehydrogenation to alkyl methacrylate in the presence of optionally doped  gamma -phase bismuth molybdate.

IPC: A23G4/12
Filed: 1981-12-14
Abstract: A confectionary product consists of a basic confectionary composition and conventional additives, e.g. for chewing gum, wherein at least one flavouring, aroma and/or other additive of which the release is to be delayed is contained in at least one phase of the basic composition, which phase consists of (a) at least one wax without functional groups, e.g. a paraffin wax, a polyethylene wax or a polyethylene glycol, which is substantially not miscible with the flavouring etc., and (b) at least one further wax having functional groups which contains said flavouring etc. in a stable solution or mixture, e.g. beeswax or a higher fatty alcohol, a higher fatty acid such as palmitic, stearic or arachic acid, or ester thereof; this further wax forms an homogenous mixture or a stable solution with the first wax. The ratio by weight between the two waxes may be from 1:10 to 10:1. Pharmaceutical products e.g. Dextrometorpham or dimethylaminohydroxy benzhydrylether can be thus included as additives to chewing gum.

Title: Coin collecting mechanism
IPC: G07F1/04
Filed: 1982-01-21
Abstract: In a coin collecting mechanism for a coin operated apparatus with an inclined coin storage duct for coins of uniform size a pivotable mounted collecting arm (5) serves as support for a coin (3) in the collecting mechanism. The arm (5) is controlled by a relay- actuated operating lever (7) which comprises a stop projection (10) on its end nearest to the coin duct, said projection (10) only allows the passage of a coin from the duct when the mechanism is in its non-actuated position and which lever at its other end has a pin (11) cooperating with a curved track (12) in the arm (5). Said curved track (12) comprises a first track portion (13) which is so arranged and positioned that the arm (5) is locked when the pin (11) is positioned in said first track portion (13). Thereby it is achieved that the actuating relay must act on the operating lever with only a small force in order to release the locking of the collecting arm, said arm then being pivoted downwardly for collection of the coin, the gravity of which contributes to the pivotal motion of the arm. <IMAGE>

Title: Stretching film longitudinally by tentering
Inventor: ROTTENSTEINER HANS
IPC: B29C55/16
Filed: 1982-05-26
Abstract: In a foil tentering apparatus, the tentering clips engage their driving member (which may be a sprocket chain) through a member, such as a sprocket wheel, which can be rotated to increase or decrease the separation of the clips in the longitudinal direction. The rotation is caused by activating members, such as sprocket chains 11, Fig. 1B or electrical contacts 29, Fig. 4 stationed along the path of the clips and engaging each clip as it passes. The invention is characterised in that the activating members are in segments, which follow one another without a gap so that their action is continuous. <IMAGE>

Title: Door selector
Inventor: PERRY KENNETH JAMES
IPC: E05F5/12
Filed: 1982-07-29
Abstract: A door selector for fitment to a pair of rebated doors (11, 12) to ensure that a leading door (11) closes before a trailing door (12) comprises a body (22) made in two parts (26, 27) from identical hollow metal extrusions with an abutment arm (23) secured between them, the body (22) being pivoted on a support (24). The distance by which the abutment arm (23) projects from the body (and hence the position at which the trailing door (12) is held open) is adjustable by means of a clamping screw (36) passing through a slot (39) in the arm (23) to clamp it between the body parts (26, 27). The limit of downward pivoting of the body relative to the support (24) is adjustable by a grub screw (34) acting as a stop against a stop portion (30) of the support (24). The striker arm (25) fixed on the leading door (11) raises the body (22) when door (11) is closed so permitting door (12) to close. <IMAGE>
