Title: Coke ovens
IPC: C10B33/00
Filed: 1971-09-01
Abstract: 1368104 Discharging coke SIMON-CARVES Ltd 1 Sept 1971 [3 Oct 1970] 40722/71 Headings F4B and F4X Coke 10 is discharged from a coke oven through a guide grating 20 mounted on a car 19 to a quenching car 35 mounted on wheels 37. The car 19 travels on wheels 18 mounted on a platform carried by supports 16, and the guide grating 20 on the car 19 can be moved in the direction of the oven to rest against the door frame 30. A hood 32 is disposed on car 19 by means of a frame 31, and extends over the coke quench car 35. A pipe 45 extending from the interior of the hood 32 leads to a space 21 which forms a smoke exhaust main running alongside the oven battery. In the embodiment shown the exhaust main is formed by a trough 39 of liquid and a cover 42 attached to the outer wall of the trough. The liquid forms a seal between the pipe 45 and main 21 to prevent smoke escaping to the outside. In another embodiment the ends of the pipe from the hood extend into liquidfilled troughs (22) to provide a seal between the pipe (54) and an upper chamber of the exhaust main (52).

Abstract: 1473335 Silicon-containing Ti and Al chelates; RTV compositions IMPERIAL CHEMICAL INDUSTRIES Ltd 8 Sept 1975 [19 Sept 1974] 40881/74 Headings C3S and C3T Novel chelates have the formula AlRR<SP>1</SP> 2  or TiRR<SP>1</SP>(OR<SP>11</SP>) 2 , where R represents a siliconcontaining group chelated to the metal atom, R<SP>1</SP> represents an optionally silicon-containing group chelated to the metal atom, and R<SP>11</SP> is a hydrocarbyl or trialkylsilyl group. They may be prepared by addition of a compound containing at least one SiH group to an unsaturated chelating agent before or after reaction thereof with a suitable Al or Ti compound. In Examples 1 and 2 (EtO) 2 MeSiH is added to ethyl 2-allylacetylacetate (Example 1) or 3-allyl-acetylacetone (Example 2) in 1 : 1 molar ratio i.p.c. PtCl 2 2Et 2 S to give the silylated chelating agents; these are then reacted alone in 2 : 1 molar ratio with (i-PrO) 4 Ti (Examples 1 and 2), (i-PrO) 2 Ti(OSiMe 3 ) 2  (Example 6) or (i-PrO) 3 Ti- OSiMe 3  (Example 7), or followed by the unmodified ethyl acetoacetate or acetylacetone in 1 : 1 : 1 molar ratio with (iPrO) 4 Ti (Examples 4 and 5); the ester is reacted in 3 : 1 molar ratio with (iPrO) 3 Al; or the silylated diketone with unmodified acetylacetone and (iPrO) 3 Al in 2 : 1 : 1 molar ratio. In Example 3 the siloxane Me 3 SiO(Me 2 SiO) 35À5 (MeHSiO) 12À5 SiMe 3  is added i.p.o. PtCl 2 .2Et 2 S to the product from (iPrO) 4 Ti, allylacetylacetone and acetylacetone in 1 : 1 : 1 molar ratio; this is used to prime Al or as an additive for an RTV silicone rubber composition. In Examples 10 and 11 allylacetylacetone is reacted with alum to give the Al trichelate, to which is then added 2 molar parts of (EtO) 2 Me- SiH or (MeOC 2 H 4 O) 2 MeSiH. In Examples 12-20 6 p.b.w. of various of the above products and 0À4 p.b.w. of stannous octoate are used to catalyse 100 p.b.w. of a base consisting of 40 wt. per cent CaCO 3  and 60 wt. per cent of (A) a 3 : 2 : 1 mixture of polydimethylsiloxane diols of viscosity 4700 and 60,000 cP/25‹ C. and a trimethylsilyl - terminated polydimethylsiloxane of 350 cP/25‹ C., or (B) a product from a polydimethylsiloxane diol of 3900 cP/25‹ C. and methylsilyl triacetate, giving RTV rubbers.

Abstract: 1375769 Touch responsive switching systems A F KAY 6 Sept 1972 [27 Sept 1971] 41331/72 Heading GIN [Also in Divisions H2 and H3] A remote control arrangement for a switching device 41 of the type which makes and breaks on successive actuations, e.g. a ratchet switch, comprises an electronic switch (e.g. triac 30) in series therewith across an A.C. supply and controlled by a relatively low voltage circuit which in response to a remote switch 18 provides a single pulse sufficient to energize the electronic switch during one half-cycle of the supply only. In Fig. 1, the low voltage for the control circuit is provided by a transformer T-1 and the operation of switch 18, which may be in a touch plate, causes a capacitor 20 to charge to produce a short pulse for triggering switch 30. The triac goes off at the end of the half cycle and does not re-operate unless switch 18 is first opened to allow the capacitor 20 to discharge, and then re-operate. In Fig. 5, the low voltage is provided across a Zener diode 31 and is a substantially rectangular wave. This is differentiated by a capacitor 42 when switch 44 is made, so that the transistor conducts, discharging a capacitor 52 into the gate of the triac. The latter ceases to conduct at the end of the cycle and the time constant of the differentiator is such that T3 is maintained conductive so long as 34 is made and the triac does not re-trigger. The triggering pulse occurs close to the zero-crossing of the supply.  The circuit is suitable for switching a domestic light, the restriction of the operating current to half a cycle minimizing the heating of the ratchet switch coil.
