Title: Deceleration meter
IPC: G01P1/12
Filed: 1963-10-09
Abstract: 1, 055, 970. Recording deceleration and brake pedal pressure. R, SCHLAICH, [trading as MOTO METER HERMANN SCHLAICH] Oct. 9, 1963 [Oct. 10, 1962], No. 39899/63. Headings G1J, G1K and G1W. A deceleration meter, particularly adapted for measuring retardation dependent on pedal pressure when a vehicle is braked, has an inertia weight which carries out a movement determined by the forces of inertia acting on it as a result of the negative acceleration, this movement being recorded by a writing instrument on a chart driven by clockwork mechanism at a uniform speed in which the device which records the deceleration is combined in a common housing with a measuring device controlled by the associated pedal pressure. The foot pedal 74 is connected through a fluid operated transmission line 70, (see Fig. 1 not shown), to a piston rod 46 slidable in cylinder 42, the rod 46 being connected to an arm 50 of a pivoted spring-loaded lever 54 supporting a writing point 62. The piston rod 46 is also connected to a brake disc 90 of a driving mechanism 92 by cords 80, 88. A chart 170 is moved along guide plate 18, (see Figs. 1 and 3 not shown), by pins 120 carried on a rotatable spindle 108 driven by mechanism 92. An inertia weight 130 is slidably mounted on guide rods 132, 134 and carries a flat spring 142 bearing a writing point 144. In use, when pressure is applied to the diaphragm 74 e.g. during braking, drive unit 41 is set in motion through movement of piston rod 46, and pin 62 moves across the chart 170. Simultaneously the weight 130 makes corresponding movements which are recorded by point 144. The inertia weight 130 may be locked in position by means 138, 140 when the device is not in use. A spirit level 160 is provided.

Title: A process for dyeing natural or regenerated cellulose
IPC: C09B43/00
Filed: 1965-09-22
Abstract: Natural e.g. cotton, linen, or regenerated cellulose e.g viscose is dyed with organic mono- or polyazo dyestuffs resistant to discharge in an alkaline medium and free from vattable polycylic quinones, acid hydroxyl groups, nitro, amino and ureido groups and which contain for each azo bridge at least one and at most two sulphonic, sulphates or carbonyl groups and passes a higher affinity in the partially reduced state and wherein in the case of a polyazo dye the azo linkages are not bound directly to the same aromatic residue, the process being carried out in an alkaline medium in presence of a strong-reducing agent which reduces at least one azo group to the hydrazo stage, and the dye being reoxidised on the fibre to the azo compound.  The term "acid hydroxyl" means hydroxyl groups bound directly to a carbon atom of a -C=C-double bond.  The dyes may contain one or more heterocyclic five-membered rings containing oxygen and/or nitrogen and/or sulphur, e.g. thiazole, oxazole, imidazole, oxidiazole or triazole and/or a stilbene or carboxylic acid amide group. Dyeing may be carried out using exhaustion or padding methods optionally in presence of vat dyes or non-vatting anthraquinone dyes and inorganic salts e.g. alkali metal chlorides or sulphates.  Preferred reducing agents are sodium hydrosulphite and/or thiouren dioxide and a -hydroxyalkane sulphinic acid if desired together with a redox catalyst.  Several examples describe dyeing with a mixture azo and vat dyes which may be in solution or fine suspension.

Title: Automatic telephone call answering devices
IPC: H04Q3/00
Filed: 1972-09-08
Abstract: 1397841 Automatic exchange systems GTE INTERNATIONAL Inc 31 July 1973 [8 Sept 1972] 41947/72 Heading H4K A centralized device is arranged for answering calls, transmitting a pre-recorded message to each caller identifying services or extensions available, to detect a signal from the caller identifying a caller by its time of arrival and to transmit a code corresponding to that identity to a switch unit adapted to connect the caller to the identified service or connection. In one detailed embodiment the apparatus is associated with a PABX with in-dialling facilities. A closed loop tape having three parallel tracks runs continuously. In response to an incoming call, track 1 is connected to line when a start tone on that track is detected. It carries an acknowledgement signal, an explanation asking the caller to give a "yes" answer to one of the following questions, and the questions which ask whether the caller knows the extension he requires and whether he wishes to speak about particular types of business associated with different extensions. If the caller knows the extension he can be connected (if he has a multifrequency sender) to dial that extension or if not be connected to tracks two and three in succession which respectively ask whether the first and second digits of that extension are particular digits quoting these in succession. After each possible alternative on each track a pause is left in which he can give a "yes" reply and during every such pause the line is connected to a signal detector, a tone on the appropriate track being used for this purpose. A counter advanced in synchronism with track 1 produces via a diode recording matrix codes identifying the extension and a second counter advanced in synchronism with each of tracks 2 and 3 produces in succession codes corresponding to the digits of the extensions. As signals from the caller are detected the corresponding codes currently being produced are stored and transmitted to the exchange identifying the wanted extension or used to initiate impulsing into a stronger type PABX with in-dialling. Alternatively the equipment may be used in a public exchange to route callers to special service equipment in place of an operator. Other PABX arrangements with operators also involved are described.

As shown, the first damping device 25 is mounted on the hub part 10 and acts between the hub flange 16 and the side plate 14 of the disc to exercise a damping effect in the first spring stage which involves a spring 17 disposed in apertures 18, 19 of equal circumferential length in the hub flange 16 and side plates 13, 14 respectively. The second damping device 26 is mounted on a sleeve 27 of the control plate 28 and acts between the control plate and side plate 13 and comes into effect with the two springs 20 of the second spring stage in which the apertures 21 in the hub flange 16 are larger circumferentially than the apertures 22 in the side plates 13, 14. The apertures for the two springs 24 of the third spring stage are of greater circumferential difference. The control spring 29 is closely embraced by arms 31 of the control plate and is inserted in the apertures 30 in the side plates under initial stress.
