Filed: 1974-02-18
Abstract: 1422924 Radio signalling PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 18 Feb 1974 [28 Feb 1973] 7196/74 Heading H4L In a radio communication system comprising a plurality of stations each consisting of a transmitter for the transmission of a carrier wave modulated with speech and a receiver for the reception of such a signal from another station, each station transmits also a busy signal located in a frequency band beyond the speech signal band, means being provided for adding the speech signal to the busy signal before modulation of the carrier and for controlling the amplitude of the busy signal before said addition so that the envelope of the combined signal has a substantially constant amplitude. As described, the busy signal is a code consisting of two out of five tones. The output of the adding device is supplied to an amplitude detector which has a longer time constant than the duration of one period of the lowest speech signal frequency and supplies an output which is a measure of the deviation of the amplitude of the envelope of the combined signal from a fixed reference value. This output controls the gain of an amplifier for the busy signal. A switching signal having a frequency below the speech band may be added to the combination signal. In an alternative arrangement the amplitude of the busy signal may be controlled inversely as the output of the microphone.

Tampering with, detecting.- A mechanism for counting the number of times a travelling trunk has been opened comprises a casing 1 provided w.ith a hinged lid 2 and containing a numeral disc 5 exhibiting through a slot 4. The disc is formed as a ratchet wheel and is turned one tooth at a time by a plunger 6 carrying a pawl 7 and arranged in the path of movement of the lid of the trunk. The plunger is normally held raised by a spring 9 which can, however, be rendered ineffective by means of a pivoted stay 10. To prevent a, complete rotation of the disc a stop mounted on a spring 11 is disposed in the path of a pin 12; for resetting purposes this stop can be displaced by removing a stay 13 from engagement with the spring 11. An alternative method of preventing complete rotation consists in mutilating one tooth of the disc so that when the highest number has been counted depression of the plunger 6 cannot turn the disc; resetting in this case is effected by a separate pawl operated from outside the casing by normally locked means.

Title: Improvements in or relating to the manufacture of oil-modified alkyd resins
Inventor: GOURLEY SAMUEL
IPC: C08G63/48
Filed: 1950-03-29
Abstract: In making fatty oil-modified alkyd resins wherein an incompletely esterified polyhydric alcohol composition made by alcoholysis of a fatty oil with one or more polyhydric alcohols and containing in solution a calcium salt of a fatty acid is esterified with phthalic acid or anhydride, with or without maleic anhydride, clear haze-free resins are obtained by adding to the polyhydric alcohol composition an inorganic phosphate, which is soluble therein at any stage prior to the esterification in amount at least sufficient to precipitate the calcium salts present. Phosphates specified are phosphoric acid, ammonium phosphate, and sodium- and potassium - dihydrogen phosphates.  The precipitated calcium salts may be removed mechanically before the esterification.  According to the examples, in making a linseed oil-modified pentaerythritol phthalate, calcium formate (present as impurity) is removed by addition of (1) phosphoric acid, (3) potassium dihydrogen phosphate, and (4) sodium dihydrogen phosphate; and (2) in making a linseed oil-modified glycerol phthalate, calcium acetate (present as catalyst) is removed by adding phosphoric acid.
